Derek Schuff ff171acf84 [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		2020-01-17 17:23:56 -08:00
