Subject: Use '--readnever' when invoking GDB from gcore.in
X-Git-Tag: gdb-8.3-release~137
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8a6a85134d78531c6adb72a888844f7cfa3a5c56;p=external%2Fbinutils.git

Use '--readnever' when invoking GDB from gcore.in

Back when I proposed the '--readnever' feature, I somehow forgot or
decided not to include the bits related to gcore.in in the original
patch.  This patch finally updates the gcore script to invoke GDB
using '--readnever'.

We've been carrying this patch on Fedora GDB for quite some time, and
as expected the corefiles generated by gcore on Fedora don't have
problems, which I think is the best indicator that the it's safe to
generate corefiles using '--readnever'.
