Subject: objdump, readelf: Report errors from CTF archive iteration
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=83d59285d549dab64d1be496408c0e62f30030b4;p=binutils-gdb.git

objdump, readelf: Report errors from CTF archive iteration

We were failing to report errors from ctf_archive_iter, which results in
silent early termination if (for example) one CTF archive member in a
.ctf section is corrupted and cannot be opened.  Report the error in the
usual fashion instead.

binutils/ChangeLog
2020-11-20  Nick Alcock  <nick.alcock@oracle.com>

	* objdump.c (dump_ctf): Report errors from ctf_archive_iter.
	* readelf.c (dump_section_as_ctf): Likewise.
