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
Adding IT block in arm mode is ok and ignored. It might be better to fix
the package that way.
