Indeed, it seems that gcc allows the use of SP in inline asm.
I could do one of the three:
1. keep the SP register forbidden.
2. have the SP as one exception.
3. redo the patch to prevent only the use of the frame pointer.
Honestly I cannot come to a conclusion on which is the best option. Do you have an opinion on this?
