Subject: Add -fplugin=name.so option to the driver
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9dcbcab85ccca71ccdfa924b6946a0475d93b636;p=clang

Add -fplugin=name.so option to the driver

This translates to -load name.so in the cc1 command. We can't name the driver
option -load, as that means "link against oad", so instead we follow GCC's lead
and name the option -fplugin.
