New Revision: 210388
URL: http://svn.freebsd.org/changeset/base/210388
Log:
Build clang libraries by default with -fno-exceptions and with
-fno-rtti. The clang libaries that really use exceptions and virtual
functions can enable LLVM_REQUIRES_EH and LLVM_REQUIRES_RTTI
respectively. This saves space on the resulting binaries and follows
what's being done upstream.
