The following is reduced from valgrind package:
$ cat libvex.i
void patchProfInc_AMD64(long *location_of_counter) {
char *p;
long imm64 = (long)location_of_counter;
p[2] = (long)location_of_counter;
imm64 >>= 8;
p[3] = imm64;
imm64 >>= 8;
p[4] = imm64;
imm64 >>= 8;
p[5] = imm64;
imm64 >>= 8;
p[6] = imm64;
imm64 >>= 8;
p[7] = imm64;
imm64 >>= 8;
p[8] = imm64;
imm64 >>= 8;
p[9] = imm64;
}
$ gcc libvex.i -c -O3
