[PATCH 0/7, GCC, V8M] ARMv8-M Security Extensions Hello,
This is a respin of a previous patch series for ARMv8-M Security Extensions. In this version I have removed one patch, rebased the rest and changed some of them. This patch series aims at implementing support for ARMv8-M's Security Extensions. You can find the specification of ARMV8-M Security Extensions in: ARM®v8-M Security Extensions: Requirements on Development Tools (http://infocenter.arm.com/help/topic/com.arm.doc.ecm0359818/index.html). We currently: - do not support passing arguments or returning on the stack for cmse_nonsecure_{call,entry} functions, - only test Security Extensions for -mfpu=fpv5-d16 and fpv5-sp-d16 and only support single and double precision FPU's with d16. Bootstrapped and tested on arm-none-linux-gnueabihf and tested on arm-none-eabi with ARMv8-M Baseline and Mainline targets. Andre Vieira (7): Add support for ARMv8-M's Security Extensions flag and intrinsics Handling ARMv8-M Security Extension's cmse_nonsecure_entry attribute ARMv8-M Security Extension's cmse_nonsecure_entry: __acle_se label and bxns return ARMv8-M Security Extension's cmse_nonsecure_entry: clear registers Handling ARMv8-M Security Extension's cmse_nonsecure_call attribute ARMv8-M Security Extension's cmse_nonsecure_call: use __gnu_cmse_nonsecure_call Added support for ARMV8-M Security Extension cmse_nonsecure_caller intrinsic
