Dear all,
When porting GCC on xc16x, I met a problem with a constant string. The
following is the C code:
#include "stdio.h"
int main () {
printf ("c\n");
}
And the following is the generated assembly:
.xc16x
.section .rodata
.LC0:
.ascii "c\0"
.

How can I turn this optimization off?

Use -fno-builtin-printf.

Use -fno-builtin-printf.
I'm curious, it's obviously a correct optimization, so why
would you want to turn if off?
