Reload generating memory ref in memory ref

Hi -- I'm running into a situation where reload is replacing a pseudo-register in an insn with a memory reference. The problem is that this is happening in a memory ref. The initial pattern is something like (set (reg/v:SI 1) (mem/s:SI (plus:SI (reg/f:SI 30) (const_int 4)) )) A

Re: Transforms on SSA form

There are documented methods of SSA decomposition. The naive method is a simple reversal of SSA composition: SSA composition: rename variables (typically by adding suffix), add phi nodes SSA decomposition: rename variables (by dropping suffix), remove phi nodes The short answer to your quest

Hello, I did not find any documentation of a "rep ret" instruction, at http://www.intel.com/design/processor/manuals/253667.pdf they just say: "The behavior of the REP prefix is undefined when used with non-strings instructions". Any pointers? Thanks, Etienne. etienne:~$ gcc --version gcc
