Subject: arm: remove dead predefines when using WMMX
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=31648852ad3f4b76e47dd468f88da5f4d36c134e;p=thirdparty%2Fgcc.git

arm: remove dead predefines when using WMMX

Since we no-longer enable iWMMXT, these predefines are no-longer enabled
when preprocessing C.  Remove them.

gcc/ChangeLog:

	* config/arm/arm-c.cc (arm_cpu_builtins):  Remove predefines
	for __IWWMXT__, __IWMMXT2__ and __ARM_WMMX.
