2004-07-06Fix a bug in the unreachable block elim pass. Dropping all references on aChris Lattner
basic block clear()'s all of the operands lists, including phis. This caused removePredecessor to get confused later. Because of this, we just nuke (without prejudice) PHI nodes in unreachable blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14635 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-05Finalize bytecode dumping. The "handleFinish" method was getting calledReid Spencer
too soon so the function data was not getting dumped (it was generated after the call handleFinish). Also cleaned up the output format for proper indentation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14627 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-04- Changes for bug 122Reid Spencer
- Remove Tabs - Add inserters needed since Value doesn't implement them any more - Move some functions here to avoid cyclic header file dependencies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14618 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-04Adjust the slot machine to handle Types separately from Values. This wasReid Spencer
done by doubling up the data structures so that Type based equivalents are used. A consequence of this is overloading of function members that take a Type* instead of a Value*. Various other cleanups related to Type != Value (bug 122) were also implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14613 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-04Implementation of SlotTable went into header file. Note that this headerReid Spencer
is currently not being used but is retained because it will be the basis for a clean up of the SlotCalculator class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14612 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-04Implement new output functions for types and compacted type planes. AlsoReid Spencer
remove use of Type::TypeTyID and Type::TypeTy since Type no longer inherits Value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14610 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-04Add new methods outputTypes and outputCompactionTypes for handling TypesReid Spencer
separately from Values. This needed for bug 122. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14609 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-04For bug 122:Reid Spencer
Separate Types from Values because Type no longer inherits from Value. The changes for this are too numerous to list. In essence, any data structure that contained a Value was doubled so that Types could be contained similarly. New members include Types, TypeMap, CompactionTypes, and CompactionTypeMap. Functions taking a Value* were overloaded with a variant that takes a Type* that acts on the new data structures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14608 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-04- Type::TypeTyID doesn't exist any more (bug 122)Reid Spencer

2004-07-04- Don't use macros to call the BytecodeHandlerReid Spencer
- Don't use PARSE_ERROR macro unnecessarily (for simple strings) - Add comments before each function - Convert for bug 122 (Type != Value) - Handle new value range on Type::PrimitiveTypeId enumeration by augmenting the reader with a new read_typeid method and sanitizeTypeId method. - Remove BytecodeHandler's default method implementations to header file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14604 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-02Add a trivially simple pass to delete unreachable blocks from the CFG. ThisChris Lattner
pass is required to paper over problems in the code generator (primarily live variables and its clients) which doesn't really have any well defined semantics for unreachable code. The proper solution to this problem is to have instruction selectors not select blocks that are unreachable. Until we have a instruction selection framework available for use, however, we can't expect all instruction selector writers to do this. Until then, this pass should be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14563 91177308-0d34-0410-b5e6-96231b3b80d8
