From e53993efae201a6a65164a299e5305894ff1cb84 Mon Sep 17 00:00:00 2001 From: Richard Earnshaw Date: Fri, 16 Jun 2017 21:03:30 +0000 Subject: [PATCH] [arm] Use standard option parsing code for detecting Now that the standard CPU and architecture option parsing code is available in the driver we can use the main CPU and architecture data tables for driving the automatic enabling of Thumb code. 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.
