Browse source 
* configure.in (gcc_cv_as_ix86_cmov_sun_syntax): Check if
	assembler supports Sun syntax for cmov.
	* configure: Regenerate.
	* config.in: Likewise.
	* config/i386/i386.c: Rename CMOV_SUN_AS_SYNTAX to
	HAVE_AS_IX86_CMOV_SUN_SYNTAX.
	* config/i386/sol2.h (CMOV_SUN_AS_SYNTAX): Remove.
	Fixes PR target/12101.
