Also seems slightly wrong to require anyone adding a future 64-bit target to this if statement. The old code was X86-specific so would do no harm for non-X86. The new code means we only get this optimization for explicitly listed platforms. Would be slightly nicer if this could be written in a more direct way, like if (!tooFewGPRegisters()).

Reopening for Zan... I should have spotted that the comment was stale, sorry. At least that should be fixed.

The old code was X86-specific so would do no harm for non-X86. The new code means we only get this optimization for explicitly listed platforms. Would be slightly nicer if this could be written in a more direct way, like if (!tooFewGPRegisters()). I think you can just do `if (is64Bit())`. That's assuming all 64 bit platforms have enough registers for this, which I think is the case.

Modified the comment and the if-statement condition in r226616. https://trac.webkit.org/r226616
