Subject: Added Cortex-M optimised code to the IAR, GCC and Keil Cortex-M port layers.
X-Git-Tag: V7.3.0~27
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=10659200fba2843014eeb16adb483fbc63c3d9f8;p=freertos

Added Cortex-M optimised code to the IAR, GCC and Keil Cortex-M port layers.
Tested and updated a few Cortex-M projects to use configUSE_PORT_OPTIMISED_TASK_SELECTION set to 1.
