This patch replaces the SymbolTable class with ValueSymbolTable which does not support types planes. This means that all symbol names in LLVM must now be unique. The patch addresses the necessary changes to deal with this and removes code no longer needed as a result. This completes the bulk of the changes for this PR. Some cleanup patches will follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33918 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-02Changes to support making the shift instructions be true BinaryOperators.Reid Spencer
This feature is needed in order to support shifts of more than 255 bits on large integer types. This changes the syntax for llvm assembly to make shl, ashr and lshr instructions look like a binary operator: shl i32 %X, 1 instead of shl i32 %X, i8 1 Additionally, this should help a few passes perform additional optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33776 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-12For PR1064:Reid Spencer
Implement the arbitrary bit-width integer feature. The feature allows integers of any bitwidth (up to 64) to be defined instead of just 1, 8, 16, 32, and 64 bit integers. This change does several things: 1. Introduces a new Derived Type, IntegerType, to represent the number of bits in an integer. The Type classes SubclassData field is used to store the number of bits. This allows 2^23 bits in an integer type. 2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and 64-bit integers. These are replaced with just IntegerType which is not a primitive any more. 3. Adjust the rest of LLVM to account for this change. Note that while this incremental change lays the foundation for arbitrary bit-width integers, LLVM has not yet been converted to actually deal with them in any significant way. Most optimization passes, for example, will still only deal with the byte-width integer types. Future increments will rectify this situation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33113 91177308-0d34-0410-b5e6-96231b3b80d8

Take an incremental step towards type plane elimination. This change separates types from values in the symbol tables by finally making use of the TypeSymbolTable class. This yields more natural interfaces for dealing with types and unclutters the SymbolTable class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32956 91177308-0d34-0410-b5e6-96231b3b80d8
2006-12-31For PR950:Reid Spencer
Update for signless integer types and parameter attribute implementation. Of significant note: 1. This changes the bytecode format yet again. 2. There are 1/2 as many integer type planes (this is a good thing) 3. GEP indices now use only 1 bit to identify their type which means more GEP instructions won't be relegated to format 0 (size win) 4. Parameter attributes are implemented but currently being stored verbosely for each function type. Some other day this needs to be optimized for size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32783 91177308-0d34-0410-b5e6-96231b3b80d8
