It is a problem with the inline asm (meant for arm and not thumb mode)
in the source code and seems to be a wide spread problem in existing sr.
I don't think an we can do anything from the tool-chain as such. Problem
is in:
int32_t __TBB_machine_cmpswp4(volatile void *ptr, int32_t value, int32_t
comparand )
{
int32_t oldval, res;
__asm__ __volatile__("dmb ish": : :"memory");
do {
__asm__ __volatile__(
"ldrex %1, [%3]\n"
"mov %0, #0\n"
"cmp %1, %4\n"
"strexeq %0, %5, [%3]\n"
: "=&r" (res), "=&r" (oldval), "+Qo" (*(volatile int32_t*)ptr)
: "r" ((int32_t *)ptr), "Ir" (comparand), "r" (value)
: "cc");
} while (res);
__asm__ __volatile__("dmb ish": : :"memory");
return oldval;
}
