* | Optimize "squared" operations (#905) | Alon Zakai | 2017-02-16 | 1 | -23/+86 |
| | | | | * optimize 'almost' sign extends: when we can remove one entirely, then extra shifts can be left behind. with that in place, we can then optimize 'squared' operations like shl on shl, as doing so does not break our sign extend opts | ||||

* | Fix emitting of unreachable block/if/loop (#911) | Alon Zakai | 2017-02-16 | 4 | -10/+69 |
| | | | | | | | | | | | | | | | | | | | | | | * an unreachable block is one with an unreachable child, plus no breaks * document new difference between binaryen IR and wasm * fix relooper missing finalize * add a bunch of tests * don't assume that test/*.wast files print to themselves exactly; print to from.wast. this allows wast tests with comments in them * emit unreachable blocks as (block .. unreachable) unreachable * if without else and unreachable ifTrue is still not unreachable, it should be none * update wasm.js * cleanups * empty blocks have none type | ||||
* | Optimize precise mode integer ops (#907) | Alon Zakai | 2017-02-16 | 2 | -383/+83 |
| | | | | | | * improve precise integer operations: call into a wasm function to do the possibly-trapping div/rem, which handles the corner cases, instead of an ffi. also fix a bug in the existing parallel 64-bit code for this * remove no longer needed wasm.js-post.js file (it moved into emscripten repo) | ||||

* | asm2wasm debuginfo (#895) | Alon Zakai | 2017-02-07 | 6 | -8/+204 |
| | | | | | | | | | | | | * parse file/line comments in asm.js into debug intrinsics * convert debug intrinsics into annotations, and print them * ignore --debuginfo if not emitting text, as wasm binaries don't support that yet * emit full debug info when -g and emitting text; when -g and emitting binary, all we can do is the Names section * update wasm.js | ||||
* | Improve handling of implicit traps (#898) | Alon Zakai | 2017-02-06 | 9 | -60/+121 |
| | | | | | | | | * add --ignore-implicit-traps option, and by default do not ignore them, to properly preserve semantics * implicit traps can be reordered, but are side effects and should not be removed * add testing for --ignore-implicit-traps | ||||
