Subject: [PATCH] objtool: remove workaround for unreachable warnings from old GCC
Date: Mon, 27 Aug 2018 12:39:43 +0900 [thread overview]
Message-ID: <1535341183-19994-1-git-send-email-yamada.masahiro@socionext.com> (raw)
Commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6")
bumped the minimum GCC version to 4.6 for all architectures.
This effectively reverts commit da541b20021c ("objtool: Skip
unreachable warnings for GCC 4.4 and older"), which was a workaround
for GCC 4.4 or older.
