Enginesthat don't support bulk memory operations will not recognize theDataCount section and will report validation errors, but that's okbecause object files aren't supposed to be run directly anyway.Reviewers: aheejin, dschuff, sbc100Subscribers: jgravelle-google, hiraditya, sunfish, rupprecht, llvm-commitsTags: #llvmDifferential Revision: https://reviews.llvm.org/D60623llvm-svn: 358315 List of files: /llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll Fri, 12 Apr 2019 22:27:48 +0000 Thomas Lively <tlively@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll#3f34e1b8 [WebAssembly] Merge used feature sets, update atomics linkage policySummary:It does not currently make sense to use WebAssembly features in some functionsbut not others, so this CL adds an IR pass that takes the union of all usedfeature sets and applies it to each function in the module. This allows us toprevent atomics from being lowered away if some function has opted in to usingthem. When atomics is not enabled anywhere, we detect whether there exists anyatomic operations or thread local storage that would be stripped and disallowlinking with objects that contain atomics if and only if atomics or tls arestripped. When atomics is enabled, mark it as used but do not require it ofother objects in the link. These changes allow libraries that do not use atomicsto be built once and linked into both single-threaded and multithreadedbinaries.Reviewers: aheejin, sbc100, dschuffSubscribers: jgravelle-google, hiraditya, sunfish, jfb, llvm-commitsTags: #llvmDifferential Revision: https://reviews.llvm.org/D59625llvm-svn: 357226 List of files: /llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll Fri, 29 Mar 2019 00:14:01 +0000 Thomas Lively <tlively@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll#f6f4f843 [WebAssembly] Target features sectionSummary:Implements a new target features section in assembly and object filesthat records what features are used, required, and disallowed inWebAssembly objects. The linker uses this information to ensure thatall objects participating in a link are feature-compatible and recordsthe set of used features in the output binary for use by optimizersand other tools later in the toolchain.The "atomics" feature is always required or disallowed to preventlinking code with stripped atomics into multithreaded binaries. Otherfeatures are marked used if they are enabled globally or on anyfunction in a module.Future CLs will add linker flags for ignoring feature compatibilitychecks and for specifying the set of allowed features, implement usingthe presence of the "atomics" feature to control the type of memoryand segments in the linked binary, and add front-end flags forrelaxing the linkage policy for atomics.Reviewers: aheejin, sbc100, dschuffSubscribers: jgravelle-google, hiraditya, sunfish, mgrang, jfb, jdoerfert, llvm-commitsTags: #llvmDifferential Revision: https://reviews.llvm.org/D59173llvm-svn: 356610 List of files: /llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll Wed, 20 Mar 2019 20:26:45 +0000 Thomas Lively <tlively@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll#3c20b34d [WebAssembly] Remove trailing whitespaces in tests (NFC)Reviewers: sbc100Subscribers: dschuff, jgravelle-google, sunfish, llvm-commitsTags: #llvmDifferential Revision: https://reviews.llvm.org/D58955llvm-svn: 355472 List of files: /llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll Wed, 06 Mar 2019 02:00:22 +0000 Heejin Ahn <aheejin@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll#f3b4f990 [WebAssembly] Remove uses of ThreadModelSummary:In the clang UI, replaces -mthread-model posix with -matomics as thesource of truth on threading. In the backend, replaces-thread-model=posix with the atomics target feature, which is nowcollected on the WebAssemblyTargetMachine along with all other usedfeatures. These collected features will also be used to emit thetarget features section in the future.The default configuration for the backend is thread-model=posix and noatomics, which was previously an invalid configuration. This changemakes the default valid because the thread model is ignored.A side effect of this change is that objects are never emitted withpassive segments. It will instead be up to the linker to decidewhether sections should be active or passive based on whether atomicsare used in the final link.Reviewers: aheejin, sbc100, dschuffSubscribers: mehdi_amini, jgravelle-google, hiraditya, sunfish, steven_wu, dexonsmith, rupprecht, jfb, jdoerfert, cfe-commits, llvm-commitsTags: #clang, #llvmDifferential Revision: https://reviews.llvm.org/D58742llvm-svn: 355112 List of files: /llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll Thu, 28 Feb 2019 18:39:08 +0000 Thomas Lively <tlively@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/MC/WebAssembly/explicit-sections.ll#2e150409 [WebAssembly] Update MC for bulk memorySummary:Rename MemoryIndex to InitFlags and implement logic for determiningdata segment layout in ObjectYAML and MC.
