Hi, I don't see constant propagation mentioned at http://trac.webkit.org/wiki/SquirrelFishPerfIdeas. Has it been considered? (On a related note, is the above page up-to-date?) With JSC as of r57470: var a = 3; a + 7; produces the bytecode ... [ 7] mov r-15, 3(@k1) [ 10] add r0, r-15, 7(@k2) ... Worth pursuing? Reasonably feasible to implement in the compiler? Regards, Kent
