Here's the warnings and how they were fixed: - InstrProfilingUtil.c(110): warning C4013: '_open_osfhandle' undefined; assuming extern returning int Include io.h to get the prototype. - warning C4005: 'FILE_MAP_EXECUTE': macro redefinition Stop trying to support pre-XP versions of Windows, don't attempt to define this macro. - InstrProfilingWriter.c(271): warning C4221: nonstandard extension used: 'Data': cannot be initialized using address of automatic variable 'Header' - InstrProfilingWriter.c(275): warning C4221: nonstandard extension used: 'Data': cannot be initialized using address of automatic variable 'Zeroes' Turn this warning off. This is definitely legal in C++, all compilers accept it, and I only have room for half of one language standard in my brain. - InstrProfilingValue.c(320): warning C4113: 'uint32_t (__cdecl *)()' differs in parameter lists from 'uint32_t (__cdecl *)(void)' Fix this with an explicit (void) in the prototype. - InstrProfilingMerge.c.obj : warning LNK4006: _VPMergeHook already defined in InstrProfilingMergeFile.c.obj; second definition ignored Last remaining warning. This is from linking a selectany definition with a strong definition. We need to sort out weak symbols in compiler-rt in general, though. llvm-svn: 273026
