Staring at the Sun: Dalvik vs. ASM.js vs. Native
As many of you are probably already aware, Mozilla has recently gotten into the mobile OS space with Firefox OS. Firefox OS is built using web technologies like HTML, CSS, and of course Javascript. All Firefox OS apps are built on these technologies, including core platform apps. Given that app logic in Firefox OS will be written in Javascript, one of the questions facing Mozilla’s Javascript engi
asm.jsを手書きしつつフィボナッチで速度比較をしてみる
asm.jsを触ってみたので所感など。 asm.jsはJavaScriptのサブセットで、限られた型しか使えないが高速に動作する言語との事。とりあえずどの程度速くなるのか、計算量が多くなるfibonacciの実装で試してみた。参考資料はasm.jsの仕様ぐらいしか無かったのでこれを見ながら。 で、実際に書いてみると型がゆるゆるなJavaScriptのイメージは脆くも崩れ去り、厳格な型チェックの世界である事がわかった。コンパイル言語を書いている時の頭に切り換えないと、コンパイルエラーと延々格闘する事になる。まずはasm.jsのコードは次の形式で、module exportする。 function create_my_asm_module(stdlib, foreign, heap) { "use asm"; function hoge() {...} function fuga() {...
Compiling LLJS to asm.js
I'd like to announce that I have LLJS successfully compiling to asm.js, so we can tap into the amazing optimizations provided from it. This is just a start, and there are many things missing, but I'd like to show that it works.
