Dear all,
I am trying to build cross compiler for xc16x. I built successfully
binutils 2.18; gcc 4.0 and newlib 1.18. Everything is fine when
compiling a simple C file without any library call. It is also fine
when making a simple call to printf like printf("Hello world").
However, i got error mes
Dear all,
I am porting GCC to a new target. I don't know how to get attribute of
callee of a call.
I defined a new attribute to assign to a function but when writing for
pattern name "call" or "call_value", I don't know how to know if the
callee is assigned the attribute. As the code for the cal
Hi Jakub,
Thank you for your help.
For direct call, I solved the problem based on your suggestion.
For indirect call, I don't understand much your idea. Could you please
clarify it?

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?

Hi all,
When compiling a C code containing a global declaration like:
char *s = "abc";
The assembly code will be
.section .rodata
.LC0:
.ascii "abc\0"
.section .data
.align 1
_s:
.long .LC0
where the real address of string constant is kept in _s. However,
de. What
is the hook which can help us to do that?
Thank you for any help.

I need to generate multiple load instructions
