NFC.This patch renames the "Initial" member of WasmLimits to the name usedin the spec, "Minimum".In the core WebAssembly specification, the Limits data type has onerequired "min" member and one optional "max" member, indicating theminimum required size of the corresponding table or memory, and themaximum size, if any.Although the WebAssembly spec does instantiate locally-defined tablesand memories with the initial size being equal to the minimum size, itcan't impose such a requirement for imports. It doesn't make sense torequire an initial size for a memory import, for example. The compilercan only sensibly express the minimum and maximum sizes.Seehttps://github.com/WebAssembly/js-types/blob/master/proposals/js-types/Overview.md#naming-of-size-limitsfor a related discussion that agrees that the right name of "initial" is"minimum" when querying the type of a table or memory from JavaScript.(Of course it still makes sense for JS to speak in terms of an initialsize when it explicitly instantiates memories and tables.)Differential Revision: https://reviews.llvm.org/D99186 List of files: /llvm-project-15.0.7/llvm/test/MC/WebAssembly/comdat.ll Tue, 23 Mar 2021 13:46:32 +0000 Andy Wingo <wingo@igalia.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/MC/WebAssembly/comdat.ll#8d396aca [WebAssembly] Support COMDAT sections in assembly syntaxThis CL changes the asm syntax for section flags, making them more like ELF(previously "passive" was the only option).

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.

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/comdat.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/comdat.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/comdat.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/comdat.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/comdat.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/comdat.ll#2e150409 [WebAssembly] Update MC for bulk memorySummary:Rename MemoryIndex to InitFlags and implement logic for determiningdata segment layout in ObjectYAML and MC.
