Subject: Clean base_reg and assign correct values to regs for input_output_operand (%dx).
X-Git-Tag: binutils-2_42~614
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f0a4cb15c3fea691388dbce15f48b7485f1d40f9;p=thirdparty%2Fbinutils-gdb.git

Clean base_reg and assign correct values to regs for input_output_operand (%dx).

For special processing of input and output operands (%dx),
the state of some variables needs to be cleaned.

gas/ChangeLog:

	* config/tc-i386.c (i386_att_operand): Assign values to regs and
	clean i.base_reg for input output operand (%dx).
