Subject: rs6000: Add support for __builtin_cpu_is ("power10")
X-Git-Tag: upstream/12.2.0~15276
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=67161d24f45601e43abea98f2c3d7d7a462b6eab;p=platform%2Fupstream%2Fgcc.git

rs6000: Add support for __builtin_cpu_is ("power10")

Add support for __builtin_cpu_is ("power10").  Also add documentation for
the recently added "arch_3_1" and "mma" __builtin_cpu_supports arguments.

2020-06-25  Peter Bergner  <bergner@linux.ibm.com>

gcc/
	* config/rs6000/rs6000-call.c (cpu_is_info) <power10>: New.
	* doc/extend.texi (PowerPC Built-in Functions): Document power10,
	arch_3_1 and mma.

gcc/testsuite/
	* gcc.target/powerpc/cpu-builtin-1.c: Add tests for power10, arch_3_1
	and mma.
