No linker behavior difference when module_ctor is not in a comdat.Mach-O: module_ctor gets `N_NO_DEAD_STRIP`. No linker behavior differencebecause module_ctor is already referenced by a `S_MOD_INIT_FUNC_POINTERS`section (GC root).PE/COFF: no-op. SanitizerCoverage already appends module_ctor to `llvm.used`.Other sanitizers: llvm.used for local linkage is not implemented in`TargetLoweringObjectFileCOFF::emitLinkerDirectives` (once implemented orswitched to a non-local linkage, COFF can use module_ctor in comdat (i.e.generalize ELF-specific rL301586)).There is no object file size difference.Reviewed By: vitalybukaDifferential Revision: https://reviews.llvm.org/D106246 List of files: /llvm-project/llvm/test/Instrumentation/HeapProfiler/basic.ll Wed, 21 Jul 2021 21:03:26 +0000 Fangrui Song <i@maskray.me> http://src.rcs.uwaterloo.ca:8080/source/history/llvm-project/llvm/test/Instrumentation/HeapProfiler/basic.ll#226d80ebe20e2d796af6c1bc43d9fbdfbb9d4a07 [MemProf] Rename HeapProfiler to MemProfiler for consistencyThis is consistent with the clang option added in7ed8124d46f94601d5f1364becee9cee8538265e, and the comments on theruntime patch in D87120.Differential Revision: https://reviews.llvm.org/D87622 List of files: /llvm-project/llvm/test/Instrumentation/HeapProfiler/basic.ll Mon, 14 Sep 2020 16:12:13 +0000 Teresa Johnson <tejohnson@google.com> http://src.rcs.uwaterloo.ca:8080/source/history/llvm-project/llvm/test/Instrumentation/HeapProfiler/basic.ll#7ed8124d46f94601d5f1364becee9cee8538265e [HeapProf] Clang and LLVM support for heap profiling instrumentationSee RFC for background:http://lists.llvm.org/pipermail/llvm-dev/2020-June/142744.htmlNote that the runtime changes will be sent separately (hopefully thisweek, need to add some tests).This patch includes the LLVM pass to instrument memory accesses witheither inline sequences to increment the access count in the shadowlocation, or alternatively to call into the runtime. It also changescalls to memset/memcpy/memmove to the equivalent runtime version.The pass is modeled on the address sanitizer pass.The clang changes add the driver option to invoke the new pass, and tolink with the upcoming heap profiling runtime libraries.Currently there is no attempt to optimize the instrumentation, e.g. toaggregate updates to the same memory allocation. That will beimplemented as follow on work.Differential Revision: https://reviews.llvm.org/D85948 List of files: /llvm-project/llvm/test/Instrumentation/HeapProfiler/basic.ll Thu, 13 Aug 2020 23:29:38 +0000 Teresa Johnson <tejohnson@google.com>
