From: Richard Earnshaw Date: Thu, 15 Dec 2016 15:54:53 +0000 (+0000) Subject: [arm] Add isa features to FPU descriptions X-Git-Tag: upstream/12.2.0~42462 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=066416dabcdc6da2596da2c19a9876218c634435;p=platform%2Fupstream%2Fgcc.git [arm] Add isa features to FPU descriptions Similar to the new CPU and architecture ISA feature lists, we now add similar capabilities to each FPU description. We don't use these yet, that will come in later patches. These follow the same style as the newly modified flag sets, but use slightly different defaults that more accurately reflect the ISA specifications. * arm-isa.h (isa_feature): Add bits for VFPv4, FPv5, fp16conv, fP_dbl, fp_d32 and fp_crypto. (ISA_ALL_FPU): Add all the new bits. (ISA_VFPv2, ISA_VFPv3, ISA_VFPv4, ISA_FPv5): New macros. (ISA_FP_ARMv8, ISA_FP_DBL, ISA_FP_D32, ISA_NEON, ISA_CRYPTO): Likewise. * arm-fpus.def: Add ISA features to all FPUs. * arm.h: (arm_fpu_desc): Add new field for ISA bits. * arm.c (all_fpus): Initialize it. * arm-tables.opt: Regenerated.
