Author: dim Date: Sun Feb 23 23:23:01 2014 New Revision: 262415 URL: http://svnweb.freebsd.org/changeset/base/262415 Log: Pull in r201994 from upstream llvm trunk (by Benjamin Kramer): SPARC: Implement TRAP lowering. Matches what GCC emits. This lets clang emit "ta 5" for trap instructions on sparc64, instead of emitting a call to abort(), making it possible to link the kernel.
