I was wondering why to subtract sizeof(Register) * 4 from sp, why not sizeof(CallerFrameAndPC)? (And then, the arithmetic is not even necessary, since the result is already in regT1.)

A stack/call frame layout problem also exists on ARM32. It would be worth looking at https://bugs.webkit.org/show_bug.cgi?id=132740 . There, a highly similar approach has been suggested (not reviewed yet / titled dirty hack).
