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/DataFlowSanitizer/origin_phi.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/DataFlowSanitizer/origin_phi.ll#c6b5a25e [dfsan] Replace dfs$ prefix with .dfsan suffixThe current naming scheme adds the `dfs$` prefix to allDFSan-instrumented functions. This breaks mangling and prevents stacktrace printers and other tools from automatically demangling functionnames.This new naming scheme is mangling-compatible, with the `.dfsan`suffix being a vendor-specific suffix:https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling-structureWith this fix, demangling utils would work out-of-the-box.Reviewed By: stephan.yichao.zhaoDifferential Revision: https://reviews.llvm.org/D104494 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/DataFlowSanitizer/origin_phi.ll Thu, 17 Jun 2021 21:55:05 +0000 George Balatsouras <gbalats@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Instrumentation/DataFlowSanitizer/origin_phi.ll#5b4dda55 [dfsan] Add full fast8 supportComplete support for fast8:- amend shadow size and mapping in runtime- remove fast16 mode and -dfsan-fast-16-labels flag- remove legacy mode and make fast8 mode the default- remove dfsan-fast-8-labels flag- remove functions in dfsan interface only applicable to legacy- remove legacy-related instrumentation code and tests- update documentation.Reviewed By: stephan.yichao.zhao, browneeeDifferential Revision: https://reviews.llvm.org/D103745 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/DataFlowSanitizer/origin_phi.ll Fri, 04 Jun 2021 22:34:02 +0000 George Balatsouras <gbalats@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Instrumentation/DataFlowSanitizer/origin_phi.ll#79b5280a [dfsan] Enable origin tracking with fast8 modeAll related instrumentation tests have been updated.Reviewed By: stephan.yichao.zhaoDifferential Revision: https://reviews.llvm.org/D100903 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/DataFlowSanitizer/origin_phi.ll Tue, 20 Apr 2021 22:31:58 +0000 George Balatsouras <gbalats@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Instrumentation/DataFlowSanitizer/origin_phi.ll#6a9a686c [dfsan] Tracking origins at phi nodesThis is a part of https://reviews.llvm.org/D95835.Reviewed-by: morehouseDifferential Revision: https://reviews.llvm.org/D98268 List of files: /llvm-project-15.0.7/llvm/test/Instrumentation/DataFlowSanitizer/origin_phi.ll Tue, 09 Mar 2021 04:13:16 +0000 Jianzhou Zhao <jianzhouzh@google.com>
