From: Richard Earnshaw Date: Thu, 15 Dec 2016 16:00:30 +0000 (+0000) Subject: [arm] Use cl_target_options for configuring the active target X-Git-Tag: upstream/12.2.0~42458 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a53613c4ae9ad153ce5d12fdfef413c9e9ae82d6;p=platform%2Fupstream%2Fgcc.git [arm] Use cl_target_options for configuring the active target It now becomes apparent that it would be better to use the the cl_target_options as the basis for calling arm_configure_build_target; it already contains exactly the same fields that we need. I chose not to rewrite the earlier patches as that would make the progression of changes seem less logical than it currently is, with several early changes having no immediate justification. * arm-protos.h (arm_configure_build_target): Change second argument to cl_target_options. * arm.c (arm_configure_build_target): Likewise. (arm_option_restore): Update accordingly. (arm_option_override): Create the target_option_default_node before calling arm_configure_build_target. Use it in call of latter. Resynchronize after all other overrides have been calculated. (arm_valid_target_attribute_tree): Use the target options for reconfiguration. Resynchronize after performing override checks. * arm-c.c (arm_pragma_target_parse): Use target optiosn from cur_tree to reconfigure the build target.
