On aarch64 musl gcc 14.x compiler, trying compiling elfutils 0.192 with
lto option enabled will cause null-dereference error.
Example error message:
...
elf_compress.c: In function 'elf_compress':
elf_compress.c:675:26: error: potential null pointer dereference [-Werror=null-dereference]
675 | shdr->sh_flags |= SHF_COMPRESSED;
| ^
elf_compress_gnu.c: In function 'elf_compress_gnu':
elf_compress_gnu.c:127:25: error: potential null pointer dereference [-Werror=null-dereference]
127 | shdr->sh_size = new_size;
| ^ ^
...
This is a false postive warning but will abort compilation if gcc has
`-Werror` flag. This commit add a patch for this, see the bugzilla
report below.
This commit backports a series of patches to fix some errors.
Add patch:
- 007-add-libeu-symbols-to-libelf.patch
- 008-fix-autoconf-ENABLE_IMA_VERIFICATION.patch
- 009-fix-null-dereference-with-lto.patch
