Subject: gas: Fix uninitialized c64 member of aarch64_fix struct
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4a282ed903fcce7e98d09af474eca5e2b7c209f4;p=thirdparty%2Fbinutils-gdb.git

gas: Fix uninitialized c64 member of aarch64_fix struct

The c64 flag in the aarch64_fix struct was missing an initialization.
This was causing Morello relocations to be spuriously inserted, even
when not targeting C64.

This patch fixes the issue by initializing the flag to false.
