Hi Rudy,
I'm not seeing a intra-routine padding problem, using GCC 3.2.
I'm only seeing inter-routine padding, for alignment.
Could you send a short example that illustrates the problem?
Worse come to worse, you could change the ".p2align 4,,15" to ".p2align
4,144,15" (144 == 0x90) through some post-processing sed or perl magic
before the assembler gets a crack at it.
