Push asm
WebTo work around this we use rdi to store the pointer to the output array, save ebx via push, read from ebx inside the asm block into the array and then restoring ebx to its original state via pop. The push and pop use the full 64-bit rbx version of the register to ensure that the entire register is saved. Webwhere in the last form, asm-qualifiers contains goto (and in the first form, not). The asm keyword is a GNU extension. When writing code that can be compiled with -ansi and the various -std options, use __asm__ instead of asm (see Alternate Keywords).. Qualifiers volatile.
