Subject: [PATCH 0/3] objtool: GCC 8 support
Date: Wed, 9 May 2018 22:39:13 -0500 [thread overview]
Message-ID: <cover.1525923412.git.jpoimboe@redhat.com> (raw)
Now that GCC 8 is out, several people have complained about a bunch of
objtool warnings. These patches fix all known warnings.
Patch 1 is a repost of a previous fix -- unrelated to GCC 8, but a
prereq for the following two patches.
Patch 2 fixes the vast majority of the warnings, caused by GCC 8's new
usage of "cold" subfunctions for unlikely text.
Patch 3 fixes a few more warnings, related to switch tables.
Josh Poimboeuf (3):
objtool: Fix "noreturn" detection for recursive sibling calls
objtool: Support GCC 8 cold subfunctions
objtool: Support GCC 8 switch tables
