big-endian file format

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




With help from this list, I have built big-endian tools -- gcc, as, ld -- for our processor, running on a little-endian Intel platform. For a simple program:

char g1 = 0x17;
short g2 = 0x27;
int g4 = 0x47;
long long g8 = 0x87;

int main(void)
{
  PASS(g1);
  PASS(g2);
  PASS(g4);
  PASS(g8);
  DONE(0);
  return 0;
}

Dump of object file .data section with od:

0000600 17 00 27 00 47 00 00 00 87 00 00 00 00 00 00 00

I see that the g1, g2, g4, g8 constants are laid out as little-endian numbers (i.e., LSB first) in the object file. Is this to be expected when the tools run on a little-endian platform, or does this mean something is broken?

Thanks.
