It seems there is a bug in SIGALRM handling when 486 system emulates x86_64
code.
This code:
#include
#include
#include
#include
#include
pthread_t thread1, thread2;
// Signal handler for SIGALRM
void alarm_handler(int sig) {
// Do nothing, just wake up the other thread
}
// Thread
GCC defines __i386__ for i386 and i486, which both lack RDTSC instruction.
The i386 seems to be impossible to distinguish, but i486 can be identified
by checking for undefined __i486__.
