[Sending on behalf of Andre Vieira] Hello,
This patch adds the support of the '-mcmse' option to enable ARMv8-M's Security Extensions and supports the following intrinsics: cmse_TT cmse_TT_fptr cmse_TTT cmse_TTT_fptr cmse_TTA cmse_TTA_fptr cmse_TTAT cmse_TTAT_fptr cmse_check_address_range cmse_check_pointed_object cmse_is_nsfptr cmse_nsfptr_create It also defines the mandatory cmse_address_info struct and the __ARM_FEATURE_CMSE macro. See Chapter 4, Sections 5.2, 5.3 and 5.6 of ARM®v8-M Security Extensions: Requirements on Development Tools (http://infocenter.arm.com/help/topic/com.arm.doc.ecm0359818/index.html). *** gcc/ChangeLog *** 2015-10-27 Andre Vieira <andre.simoesdiasvie...@arm.com> Thomas Preud'homme <thomas.preudho...@arm.com> * gcc/config.gcc (extra_headers): Added arm_cmse.h. * gcc/config/arm/arm-arches.def (ARM_ARCH): (armv8-m): Add FL2_CMSE.
