svn commit: r526266 - head/graphics/seexpr/files

New Revision: 526266
URL: https://svnweb.freebsd.org/changeset/ports/526266

Log:
  Our LLVM packages typically built without dump support (which is meant for
  developers, not for actual LLVM-based products), and ``void dump() const''
  sprinkled across LLVM header files are just prototypes.  However, this is
  not the case with ``$localbase/llvm$ver/include/llvm/Support/CFGUpdate.h'',
  where it contains some actual code:
  
      #if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP)
        LLVM_DUMP_METHOD void dump() const { print(dbgs()); }
      #endif
  
  This, in turn, results in the linker failure due to "undefined reference to
  llvm::cfg::Update<llvm::BasicBlock*>::dump() const".  Avoid this by defining
  -DNDEBUG when compiling two files which end up having a reference to dump().
  
  This is a prerequisite to enable building with LLVM backend.
