NAKAMURA Takumi d1cc9db3d6 libprofile/CommonProfiling.c: Fix according to C89.
llvm-svn: 167272

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.

Francois Pichet dbad1d1599 Unbreak the MSVC build:
- unistd.h doesn't exist with MSVC
  - inline must be __inline in Microsoft C
  - atexit cannot take a function declared as void f(), must be void f(void).

Andrew Trick 24f5ff0f23 Implementation of path profiling.
Modified patch by Adam Preuss.

This builds on the existing framework for block tracing, edge profiling and optimal edge profiling.
See -help-hidden for new flags.
For documentation, see the technical report "Implementation of Path Profiling..." in llvm.org/pubs.

Reid Spencer 4b8067f37b Undo removal of the runtime libraries. While this may have been a bit
premature, these libraries will be going away for the 2.0 release. Other
arrangements for profiling, gc, etc. should be made in the next few months.

Reid Spencer 3f97d03f86 In LLVM 2.0 we won't use the runtime libraries as llvm-gcc3 support will
be dropped. This patch pertains to removing the runtime directory from LLVM.

Chris Lattner 881d01f30c Make sure to copy the null terminator at the end of the argv list. Some
programs use it instead of argc.
