NAKAMURA Takumi d1cc9db3d6 libprofile/CommonProfiling.c: Fix according to C89.
llvm-svn: 167272
2012-11-02 01:32:02 +00:00
Manman Ren 7dcadc6dbe PGO: allows the profile data file name to be specified by the LLVMPROF_OUTPUT
environment variable.

This allows parallel make for profiling code, without it there are file
collisions as each parallel run uses the default file name.

There is already code in the runtime library to specify the output file name
via the command line, but this only works for programs which already process
argc/argv.  This patch builds on that support.

Patch by Alastair Murray.

Manman Ren 32a71b9659 Profile: move a single enum out of ProfileInfoTypes.h into a new
ProfileDataTypes.h header.

With this patch the old and new profiling code can exist side-by-side. The new
profiling code will be submitted soon and it only supports insert-edge-profiling
for now and will not depend on ProfileInfo.

Bill Wendling 79f9bc04ab Try to use the CWD if the path to the GCDA output is not available (e.g., the
executable has been moved to another machine). If that's not available
(read-only or something), then exit gracefully.

Nick Lewycky 61aed87a49 Rename profile_rt.so to libprofile_rt.so under configure+make (it already was
under cmake).

Add libprofile_rt.a so that we can tell clang to link against it in --coverage
mode. Also turn it on by default in cmake builds.

Oscar, this touches a change you made for EXCLUDE_FROM_ALL support -- I think
I've done the right thing, but please let me know (or fix and commit) if not!

Nick Lewycky 6aa79492a5 Only read *predecessor once so as to fix a theoretical issue where it changes
between two reads (threading).

Fix an off-by-one in the indirect counter table that I meant to revert after an
earlier experiment. Whoops!

Implement GCOV_PREFIX. Doesn't handle GCOV_PREFIX_STRIP yet.

Fix an off-by-one in string emission. Extra whoops!

Tolerate DISubprograms that have null Function*'s attached to them. I don't yet
understand what this means, but it happens when you have a global static with
a non-trivial constructor/destructor.

Fix a crash on switch statements with a single successor (default-only).

Nick Lewycky c58d293a6f Rename everything to follow LLVM style ... I think.
Add support for switch and indirectbr edges. This works by densely numbering
all blocks which have such terminators, and then separately numbering the
possible successors. The predecessors write down a number, the successor knows
its own number (as a ConstantInt) and sends that and the pointer to the number
the predecessor wrote down to the runtime, who looks up the counter in a
per-function table.

Coverage data should now be functional, but I haven't tested it on anything
other than my 2-file synthetic test program for coverage.
