Subject: ld: arm32: fix segfault when linking foreign BFDs [PR32870]
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=da82701f3123b6cbf36758c06b00f25b62634d52;p=thirdparty%2Fbinutils-gdb.git

ld: arm32: fix segfault when linking foreign BFDs [PR32870]

PR ld/32870

The linker may occasionally need to process a BFD that is from a
non-Arm architecture.  There will not be any Arm-specific tdata in
that case, so skip such BFDs when looking for iplt information as the
necessary tdata will not be present.
