The current code "over-aligns" the stack pointer so that the stack frame is effectively always mis-aligned by 4 bytes. But what we really want is that on function entry ((sp + 4) & 15) == 0, which matches what would happen if the stack were aligned before a "call" instruction. i386 and x86_64 are already fixed by d347f372273c2b3d86a66e2e1c94c790c208e166 Signed-off-by: Markus F.X.J.
