Bob Wilson 16522c01dc Remove "-Wl,-seg1addr -Wl,0xE0000000" from link options. 
Specifying the load address for Darwin i386 dylibs was a performance
optimization for dyld that is not relevant for x86_64 or arm. We can just
remove this now.

Nick Lewycky d50cff6dc9 Remove GCDAProfiling.c. This copy is old, the copy in compiler-rt is newer and 
is the one that should be used.

Nick Lewycky 6fd43e4071 In GCC 4.7, function names are now forbidden from .gcda files. Support this by 
passing a null pointer to the function name in to GCDAProfiling, and add another
switch onto GCOVProfiling.

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.

(read-only or something), then exit gracefully.

Nick Lewycky 892e9934ba Create the parent directories to place the .gcda files in if they don't exist. 
That's kinda weird because the .gcno files are supposed to already be there,
but libgcov does this and somehow Google has managed to depend on it.

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).
