* [WebAssembly] Reverse the order of operands for br_ifDerek Schuff2015-11-161-4/+4
| | | | | | | | | | | | Summary: This is to match the new version in the spec Reviewers: sunfish Subscribers: jfb, llvm-commits, dschuff Differential Revision: http://reviews.llvm.org/D14519 llvm-svn: 253249
* [WebAssembly] Rename BR_IF_ to BR_IFDan Gohman2015-11-131-2/+2
| | | | | | | With MC-based instruction printing, we no longer need instruction names to mangle in hints about how they should be printed. llvm-svn: 252987

* [WebAssembly] Check in an initial CFG Stackifier passDan Gohman2015-09-161-0/+86
| | | | | | | | | | | | This pass implements a simple algorithm for conversion from CFG to wasm's structured control flow. It doesn't yet handle multiple-entry loops; that will be added in a future patch. It also adds initial support for switch statements.

* WebAssembly: basic bitcode → assembly CodeGen testJF Bastien2015-07-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Add a basic CodeGen bitcode test which (for now) only prints out the function name and nothing else. The current code merely implements the basic needed for the test run to not crash / assert. 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 WebAssembly backendDan Gohman2015-06-291-0/+28
This WebAssembly backend is just a skeleton at this time and is not yet functional. llvm-svn: 241022
