From: Richard Earnshaw Date: Thu, 15 Dec 2016 15:46:41 +0000 (+0000) Subject: [arm] Use arm_active_target when configuring builtins X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7d0ce9412cf8f961f4e517fef036b2d6bba2dea6;p=gcc.git [arm] Use arm_active_target when configuring builtins This patch uses the new ISA data structure to determine which builtins to add. It entirely eliminates the need for insn_flags to be a global variable, but we're about to delete that in the following patches, so for now we leave it as a global. * arm-builtins.c: Include sbitmap.h. (def_mbuiltin): Change first parameter to a flag bit. Use it to test available features in the current target. (struct builtin_description): Change type of feature field. (IWMMXT_BUILTIN): Use the isa_features types. (IWMMXT2_BUILTIN): Likewise. (IWMMXT_BUILTIN2): Likewise. (IWMMXT2_BUILTIN2): Likewise. (CRC32_BUILTIN): Likewise. (CRYPTO_BUILTIN): Likewise. (iwmmx_builtin): Likewise. (iwmmx2_builtin): Likewise. (arm_iwmmxt_builtin): Check for specific feature bits.
