| == Active ==
| | OdinMonkey was the optimizing AsmJS compiler. |
| * Fix lazy-parsing/decompression memory-spike and performance hit for huge js files ({{bug|938385}}).
| |
| * Standardize then implement SIMD extensions to JS ({{bug|894105}}) and then incorporate into asm.js
| |
| * Land experimental SharedArrayBuffer (pref'd off, {{bug|933001}}) and use this to add experimental pthreads support to Emscripten and evaluate on threaded codebases in preparation for a standards proposal.
| |
|
| |
|
| == Planned next projects ==
| |
| * Record enough information at compile time so that asm.js functions show up in:
| |
| ** the builtin FF profiler ({{bug|947996}})
| |
| ** Error.stack
| |
| * Optimize constant-additions in masked heap accessed: {{bug|915157}}
| |
| * Add && and || to asm.js to avoid sub-optimal control flow ({{bug|919052}}).
| |
| * Add missing math constants ({{bug|878488}})
| |
| * Remove num-locals ({{bug|916612}}) and num-lines ({{bug|916564}}) parser limits.
| |
| * Mitigate 32-bit OOM problems: ({{bug|865959}})
| |
| * ArrayBuffer.prototype.resize ({{bug|927182}}): to allow growable heap
| |
|
| |
| == Possible further optimization projects ==
| |
| * Compress asm.js cache entries
| |
| * Further improve load-time:
| |
| ** Start general JS parsing before the entire JS script has completed downloading so that asm.js compilation can overlap
| |
| ** asm.js parser: Avoid building an intermediate parse tree; type check during recursive descent {{bug|854061}}
| |
| * Further improve heap access performance : {{bug|870743}}, {{bug|897425}}
| |
| * Further improve FFI calls : {{bug|882399}}, {{bug|886411}}, also stop spilling non-volatile registers
| |
| * Improve x86/ARM asm.js-to-asm.js ABI : {{bug|861785}}
| |
| * Extend the asm.js signal handler tricks to:
| |
| ** Remove stack overflow checks
| |
| ** Remove idiv branching
| |
| ** Remove double-to-int conversion branching (see also {{bug|818750}})
| |
|
| |
| == Possible asm.js extensions that don't extend JS ==
| |
| * Effectively support 'goto' (even computed 'goto') by formalizing a pattern of while+switch that gets compiled as if it was goto
| |
| * Extend asm.js to better support dynamically linking asm.js modules (a mutable, callable array argument to asm.js module, like the PLT)
| |
| * Add enough try/catch to asm.js to allow compilation of C++ exceptions using the zero-cost implementation strategy
| |
| * Add DataView to avoid the alignment mask on asm.js heap accesses (this is mostly a problem of DataView being slow in all browsers)
| |
|
| |
| == Proposed future JS features that would be useful to asm.js ==
| |
| * ArrayBuffer.prototype.discard ({{bug|855669}}): to allow madvise(DONTNEED)
| |
| * FunctionPromise: {{bug|854627}}
| |
| * Typed Objects: ([http://wiki.ecmascript.org/doku.php?id=harmony:typed_objects Typed Objects])
| |
| ** This feature comes with float32/uint64/int64 value types, which would be useful as scalar types in asm.js.
| |
| ** Formalize Typed Object "class declarations" in asm.js which could make asm.js a target for JVM/CLR/TypeScript (and allow these languages to reuse the builtin JS GC)
