* config/tc-i386.c (md_assemble): Swap segments too for intel mode
string instructions.
(i386_operand_modifier): Set i.suffix = WORD_MNEM_SUFFIX for SHORT.
(i386_intel_memory_operand): After finding a segment override,
check again for no `[' before looking for a displacement. Bomb if
more than one displacement rather than silently discarding the
second and subsequent ones. Free strings malloc'd by
build_displacement_string.
2000-02-24 Catherine Moore <clm@cygnus.com>
* config/obj-som.c (obj_pseudo_table): Add "weak".
