gas:

* config/tc-i386.c (i386_operand_modifier): Only match
modifiers SHORT and FLAT if they are followed by a space.
(parse_register): When `allow_naked_reg' is set, do not confuse
identifiers that start with a register name with a register.
gas/testsuite:
2000-10-15 Diego Novillo <dnovillo@cygnus.com>
* intel.s, intel.d: Add new tests for naked registers using intel
syntax.
