An extra pass is added to Codegen to collect information for this purpose, since AsmPrinter is normally single pass / streaming as well, and would otherwise generate this information on the fly.A `-no-type-check` flag was added to llvm-mc (and any other tools that take asm input) that surpresses type errors, as a quick escape hatch for tests that were not intended to be type correct.This is a first version of the type checker that ignores control flow, i.e. it checks that types are correct along the linear path, but not the branch path. This will still catch most errors. Branch checking could be added in the future.Differential Revision: https://reviews.llvm.org/D104945 List of files: /llvm-project/lld/test/wasm/comdat-sections.s Mon, 07 Jun 2021 19:10:47 +0000 Wouter van Oortmerssen <aardappel@gmail.com> http://src.rcs.uwaterloo.ca:8080/source/history/llvm-project/lld/test/wasm/comdat-sections.s#dd6412c05c1039e582a970da1aee62cdde75c892 [WebAssembly][lld] Exclude COMDAT sectionsAllow exclusion/discarding of custom sections with COMDAT groups.It piggybacks on the existing COMDAT-handling code, but applies to custom sections as well.Differential Revision: https://reviews.llvm.org/D92950 List of files: /llvm-project/lld/test/wasm/comdat-sections.s Wed, 09 Dec 2020 18:57:27 +0000 Derek Schuff <dschuff@chromium.org>
