| | OdinMonkey was the optimizing AsmJS compiler. |
| * Continue iteration on [https://github.com/johnmccutchan/ecmascript_simd SIMD proposal] and implementation/optimization in Ion/Odin.
| |
| * [https://github.com/lars-t-hansen/ecmascript_sharedmem SharedArrayBuffer]
| |
| ** Share source text between workers: {{bug|1211723}}
| |
| ** Share asm.js machine code between workers: (TODO)
| |
| * Baseline compilation: {{bug|1157624}}, {{bug|1169167}}
| |
|
| |
|
| == Possible further load-time optimizations ==
| |
| * Parse and AOT compile while downloading: {{bug|1061886}}
| |
| * Remove async-script requirement for asm.js caching:
| |
| ** Maybe remove it from QuotaManager: {{bug|961057}}
| |
| ** More likely, just take (large) script parsing off the main thread: {{bug|1084009}}
| |
| * Share compiled code between workers: {{bug|1168981}}
| |
|
| |
| == Possible further throughput optimizations ==
| |
| * Meta bug: {{bug|1200406}}
| |
| * Optimize sin/cos: {{bug|967709}}
| |
| * Use callee-saved registers: {{bug|985065}}
| |
| * Heap access: {{bug|1145676}}, {{bug|897425}}, {{bug|870743}}, {{bug|983131}}, {{bug|1056027}}, {{bug|1136276}}
| |
| * Optimize add-with-overflow: {{bug|1043365}}
| |
| * Optimize min/max: {{bug|1060635}}
| |
| * For asm.js->asm.js calls on x86, pass the return value via xmm register, not fp stack
| |
| * Remove branching from double-to-int conversion using signal handler (see also {{bug|818750}})
| |
| * Optimize calls into ({{bug|962641}}), out of ({{bug|1000632}}), and between ({{bug|982036}}) asm.js modules.
| |
| * Signed comparisons: {{bug|1141407}}
| |
|
| |
| == Possible asm.js extensions that don't require new JS features ==
| |
| * Zero-cost exception handling: {{bug|1065089}}
| |
| * Extend asm.js to allow proper tail calls for all return types and do the tail-call optimization
| |
| * 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 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 ==
| |
| * int64 arithmetic: https://gist.github.com/BrendanEich/4294d5c212a6d2254703
| |
| * ArrayBuffer.prototype.discard ({{bug|855669}}): to allow madvise(DONTNEED)
| |
| * 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)
| |
| * FunctionPromise: {{bug|854627}}, or perhaps just make some functions (asm.js, no-free-variables) structured-cloneable
| |
| * Add way to programmatically observe whether asm.js validated: {{bug|952847}}
| |
|
| |
| == Usability improvements ==
| |
| * Add about:config option to throw for out-of-bounds or unaligned access ({{bug|1088655}})
| |
| * Fix asm.js caching browser interop ({{bug|527667}}, {{bug|1047105}}
