wasm-merge tool: combines two wasm files into a larger one, handling collisions, and aware of the dynamic linking conventions. it does not do full static linking, but may eventually.

See https://github.com/WebAssembly/binaryen/issues/914.
* extensible name section support: read function names, too
* c-api-unused-mem.txt: change expected size to match new name section
* * check subsection size matches
* print warning for unknown name subsections (including the local
section)

New binaryen.js implementation, based on the C API underneath and with a JS-friendly API on top. See docs under docs/ for API details.

* fix eq/ne of sign-ext with a constant, when the constant can never be equal to it as it has the effective sign bit but not the upper bits above it set, which the sign-ext would emit

* optimize pow(x,2) => x*x
* optimize pow(x, 0.5) => sqrt(x)

* fix a bug where compared sign-exts of different sizes were turned into zero-exts
* fix a bug where we consider an almost sign-ext as ok to change the sign of a load inside it, ignoring that the load has the extra shifting

unruly (#928)
|
| |
|
| |
Simple local common subexpression elimination. Useful mostly to reduce code size (as VMs do GVN etc.). Enabled by default in -Oz.
|
| |
|
| |
* use 3 modes for potentially trapping ops in asm2wasm: allow (just emit a potentially trapping op), js (do exactly what js does, even if it takes a slow ffi to do it), and clamp (avoid the trap by clamping as necessary)

* asm2wasm should not promote an overloaded import result to f64 if it is a single type and void

* Fully handle EM_ASM in s2wasm
* Iterate with size_ts, remember to erase from importsMap as well
* Fix dot_s test EM_ASM signatures
* Move Name out to its own file, support/name.h
* Move removeImportsWithSubstring out of Module class
|
| |
|
|
| |
* fix asm2wasm import type setting - set the type of used calls based on the context, early, so it's valid in the optimizer

fix the maxBits of a signed load, which this uncovered - all the bits may be used in such a case

* 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
|
| | |
|
| |
|
|
|
|
| |
* optimize sign-extend output
* optimize sign-extend input
|

* update wasm version to 0x01, in prep for release, and since browsers are ready to accept it
* update wasm.js

* 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
|
| |
|
|

|

* 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)

* 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
|
| |
|
|
|
|
|
|
| |
* 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

not execute any more (#890)
|
| |
|
| |
Emscripten's mmap2 syscall started using memalign instead of malloc with kripken/emscripten#4874, so we need to export that as well.
