Hi Uros,
This patch is about to add Rocket Lake to GCC.
Rocket Lake is based on Ice Lake client and minus SGX.
For detailed information, please refer to
https://software.intel.com/content/www/us/en/develop/download/intel-architecture-instruction-set-extensions-programming-reference.html
Bootstrap is ok, and no regressions for i386/x86-64 testsuite.
OK for master?
[PATCH] Add rocketlake to gcc.
gcc/
* common/config/i386/cpuinfo.h
(get_intel_cpu): Handle rocketlake.
* common/config/i386/i386-common.c
(processor_names): Add rocketlake.
(processor_alias_table): Add rocketlake.
* common/config/i386/i386-cpuinfo.h
(processor_subtypes): Add INTEL_COREI7_ROCKETLAKE.
* config.gcc: Add -march=rocketlake.
* config/i386/i386-c.c
(ix86_target_macros_internal): Handle rocketlake.
* config/i386/i386-options.c
(m_ROCKETLAKE) : Define.
(processor_cost_table): Add rocketlake cost.
* config/i386/i386.h
(ix86_size_cost) : Define TARGET_ROCKETLAKE.
(processor_type) : Add PROCESSOR_ROCKETLAKE.
(PTA_ROCKETLAKE): Ditto.
* doc/extend.texi: Add rocketlake.
* doc/invoke.texi: Add rocketlake.
gcc/testsuite/
* gcc.target/i386/funcspec-56.inc: Handle new march.
* g++.target/i386/mv16.C: Handle new march
