 Subject: [PATCH 01/17] basic_string::reserve(n) semantics are not available in
 DTS
 Various tests were added upstream 2020-08-06 as part of:
  "libstdc++: Implement P0966 std::string::reserve should not shrink"
  https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=140cf935cd118f7208b7c3826a8b9d50936242f0
 std::string and std::wstring are instantiated in the system libstdc++.so
 via explicit instantiation definitions, so the new basic_string::reserve(n)
 semantics are not available in DTS.
 Update/disable the pertinent parts of the tests to reflect the behavior
 when run against the system libstdc++.so.

 Subject: [PATCH 04/17] operator>>(istream&, char(&)[N]) eofbit fixes are not
 available in DTS
 The upstream commit on 2020-08--6:
  Do not set eofbit eagerly in operator>>(istream&, char(&)[N])
    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=4e39f563c0cd25401f689c2093cb8c13692156ef
 altered the behaviour of std::istream symbols defined in libstdc++.so,
 but with DTS you get the old definitions from the system libstdc++.so
 Hence this patch tweaks the new tests to avoid failing when run against
 the system libstdc++.so

 Subject: [PATCH 05/17] Disable tests for PR libstdc++/79820 and PR
 libstdc++/81751 under DTS
 Upstream commit 2017-08-09
  PR libstdc++/81751 don't call fflush(NULL)
    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=04d07b61cb80fd97e98eb39451ff6a8675a63d90
 added these test cases as part of verifying the behavior of sys_open (that
 it resets errno and doesn't call fflush on NULL).
 These symbols are in the system stdlib when run from DTS and thus aren't
 fixed by the above change:
 1521: 000000000007c430    104 FUNC    GLOBAL DEFAULT       12 std::__basic_file<char>::sys_open(int, std::_Ios_Openmode)@@GLIBCXX_3.4
 2895: 000000000007c730     95 FUNC    GLOBAL DEFAULT       12 std::__basic_file<char>::sys_open(_IO_FILE*, std::_Ios_Openmode)@@GLIBCXX_3.4
 This patch disables the non-fixed assertions.

 Subject: [PATCH 06/17] Don't assume has_facet<codecvt_c16> when run against
 system libstdc++
 Upstream commit 2019-02-19:
  P0482R5 char8_t: Standard library support
    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=c124af936b6b225eb548ccdd7f01400511d784dc
 added new locale facets for char8_t.
 has_facet<codecvt_c16> returns false, as it is using the std::locale the system libstdc++:
 $ eu-readelf -s char16_t-char8_t.exe |c++filt |grep UNDEF|grep locale
    3: 0000000000000000      0 FUNC    GLOBAL DEFAULT    UNDEF std::locale::classic()@GLIBCXX_3.4 (2)

 Hence this patch tweaks tests so that they bail out if run against an older std::locale.

 Looks like plugin.exp is building the test plugins against the
 freshly-built libstdc++, and then trying to dynamically load them
 against the system libstdc++.
 This patch forces the use of -std=c++11 when building these test plugins,
 to sidestep the problem.

 Subject: [PATCH 09/17] Fix 22_locale/locale/cons/unicode.cc when run under DTS
 Various has_facet calls return false in DTS, as DTS is using the
 std::locale from the system libstdc++.
 Hence this patch tweaks tests to remove the VERIFY from the result of
 the call, so that they do not fail if run against an older
 std::locale.
 These VERIFY tests were added upstream 2015-01-16 in
  https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=bb93f35da1612940266f5d159b6cc5a3e54fca14

 27_io/basic_filebuf/close/81256.cc was added upstream 2018-05-14 in

    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=e77497ab777d3dfa19224648d658220807ab7419
 When run under DTS,
  std::basic_filebuf<wchar_t, std::char_traits<wchar_t> >::close
 comes from the system libstdc++, and hence the test fails.

 Subject: [PATCH 11/17] Add dts.exp and use it to fix
 22_locale/messages/13631.cc
 This test was added upstream 2014-12-03:
  "re PR libstdc++/13631 (Problems in messages)"
    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=d31008d7a0d53b431f176aad8dda5498de823122
 as part of a fix that is present in the system libstdc++.so in
 GCC 5 onwards.
 When run in DTS against such a system library, this test will fail.
 This patch introduces a dts.exp which detects the version of the
 underlying system libstdc++.so and exposes it to tests via
 -D__CXXSTDLIB_SO_VERSION__=, so that we can ifdef specific tests
 away, conditionally on the base GCC.

 Subject: [PATCH 16/17] Conditionalize test for hashtable bucket sizes on
 __LIBSTDCXX_SO_VERSION >= 11
 These tests were added upstream 2020-01-20 as part of:
  libstdc++: Do not over-size hashtable buckets on range insertion
    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=6dcf042368012e2d7ce1626ee5d378bf3ad0ccfc
 but fail when run in DTS against a system libstdc++.so from an older GCC.
 In particular, _M_insert_unique_node from the header is using the older
 implementation of
  std::__detail::_Prime_rehash_policy::_M_need_rehash
 from the dynamic library.

 commit 14c7757e9b751781360737f53b71f851fc356d3d
 Author: Jeff Law <jeffreyalaw@gmail.com>

    Avoid overly-greedy match in dejagnu regexp.
    Occasionally I've been seeing failures with the multi-line diagnostics.  It's never been clear what's causing the spurious failures, though I have long suspected a greedy regexp match.
    It happened again yesterday with a local change that in no way should affect diagnostics, so I finally went searching and found that sure enough the multi-line diagnostics had a ".*" in their regexp.  According to the comments, the .* is primarily to catch any dg directives that may appear -- ie it should eat to EOL, but not multiple lines.  But a .* can indeed match a newline and cause it to eat multiple lines.
    The fix is simple.  [^\r\n]* will eat to EOL, but not further.
    Regression tested on x86_64 and on our internal target.
    gcc/testsuite
            * lib/multiline.exp (_build_multiline_regex): Use a better
            regexp than .* to match up to EOL.

 libgcc: Honor LDFLAGS_FOR_TARGET when linking libgcc_s
 When building gcc with some specific LDFLAGS_FOR_TARGET, e.g.
 LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now
 those flags propagate info linking of target shared libraries,
 e.g. lib{ubsan,tsan,stdc++,quadmath,objc,lsan,itm,gphobos,gdruntime,gomp,go,gfortran,atomic,asan}.so.*
 but there is one important exception, libgcc_s.so.* linking ignores it.
 The following patch fixes that.
 Bootstrapped/regtested on x86_64-linux with LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now
 and verified that libgcc_s.so.* is BIND_NOW when it previously wasn't, and
 without any LDFLAGS_FOR_TARGET on x86_64-linux and i686-linux.
 There on x86_64-linux I've verified that the libgcc_s.so.1 linking command
 line for -m64 is identical except for whitespace to one without the patch,
 and for -m32 multilib $(LDFLAGS) actually do supply there an extra -m32
 that also repeats later in the @multilib_flags@, which should be harmless.
 2021-08-04  Jakub Jelinek  <jakub@redhat.com>
 	* config/t-slibgcc (SHLIB_LINK): Add $(LDFLAGS).
 	* config/t-slibgcc-darwin (SHLIB_LINK): Likewise.
 	* config/t-slibgcc-vms (SHLIB_LINK): Likewise.

 c++: Optimize constinit thread_local vars [PR101786]
 The paper that introduced constinit mentioned in rationale that constinit
 can be used on externs as well and that it can be used to avoid the
 thread_local initialization wrappers, because the standard requires that
 if constinit is present on any declaration, it is also present on the
 initialization declaration, even if it is in some other TU etc.
 There is a small problem though, we use the tls wrappers not just if
 the thread_local variable needs dynamic initialization, but also when
 it has static initialization, but non-trivial destructor, as the
 "dynamic initialization" in that case needs to register the destructor.
 So, the following patch optimizes constinit thread_local vars only
 if we can prove they will not have non-trivial destructors.  That includes
 the case where we have incomplete type where we don't know and need to
 conservatively assume the type will have non-trivial destructor at the
 initializing declaration side.

 libcpp: Fix up #__VA_OPT__ handling [PR103415]
 stringify_arg uses pfile->u_buff to create the string literal.
 Unfortunately, paste_tokens -> _cpp_lex_direct -> lex_number -> _cpp_unaligned_alloc
 can in some cases use pfile->u_buff too, which results in losing everything
 prepared for the string literal until the token pasting.
 The following patch fixes that by not calling paste_token during the
 construction of the string literal, but doing that before.  All the tokens
 we are processing have been pushed into a token buffer using
 tokens_buff_add_token so it is fine if we paste some of them in that buffer
 (successful pasting creates a new token in that buffer), move following
 tokens if any to make it contiguous, pop (throw away) the extra tokens at
 the end and then do stringify_arg.
 Also, paste_tokens now copies over PREV_WHITE and PREV_FALLTHROUGH flags
 from the original lhs token to the replacement token.  Copying that way
 the PREV_WHITE flag is needed for the #__VA_OPT__ handling and copying
 over PREV_FALLTHROUGH fixes the new Wimplicit-fallthrough-38.c test.

 Subject: [PATCH 1/3] x86: Update -mtune=tremont
 Initial -mtune=tremont update
 1. Use Haswell scheduling model.
 2. Assume that stack engine allows to execute push&pop instructions in
 parall.
 3. Prepare for scheduling pass as -mtune=generic.
 4. Use the same issue rate as -mtune=generic.
 5. Enable partial_reg_dependency.
 6. Disable accumulate_outgoing_args
 7. Enable use_leave
 8. Enable push_memory
 9. Disable four_jump_limit
 10. Disable opt_agu
 11. Disable avoid_lea_for_addr
 12. Disable avoid_mem_opnd_for_cmove
 13. Enable misaligned_move_string_pro_epilogues
 14. Enable use_cltd
 16. Enable avoid_false_dep_for_bmi
 17. Enable avoid_mfence
 18. Disable expand_abs
 19. Enable sse_typeless_stores
 20. Enable sse_load0_by_pxor
 21. Disable split_mem_opnd_for_fp_converts
 22. Disable slow_pshufb
 23. Enable partial_reg_dependency

 Subject: [PATCH 2/3] x86: Update memcpy/memset inline strategies for
 -mtune=tremont
 Simply memcpy and memset inline strategies to avoid branches for
 -mtune=tremont:
 1. Create Tremont cost model from generic cost model.
 2. With MOVE_RATIO and CLEAR_RATIO == 17, GCC will use integer/vector
   load and store for up to 16 * 16 (256) bytes when the data size is
   fixed and known.
 3. Inline only if data size is known to be <= 256.
   a. Use "rep movsb/stosb" with simple code sequence if the data size
      is a constant.
   b. Use loop if data size is not a constant.
 4. Use memcpy/memset libray function if data size is unknown or > 256.
 	* config/i386/i386-options.c (processor_cost_table): Use
 	tremont_cost for Tremont.
 	* config/i386/x86-tune-costs.h (tremont_memcpy): New.
 	(tremont_memset): Likewise.
 	(tremont_cost): Likewise.
 	* config/i386/x86-tune.def (X86_TUNE_PREFER_KNOWN_REP_MOVSB_STOSB):
 	Enable for Tremont.
