Getting to that point required: - Basic InstPrinter. - Basic AsmPrinter. - DiagnosticInfoUnsupported (not strictly required, but nice to have, duplicated from AMDGPU/BPF's ISelLowering). - Some SP and register setup in WebAssemblyTargetLowering. - Basic LowerFormalArguments. - GenInstrInfo. - Placeholder LowerFormalArguments. - Placeholder CanLowerReturn and LowerReturn. - Basic DAGToDAGISel::Select, which requiresGenDAGISel.inc as well as GET_INSTRINFO_ENUM with GenInstrInfo.inc. - Remove WebAssemblyFrameLowering::determineCalleeSaves and rely on default. - Implement WebAssemblyFrameLowering::hasFP, same as AArch64's implementation. Follow-up patches will implement a real AsmPrinter, which will require adding MI opcodes specific to WebAssembly.

[WebAssembly] Initial Disassembler. This implements a new table-gen emitter to create tables for a wasm disassembler, and a dissassembler to use them. Comes with 2 tests, that tests a few instructions manually. Is also able to disassemble large .wasm files with objdump reasonably. Not working so well, to be addressed in followups: - objdump appears to be passing an incorrect starting point. - since the disassembler works an instruction at a time, and it is disassembling stack instruction, it has no idea of pseudo register assignments. These registers are required for the instruction printing code that follows. For now, all such registers appear in the output as $0.

[WebAssembly] Reintroduce ARGUMENT moving logic Reinteroduce the code for moving ARGUMENTS back to the top of the basic block. While the ARGUMENTS physical register prevents sinking and scheduling from moving them, it does not appear to be sufficient to prevent SelectionDAG from moving them down in the initial schedule. This patch introduces a patch that moves them back to the top immediately after SelectionDAG runs. This is still hopefully a temporary solution. http://reviews.llvm.org/D14750 is one alternative, though the review has not been favorable, and proposed alternatives are longer-term and have other downsides. This fixes the main outstanding -verify-machineinstrs failures, so it adds -verify-machineinstrs to several tests. Differential Revision: http://reviews.llvm.org/D15377 llvm-svn: 255125

[WebAssembly] Support instruction selection for catching exceptions Summary: This lowers exception catching-related instructions: 1. Lowers `wasm.catch` intrinsic to `catch` instruction 2. Removes `catchpad` and `cleanuppad` instructions; they are not necessary after isel phase. (`MachineBasicBlock::isEHFuncletEntry()` or `MachineBasicBlock::isEHPad()` can be used instead.) 3. Lowers `catchret` and `cleanupret` instructions to pseudo `catchret` and `cleanupret` instructions in isel, which will be replaced with other instructions in `WebAssemblyExceptionPrepare` pass. 4. Adds 'WebAssemblyExceptionPrepare` pass, which is for running various transformation for EH. Currently this pass only replaces `catchret` and `cleanupret` instructions into appropriate wasm instructions to make this patch successfully run until the end. Currently this does not handle lowering of intrinsics related to LSDA info generation (`wasm.landingpad.index` and `wasm.lsda`), because they cannot be tested without implementing `EHStreamer`'s wasm-specific handlers. They are marked as TODO, which is needed to make isel pass. Also this does not generate `try` and `end_try` markers yet, which will be handled in later patches. This patch is based on the first wasm EH proposal.

[WebAssembly] Add a pass to create wrappers for function bitcasts. WebAssembly requires caller and callee signatures to match exactly.

[WebAssembly] Move register stackification and coloring to a late phase. Move the register stackification and coloring passes to run very late, after PEI, tail duplication, and most other passes. This means that all code emitted and expanded by those passes is now exposed to these passes. This also eliminates the need for prologue/epilogue code to be manually stackified, which significantly simplifies the code. This does require running LiveIntervals a second time. It's useful to think of these late passes not as late optimization passes, but as a domain-specific compression algorithm based on knowledge of liveness information. It's used to compress the code after all conventional optimizations are complete, which is why it uses LiveIntervals at a phase when actual optimization passes don't typically need it.

[WebAssembly] Reapply r252858, with svn add for the new file. Switch to MC for instruction printing. This encompasses several changes which are all interconnected: - Use the MC framework for printing almost all instructions. - AsmStrings are now live. - This introduces an indirection between LLVM vregs and WebAssembly registers, and a new pass, WebAssemblyRegNumbering, for computing a basic the mapping. This addresses some basic issues with argument registers and unused registers. - The way ARGUMENT instructions are handled no longer generates redundant get_local+set_local for every argument. This also changes the assembly syntax somewhat; most notably, MC's printing does not use sigils on label names, so those are no longer present, and push/pop now have a sigil to keep them unambiguous. The usage of set_local/get_local/$push/$pop will continue to evolve significantly. This patch is just one step of a larger change. llvm-svn: 252910

[WebAssembly] Added initial AsmParser implementation. It uses the MC framework and the tablegen matcher to do the heavy lifting. Can handle both explicit and implicit locals (-disable-wasm-explicit-locals). Comes with a small regression test. This is a first basic implementation that can parse most llvm .s output and round-trips most instructions succesfully, but in order to keep the commit small, does not address all issues. There are a fair number of mismatches between what MC / assembly matcher think a "CPU" should look like and what WASM provides, some already have workarounds in this commit (e.g. the way it deals with register operands) and some that require further work. Some of that further work may involve changing what the Disassembler outputs (and what s2wasm parses), so are probably best left to followups. Some known things missing: - Many directives are ignored and not emitted. - Vararg calls are parsed but extra args not emitted. - Loop signatures are likely incorrect. - $drop= is not emitted. - Disassembler does not output SIMD types correctly, so assembler can't test them.
