Asm goto feature was introduces to GCC in order to optimize the support for tracepoints in Linux kernel (it can be used for other things that do nop patching). GCC documentation describes their motivating example here: https://gcc.gnu.org/onlinedocs/gcc-4.8.4/gcc/Extended-Asm.html #define TRACE1(NUM) \ do { \
