We had various users reporting issues about instructions in their application
were not supported by valgrind. The users were able to isolate the failing
instructions and provided the following simple cases:
int main()
{
asm ("mtspr 3,0");
}
int main()
{
asm ("xvnegsp 33,34");
}
There was another user who's application was trying to read the time
base register. Unfortunately, valgrind only returned 32-bits not the
required 64-bits. The simple test case is:
#include <stdio.h>
#include <sys/platform/ppc.h>
int main(int argc, char** argv)
{
uint64_t tb = __ppc_get_timebase();
printf("timebase = %lx\n", tb);
sleep(15);
tb = __ppc_get_timebase();
printf("timebase = %lx\n", tb);
return 0;
}
