3 * config/tc-i386.c (optimize_imm): Adjust immediates to only those
4 permissible for the selected instruction suffix.

6 guessing of a 'q' suffix if the instruction doesn't support it is
7 pointless, because only an 'l' suffix can be guessed in this place.

2386 first version is needed.

2388 (md_convert_frag): Go through the fixups for a relaxable macro and
2389 mark those that belong to the unneeded alternative as done. If the

2391 for the deleted first alternative.
