* Migrate function attribute "no-frame-pointer-elim"="false" to ↵Fangrui Song2019-12-241-2/+2
| | | | "frame-pointer"="none" as cleanups after D56351
* [WebAssembly] Update CodeGen test expectations after rL354697. NFCSam Clegg2019-02-231-7/+7

* [WebAssembly] replaced .param/.result by .functypeWouter van Oortmerssen2018-11-191-7/+7
| | | | | | | | | | | | | | | | | | | | | 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] Cleanup unused declares in test code. NFC.Sam Clegg2018-11-161-1/+8
| | | | | | | | | In one case probably you have be using it, in the other it looks like it was redundant. Differential Revision: https://reviews.llvm.org/D54644 llvm-svn: 347098
* [WebAssembly] Added default stack-only instruction mode for MC.Wouter van Oortmerssen2018-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | 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

* [wasm] Update two tests for r308025 which causes scheduling changes dueChandler Carruth2017-07-151-5/+4

* [WebAssembly] Emit type signatures for declared functionsDerek Schuff2016-06-031-0/+73
| | | | | | | | | | | | | | | | | | | | | Under emscripten, C code can take the address of a function implemented in Javascript (which is exposed via an import in wasm). Because imports do not have linear memory address in wasm, we need to generate a thunk to be the target of the indirect call; it call the import directly. To make this possible, LLVM needs to emit the type signatures for these functions, because they may not be called directly or referred to other than where the address is taken. This uses s new .s directive (.functype) which specifies the signature. Differential Revision: http://reviews.llvm.org/D20891 Re-apply r271599 but instead of bailing with an error when a declared function has multiple returns, replace it with a pointer argument. Also add the test case I forgot to 'git add' last time around. llvm-svn: 271703
* Revert "[WebAssembly] Emit type signatures for declared functions"Derek Schuff2016-06-021-70/+0
| | | | | | | | This reverts r271599, it broke the integration tests. More places than I expected had nontrival return types in imports, or else the check was wrong. llvm-svn: 271606
