Subject: [PATCH 25/32] Initial Granite Rapids D Support

gcc/ChangeLog:

	* common/config/i386/cpuinfo.h
	(get_intel_cpu): Handle Granite Rapids D.
	* common/config/i386/i386-common.cc:
	(processor_alias_table): Add graniterapids-d.
	* common/config/i386/i386-cpuinfo.h
	(enum processor_subtypes): Add INTEL_COREI7_GRANITERAPIDS_D.
	* config.gcc: Add -march=graniterapids-d.
	* config/i386/driver-i386.cc (host_detect_local_cpu):
	Handle graniterapids-d.
	* config/i386/i386.h: (PTA_GRANITERAPIDS_D): New.
	* doc/extend.texi: Add graniterapids-d.
	* doc/invoke.texi: Ditto.

gcc/testsuite/ChangeLog:

	* g++.target/i386/mv16.C: Add graniterapids-d.
	* gcc.target/i386/funcspec-56.inc: Handle new march.
