[Tinycc-devel] Alignment issue

[Daniel Fiala]

Hello.

It seems that alignment in tcc is not working properly. I tried following program:

#include <stdio.h>

static float x[4] = { 1, 2, 3, 4 };

static float y[4] __attribute__((aligned(32))) = { 4, 5, 6, 7 };

int

main(void) {

        fprintf(stderr, "%p\n", x);

        fprintf(stderr, "%p\n", y);

        return 0;

}

I compiled it with tcc 0.9.5 under Ubuntu 14.04 and I got following output:

0x8049544

0x8049554

It looks that address is not aligned. :-(

Alignment to 32bytes is useful for AVX development.

Regards,
