2014-03-19PGO: Splitting implementation files; no functionality changeDuncan P. N. Exon Smith
Split implementation files along a uses-libc/shouldn't-use-libc boundary. - InstrProfiling.h is a shared header. - InstrProfiling.c provides an API to extract profiling data from the runtime, but avoids the use of libc. Currently this is a lie: __llvm_pgo_write_buffer() uses `FILE*` and related functions. It will be updated soon to write to a `char*` buffer instead. - InstrProfilingExtras.c provides a more convenient API for interfacing with the profiling runtime, but has logic that does (and will continue to) use libc. <rdar://problem/15943240> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@204268 91177308-0d34-0410-b5e6-96231b3b80d8

2014-03-17PGO: Statically generate data structuresDuncan P. N. Exon Smith
In instrumentation-based profiling, we need a set of data structures to represent the counters. Previously, these were built up during static initialization. Now, they're shoved into a specially-named section so that they show up as an array. As a consequence of the reorganizing symbols, instrumentation data structures for linkonce functions are now correctly coalesced. This is the first step in a larger project to minimize runtime overhead and dependencies in instrumentation-based profilng. The larger picture includes removing all initialization overhead and making the dependency on libc optional. <rdar://problem/15943240> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@204079 91177308-0d34-0410-b5e6-96231b3b80d8

2014-03-17tsan: yet another attempt to fix pthread_cond interceptorsDmitry Vyukov
Make behavior introduced in r202820 conditional (under legacy_pthread_cond flag). The new issue that we've hit with the satellite pthread_cond_t struct is that pthread_condattr_getpshared does not work (satellite data is not shared between processes). The idea is that most processes do not use pthread 2.2.5. The rare ones that use (2.2.5 is dated by 2002) must specify legacy_pthread_cond=1 on their own risk. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@204032 91177308-0d34-0410-b5e6-96231b3b80d8
