s390/bug: add entry size to the __bug_table section (e21f8baf) · Commits · 戴 / test

Change the __EMIT_BUG inline assembly to emit mergeable __bug_table entries with type @progbits and specify the size of each entry. The entry size is encoded sh_entsize field of the section definition, it allows to identify which struct bug_entry to use to decode the entries. This will be needed for the objtool support.
