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!

2017-06-27[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. This allows easy introdution of new member API to help reduce profile merge time in the follow up patch. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@306432 91177308-0d34-0410-b5e6-96231b3b80d8

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

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.

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.
