The effect of thisis twofold:* If IR that contains *neither* explicit ptr nor %T* types is passed to tools, we will now use opaque pointer mode, unless -opaque-pointers=0 has been explicitly passed.* Users of LLVM as a library will now default to opaque pointers. It is possible to opt-out by calling setOpaquePointers(false) on LLVMContext.A cmake option to toggle this default will not be provided. Frontendsor other tools that want to (temporarily) keep using typed pointersshould disable opaque pointers via LLVMContext.Differential Revision: https://reviews.llvm.org/D126689 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/SanitizerCoverage/inline-8bit-counters.ll Tue, 31 May 2022 09:58:35 +0000 Nikita Popov <npopov@redhat.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Instrumentation/SanitizerCoverage/inline-8bit-counters.ll#86d1a0b3 [test] Remove some legacy PM tests in llvm/test/Instrumentation List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/SanitizerCoverage/inline-8bit-counters.ll Sun, 05 Sep 2021 18:51:19 +0000 Arthur Eubanks <aeubanks@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Instrumentation/SanitizerCoverage/inline-8bit-counters.ll#9558456b [SanitizerCoverage] Make __start_/__stop_ symbols extern_weakOn ELF, we place the metadata sections (`__sancov_guards`, `__sancov_cntrs`,`__sancov_bools`, `__sancov_pcs` in section groups (either `comdat any` or`comdat noduplicates`).With `--gc-sections`, LLD since D96753 and GNU ld `-z start-stop-gc` may garbagecollect such sections.

I traced the OOMerror to the destructor of SanitizerCoverage where we only callappendTo[Compiler]Used which calls appendToUsedList. I'm not sure where preciselyin appendToUsedList causes the OOM, but I am able to confirm that it's callingthis function *repeatedly* that causes the OOM. (I hacked sancov a bit such thatI can still create and destroy a new sancov on every function run, but only callappendToUsedList after all functions in the module have finished. This passes, butwhen I make it such that appendToUsedList is called on every sancov destruction,we hit OOM.)I don't think the OOM is from just adding to the SmallSet and SmallVector insideappendToUsedList since in either case for a given module, they'll have the samemax size. I suspect that when the existing llvm.compiler.used global is erased,the memory behind it isn't freed. I could be wrong on this though.This patch works around the OOM issue by just calling appendToUsedList at theend of every module run instead of function run. The same amount of constantsstill get added to llvm.compiler.used, abd we make the pass usage and logicsimpler by not having any inter-pass dependencies.Differential Revision: https://reviews.llvm.org/D66988llvm-svn: 370971 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/SanitizerCoverage/inline-8bit-counters.ll Wed, 04 Sep 2019 20:30:29 +0000 Leonard Chan <leonardchan@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Instrumentation/SanitizerCoverage/inline-8bit-counters.ll#007f674c Reland the "[NewPM] Port Sancov" patch from rL365838.
