Fold handling of VFP control registers into the generic register
parser.

zw


[-- Attachment #2: Type: text/plain, Size: 331 bytes --]


	* config/tc-arm.c (arm_reg_type): Add REG_TYPE_VFC,
	(reg_expected_msgs): Add matching message.
	(reg_names): Add definitions for fpsid, fpscr, fpexc in class VFC.
	(do_vfp_reg_from_ctrl, do_vfp_ctrl_from_reg): Use reg_or_fail
	with REG_TYPE_VFC and shift 16.
	(vfp_reg, vfp_regs, vfp_psr_parse, vfp_psr_required_here): Delete.
