* [WebAssembly] replaced .param/.result by .functypeWouter van Oortmerssen2018-11-191-6/+6
| | | | | | | | | | | | | | | | | | | | | 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

* [WebAssembly] Basic support for Wasm object file encoding.Dan Gohman2017-02-241-1/+1
| | | | | | | | | With the "wasm32-unknown-unknown-wasm" triple, this allows writing out simple wasm object files, and is another step in a larger series toward migrating from ELF to general wasm object support. Note that this code and the binary format itself is still experimental. llvm-svn: 296190
* [WebAssembly] Add tests for negative offsets with global variable addresses.Dan Gohman2016-01-251-0/+18

* [WebAssembly] Re-enable a test.Dan Gohman2016-01-151-4/+1
| | | | | | | Out-of-tree projects that don't support this can disable the test for themselves rather than having it disabled in LLVM itself. llvm-svn: 257960
* [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: remove 'external' from testJF Bastien2015-12-231-1/+4
| | | | | | | | | | | | Summary: Linker testing was sad at seeing an unresolved external symbol. For now don't do that: it's valid but we're not playing with multi-file linking yet, and the LLVM tests are used as hacky sanity tests for single-file linking (the GCC torture tests are much better for this purpose). Another solution would be to use '.extern' to make the intent explicit (don't simple-file link this, there's an unresolved symbol), some assemblers use '.extern' while others ignore it, so we wouldn't really be inventing anything new.
