a25c1fd8bb [XRay] Add llvm-xray as a dependency to test/CMakeLists.txt
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@285166 91177308-0d34-0410-b5e6-96231b3b80d8

6af7eec625 Add an llvm-opt-report tool to generate basic source-annotated optimization summaries
LLVM now has the ability to record information from optimization remarks in a
machine-consumable YAML file for later analysis. This can be enabled in opt
(see r282539), and D25225 adds a Clang flag to do the same. This patch adds
llvm-opt-report, a tool to generate basic optimization "listing" files
(annotated sources with information about what optimizations were performed)
from one of these YAML inputs.

D19678 proposed to add this capability directly to Clang, but this more-general
YAML-based infrastructure was the direction we decided upon in that review
thread.

For this optimization report, I focused on making the output as succinct as
possible while providing information on inlining and loop transformations. The
goal here is that the source code should still be easily readable in the
report. My primary inspiration here is the reports generated by Cray's tools
(http://docs.cray.com/books/S-2496-4101/html-S-2496-4101/z1112823641oswald.html).
These reports are highly regarded within the HPC community. Intel's compiler,
for example, also has an optimization-report capability
(https://software.intel.com/sites/default/files/managed/55/b1/new-compiler-optimization-reports.pdf).

  $ cat /tmp/v.c
  void bar();
  void foo() { bar(); }

  void Test(int *res, int *c, int *d, int *p, int n) {
    int i;

  #pragma clang loop vectorize(assume_safety)
    for (i = 0; i < 1600; i++) {
      res[i] = (p[i] == 0) ? res[i] : res[i] + d[i];
    }

    for (i = 0; i < 16; i++) {
      res[i] = (p[i] == 0) ? res[i] : res[i] + d[i];
    }

    foo();

    foo(); bar(); foo();
  }

D25225 adds -fsave-optimization-record (and
-fsave-optimization-record=filename), and this would be used as follows:

  $ clang -O3 -o /tmp/v.o -c /tmp/v.c -fsave-optimization-record
  $ llvm-opt-report /tmp/v.yaml > /tmp/v.lst
  $ cat /tmp/v.lst

  < /tmp/v.c
   2          | void bar();
   3          | void foo() { bar(); }
   4          |
   5          | void Test(int *res, int *c, int *d, int *p, int n) {
   6          |   int i;
   7          |
   8          | #pragma clang loop vectorize(assume_safety)
   9     V4,2 |   for (i = 0; i < 1600; i++) {
  10          |     res[i] = (p[i] == 0) ? res[i] : res[i] + d[i];
  11          |   }
  12          |
  13  U16     |   for (i = 0; i < 16; i++) {
  14          |     res[i] = (p[i] == 0) ? res[i] : res[i] + d[i];
  15          |   }
  16          |
  17 I        |   foo();
  18          |
  19          |   foo(); bar(); foo();
     I        |   ^
     I        |                 ^
  20          | }

Each source line gets a prefix giving the line number, and a few columns for
important optimizations: inlining, loop unrolling and loop vectorization. An
'I' is printed next to a line where a function was inlined, a 'U' next to an
unrolled loop, and 'V' next to a vectorized loop. These are printed on the
relevant code line when that seems unambiguous, or on subsequent lines when
multiple potential options exist (messages, both positive and negative, from
the same optimization with different column numbers are taken to indicate
potential ambiguity). When on subsequent lines, a '^' is output in the relevant
column.

Annotated source for all relevant input files are put into the listing file
(each starting with '<' and then the file name).

You can disable having the unrolling/vectorization factors appear by using the
-s flag.

ec44cfdaf0 Add an c++ itanium demangler to llvm.
This adds a copy of the demangler in libcxxabi.

The code also has no dependencies on anything else in LLVM. To enforce
that I added it as another library. That way a BUILD_SHARED_LIBS will
fail if anyone adds an use of StringRef for example.

The no llvm dependency combined with the fact that this has to build
on linux, OS X and Windows required a few changes to the code. In
particular:

    No constexpr.
    No alignas

On OS X at least this library has only one global symbol:
__ZN4llvm16itanium_demangleEPKcPcPmPi

My current plan is:

    Commit something like this
    Change lld to use it
    Change lldb to use it as the fallback

    Add a few #ifdefs so that exactly the same file can be used in
    libcxxabi to export abi::__cxa_demangle.

Once the fast demangler in lldb can handle any names this
implementation can be replaced with it and we will have the one true
demangler.

2d320e58a9 Restore "Resolution-based LTO API."
This restores commit r278330, with fixes for a few bot failures:
- Fix a late change I had made to the save temps output file that I
  missed due to existing files sitting on my disk
- Fix a bunch of Windows bot failures with "ambiguous call to overloaded
  function" due to confusion between llvm::make_unique vs
  std::make_unique (preface the new make_unique calls with "llvm::")
- Attempt to fix a modules bot failure by adding a missing include
  to LTO/Config.h.

Original change:

Resolution-based LTO API.

Summary:
This introduces a resolution-based LTO API. The main advantage of this API over
existing APIs is that it allows the linker to supply a resolution for each
symbol in each object, rather than the combined object as a whole. This will
become increasingly important for use cases such as ThinLTO which require us
to process symbol resolutions in a more complicated way than just adjusting
linkage.

df57369269 [cmake] Fix builds with LLVM_ENABLE_PIC=0
Summary:
When this flag is specified, the target llvm-lto is not built, but is still
used as a dependency of the test targets. cmake 2.8 silently ignored this
situation, but with cmake_minimum_required(3.4) it becomes an error. Fix this
by avoiding the inclusion of the target as a dependency.

c0ffe0f061 test: Fix the dependencies for the check-llvm-* targets
In r233009 we gained specific check-llvm-* build targets for invoking
specific parts of the test suite, but they were copying the
dependencies for check-all, rather than just listing the dependencies
for check-llvm.

This moves the creation of these targets next to the check-llvm
target, and uses that target's configuration rather than the check-all
config.

31e081ed96 Initial dsymutil tool commit.
The goal of this tool is to replicate Darwin's dsymutil functionality
based on LLVM. dsymutil is a DWARF linker. Darwin's linker (ld64) does
not link the debug information, it leaves it in the object files in
relocatable form, but embbeds a `debug map` into the executable that
describes where to find the debug information and how to relocate it.
When releasing/archiving a binary, dsymutil is called to link all the DWARF
information into a `dsym bundle` that can distributed/stored along with
the binary.

With this commit, the LLVM based dsymutil is just able to parse the STABS
debug maps embedded by ld64 in linked binaries (and not all of them, for
example archives aren't supported yet).

Note that the tool directory is called dsymutil, but the executable is
currently called llvm-dsymutil. This discrepancy will disappear once the
tool will be feature complete. At this point the executable will be renamed
to dsymutil, but until then you do not want it to override the system one.

bdc3a5b99a Add llvm-go tool.
This tool lets us build LLVM components within the tree by setting up a
$GOPATH that resembles a tree fetched in the normal way with "go get".

It is intended that components such as the Go frontend will be built in-tree
using this tool.

2602b66b91 Move -verify-use-list-order into llvm-uselistorder
Ugh.  Turns out not even transformation passes link in how to read IR.
I sincerely believe the buildbots will finally agree with my system
after this though.  (I don't really understand why all of this has been
working on my system, but not on all the buildbots.)

Create a new tool called llvm-uselistorder to use for verifying use-list
order.  For now, just dump everything from the (now defunct)
-verify-use-list-order pass into the tool.

This might be a better way to test use-list order anyway.

Part of PR5680.

51a4c9439c Opportunistically fix the builders
A builder complained that it couldn't find llvm-vtabledump, this is
probably because it wasn't a dependency of the 'test' target.

dce55ec575 OK, NAKAMURA Takumi beat me to this change. So backing out my addition of
llvm-size to the list so it only has one.  Sorry for the noise.

d8d50e7546 David Blaikie pointed out that the test added in r209158 fails in the
check-llvm target under CMake.  And the test/CMakeFiles.txt needs to
have llvm-size added to the list.

ddc5a010a4 PGO: llvm-profdata: tool for merging profiles
Introducing llvm-profdata, a tool for merging profile data generated by
PGO instrumentation in clang.

- The name indicates a file extension of <name>.profdata.  Eventually
  profile data output by clang should be changed to that extension.

- llvm-profdata merges two profiles.  However, the name is more general,
  since it will likely pick up more tasks (such as summarizing a single
  profile).

- llvm-profdata parses the current text-based format, but will be
  updated once we settle on a binary format.
