2004-06-29Remove files no longer needed. ConstantReader and InstructionReader wereReid Spencer
integrated into Reader. Parser.* was just a bad idea. AnalyzerInternals.h is no longer needed. ReaderPrimitives.h was integrated into Reader.h and Reader.cpp. Dumper.cpp was integrated into Analyzer.cpp. ReaderInternals.h became Reader.h. AnalyzerWrappers.cpp was integerated into ReaderWrappers.cpp git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14496 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-29MAJOR REWRITE.Reid Spencer
- stop passing Buf/BufEnd to every function (now member vars) - internalize things that used to be in a header file that no one else included/needed. - Remove defunct BCR_TRACE lines - Standardize error handling with the PARSE_ERROR macro. - Integrate ConstantReader.cpp and InstructionReader.cpp and reorgnize the definition order so that gcc has a chance at optimizing this module - Standardize case and style of method names. - Eliminate unneeded header files - Prepare for Type != Value (bug122) change by splitting Types into their own data structures. - Implement the BytecodeHandler interface calls. - Provide default implementation of BytecodeHandler interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14494 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-29The code generator should work with unreachable blocks. If not, then thisChris Lattner
is a bug that should be fixed in the code generator, not papered over with the simplifycfg pass. Eliminating this makes bugpoint much more useful git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14477 91177308-0d34-0410-b5e6-96231b3b80d8
