Hi
I wanna do a simple xor of two 64 bit variables as in the following code
fragment:
unsigned long long test0 = 0x8888000000001210LL;
unsigned long long test1 = 0x88111111111100EFLL;
unsigned long long test2;
test2 = test0 | test1;
printf("0x%016x ",test2);
Unfortuantely only the lower 32 bits of the result are correct as the
output shows
0x00000000111112ff
Anyone an idea why the higher 32 bits are not affected by the
bitoperation? I am using gcc (GCC) 3.4.6.
many thanks!
