Doing this requires that the driver script tell the parser whether or not the target string is a CPU name or an architecture, but beyond that it is just standard use of the new capabilities. We do, however, now get some error checking if the target isn't recognized, when previously we just ignored unknown targets and hoped that a later pass would pick up on this. * config/arm/arm.h (TARGET_MODE_SPECS): Add additional parameter to call to target_mode_check describing the type of option passed. * common/config/arm/arm-common.c (arm_arch_core_flag): Delete. (arm_target_thumb_only): Use arm_parse_arch_option_name or arm_parse_cpu_option_name to match parameters against list of available targets. * config/arm/parsecpu.awk (gen_comm_data): Don't generate arm_arch_core_flags data structure. * config/arm/arm-cpu_cdata.h: Regenerated. --- gcc/common/config/arm/arm-common.c | 66 ++- gcc/config/arm/arm-cpu-cdata.h | 1052 ------------------------------------ gcc/config/arm/arm.h | 2 +- gcc/config/arm/parsecpu.awk | 38 -- 4 files changed, 48 insertions(+), 1110 deletions(-) diff --git a/gcc/common/config/arm/arm-common.c b/gcc/common/config/arm/arm-common.c index 553123c..930cfb0 100644 --- a/gcc/common/config/arm/arm-common.c +++ b/gcc/common/config/arm/arm-common.c @@ -143,12 +143,6 @@ arm_rewrite_march (int argc, const char **argv) return arm_rewrite_selected_arch (argv[argc - 1]); } -struct arm_arch_core_flag -{ - const char *const name; - const enum isa_feature isa_bits[isa_num_bits]; -}; - #include "config/arm/arm-cpu-cdata.h" /* Scan over a raw feature array BITS checking for BIT being present. @@ -167,26 +161,60 @@ check_isa_bits_for (const enum isa_feature* bits, enum isa_feature bit) /* Called by the driver to check whether the target denoted by current command line options is a Thumb-only target.
