[llvm-readobj] Update tests because of changes in llvm-readobj behavior This patch updates tests using llvm-readobj and llvm-readelf, because soon reading from stdin will be achievable only via a '-' as described here: https://bugs.llvm.org/show_bug.cgi?id=46400. Patch with changes to llvm-readobj behavior is here: https://reviews.llvm.org/D83704 Differential Revision: https://reviews.llvm.org/D83912 Reviewed by: jhenderson, MaskRay, grimar

[WebAssembly] Track frame registers through VReg and local allocation This change has 2 components: Target-independent: add a method getDwarfFrameBase to TargetFrameLowering. It describes how the Dwarf frame base will be encoded. That can be a register (the default), the CFA (which replaces NVPTX-specific logic in DwarfCompileUnit), or a DW_OP_WASM_location descriptr. WebAssembly: Allow WebAssemblyFunctionInfo::getFrameRegister to return the correct virtual register instead of FP32/SP32 after WebAssemblyReplacePhysRegs has run. Make WebAssemblyExplicitLocals store the local it allocates for the frame register. Use this local information to implement getDwarfFrameBase The result is that the DW_AT_frame_base attribute is correctly encoded for each subprogram, and each param and local variable has a correct DW_AT_location that uses DW_OP_fbreg to refer to the frame base. This is a reland of rG3a05c3969c18 with fixes for the expensive-checks and Windows builds Differential Revision: https://reviews.llvm.org/D71681

[DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label. In order to set breakpoints on labels and list source code around labels, we need collect debug information for labels, i.e., label name, the function label belong, line number in the file, and the address label located. In order to keep these information in LLVM IR and to allow backend to generate debug information correctly. We create a new kind of metadata for labels, DILabel. The format of DILabel is !DILabel(scope: !1, name: "foo", file: !2, line: 3) We hope to keep debug information as much as possible even the code is optimized. So, we create a new kind of intrinsic for label metadata to avoid the metadata is eliminated with basic block. The intrinsic will keep existing if we keep it from optimized out. The format of the intrinsic is llvm.dbg.label(metadata !1) It has only one argument, that is the DILabel metadata. The intrinsic will follow the label immediately. Backend could get the label metadata through the intrinsic's parameter. We also create DIBuilder API for labels to be used by Frontend. Frontend could use createLabel() to allocate DILabel objects, and use insertLabel() to insert llvm.dbg.label intrinsic in LLVM IR.

[WebAssembly] MC: Ensure that FUNCTION_OFFSET relocations are always against function symbols. The getAtom() method wasn't doing what we needed in all cases. We want the symbols for the function which defines that section. We can compute this easily enough and we know that we have at most one function in each section. Once this lands I will revert rL331412 which is no longer needed. Fixes PR37409 Differential Revision: https://reviews.llvm.org/D46970 llvm-svn: 332517
