Subject: [microblaze-uclinux] microblaze-uclinux-elf2flt bug with static
initializers
Date: Mon, 22 Jun 2009 16:05:07 +0200

Hello,

We've encountered a problem with static initializers in the
microblaze-uclinux-elf2flt tool from PetaLinux 0.20 Build -rc1 050607,
svn revision 5150.

In the following code snippet two arrays w_0[] and r_0[] reside in .bss,
and two other arrays w[] and r[] in .data:

int w_0; /* .bss */
int r_0; /* .bss */

int *w[] = {&w_0}; /* .data */
int *r[] = {&r_0}; /* .data */

The arrays from .data are initialized with pointers to the arrays
in .bss. However, the r[] array gets initialized wrongly as can be seen
by running the attached C program. Essentially, elf2flt seems to assign
a wrong pointer to an array element with a static initializer, if the
pointer refers to a symbol from a different ELF section.

Is there any chance this issue can be solved in the elf2flt? Thanks in
advance!

Best regards,
Andrei Terechko
