Subject: rs6000: Delete FP_ISA3
X-Git-Tag: basepoints/gcc-14~6178
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a05aac0a130cd4e09530ebeb6beae4e5495ad6bc;p=thirdparty%2Fgcc.git

rs6000: Delete FP_ISA3

FP_ISA3 is exactly the same as SFDF, just a less obvious name.  So,
let's delete it.

2022-06-09  Segher Boessenkool  <segher@kernel.crashing.org>

	* config/rs6000/rs6000.md (FP_ISA3): Delete.
	(float<QHI:mode><FP_ISA3:mode>2): Rename to...
	(float<QHI:mode><SFDF:mode>2): ... this.  Adjust.
	(*float<QHI:mode><FP_ISA3:mode>2_internal): Rename to...
	(*float<QHI:mode><SFDF:mode>2_internal): ... this.  Adjust.
	(floatuns<QHI:mode><FP_ISA3:mode>2): Rename to...
	(floatuns<QHI:mode><SFDF:mode>2): ... this.  Adjust.
	(*floatuns<QHI:mode><FP_ISA3:mode>2_internal): Rename to...
	(*floatuns<QHI:mode><SFDF:mode>2_internal): ... this.  Adjust.
