* [WebAssembly] Update CodeGen test expectations after rL354697. NFCSam Clegg2019-02-231-2/+2
| | | | llvm-svn: 354705
* [WebAssembly] replaced .param/.result by .functypeWouter van Oortmerssen2018-11-191-4/+2
| | | | | | | | | | | | | | | | | | | | | Summary: This makes it easier/cleaner to generate a single signature from this directive. Also: - Adds the symbol name, such that we don't depend on the location of this directive anymore. - Actually constructs the signature in the assembler, and make the assembler own it. - Refactor the use of MVT vs ValType in the streamer and assembler to require less conversions overall. - Changed 700 or so tests to use it.

* [WebAssembly] Added default stack-only instruction mode for MC.Wouter van Oortmerssen2018-08-271-1/+1
| | | | | | | | | | | | | | | | | | | | | Summary: Made it convert from register to stack based instructions, and removed the registers. Fixes to related code that was expecting register based instructions. Added the correct testing flag to all tests, depending on what the format they were expecting so far. Translated one test to stack format as example: reg-stackify-stack.ll tested: llvm-lit -v `find test -name WebAssembly` unittests/MC/* Reviewers: dschuff, sunfish Subscribers: sbc100, jgravelle-google, eraman, aheejin, llvm-commits, jfb Differential Revision: https://reviews.llvm.org/D51241 llvm-svn: 340750

* [WebAsembly] Update default triple in test files to wasm32-unknown-unkown.Sam Clegg2018-05-101-1/+1
| | | | | | | | | | Summary: The final -wasm component has been the default for some time now. Subscribers: jfb, dschuff, jgravelle-google, eraman, aheejin, JDevlieghere, sunfish, llvm-commits Differential Revision: https://reviews.llvm.org/D46342 llvm-svn: 332007
* [WebAssembly] Convert the remaining unit tests to the new wasm-object-file ↵Dan Gohman2017-02-281-2/+2
| | | | | | | | | | | target. To facilitate this, add a new hidden command-line option to disable the explicit-locals pass. That causes llc to emit invalid code that doesn't have all locals converted to get_local/set_local, however it simplifies testwriting in many cases. llvm-svn: 296540
* [WebAssembly] Optimize away return instructions using fallthroughs.Dan Gohman2016-05-211-1/+1
| | | | | | | | | This saves a small amount of code size, and is a first small step toward passing values on the stack across block boundaries. Differential Review: http://reviews.llvm.org/D20450 llvm-svn: 270294
* [WebAssembly] Define WebAssembly-specific relocation codes.Dan Gohman2016-01-111-2/+2
| | | | | | | | Currently WebAssembly has two kinds of relocations; data addresses and function addresses. This adds ELF relocations for them, as well as an MC symbol kind to indicate which type of relocation is needed. llvm-svn: 257416
* [WebAssembly] Add -m:e to the target triple.Dan Gohman2016-01-071-1/+1
| | | | | | | This enables ELF-style name mangling, which primarily means using ".L" for private symbols. llvm-svn: 257020
* [WebAssembly] Add type prefixes to call instructionsDan Gohman2015-12-141-2/+2
| | | | | | | | | Add return type information to call and call_indirect instructions. This allows them to be disambiguated without knowledge of the callee. Differential Revision: http://reviews.llvm.org/D15484 llvm-svn: 255565
* [WebAssembly] Implement direct calls to external symbols.Dan Gohman2015-12-051-0/+26
