GCC alias to function outside of translation unit -AKA- is this even the right tool for the job?

Question

I\'m working with FreeRTOS on an STM32 (Cortex-M3), and using the CMSIS library from ST to bootstrap everything.

The CMSIS library defines the weak symbol SV

Answer 1

Another solution that I gleaned from one of the FreeRTOS examples is to add the following to your FreeRTOSConfig.h ...

/* Definitions that map the FreeRTOS port interrupt handlers to their CMSIS
standard names - or at least those used in the unmodified vector table. */
#define vPortSVCHandler SVC_Handler
#define xPortPendSVHandler PendSV_Handler
#define xPortSysTickHandler SysTick_Handler

The original file is from FreeRTOS/Demo/CORTEX_M0_LPC1114_LPCXpresso/RTOSDemo/Source/FreeRTOSConfig.h which also integrates the CMSIS system clock into the config. A very nice starting point for a CMSIS/FreeRTOS project.
