Subject: Disable generating movt on FreeBSD.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f1f0c5f32f0b6dc2c6ed3c89545bb79ae00c1fce;p=clang

Disable generating movt on FreeBSD.

It's sort of an hack, but we have no choice.
The linker in the base system doesn't handle that correctly (yet).
Once FreeBSD will import lld, this can be backed out.

Patch by: Andrew Turner!
