------- Comment From wschm...@us.ibm.com 2016-01-19 11:09 EDT------- The feature is not working. Using
gcc version 5.3.1 20160112 (Ubuntu 5.3.1-5ubuntu3) I attempted to compile a program with -mcpu=power9. Results: ? src gcc -mcpu=power9 -O3 p9-lxvx-stxvx-1.c gcc: error: unrecognized argument in option ?-mcpu=power9? gcc: note: valid arguments to ?-mcpu=? are: 401 403 405 405fp 440 440fp 464 464fp 476 476fp 505 601 602 603 603e 604 604e 620 630 740 7400 7450 750 801 821 823 8540 8548 860 970 G3 G4 G5 a2 cell e300c2 e300c3 e500mc e500mc64 e5500 e6500 ec603e native power3 power4 power5 power5+ power6 power6x power7 power8 powerpc powerpc64 powerpc64le rs64 titan So at least one important patch is missing. The trunk patch to enable -mcpu=power9 is: 2015-11-09 Michael Meissner <meiss...@linux.vnet.ibm.com> Peter Bergner <berg...@vnet.ibm.com> * config/rs6000/rs6000.opt (-mpower9-fusion): Add new switches for ISA 3.0 (power9). (-mpower9-vector): Likewise. (-mpower9-dform): Likewise. (-mpower9-minmax): Likewise. (-mtoc-fusion): Likewise. (-mmodulo): Likewise. (-mfloat128-hardware): Likewise. * config/rs6000/rs6000-cpus.def (ISA_3_0_MASKS_SERVER): Add option mask for ISA 3.0 (power9). (POWERPC_MASKS): Add new ISA 3.0 switches. (power9 cpu): Add power9 cpu. * config/rs6000/rs6000.h (ASM_CPU_POWER9_SPEC): Add support for power9. (ASM_CPU_SPEC): Likewise. (EXTRA_SPECS): Likewise. * config/rs6000/rs6000-opts.h (enum processor_type): Add PROCESSOR_POWER9. * config/rs6000/rs6000.c (power9_cost): Initial cost setup for power9. (rs6000_debug_reg_global): Add support for power9 fusion. (rs6000_setup_reg_addr_masks): Cache mode size. (rs6000_option_override_internal): Until real power9 tuning is added, use -mtune=power8 for -mcpu=power9. (rs6000_setup_reg_addr_masks): Do not allow pre-increment, pre-decrement, or pre-modify on SFmode/DFmode if we allow the use of Altivec registers. (rs6000_option_override_internal): Add support for ISA 3.0 switches. (rs6000_loop_align): Add support for power9 cpu. (rs6000_file_start): Likewise. (rs6000_adjust_cost): Likewise. (rs6000_issue_rate): Likewise. (insn_must_be_first_in_group): Likewise. (insn_must_be_last_in_group): Likewise. (force_new_group): Likewise. (rs6000_register_move_cost): Likewise. (rs6000_opt_masks): Likewise. * config/rs6000/rs6000.md (cpu attribute): Add power9. * config/rs6000/rs6000-tables.opt: Regenerate. * config/rs6000/rs6000-c.c (rs6000_target_modify_macros): Define _ARCH_PWR9 if power9 support is available. * config/rs6000/aix61.h (ASM_CPU_SPEC): Add power9. * config/rs6000/aix53.h (ASM_CPU_SPEC): Likewise. * configure.ac: Determine if the assembler supports the ISA 3.0 instructions. * config.in (HAVE_AS_POWER9): Likewise. * configure: Regenerate. * doc/invoke.texi (RS/6000 and PowerPC Options): Document ISA 3.0 switches. In branches/ibm/gcc-5-branch, I see that this patch is present: 2015-11-20 Michael Meissner <meiss...@linux.vnet.ibm.com> Back port from trunk 2015-11-09 Michael Meissner <meiss...@linux.vnet.ibm.com> Peter Bergner <berg...@vnet.ibm.com> * config/rs6000/rs6000.opt (-mpower9-fusion): Add new switches for etc. So at least this patch was not picked up, which brings into question whether any of the Power9 patches were picked up. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1522410 Title: [Ubuntu 16.04] Enable P9 toolchain To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-5/+bug/1522410/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
