Subject: [PATCH 01/16] s390/boot: fix section name escaping
Date: Mon, 12 Aug 2019 14:50:34 -0700	[thread overview]
Message-ID: <20190812215052.71840-1-ndesaulniers@google.com> (raw)

GCC unescapes escaped string section names while Clang does not. Because
__section uses the `#` stringification operator for the section name, it
doesn't need to be escaped.

This antipattern was found with:
$ grep -e __section\(\" -e __section__\(\" -r
