Subject: rs6000: Remove useless operands[3]
X-Git-Tag: basepoints/gcc-16~8846
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1a87deddf470c728e85cc9ca802b51ed2b1efbd6;p=thirdparty%2Fgcc.git

rs6000: Remove useless operands[3]

As shown, three uses of operands[3] are totally useless, so
this patch is to remove them to avoid any confusion.

gcc/ChangeLog:

	* config/rs6000/rs6000.md (@ieee_128bit_vsx_neg<IEEE128>2): Remove
	the use of operands[3].
	(@ieee_128bit_vsx_neg<IEEE128>2): Likewise.
	(*ieee_128bit_vsx_nabs<mode>2): Likewise.
