Summary: One for register based, much like the existing definitions, and one for stack based (suffix _S). This allows us to use registers in most of LLVM (which works better), and stack based in MC (which results in a simpler and more readable assembler / disassembler). Tried to keep this change as small as possible while passing tests, follow-up commit will: - Add reg->stack conversion in MI. - Fix asm/disasm in MC to be stack based. - Fix emitter to be stack based. tests passing: llvm-lit -v `find test -name WebAssembly` test/CodeGen/WebAssembly test/MC/WebAssembly test/MC/Disassembler/WebAssembly test/DebugInfo/WebAssembly test/CodeGen/MIR/WebAssembly test/tools/llvm-objdump/WebAssembly Reviewers: dschuff, sbc100, jgravelle-google, sunfish Subscribers: aheejin, JDevlieghere, llvm-commits Differential Revision: https://reviews.llvm.org/D48183 llvm-svn: 334985
