-    elf: Fix force_first handling in dlclose (bug 30981)
-    
-    The force_first parameter was ineffective because the dlclose'd
-    object was not necessarily the first in the maps array.  Also
-    enable force_first handling unconditionally, regardless of namespace.
-    The initial object in a namespace should be destructed first, too.
-    
-    The _dl_sort_maps_dfs function had early returns for relocation
-    dependency processing which broke force_first handling, too, and
-    this is fixed in this change as well.

-    nscd: Skip unusable entries in first pass in prune_cache (bug 30800)
-    
-    Previously, if an entry was marked unusable for any reason, but had
-    not timed out yet, the assert would trigger.
-    
-    One way to get into such state is if a data change is detected during
-    re-validation of an entry.  This causes the entry to be marked as not
-    usable.  If exits nscd soon after that, then the clock jumps
-    backwards, and nscd restarted, the cache re-validation run after
-    startup triggers the removed assert.
-    
-    The change is more complicated than just the removal of the assert
-    because entries marked as not usable should be garbage-collected in
-    the second pass.  To make this happen, it is necessary to update some
-    book-keeping data.

-Subject: [PATCH] x86-64 memchr/wmemchr: Properly handle the length parameter
- [BZ# 24097]
-Content-type: text/plain; charset=UTF-8
-
-On x32, the size_t parameter may be passed in the lower 32 bits of a
-64-bit register with the non-zero upper 32 bits.  The string/memory
-functions written in assembly can only use the lower 32 bits of a
-64-bit register as length or must clear the upper 32 bits before using
-the full 64-bit register for length.
-
-This pach fixes memchr/wmemchr for x32.  Tested on x86-64 and x32.  On
-x86-64, libc.so is the same with and withou the fix.
-
-	[BZ# 24097]
-	CVE-2019-6488
-	* sysdeps/x86_64/memchr.S: Use RDX_LP for length.  Clear the
-	upper 32 bits of RDX register.
-	* sysdeps/x86_64/multiarch/memchr-avx2.S: Likewise.
-	* sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-memchr and
-	tst-size_t-wmemchr.
-	* sysdeps/x86_64/x32/test-size_t.h: New file.
-	* sysdeps/x86_64/x32/tst-size_t-memchr.c: Likewise.
-	* sysdeps/x86_64/x32/tst-size_t-wmemchr.c: Likewise.

-Subject: [PATCH] x86: Fix __wcsncmp_avx2 in strcmp-avx2.S [BZ# 28755]
-Content-type: text/plain; charset=UTF-8
-
-Fixes [BZ# 28755] for wcsncmp by redirecting length >= 2^56 to
-__wcscmp_avx2. For x86_64 this covers the entire address range so any
-length larger could not possibly be used to bound `s1` or `s2`.
-
-test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass.

-Subject: [PATCH] x86: Small improvements for wcslen
-Content-type: text/plain; charset=UTF-8
-
-Just a few QOL changes.
-    1. Prefer `add` > `lea` as it has high execution units it can run
-       on.
-    2. Don't break macro-fusion between `test` and `jcc`
-    3. Reduce code size by removing gratuitous padding bytes (-90
-       bytes).
-
-geometric_mean(N=20) of all benchmarks New / Original: 0.959
-
-All string/memory tests pass.

-
-    x86: Shrink memcmp-sse4.S code size
-
-The new memcmp-sse2 implementation is also faster.
-
-geometric_mean(N=20) of page cross cases SSE2 / SSE4: 0.905
-
-Note there are two regressions preferring SSE2 for Size = 1 and Size =
-65.
-
-Size = 1:
-size, align0, align1, ret, New Time/Old Time
-   1,      1,      1,   0,               1.2
-   1,      1,      1,   1,             1.197
-   1,      1,      1,  -1,               1.2
-
-This is intentional. Size == 1 is significantly less hot based on
-profiles of GCC11 and Python3 than sizes [4, 8] (which is made
-hotter).
-
-Python3 Size = 1        -> 13.64%
-Python3 Size = [4, 8]   -> 60.92%
-
-GCC11   Size = 1        ->  1.29%
-GCC11   Size = [4, 8]   -> 33.86%
-
-size, align0, align1, ret, New Time/Old Time
-   4,      4,      4,   0,             0.622
-   4,      4,      4,   1,             0.797
-   4,      4,      4,  -1,             0.805
-   5,      5,      5,   0,             0.623

-   9,      9,      9,   0,             0.625
-
-Size = 65:
-size, align0, align1, ret, New Time/Old Time
-  65,      0,      0,   0,             1.103
-  65,      0,      0,   1,             1.216
-  65,      0,      0,  -1,             1.227
-  65,     65,      0,   0,             1.091
-  65,      0,     65,   1,              1.19
-  65,     65,     65,  -1,             1.215
-
-This is because A) the checks in range [65, 96] are now unrolled 2x
-and B) because smaller values <= 16 are now given a hotter path. By
-contrast the SSE4 version has a branch for Size = 80. The unrolled
-version has get better performance for returns which need both
-comparisons.
-
-size, align0, align1, ret, New Time/Old Time
- 128,      4,      8,   0,             0.858
- 128,      4,      8,   1,             0.879
- 128,      4,      8,  -1,             0.888
-
-As well, out of microbenchmark environments that are not full
-predictable the branch will have a real-cost.

-Subject: [PATCH] x86: Cleanup page cross code in memcmp-avx2-movbe.S
-Content-type: text/plain; charset=UTF-8
-
-Old code was both inefficient and wasted code size. New code (-62
-bytes) and comparable or better performance in the page cross case.
-
-geometric_mean(N=20) of page cross cases New / Original: 0.960

-Subject: [PATCH] x86: Optimize {str|wcs}rchr-sse2
-Content-type: text/plain; charset=UTF-8
-
-The new code unrolls the main loop slightly without adding too much
-overhead and minimizes the comparisons for the search CHAR.
-
-Geometric Mean of all benchmarks New / Old: 0.741
-See email for all results.
-
-Full xcheck passes on x86_64 with and without multiarch enabled.
-Reviewed-by: H.J. Lu <hjl.tools@gmail.com>

-Subject: [PATCH] x86: Optimize {str|wcs}rchr-avx2
-Content-type: text/plain; charset=UTF-8
-
-The new code unrolls the main loop slightly without adding too much
-overhead and minimizes the comparisons for the search CHAR.
-
-Geometric Mean of all benchmarks New / Old: 0.832
-See email for all results.
-
-Full xcheck passes on x86_64 with and without multiarch enabled.
-Reviewed-by: H.J. Lu <hjl.tools@gmail.com>

-Subject: [PATCH] x86: Optimize {str|wcs}rchr-evex
-Content-type: text/plain; charset=UTF-8
-
-The new code unrolls the main loop slightly without adding too much
-overhead and minimizes the comparisons for the search CHAR.
-
-Geometric Mean of all benchmarks New / Old: 0.755
-See email for all results.
-
-Full xcheck passes on x86_64 with and without multiarch enabled.
-Reviewed-by: H.J. Lu <hjl.tools@gmail.com>

-Subject: [PATCH] sysdeps: Add 'get_fast_jitter' interace in fast-jitter.h
-Content-type: text/plain; charset=UTF-8
-
-'get_fast_jitter' is meant to be used purely for performance
-purposes. In all cases it's used it should be acceptable to get no
-randomness (see default case). An example use case is in setting
-jitter for retries between threads at a lock. There is a
-performance benefit to having jitter, but only if the jitter can
-be generated very quickly and ultimately there is no serious issue
-if no jitter is generated.
-
-The implementation generally uses 'HP_TIMING_NOW' iff it is
-inlined (avoid any potential syscall paths).

-Subject: [PATCH] nptl: Add backoff mechanism to spinlock loop
-Content-type: text/plain; charset=UTF-8
-
-When mutiple threads waiting for lock at the same time, once lock owner
-releases the lock, waiters will see lock available and all try to lock,
-which may cause an expensive CAS storm.
-
-Binary exponential backoff with random jitter is introduced. As try-lock
-attempt increases, there is more likely that a larger number threads
-compete for adaptive mutex lock, so increase wait time in exponential.
-A random jitter is also added to avoid synchronous try-lock from other
-threads.
-
-v2: Remove read-check before try-lock for performance.
-
-v3:
-1. Restore read-check since it works well in some platform.
-2. Make backoff arch dependent, and enable it for x86_64.
-3. Limit max backoff to reduce latency in large critical section.
-
-v4: Fix strict-prototypes error in sysdeps/nptl/pthread_mutex_backoff.h
-
-v5: Commit log updated for regression in large critical section.
-
-Result of pthread-mutex-locks bench
-
-Test Platform: Xeon 8280L (2 socket, 112 CPUs in total)
-First Row: thread number
-First Col: critical section length
-Values: backoff vs upstream, time based, low is better

-Subject: [PATCH] x86: Fallback {str|wcs}cmp RTM in the ncmp overflow case [BZ
- #28896]
-Content-type: text/plain; charset=UTF-8
-
-In the overflow fallback strncmp-avx2-rtm and wcsncmp-avx2-rtm would
-call strcmp-avx2 and wcscmp-avx2 respectively. This would have
-not checks around vzeroupper and would trigger spurious
-aborts. This commit fixes that.
-
-test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass on
-AVX2 machines with and without RTM.

-Subject: [PATCH] x86: Set Prefer_No_VZEROUPPER and add Prefer_AVX2_STRCMP
-Content-type: text/plain; charset=UTF-8
-
-1. Set Prefer_No_VZEROUPPER if RTM is usable to avoid RTM abort triggered
-by VZEROUPPER inside a transactionally executing RTM region.
-2. Since to compare 2 32-byte strings, 256-bit EVEX strcmp requires 2
-loads, 3 VPCMPs and 2 KORDs while AVX2 strcmp requires 1 load, 2 VPCMPEQs,
-1 VPMINU and 1 VPMOVMSKB, AVX2 strcmp is faster than EVEX strcmp.  Add
-Prefer_AVX2_STRCMP to prefer AVX2 strcmp family functions.

-Subject: [PATCH] x86-64: Add memset family functions with 256-bit EVEX
-Content-type: text/plain; charset=UTF-8
-
-Update ifunc-memset.h/ifunc-wmemset.h to select the function optimized
-with 256-bit EVEX instructions using YMM16-YMM31 registers to avoid RTM
-abort with usable AVX512VL and AVX512BW since VZEROUPPER isn't needed at
-function exit.

-Subject: [PATCH] x86: Add string/memory function tests in RTM region
-Content-type: text/plain; charset=UTF-8
-
-At function exit, AVX optimized string/memory functions have VZEROUPPER
-which triggers RTM abort.   When such functions are called inside a
-transactionally executing RTM region, RTM abort causes severe performance
-degradation.  Add tests to verify that string/memory functions won't
-cause RTM abort in RTM region.

-Subject: [PATCH] x86-64: Use ZMM16-ZMM31 in AVX512 memset family functions
-Content-type: text/plain; charset=UTF-8
-
-Update ifunc-memset.h/ifunc-wmemset.h to select the function optimized
-with AVX512 instructions using ZMM16-ZMM31 registers to avoid RTM abort
-with usable AVX512VL and AVX512BW since VZEROUPPER isn't needed at
-function exit.

-Subject: [PATCH] x86-64 memcmp/wmemcmp: Properly handle the length parameter
- [BZ# 24097]
-Content-type: text/plain; charset=UTF-8
-
-On x32, the size_t parameter may be passed in the lower 32 bits of a
-64-bit register with the non-zero upper 32 bits.  The string/memory
-functions written in assembly can only use the lower 32 bits of a
-64-bit register as length or must clear the upper 32 bits before using
-the full 64-bit register for length.
-
-This pach fixes memcmp/wmemcmp for x32.  Tested on x86-64 and x32.  On
-x86-64, libc.so is the same with and withou the fix.
-
-	[BZ# 24097]
-	CVE-2019-6488
-	* sysdeps/x86_64/multiarch/memcmp-avx2-movbe.S: Use RDX_LP for
-	length.  Clear the upper 32 bits of RDX register.
-	* sysdeps/x86_64/multiarch/memcmp-sse4.S: Likewise.
-	* sysdeps/x86_64/multiarch/memcmp-ssse3.S: Likewise.
-	* sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-memcmp and
-	tst-size_t-wmemcmp.
-	* sysdeps/x86_64/x32/tst-size_t-memcmp.c: New file.
-	* sysdeps/x86_64/x32/tst-size_t-wmemcmp.c: Likewise.

-Subject: [PATCH] x86: Optimize memchr-avx2.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. This commit optimizes memchr-avx2.S. The optimizations include
-replacing some branches with cmovcc, avoiding some branches entirely
-in the less_4x_vec case, making the page cross logic less strict,
-asaving a few instructions the in loop return loop. test-memchr,
-test-rawmemchr, and test-wmemchr are all passing.

-Subject: [PATCH] x86: Fix overflow bug with wmemchr-sse2 and wmemchr-avx2 [BZ
- #27974]
-Content-type: text/plain; charset=UTF-8
-
-This commit fixes the bug mentioned in the previous commit.
-
-The previous implementations of wmemchr in these files relied
-on n * sizeof(wchar_t) which was not guranteed by the standard.
-
-The new overflow tests added in the previous commit now
-pass (As well as all the other tests).

-Subject: [PATCH] x86: Optimize strlen-avx2.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. This commit optimizes strlen-avx2.S. The optimizations are
-mostly small things but they add up to roughly 10-30% performance
-improvement for strlen. The results for strnlen are bit more
-ambiguous. test-strlen, test-strnlen, test-wcslen, and test-wcsnlen
-are all passing.

-From: Noah Goldstein <goldstein.w.n@gmail.com>

-Subject: [PATCH] x86: Optimize memchr-evex.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. This commit optimizes memchr-evex.S. The optimizations include
-replacing some branches with cmovcc, avoiding some branches entirely
-in the less_4x_vec case, making the page cross logic less strict,
-saving some ALU in the alignment process, and most importantly
-increasing ILP in the 4x loop. test-memchr, test-rawmemchr, and
-test-wmemchr are all passing.

-Subject: [PATCH] x86-64: Move strlen.S to multiarch/strlen-vec.S
-Content-type: text/plain; charset=UTF-8
-
-Since strlen.S contains SSE2 version of strlen/strnlen and SSE4.1
-version of wcslen/wcsnlen, move strlen.S to multiarch/strlen-vec.S
-and include multiarch/strlen-vec.S from SSE2 and SSE4.1 variants.
-This also removes the unused symbols, __GI___strlen_sse2 and
-__GI___wcsnlen_sse4_1.

-Subject: [PATCH] x86-64: Add wcslen optimize for sse4.1
-Content-type: text/plain; charset=UTF-8
-
-No bug. This comment adds the ifunc / build infrastructure
-necessary for wcslen to prefer the sse4.1 implementation
-in strlen-vec.S. test-wcslen.c is passing.

-Subject: [PATCH] x86-64 memcpy: Properly handle the length parameter [BZ#
- 24097]
-Content-type: text/plain; charset=UTF-8
-
-On x32, the size_t parameter may be passed in the lower 32 bits of a
-64-bit register with the non-zero upper 32 bits.  The string/memory
-functions written in assembly can only use the lower 32 bits of a
-64-bit register as length or must clear the upper 32 bits before using
-the full 64-bit register for length.
-
-This pach fixes memcpy for x32.  Tested on x86-64 and x32.  On x86-64,
-libc.so is the same with and withou the fix.
-
-	[BZ# 24097]
-	CVE-2019-6488
-	* sysdeps/x86_64/multiarch/memcpy-ssse3-back.S: Use RDX_LP for
-	length.  Clear the upper 32 bits of RDX register.
-	* sysdeps/x86_64/multiarch/memcpy-ssse3.S: Likewise.
-	* sysdeps/x86_64/multiarch/memmove-avx512-no-vzeroupper.S:
-	Likewise.
-	* sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S:
-	Likewise.
-	* sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-memcpy.
-	tst-size_t-wmemchr.
-	* sysdeps/x86_64/x32/tst-size_t-memcpy.c: New file.

-Subject: [PATCH] x86: Fix overflow bug in wcsnlen-sse4_1 and wcsnlen-avx2 [BZ
- #27974]
-Content-type: text/plain; charset=UTF-8
-
-This commit fixes the bug mentioned in the previous commit.
-
-The previous implementations of wmemchr in these files relied
-on maxlen * sizeof(wchar_t) which was not guranteed by the standard.
-
-The new overflow tests added in the previous commit now
-pass (As well as all the other tests).

-Subject: [PATCH] x86: Optimize strlen-evex.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. This commit optimizes strlen-evex.S. The
-optimizations are mostly small things but they add up to roughly
-10-30% performance improvement for strlen. The results for strnlen are
-bit more ambiguous. test-strlen, test-strnlen, test-wcslen, and
-test-wcsnlen are all passing.

-Subject: [PATCH] x86: Check RTM_ALWAYS_ABORT for RTM [BZ #28033]
-Content-type: text/plain; charset=UTF-8
-
-From
-
-https://www.intel.com/content/www/us/en/support/articles/000059422/processors.html
-
-* Intel TSX will be disabled by default.
-* The processor will force abort all Restricted Transactional Memory (RTM)
-  transactions by default.
-* A new CPUID bit CPUID.07H.0H.EDX[11](RTM_ALWAYS_ABORT) will be enumerated,
-  which is set to indicate to updated software that the loaded microcode is
-  forcing RTM abort.
-* On processors that enumerate support for RTM, the CPUID enumeration bits
-  for Intel TSX (CPUID.07H.0H.EBX[11] and CPUID.07H.0H.EBX[4]) continue to
-  be set by default after microcode update.
-* Workloads that were benefited from Intel TSX might experience a change
-  in performance.
-* System software may use a new bit in Model-Specific Register (MSR) 0x10F
-  TSX_FORCE_ABORT[TSX_CPUID_CLEAR] functionality to clear the Hardware Lock
-  Elision (HLE) and RTM bits to indicate to software that Intel TSX is
-  disabled.
-
-1. Add RTM_ALWAYS_ABORT to CPUID features.
-2. Set RTM usable only if RTM_ALWAYS_ABORT isn't set.  This skips the
-string/tst-memchr-rtm etc. testcases on the affected processors, which
-always fail after a microcde update.
-3. Check RTM feature, instead of usability, against /proc/cpuinfo.
-
-This fixes BZ #28033.

-
-    x86-64: Add wcslen optimize for sse4.1
-
-Added wcsnlen-sse4.1 to the wcslen ifunc implementation list and did
-not add wcslen-sse4.1 to wcslen ifunc implementation list. This commit
-fixes that by removing wcsnlen-sse4.1 from the wcslen ifunc
-implementation list and adding wcslen-sse4.1 to the ifunc
-implementation list.
-
-Testing:
-test-wcslen.c, test-rsi-wcslen.c, and test-rsi-strlen.c are passing as
-well as all other tests in wcsmbs and string.

-Subject: [PATCH] x86: Fallback {str|wcs}cmp RTM in the ncmp overflow case [BZ
- #28896]
-Content-type: text/plain; charset=UTF-8
-
-In the overflow fallback strncmp-avx2-rtm and wcsncmp-avx2-rtm would
-call strcmp-avx2 and wcscmp-avx2 respectively. This would have
-not checks around vzeroupper and would trigger spurious
-aborts. This commit fixes that.
-
-test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass on
-AVX2 machines with and without RTM.

- #25966]
-Content-type: text/plain; charset=UTF-8
-
-Since __x86_shared_non_temporal_threshold is defined as
-
-long int __x86_shared_non_temporal_threshold;
-
-and long int is 4 bytes for x32, use RDX_LP to compare against
-__x86_shared_non_temporal_threshold in assembly code.

-Subject: [PATCH] x86-64: Refactor and improve performance of strchr-avx2.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. Just seemed the performance could be improved a bit. Observed
-and expected behavior are unchanged. Optimized body of main
-loop. Updated page cross logic and optimized accordingly. Made a few
-minor instruction selection modifications. No regressions in test
-suite. Both test-strchrnul and test-strchr passed.

-Subject: [PATCH] x86-64: Avoid rep movsb with short distance [BZ #27130]
-Content-type: text/plain; charset=UTF-8
-
-When copying with "rep movsb", if the distance between source and
-destination is N*4GB + [1..63] with N >= 0, performance may be very
-slow.  This patch updates memmove-vec-unaligned-erms.S for AVX and
-AVX512 versions with the distance in RCX:
-
-	cmpl	$63, %ecx
-	// Don't use "rep movsb" if ECX <= 63
-	jbe	L(Don't use rep movsb")
-	Use "rep movsb"
-
-Benchtests data with bench-memcpy, bench-memcpy-large, bench-memcpy-random
-and bench-memcpy-walk on Skylake, Ice Lake and Tiger Lake show that its
-performance impact is within noise range as "rep movsb" is only used for
-data size >= 4KB.

-Subject: [PATCH] x86: Update large memcpy case in memmove-vec-unaligned-erms.S
-Content-type: text/plain; charset=UTF-8
-
-No Bug. This commit updates the large memcpy case (no overlap). The
-update is to perform memcpy on either 2 or 4 contiguous pages at
-once. This 1) helps to alleviate the affects of false memory aliasing
-when destination and source have a close 4k alignment and 2) In most
-cases and for most DRAM units is a modestly more efficient access
-pattern. These changes are a clear performance improvement for
-VEC_SIZE =16/32, though more ambiguous for VEC_SIZE=64. test-memcpy,
-test-memccpy, test-mempcpy, test-memmove, and tst-memmove-overflow all
-pass.

-Subject: [PATCH] x86-64 memrchr: Properly handle the length parameter [BZ#
- 24097]
-Content-type: text/plain; charset=UTF-8
-
-On x32, the size_t parameter may be passed in the lower 32 bits of a
-64-bit register with the non-zero upper 32 bits.  The string/memory
-functions written in assembly can only use the lower 32 bits of a
-64-bit register as length or must clear the upper 32 bits before using
-the full 64-bit register for length.
-
-This pach fixes memrchr for x32.  Tested on x86-64 and x32.  On x86-64,
-libc.so is the same with and withou the fix.
-
-	[BZ# 24097]
-	CVE-2019-6488
-	* sysdeps/x86_64/memrchr.S: Use RDX_LP for length.
-	* sysdeps/x86_64/multiarch/memrchr-avx2.S: Likewise.
-	* sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-memrchr.
-	* sysdeps/x86_64/x32/tst-size_t-memrchr.c: New file.

-Subject: [PATCH] x86: Optimize strchr-avx2.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. This commit optimizes strchr-avx2.S. The optimizations are all
-small things such as save an ALU in the alignment process, saving a
-few instructions in the loop return, saving some bytes in the main
-loop, and increasing the ILP in the return cases. test-strchr,
-test-strchrnul, test-wcschr, and test-wcschrnul are all passing.

-Subject: [PATCH] x86: Optimize strchr-evex.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. This commit optimizes strchr-evex.S. The optimizations are
-mostly small things such as save an ALU in the alignment process,
-saving a few instructions in the loop return. The one significant
-change is saving 2 instructions in the 4x loop. test-strchr,
-test-strchrnul, test-wcschr, and test-wcschrnul are all passing.

-Subject: [PATCH] x86: Add EVEX optimized memchr family not safe for RTM
-Content-type: text/plain; charset=UTF-8
-
-No bug.
-
-This commit adds a new implementation for EVEX memchr that is not safe
-for RTM because it uses vzeroupper. The benefit is that by using
-ymm0-ymm15 it can use vpcmpeq and vpternlogd in the 4x loop which is
-faster than the RTM safe version which cannot use vpcmpeq because
-there is no EVEX encoding for the instruction. All parts of the
-implementation aside from the 4x loop are the same for the two
-versions and the optimization is only relevant for large sizes.

-From: Noah Goldstein <goldstein.w.n@gmail.com>
-Date: Mon, 17 May 2021 13:56:52 -0400
-Subject: [PATCH] x86: Optimize memcmp-avx2-movbe.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. This commit optimizes memcmp-avx2.S. The optimizations include
-adding a new vec compare path for small sizes, reorganizing the entry
-control flow, and removing some unnecissary ALU instructions from the
-main loop. test-memcmp and test-wmemcmp are both passing.

-Subject: [PATCH] x86: Optimize memcmp-evex-movbe.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. This commit optimizes memcmp-evex.S. The optimizations include
-adding a new vec compare path for small sizes, reorganizing the entry
-control flow, removing some unnecissary ALU instructions from the main
-loop, and most importantly replacing the heavy use of vpcmp + kand
-logic with vpxor + vptern. test-memcmp and test-wmemcmp are both
-passing.

-Subject: [PATCH] x86: Improve memset-vec-unaligned-erms.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. This commit makes a few small improvements to
-memset-vec-unaligned-erms.S. The changes are 1) only aligning to 64
-instead of 128. Either alignment will perform equally well in a loop
-and 128 just increases the odds of having to do an extra iteration
-which can be significant overhead for small values. 2) Align some
-targets and the loop. 3) Remove an ALU from the alignment process. 4)
-Reorder the last 4x VEC so that they are stored after the loop. 5)
-Move the condition for leq 8x VEC to before the alignment
-process. test-memset and test-wmemset are both passing.

-Subject: [PATCH] x86: Remove unnecessary overflow check from wcsnlen-sse4_1.S
-Content-type: text/plain; charset=UTF-8
-
-No bug. The way wcsnlen will check if near the end of maxlen
-is the following macro:
-
-	mov	%r11, %rsi;	\
-	subq	%rax, %rsi;	\
-	andq	$-64, %rax;	\
-	testq	$-64, %rsi;	\
-	je	L(strnlen_ret)
-
-Which words independently of s + maxlen overflowing. So the
-second overflow check is unnecissary for correctness and
-just extra overhead in the common no overflow case.
-
-test-strlen.c, test-wcslen.c, test-strnlen.c and test-wcsnlen.c are
-all passing

-Subject: [PATCH] x86-64 memset/wmemset: Properly handle the length parameter
- [BZ# 24097]
-Content-type: text/plain; charset=UTF-8
-
-On x32, the size_t parameter may be passed in the lower 32 bits of a
-64-bit register with the non-zero upper 32 bits.  The string/memory
-functions written in assembly can only use the lower 32 bits of a
-64-bit register as length or must clear the upper 32 bits before using
-the full 64-bit register for length.
-
-This pach fixes memset/wmemset for x32.  Tested on x86-64 and x32.  On
-x86-64, libc.so is the same with and withou the fix.
-
-	[BZ# 24097]
-	CVE-2019-6488
-	* sysdeps/x86_64/multiarch/memset-avx512-no-vzeroupper.S: Use
-	RDX_LP for length.  Clear the upper 32 bits of RDX register.
-	* sysdeps/x86_64/multiarch/memset-vec-unaligned-erms.S: Likewise.
-	* sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-wmemset.
-	* sysdeps/x86_64/x32/tst-size_t-memset.c: New file.
-	* sysdeps/x86_64/x32/tst-size_t-wmemset.c: Likewise.

-Content-type: text/plain; charset=UTF-8
-
-Fixes [BZ# 28755] for wcsncmp by redirecting length >= 2^56 to
-__wcscmp_evex. For x86_64 this covers the entire address range so any
-length larger could not possibly be used to bound `s1` or `s2`.
-
-test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass.

-Subject: [PATCH] x86: Modify ENTRY in sysdep.h so that p2align can be
- specified
-Content-type: text/plain; charset=UTF-8
-
-No bug.
-
-This change adds a new macro ENTRY_P2ALIGN which takes a second
-argument, log2 of the desired function alignment.
-
-The old ENTRY(name) macro is just ENTRY_P2ALIGN(name, 4) so this
-doesn't affect any existing functionality.

-Subject: [PATCH] x86: Optimize memcmp-evex-movbe.S for frontend behavior and
- size
-Content-type: text/plain; charset=UTF-8
-
-No bug.
-
-The frontend optimizations are to:
-1. Reorganize logically connected basic blocks so they are either in
-   the same cache line or adjacent cache lines.
-2. Avoid cases when basic blocks unnecissarily cross cache lines.
-3. Try and 32 byte align any basic blocks possible without sacrificing
-   code size. Smaller / Less hot basic blocks are used for this.
-
-Overall code size shrunk by 168 bytes. This should make up for any
-extra costs due to aligning to 64 bytes.
-
-In general performance before deviated a great deal dependending on
-whether entry alignment % 64 was 0, 16, 32, or 48. These changes
-essentially make it so that the current implementation is at least
-equal to the best alignment of the original for any arguments.
-
-The only additional optimization is in the page cross case. Branch on
-equals case was removed from the size == [4, 7] case. As well the [4,
-7] and [2, 3] case where swapped as [4, 7] is likely a more hot
-argument size.
-
-test-memcmp and test-wmemcmp are both passing.

-Subject: [PATCH] x86: Optimize memset-vec-unaligned-erms.S
-Content-type: text/plain; charset=UTF-8
-
-No bug.
-
-Optimization are
-
-1. change control flow for L(more_2x_vec) to fall through to loop and
-   jump for L(less_4x_vec) and L(less_8x_vec). This uses less code
-   size and saves jumps for length > 4x VEC_SIZE.
-
-2. For EVEX/AVX512 move L(less_vec) closer to entry.
-
-3. Avoid complex address mode for length > 2x VEC_SIZE
-
-4. Slightly better aligning code for the loop from the perspective of
-   code size and uops.
-
-5. Align targets so they make full use of their fetch block and if
-   possible cache line.
-
-6. Try and reduce total number of icache lines that will need to be
-   pulled in for a given length.
-
-7. Include "local" version of stosb target. For AVX2/EVEX/AVX512
-   jumping to the stosb target in the sse2 code section will almost
-   certainly be to a new page. The new version does increase code size
-   marginally by duplicating the target but should get better iTLB
-   behavior as a result.
-
-test-memset, test-wmemset, and test-bzero are all passing.

-Subject: [PATCH] x86: Replace sse2 instructions with avx in
- memcmp-evex-movbe.S
-Content-type: text/plain; charset=UTF-8
-
-This commit replaces two usages of SSE2 'movups' with AVX 'vmovdqu'.
-
-it could potentially be dangerous to use SSE2 if this function is ever
-called without using 'vzeroupper' beforehand. While compilers appear
-to use 'vzeroupper' before function calls if AVX2 has been used, using
-SSE2 here is more brittle. Since it is not absolutely necessary it
-should be avoided.
-
-It costs 2-extra bytes but the extra bytes should only eat into
-alignment padding.

-Subject: [PATCH] x86-64: Improve EVEX strcmp with masked load
-Content-type: text/plain; charset=UTF-8

-
-        VMOVU   (%rdi, %rdx), %YMM0
-        VMOVU   (%rsi, %rdx), %YMM1
-        /* Each bit in K0 represents a mismatch in YMM0 and YMM1.  */
-        VPCMP   $4, %YMM0, %YMM1, %k0
-        VPCMP   $0, %YMMZERO, %YMM0, %k1
-        VPCMP   $0, %YMMZERO, %YMM1, %k2
-        /* Each bit in K1 represents a NULL in YMM0 or YMM1.  */
-        kord    %k1, %k2, %k1
-        /* Each bit in K1 represents a NULL or a mismatch.  */
-        kord    %k0, %k1, %k1
-        kmovd   %k1, %ecx
-        testl   %ecx, %ecx
-        jne     L(last_vector)
-
-with
-
-        VMOVU   (%rdi, %rdx), %YMM0
-        VPTESTM %YMM0, %YMM0, %k2
-        /* Each bit cleared in K1 represents a mismatch or a null CHAR
-           in YMM0 and 32 bytes at (%rsi, %rdx).  */
-        VPCMP   $0, (%rsi, %rdx), %YMM0, %k1{%k2}
-        kmovd   %k1, %ecx
-        incl    %ecx
-        jne     L(last_vector)
-
-It makes EVEX strcmp faster than AVX2 strcmp by up to 40% on Tiger Lake
-and Ice Lake.

-From: "H.J. Lu" <hjl.tools@gmail.com>
-Date: Mon, 21 Jan 2019 11:33:52 -0800
-Subject: [PATCH] x86-64 strncmp family: Properly handle the length parameter
- [BZ# 24097]
-Content-type: text/plain; charset=UTF-8
-
-On x32, the size_t parameter may be passed in the lower 32 bits of a
-64-bit register with the non-zero upper 32 bits.  The string/memory
-functions written in assembly can only use the lower 32 bits of a
-64-bit register as length or must clear the upper 32 bits before using
-the full 64-bit register for length.
-
-This pach fixes the strncmp family for x32.  Tested on x86-64 and x32.
-On x86-64, libc.so is the same with and withou the fix.
-
-	[BZ# 24097]
-	CVE-2019-6488
-	* sysdeps/x86_64/multiarch/strcmp-avx2.S: Use RDX_LP for length.
-	* sysdeps/x86_64/multiarch/strcmp-sse42.S: Likewise.
-	* sysdeps/x86_64/strcmp.S: Likewise.
-	* sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-strncasecmp,
-	tst-size_t-strncmp and tst-size_t-wcsncmp.
-	* sysdeps/x86_64/x32/tst-size_t-strncasecmp.c: New file.
-	* sysdeps/x86_64/x32/tst-size_t-strncmp.c: Likewise.
-	* sysdeps/x86_64/x32/tst-size_t-wcsncmp.c: Likewise.

-Subject: [PATCH] x86: Double size of ERMS rep_movsb_threshold in
- dl-cacheinfo.h
-Content-type: text/plain; charset=UTF-8
-
-No bug.
-
-This patch doubles the rep_movsb_threshold when using ERMS. Based on
-benchmarks the vector copy loop, especially now that it handles 4k
-aliasing, is better for these medium ranged.
-
-On Skylake with ERMS:

-Subject: [PATCH] Add LLL_MUTEX_READ_LOCK [BZ #28537]
-Content-type: text/plain; charset=UTF-8
-
-CAS instruction is expensive.  From the x86 CPU's point of view, getting
-a cache line for writing is more expensive than reading.  See Appendix
-A.2 Spinlock in:
-
-https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/xeon-lock-scaling-analysis-paper.pdf
-
-The full compare and swap will grab the cache line exclusive and cause
-excessive cache line bouncing.
-
-Add LLL_MUTEX_READ_LOCK to do an atomic load and skip CAS in spinlock
-loop if compare may fail to reduce cache line bouncing on contended locks.

-Subject: [PATCH] x86-64 strncpy: Properly handle the length parameter [BZ#
- 24097]
-Content-type: text/plain; charset=UTF-8
-
-On x32, the size_t parameter may be passed in the lower 32 bits of a
-64-bit register with the non-zero upper 32 bits.  The string/memory
-functions written in assembly can only use the lower 32 bits of a
-64-bit register as length or must clear the upper 32 bits before using
-the full 64-bit register for length.
-
-This pach fixes strncpy for x32.  Tested on x86-64 and x32.  On x86-64,
-libc.so is the same with and withou the fix.
-
-	[BZ# 24097]
-	CVE-2019-6488
-	* sysdeps/x86_64/multiarch/strcpy-avx2.S: Use RDX_LP for length.
-	* sysdeps/x86_64/multiarch/strcpy-sse2-unaligned.S: Likewise.
-	* sysdeps/x86_64/multiarch/strcpy-ssse3.S: Likewise.
-	* sysdeps/x86_64/x32/Makefile (tests): Add tst-size_t-strncpy.

-Content-type: text/plain; charset=UTF-8
-
-No bug.
-Optimizations are twofold.
-
-1) Replace page cross and 0/1 checks with masked load instructions in
-   L(less_vec). In applications this reduces branch-misses in the
-   hot [0, 32] case.
-2) Change controlflow so that L(less_vec) case gets the fall through.
-
-Change 2) helps copies in the [0, 32] size range but comes at the cost
-of copies in the [33, 64] size range.  From profiles of GCC and
-Python3, 94%+ and 99%+ of calls are in the [0, 32] range so this
-appears to the the right tradeoff.

-Subject: [PATCH] nptl: Effectively skip CAS in spinlock loop
-Content-type: text/plain; charset=UTF-8
-
-The commit:
-"Add LLL_MUTEX_READ_LOCK [BZ #28537]"
-SHA1: d672a98a1af106bd68deb15576710cd61363f7a6
-
-introduced LLL_MUTEX_READ_LOCK, to skip CAS in spinlock loop
-if atomic load fails. But, "continue" inside of do-while loop
-does not skip the evaluation of escape expression, thus CAS
-is not skipped.
-
-Replace do-while with while and skip LLL_MUTEX_TRYLOCK if
-LLL_MUTEX_READ_LOCK fails.

-Subject: [PATCH] x86: Test wcscmp RTM in the wcsncmp overflow case [BZ #28896]
-Content-type: text/plain; charset=UTF-8
-
-In the overflow fallback strncmp-avx2-rtm and wcsncmp-avx2-rtm would
-call strcmp-avx2 and wcscmp-avx2 respectively. This would have
-not checks around vzeroupper and would trigger spurious
-aborts. This commit fixes that.
-
-test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass on
-AVX2 machines with and without RTM.

-Subject: [PATCH] x86: Fix TEST_NAME to make it a string in tst-strncmp-rtm.c
-Content-type: text/plain; charset=UTF-8
-
-Previously TEST_NAME was passing a function pointer. This didn't fail
-because of the -Wno-error flag (to allow for overflow sizes passed
-to strncmp/wcsncmp)
