* CASP inline-asm. i.e. if the optimization level is reduced to -O0 the
* CASP restrictions aren't followed and the compiler might end up violation the
* CASP rules. Fix it by explicitly providing ((optimize("-O3"))).
*
* Example:
* ccSPMGzq.s:1648: Error: reg pair must start from even reg at
* operand 1 - `casp x21,x22,x0,x1,[x19]'
