Subject: gas: scfi: add missing ginsn-cofi-1 testcase files
X-Git-Url: https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff_plain;h=48942a586ebc056bd059d3f63a5eed3a2fa46ab3;hp=7586594c484bbc2a1fb472b988c7e9cbc08c8416
gas: scfi: add missing ginsn-cofi-1 testcase files
Previous commit a58dc5427f0 intended to bring the following two commits
from master branch:
91cdbed4d7b gas: scfi: untraceable control flow should be a hard error
16cbeae1b27 x86: testsuite: scfi: adjust COFI testcase
But missed adding the testcase files. Fix the failure by adding the
missing files.
gas/testsuite/
* gas/scfi/x86_64/ginsn-cofi-1.l: New test.
* gas/scfi/x86_64/ginsn-cofi-1.s: Likewise.
