Hey Nick,
This introduced a regression for me with moxie-elf-objcopy.
To reproduce, I feed the assembler this:
.section .text
.global _start
_start:
ldi.l $r0, 0xab6789ab
sta.l 0x0c0ffee0, $r0
sta.b 0xdead, $r0
...like so
$ moxie-elf-as t.s
And the link it...
$ moxie-elf-ld -o t.x a.out
And then...
$ moxie-elf-objdump -h t.x
t.x: file format elf32-bigmoxie
Sections:
Idx Name Size VMA LMA File off Algn
0 .text 00000012 00001000 00001000 00000054 2**0
CONTENTS, ALLOC, LOAD, READONLY, CODE
But I need to change the LMA to 0 for my processor verilog tests so....
$ moxie-elf-objcopy --change-section-lma .text-0x1000 t.x t0.x
moxie-elf-objcopy: t.x: error in private header data: sorry, cannot handle this
file
In this section of elf.c, map->count is 0 in my case...
/* PR 23932. A corrupt input file may contain sections that cannot
be assigned to any segment - because for example they have a
negative size - or segments that do not contain any sections. */
if (map->count == 0)
{
sorry:
bfd_set_error (bfd_error_sorry);
free (sections);
return FALSE;
}
