Funny how it isn't possible to align instructions in the AIX
assembler, you mentioned it doesn't support .p2align.  Is there
anyway it can be done by explicitly inserting nops into the insn
stream?  Perhaps via machine-dependent reorg or something similar?

I've no idea whether GCC already has support for aligning
instructions without the assistance of assembler pseudo-ops?
