crash/gdb-7.6.patch
Dave Anderson e770735200 Fix for an ARM64 gcc-10 compilation error. Without the patch, the 
build of the embedded gdb module fails with an error message that
indicates "multiple definition of 'tdesc_aarch64'".

Raw Blame History

# When this file is updated in an existing source tree, it gets re-applied
# during the next build using "patch -N --fuzz=0", which ignores patches
# that have already been applied. However, if a gdb file has been modified
# multiple times, the subsequent patching may fail to recognize that a
# given patch has been previously applied, and will attempt to re-apply it.
# To prevent any uninintended consequences, this file also acts as a
# shell script that can restore any gdb file to its original state prior
# to all subsequent patch applications.
# The gdb-7.6-ppc64le-support.patch will have modified both files below
# during the initial build, so continue previous behavior.
