Module Name: src
Committed By: dsl
Date: Wed Feb 5 23:10:41 UTC 2014
Modified Files:
src/sys/arch/amd64/conf: Makefile.amd64
Log Message:
Apparantly clang doesn't like -mno-80387 or -mno-fp-ret-in-387
-msoft-float is equivalent to the former, the latter is probably unlikely
to stop anything not picked up elsewhere.
