Subject: Builtins/ARM: __clear_cache doesn't seem to have a consistent prototype, declare
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1058253c364b2c98e6cecfe15d18d3562db245f4;p=clang

Builtins/ARM: __clear_cache doesn't seem to have a consistent prototype, declare
the builtin as void __clear_cache(...) to workaround this, which appears to
match what GCC does.
