From f2ccdd2700174c717dc55a0f4c3f5a91ae73ff42 Mon Sep 17 00:00:00 2001
From: Yonghong Song <yhs@fb.com>

Subject: [PATCH] [BPF] annotate DIType metadata for builtin
preseve_array_access_index()
Previously, debuginfo types are annotated to
IR builtin preserve_struct_access_index() and
preserve_union_access_index(), but not
preserve_array_access_index(). The debug info
is useful to identify the root type name which
later will be used for type comparison.
For user access without explicit type conversions,
the previous scheme works as we can ignore intermediate
compiler generated type conversions (e.g., from union types to
union members) and still generate correct access index string.
The issue comes with user explicit type conversions, e.g.,
converting an array to a structure like below:
struct t { int a; char b[40]; };
struct p { int c; int d; };
struct t *var = ...;
... __builtin_preserve_access_index(&(((struct p *)&(var->b[0]))->d)) ...
Although BPF backend can derive the type of &(var->b[0]),
explicit type annotation make checking more consistent
and less error prone.
Another benefit is for multiple dimension array handling.
For example,
struct p { int c; int d; } g[8][9][10];
... __builtin_preserve_access_index(&g[2][3][4].d) ...
It would be possible to calculate the number of "struct p"'s
before accessing its member "d" if array debug info is
available as it contains each dimension range.
This patch enables to annotate IR builtin preserve_array_access_index()
with proper debuginfo type. The unit test case and language reference
is updated as well.

(cherry picked from commit d0ea05d5eff475a27a5d3bbe4d9fd389935f9cb2)
Also added back
Value *CreatePreserveArrayAccessIndex(Value *Base, unsigned Dimension,
unsigned LastIndex);
To avoid breaking the ABI.

+llvm-strip - object stripping tool
+==================================
+
+.. program:: llvm-strip
+
+SYNOPSIS
+--------
+
+:program:`llvm-strip` [*options*] *inputs...*
+
+DESCRIPTION
+-----------
+
+:program:`llvm-strip` is a tool to strip sections and symbols from object files.
+If no other stripping or remove options are specified, :option:`--strip-all`
+will be enabled by default.
+
+The input files are modified in-place. If "-" is specified for the input file,
+the input is read from the program's standard input stream.
+
+If the input is an archive, any requested operations will be applied to each
+archive member individually.
+
+The tool is still in active development, but in most scenarios it works as a
+drop-in replacement for GNU's :program:`strip`.
+
+GENERIC AND CROSS-PLATFORM OPTIONS
+----------------------------------
+
+The following options are either agnostic of the file format, or apply to
+multiple file formats.
+
+.. option:: --disable-deterministic-archives, -U
+
+ Use real values for UIDs, GIDs and timestamps when updating archive member
+ headers.
+
+.. option:: --discard-all, -x
+
+ Remove most local symbols from the output. Different file formats may limit
+ this to a subset of the local symbols. For example, file and section symbols in
+ ELF objects will not be discarded.
+
+.. option:: --enable-deterministic-archives, -D
+
+ Enable deterministic mode when stripping archives, i.e. use 0 for archive member
+ header UIDs, GIDs and timestamp fields. On by default.
+
+.. option:: --help, -h
+
+ Print a summary of command line options.
+
+.. option:: --no-strip-all
+
+ Disable --strip-all.
+
+.. option:: -o <file>
+
+ Write output to <file>. Multiple input files cannot be used in combination
+ with -o.
+
+.. option:: --regex
+
+ If specified, symbol and section names specified by other switches are treated
+ as extended POSIX regular expression patterns.
+
+.. option:: --remove-section <section>, -R
+
+ Remove the specified section from the output. Can be specified multiple times
+ to remove multiple sections simultaneously.
+
+.. option:: --strip-all-gnu
+
+ Remove all symbols, debug sections and relocations from the output. This option
+ is equivalent to GNU :program:`strip`'s ``--strip-all`` switch.
+
+.. option:: --strip-all, -S
+
+ For ELF objects, remove from the output all symbols and non-alloc sections not
+ within segments, except for .gnu.warning sections and the section name table.
+
+ For COFF objects, remove all symbols, debug sections, and relocations from the
+ output.
+
+.. option:: --strip-debug, -g
+
+ Remove all debug sections.
+
+.. option:: --strip-sections
+
+ Remove all section headers and all sections not in segments.
+
+.. option:: --strip-symbol <symbol>, -N
+
+ Remove all symbols named ``<symbol>`` from the output. Can be specified
+ multiple times to remove multiple symbols.
+
+.. option:: --strip-unneeded
+
+ Remove all local or undefined symbols that are not required by relocations.
+
+.. option:: --version, -V
+
+ Display the version of this program.
+
+COFF-SPECIFIC OPTIONS
+---------------------
+
+The following options are implemented only for COFF objects. If used with other
+objects, :program:`llvm-strip` will either emit an error or silently ignore
+them.
+
+.. option:: --only-keep-debug
+
+ Remove the contents of non-debug sections from the output, but keep the section
+ headers.
+
+ELF-SPECIFIC OPTIONS
+--------------------
+
+The following options are implemented only for ELF objects. If used with other
+objects, :program:`llvm-strip` will either emit an error or silently ignore
+them.
+
+.. option:: --allow-broken-links
+
+ Allow llvm-strip to remove sections even if it would leave invalid section
+ references. Any invalid sh_link fields will be set to zero.
+
+.. option:: --discard-locals, -X
+
+ Remove local symbols starting with ".L" from the output.
+
+.. option:: --keep-file-symbols
+
+ Keep symbols of type `STT_FILE`, even if they would otherwise be stripped.
+
+ .. option:: --keep-section <section>
+
+ When removing sections from the output, do not remove sections named
+ ``<section>``. Can be specified multiple times to keep multiple sections.
+
+.. option:: --keep-symbol <symbol>, -K
+
+ Do not remove symbols named ``<symbol>``. Can be specified multiple times to
+ keep multiple symbols.
+
+.. option:: --preserve-dates, -p
+
+ Preserve access and modification timestamps.
+
+
+EXIT STATUS
+-----------
+
+:program:`llvm-strip` exits with a non-zero exit code if there is an error.
+Otherwise, it exits with code 0.
+

Date: Mon, 30 Sep 2019 07:46:52 +0000
Subject: [PATCH] Revert "[SCEV] add no wrap flag for SCEVAddExpr."
This reverts r366419 because the analysis performed is within the context of
the loop and it's only valid to add wrapping flags to "global" expressions if
they're always correct.

From e4e77bb8bf741f52b43b90987646f1c118914848 Mon Sep 17 00:00:00 2001
From: Jordan Rupprecht <rupprecht@google.com>
Date: Wed, 21 Aug 2019 18:00:17 +0000
Subject: [PATCH] [docs] Convert remaining command guide entries from md to
rst.
Summary:
Linking between markdown and rst files is currently not supported very well, e.g. the current llvm-addr2line docs [1] link to "llvm-symbolizer" instead of "llvm-symbolizer.html". This is weirdly broken in different ways depending on which versions of sphinx and recommonmark are being used, so workaround the bug by using rst everywhere.

-# llvm-addr2line - a drop-in replacement for addr2line
-
-## SYNOPSIS
-
-**llvm-addr2line** [*options*]
-
-## DESCRIPTION
-
-**llvm-addr2line** is an alias for the [llvm-symbolizer](llvm-symbolizer) tool
-with different defaults. The goal is to make it a drop-in replacement for
-GNU's **addr2line**.
-
-Here are some of those differences:
-
-* Defaults not to print function names. Use [-f](llvm-symbolizer-opt-f)
- to enable that.
-
-* Defaults not to demangle function names. Use [-C](llvm-symbolizer-opt-C)
- to switch the demangling on.
-
-* Defaults not to print inlined frames. Use [-i](llvm-symbolizer-opt-i)
- to show inlined frames for a source code location in an inlined function.
-
-* Uses [--output-style=GNU](llvm-symbolizer-opt-output-style) by default.
-
-## SEE ALSO
-
-Refer to [llvm-symbolizer](llvm-symbolizer) for additional information.
