I have a program that uses some functions in libgcc (automatically inferred
mult, div, etc..)
My program is divided into a boot sector and an application sector, and i
want those libgcc functions to end up in the boot section.
I know how to map custom made functions to different memory areas, using
e.g:
__attribute__((section(".bootsection"))) int mybootfunc();
and tell the linker script something like:
.bootsection:
{
*(.bootsection)
} > MEM_BOOT_AREA
and if you want to map the functions from e.g. "my_obj.o" file to that same
area you can add it like:
.bootsection:
{
my_obj.o
*(.bootsection)
} > MEM_BOOT_AREA
But when it comes to functions that reside in a library ("libgcc.a") i have
no clue. I have tried to add "libgcc.a" in the same way as the ".o" file
above. The linker does not complain then, but it has no effect.
So the question is:
How do i tell the linker to put the needed libgcc functions in a special
memory section.
I have searched a LOT before asking this, so now i give this list a chance.
(Forgive any newbieness in mailing list etiquette, since I am not used to
mailing lists.)
