And that this class contains `SigIndex` as its property isa little weird in the place, because the tag type's signature index isnot an inherent property of a tag but rather a reference to anothersection that changes after linking. This makes tag handling in thelinker also weird that tag-related methods are taking both `WasmTagType`and `WasmSignature` even though `WasmTagType` contains a signatureindex. This is because the signature index changes in linking so itdoesn't have any info at this point. This instead moves `SigIndex` to`struct WasmTag` itself, as we did for `struct WasmFunction` in D111104.In this CL, in lib/MC and lib/Object, this now treats tag types in thesame way as function types. Also in YAML, this removes `struct Tag`,because now it only contains the tag index. Also tags set `SigIndex` in`WasmImport` union, as functions do.I think this makes things simpler and makes tag handling more in linewith function handling. These two shares similar properties in that bothof them have signatures, but they are kind of nominal so having the samesignature doesn't mean they are the same element.Also a drive-by fix: the reserved 'attirubute' part's encoding changedfrom uleb32 to uint8 a while ago. This was fixed in lib/MC andlib/Object but not in YAML. This doesn't change object files because thefield's value is always 0 and its encoding is the same for the bothencoding.This is effectively NFC; I didn't mark it as such just because itchanged YAML test results.Reviewed By: sbc100, tlivelyDifferential Revision: https://reviews.llvm.org/D111086 List of files: /llvm-project-15.0.7/llvm/tools/obj2yaml/wasm2yaml.cpp Sat, 02 Oct 2021 02:07:41 +0000 Heejin Ahn <aheejin@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/tools/obj2yaml/wasm2yaml.cpp#c0039de2 [Object][WebAssemlby] Report function types (signatures).

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/tools/obj2yaml/wasm2yaml.cpp 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/tools/obj2yaml/wasm2yaml.cpp#a5a3659d [WebAssembly][yaml2obj][obj2yaml] Elem sections for nonzero tablesWith reference types, tables can have non-zero table numbers.
