__volatile__ is already there. There is also a "memory" modifier in
wld_mmap, and it is missing in wld_mprotect (docs suggest it is the
direct hint for the compiler not to optimize out asm code). But
unfortunately adding it to wld_mprotect does not solve the issue. I will
play more with it and with the other options you suggest.
