Hi all,
Playing with clock_gettime and uint64_t/int64_t on RPi (ARM), I discovered
uint64_t => double conversion bug :
NOTE: tcc is compiled using --with-libgcc
#include <stdint.h>
#include <stdio.h>
static uint64_t x1 = 123456789;
static uint32_t x2 = 123456789;
int
main()
{
double d1 = (double)x1;
double d2 = (double)x2;
printf("d = %g\n", d1);
printf("%d => %g\n", (uint32_t)x1, d1); // x1 is not 0
printf("%d => %g\n", (uint32_t)x2, d2); // works if x2 is uint32_t
}
$ tcc foo.c && ./a.out
d = 0
123456789 => 0
123456789 => 1.23457e+08
Changing uint64_t to int64_t produces the same bug.
