arm: Make 'conflicting CPU architectures' error message more user-friendly
Checks
Commit Message
Error messages such as "conflicting CPU architectures 10/16" are not
very to understand, so this patch replaces the numbers with the
description they actually mean:
"conflicting CPU architectures ARM v7E-M vs Pre v4"
2023-09-01 Christophe Lyon <christophe.lyon@linaro.org>
bfd/
* elf32-arm.c (tag_cpu_arch_combine): Add name_table parameter and
use it.
(elf32_arm_merge_eabi_attributes): Update call to
tag_cpu_arch_combine.
ld/
* testsuite/ld-arm/attr-merge-9.out: Update expected error
message.
* testsuite/ld-arm/attr-merge-arch-2.d: Likewise.
