* Remove unused class variables.Eric Christopher2015-12-171-5/+3
| | | | llvm-svn: 255939
* [WebAssembly] Switch WebAssemblyMCAsmInfo.h from MCAsmInfo to MCAsmInfoELF.Dan Gohman2015-12-171-2/+2
| | | | llvm-svn: 255925
* Fix unused variable warning in release builds. NFC.Diego Novillo2015-12-171-3/+1
| | | | llvm-svn: 255897
* [WebAssembly] Experimental ELF writer supportDan Gohman2015-12-176-0/+288
| | | | | | | | | This creates the initial infrastructure for writing ELF output files. It doesn't yet have any implementation for encoding instructions. Differential Revision: http://reviews.llvm.org/D15555 llvm-svn: 255869
* [WebAssembly] Trim some unneeded #includes.Dan Gohman2015-12-081-1/+0
| | | | llvm-svn: 254994
* [WebAssembly] Minor clang-format and selected clang-tidy cleanups. NFC.Dan Gohman2015-11-291-2/+2
| | | | llvm-svn: 254267
* [WebAssembly] Remove incomplete MCCodeEmitter bits.Dan Gohman2015-11-232-4/+0
| | | | | | These are parts of a separate patch that I accidentally included in r253878. llvm-svn: 253892
* [WebAssembly] Emit .param, .result, and .local through MC.Dan Gohman2015-11-233-1/+10
| | | | | | This eliminates one of the main remaining uses of EmitRawText. llvm-svn: 253878
* [WebAssembly] Add WebAssemblyMCInstLower.cpp.Dan Gohman2015-11-051-0/+9
| | | | | | | This isn't used yet; it's just a start towards eventually using MC to do instruction printing, and eventually binary encoding. llvm-svn: 252194
* [WebAssembly] Switch to a more traditional assembly syntaxDan Gohman2015-10-061-10/+0
| | | | | | | | | | | This new syntax is built around putting each instruction on its own line in a "mnemonic op, op, op" like syntax. It also uses conventional data section directives like ".byte" and so on rather than requiring everything to be in hierarchical S-expression format. This is a more natural syntax for a ".s" file format from the perspective of LLVM MC and related tools, while remaining easy to translate into other forms as needed. llvm-svn: 249364
* WebAssembly: add small FIXME for AsmPrinter.JF Bastien2015-08-261-0/+1
| | | | | | Suggested by @sunfish as a follow-up to r245982. llvm-svn: 245996
* WebAssembly: comment out .globl when printing textual assemblyJF Bastien2015-08-251-1/+4
| | | | | | Do the same for .weak (not implemented for now, but may as well to it). Update comment string to two semicolons. llvm-svn: 245982
* WebAssembly: MCAsmInfo only has one syntax variant for now.JF Bastien2015-07-281-5/+3
| | | | | | | | | | Summary: MCAsmInfo is set up with the default AssemblerDialect, which is zero. Subscribers: llvm-commits, sunfish, jfb Differential Revision: http://reviews.llvm.org/D11567 llvm-svn: 243452
* WebAssembly: more MCAsmInfo nits.JF Bastien2015-07-271-5/+1
| | | | | | | | | | Summary: As suggested by sunfish. Subscribers: jfb, llvm-commits, sunfish Differential Revision: http://reviews.llvm.org/D11544 llvm-svn: 243339
* WebAssembly: minor MCAsmInfo fixesJF Bastien2015-07-271-1/+8
| | | | | | | | | | | | Summary: Fix pointer / callee-save stack sto size. Update comment character to be LISP-ish. Subscribers: llvm-commits, sunfish, jfb Differential Revision: http://reviews.llvm.org/D11537 llvm-svn: 243326
* WebAssembly: basic bitcode → assembly CodeGen testJF Bastien2015-07-222-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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: basic instructions todo, and basic register info.JF Bastien2015-07-102-0/+6
| | | | | | | | | | | | | | Summary: This code is based on AArch64 for modern backend good practice, and NVPTX for virtual ISA concerns. Reviewers: sunfish Subscribers: aemerson, llvm-commits, jfb Differential Revision: http://reviews.llvm.org/D11070 llvm-svn: 241923
* [WebAssembly] Define separate Target instances for 32-bit and 64-bit.Dan Gohman2015-07-012-2/+3

* [WebAssembly] Initial WebAssembly backendDan Gohman2015-06-297-0/+236
This WebAssembly backend is just a skeleton at this time and is not yet functional. llvm-svn: 241022
