Linux kernels provide an AUXV entry AT_HWCAP that provides most of - this information. However, getting at that entry is not easy this far - away from main. Our options are: start searching from environ, but - that fails as soon as someone does a setenv in between. Read the data - from /proc/self/auxv. Or do the probing ourselves. The only thing - extra that AT_HWCAP gives us is HWCAP_S390_HIGH_GPRS, which indicates - that the kernel saves all 64-bits of the registers around traps while - in 31-bit mode. But this is true of all "recent" kernels (ought to dig - back and see from when this might not be true). */ - -#include <signal.h> - -static volatile sig_atomic_t got_sigill; - -static void sigill_handler(int sig) -{ - got_sigill = 1; -} - static void query_facilities(void) { unsigned long hwcap = qemu_getauxval(AT_HWCAP); |
