Subject: [clang-cl] Alias /Wall to -Weverything
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ca47944a2c9f7c7fb66f0c812c28c16e2f3286fb;p=clang

[clang-cl] Alias /Wall to -Weverything

cl interprets this option to mean enable every supported warning, which
is what Clang's -Weverything flag does.
