commit 356a4d73be3575298af0179b8e5197fb5643e65d
Author: Michael Meissner <meissner@linux.ibm.com>
Date: Thu Feb 15 19:25:54 2024 -0500
Add -mcpu=power11 and -mcpu=future support.
2024-02-15 Michael Meissner <meissner@linux.ibm.com>
gcc/
* config.gcc (powerpc*-*-*, rs6000-*-*): Add support for power11 and
future processors.
* config/rs6000/rs6000-c.cc (rs6000_target_modify_macros): Define
_ARCH_PWR11 if -mcpu=power11 and _ARCH_PWR_FUTURE if -mcpu=future.
* config/rs6000/rs6000-cpus.def (ISA_POWER11_MASKS_SERVER): Add support
for -mcpu=power11.
(ISA_FUTURE_MASKS_SERVER): Add support for -mcpu=future.
(POWERPC_MASKS): Add support for -mcpu=power11 and -mcpu=future.
(power11 cpu): Add power11 cpu.
(future cpu): Add future cpu.
* config/rs6000/rs6000-opts.h (PROCESSOR_POWER11): New macro.
(PROCESSOR_FUTURE): Likewise.
* config/rs6000/rs6000-tables.opt: Regenerate.
* config/rs6000/rs6000.cc (rs6000_machine_from_flags): If -mcpu=power11,
emit .machine power11. If -mcpu=future emit .machine future.
(rs6000_opt_masks): Add support for power11 and future ISA bits.
* config/rs6000/rs6000.h (ASM_CPU_SPEC): Pass -mfuture to the assembler
if -mcpu=future. Pass -mpower11 to the assembler if -mcpu=power11.
* config/rs6000/rs6000.opt (-mpower11): New internal ISA bit for
power11 cpu.
(-mfuture): New internal ISA bit for future cpu.
* doc/invoke.texi (PowerPC options): Document -mcpu=future and
-mcpu=power11.
