We had various variants of defining dump() functions in LLVM. Normalize them (this should just consistently implement the things discussed in http://lists.llvm.org/pipermail/cfe-dev/2014-January/034323.html For reference: - Public headers should just declare the dump() method but not use LLVM_DUMP_METHOD or #if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP) - The definition of a dump method should look like this: #if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP) LLVM_DUMP_METHOD void MyClass::dump() { // print stuff to dbgs()... } #endif git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@293359 91177308-0d34-0410-b5e6-96231b3b80d8
