The latest is ths only one which generates '.p2align 4,,7' (see > attachments). Thanks. I see that gcc 2.95 aligns function entry points on the 4-byte boundaries, and uses ".p2align 4,,7" for jump targets. So it seems that the only thing we miss to have the better alignment is Binutils configured with 16-byte subsection alignment. Mark, did you succeed to resolve the problems with doing this?
