The LLVM backend builds much faster assuming clang35 and llvm35
are already available. It probably builds on FreeBSD's base clang but
not ports llvm36. In any case, the alternative backend does not
pass the testsuite on FreeBSD (fails at test 825).
The LLVM back is the default backend for DragonFly which allows the
port to build, but it fails the very first test (fails to lock mutex).
There's no need to bump -- for FreeBSD this should package the same
as it did before.
GHDL is the leading VHSIC Hardware Description Language (VHDL) simulator.
Digital and mixed-signal systems such as field-programmable gate arrays
and integrated circuits can be described by VHDL, and VHDL can also be
used as a general purpose parallel programming language. GHDL compiles
VHDL files and creates a binary which simulates the design.
GHDL fully supports IEEE 1076-1987, IEEE 1-76-1993, IEEE 1076-2002
versions of VHDL, and partially IEEE 1076-2008.
