And here 2/2 with the device -> arch mapping for gas.


Ok for trunk?

Johann


	* config/avr/avr.h (device_to_arch): Rename to device_to_ld.
	(avr_device_to_arch): Rename to avr_device_to_ld.
	(avr_device_to_as): New prototype.
	(EXTRA_SPEC_FUNCTIONS): Add device_to_as.
	(ASM_SPEC): Use device_to_as to get -mmcu= and -mno-skip-bug=.
	* config/avr/driver-avr.c (avr_device_to_as): New.
	(avr_device_to_arch): Rename to avr_device_to_ld.

CCing Richard in case this needs RM approval (I don't think so because 
the patch just changes ternary parts).

Ping #1 for:
