2017-12-14[profile] Port the runtime to Solaris (retry)Vedant Kumar
This includes a few nice bits of refactoring (e.g splitting out the exclusive locking code into a common utility). Hopefully the Windows support is fixed now. Patch by Rainer Orth!

2017-08-31Revert r312240Alex Lorenz
The buildbots have shown that -Wstrict-prototypes behaves differently in GCC and Clang so we should keep it disabled until Clang follows GCC's behaviour git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@312246 91177308-0d34-0410-b5e6-96231b3b80d8
2017-08-31Build LLVM with -Wstrict-prototypes enabledAlex Lorenz
Clang 5 supports -Wstrict-prototypes. We should use it to catch any C declarations that declare a non-prototype function. rdar://33705313 Differential Revision: https://reviews.llvm.org/D36669 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@312240 91177308-0d34-0410-b5e6-96231b3b80d8

2017-06-27[PGO] Refactor file/buffer writer callback interfaces /NFCXinliang David Li
Introduces a 'owner' struct to include the overridable write method and the write context in C.

2016-05-14[profile] Eliminate dynamic memory allocation for vp writingXinliang David Li
This is part-3 of the effort to eliminate dependency on libc allocator in instr profiler runtime. With this change, the profile dumper is completely free of malloc/calloc. Value profile instr API implementation is the only remaining piece with calloc dependency. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@269576 91177308-0d34-0410-b5e6-96231b3b80d8
2016-05-13[profile] Eliminate dynamic memory allocation for buffered writerXinliang David Li
With this change, dynamic memory allocation is only used for testing purpose. This change is one of the many steps to make instrument profiler dynamic allocation free. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@269453 91177308-0d34-0410-b5e6-96231b3b80d8

2016-05-07Revert "[profile] Simplify value profile writing"Renato Golin
This reverts commit r268840, as it breaks Thumb2 self-hosting. There is something unstable in the profiling for Thumb2 that needs to be sorted out before we continue implementing these changes to the profiler. See PR27667. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@268864 91177308-0d34-0410-b5e6-96231b3b80d8
2016-05-07[profile] Simplify value profile writingXinliang David Li
With this patch, value data are longer pre-collected before writing. The code is simplified and requires less heap space for dumping. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@268840 91177308-0d34-0410-b5e6-96231b3b80d8

2015-12-29[PGO]: Refactor VP data writerXinliang David Li
Extract the buffered filer writer code used by value profile writer and turn it into common/sharable buffered fileIO interfaces. Added a test case for the buffered file writer and rewrite the VP dumping using the new APIs. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@256604 91177308-0d34-0410-b5e6-96231b3b80d8
2015-12-29[PGO]: Do not update Data->Value field during profile write.Xinliang David Li
The profile reader no longer depends on this field to be updated and point to owning func's vp data. The VP data also no longer needs to be allocated in a contiguous memory space.

2015-11-21[PGO] Implement a more robust/readable Writer callback interfaceXinliang David Li
(patch suggested by silvas) With this patch, the IO information is wrapped in struct ProfDataIOVec, and interface of writerCallback takes a vector of IOVec and a pointer to writer context pointer.

2014-12-09profile: Add low level versions of profile buffer functionsJustin Bogner
On Darwin, compiler_rt uses magic linker symbols to find the profile counters in the __DATA segment. This is a reasonable method for normal, hosted, userspace programs. However programs with custom memory layouts, such as the kernel, will need to tell compiler_rt explicitly where to find these sections. Patch by Lawrence D'Anna. Thanks! git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@223840 91177308-0d34-0410-b5e6-96231b3b80d8
