Re: PATCH: Add --alt-nops=short|long to x86/x86-64 assemblers

Hi H.J.

Since Pentium Pro, there are new nops instructions. This patch adds
--alt-nops=short|long to x86/x86-64 assemblers. --alt-nops=short
will generate a single nop instruction up to 10 bytes for code
alignment. --alt-nops=long will generate a single nop instruction up
to 15 bytes. Any comments?

I am not familiar with the x86 instruction set, so please can you explain why it is necessary to have these two different versions of the nop and why the user has to select one ? ie if the space to be padded is up to 10 bytes why can't the assembler just use the "short" version automatically and if it is longer than 10 bytes use the "long" version ?

Cheers
  Nick
