2016-03-28[libprofile] Handle '\\' in __llvm_profile_recursive_mkdirSean Silva
This is implicitly needed at least by gcc-flag-compatibility.test The thing that needs it is the `\` preceding the "default.profraw" appended internally by clang when doing `-fprofile-use=`. Clang uses `\` because is uses sys::path::append which will use `\` on a Windows host. This is wrong, but I don't think there's an easy way to solve it (maybe just always using `/` since places that accept `\` also tend to accept `/`, but not the other way around). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@264665 91177308-0d34-0410-b5e6-96231b3b80d8

2016-03-02Add some minimal portability code paths for PS4.Sean Silva
Summary: Hi David, SCE folks, What is implemented in this patch is enough for the upstream libprofile to work for PGO with the PS4 game codebase I tested ("game7" for you SCE folks; this is with a standalone build of compiler-rt). The first change, which is simple, is to stub out gethostname. PS4 doesn't have a simple analog for this that doesn't bring in extra OS libraries, so for now we do not support `%h` expansion. This is consistent with internal B#136272. The second change implies future work, but is a simple change at present. PS4 does not have `getenv`, so for now we will introduce a shim. This obviously makes it impossible for many of the tests to be run since they require setting `LLVM_PROFILE_FILE=`. I see two paths forward: 1. In the tests we are already wrapping execution with `%run` and so by setting a PS4-specific expansion for `%run` we can pass the information in another way We can adapt the getenv shim as appropriate. We will need to experiment with this internally. Maggie, Phillip, Filipe? Any ideas? Maybe ping me internally since we may need to get into some PS4 vagaries. I'm thinking a fake getenv library that uses some side channel for communication. 2. Another possibility which is more verbose is to use a separate clang invocation with `-profile-generate=<filename>` to set the filename in each test. This might require redundant clang invocations though which may be undesirable for upstream. David, thoughts? Also, this is a fairly libprofile-specific workaround, so it e.g. doesn't help Filipe's ASan work. Overall, this approach sounds like a bit of a hack to me. Small detail: InstrProfilingPort.h seems like the natural place for the getenv shim, but GCDAProfiling.c needs it as well. InstrProfilingUtil.h is currently the only header common between InstrProfilingFile.c and GCDAProfiling.c. I can move the shim to InstrProfilingPort.h and add an include to GCDAProfiling.c as per your preference David.

2016-02-26[profile] Compute number of data entries correctlyVedant Kumar
Compiler-rt miscalculates the number of entries in the __llvm_prf_data section on i386 Darwin. This results in a number of test failures (which we started catching after r261344). The fix we attempted earlier is insufficient (r261683). It caused some tests to start passing again, but that hid the fact that we drop some data entries. This patch should fix the real problem. It fixes the way we compute DataSize by taking into account the way the Darwin linker lays out __llvm_prf_data.

2016-02-23[profile] Fix iteration over profile data entriesVedant Kumar
Fix a crash when gathering value profile data on i386 Darwin. The Darwin linker shrinks sections containing aligned structures when padding is not explicitly added to the end of the structure. When iterating over these structures, be sure to not walk past the end of the section. No tests added, since running `ninja check-profile` on i386 Darwin is enough to reproduce the original crash. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@261683 91177308-0d34-0410-b5e6-96231b3b80d8
