Also fixed an issue with concatenationof default and test specified options (missing separator).Differential Revision: https://reviews.llvm.org/D113617 List of files: /llvm-project-15.0.7/compiler-rt/test/memprof/TestCases/malloc-size-too-big.cpp Wed, 10 Nov 2021 22:37:15 +0000 Snehasish Kumar <snehasishk@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/memprof/TestCases/malloc-size-too-big.cpp#0949f96d [MemProf] Pass down memory profile name with optional path from clangSimilar to -fprofile-generate=, add -fmemory-profile= which takes adirectory path. This is passed down to LLVM via a new module flagmetadata. LLVM in turn provides this name to the runtime via the new__memprof_profile_filename variable.Additionally, always pass a default filename (in $cwd if a directoryname is not specified vi the = form of the option). This is alsoconsistent with the behavior of the PGO instrumentation. Since thememory profiles will generally be fairly large, it doesn't make sense todump them to stderr. Also, importantly, the memory profiles willeventually be dumped in a compact binary format, which is another reasonwhy it does not make sense to send these to stderr by default.Change the existing memprof tests to specify log_path=stderr when thatwas being relied on.Depends on D89086.Differential Revision: https://reviews.llvm.org/D89087 List of files: /llvm-project-15.0.7/compiler-rt/test/memprof/TestCases/malloc-size-too-big.cpp Tue, 29 Sep 2020 22:53:41 +0000 Teresa Johnson <tejohnson@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/memprof/TestCases/malloc-size-too-big.cpp#3d4bba30 [MemProf] Memory profiling runtime supportSee RFC for background:http://lists.llvm.org/pipermail/llvm-dev/2020-June/142744.htmlFollow on companion to the clang/llvm instrumentation support in D85948and committed earlier.This patch adds the compiler-rt runtime support for the memoryprofiling.Note that much of this support was cloned from asan (and then greatlysimplified and renamed). For example the interactions with thesanitizer_common allocators, error handling, interception, etc.The bulk of the memory profiling specific code can be found in theMemInfoBlock, MemInfoBlockCache, and related classes defined and usedin memprof_allocator.cpp.For now, the memory profile is dumped to text (stderr by default, buthonors the sanitizer_common log_path flag). It is dumped in either adefault verbose format, or an optional terse format.This patch also adds a set of tests for the core functionality.Differential Revision: https://reviews.llvm.org/D87120 List of files: /llvm-project-15.0.7/compiler-rt/test/memprof/TestCases/malloc-size-too-big.cpp Thu, 03 Sep 2020 22:21:20 +0000 Teresa Johnson <tejohnson@google.com>
