Summary: CR16 binary output format breaks relocations
Product: binutils
Version: 2.46 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: Jomosoto at proton dot me
Target Milestone: ---
When outputting in binary output format, relocations break
Test case "test.S":
----
.global _start
_start:
nop
_label:
loadb _label, r0
storb r0, 0xFF0000
loadb 0xFF0000, r0
cmpb $0, r0
beq _label

Commands used:
----
as test.S -c -o test.o
ld test.o -o elf.out
ld test.o --oformat=binary -o bin.out
----
"objdump -D elf.out" output:
----

(This is an example based on the instruction variants I saw beeing picked, the
