* Two changes:Reid Spencer2007-01-181-18/+17
| | | | | | | | | 1. Fix logic for executeGEP. Only 32-bit and 64-bit integer types are acceptable as indices. 2. Ensure that all integer cast operations truncate their result to the integer size of the operand. llvm-svn: 33318
* rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger.Chris Lattner2007-01-151-6/+6
| | | | | | | | | rename Type::getIntegralTypeMask to Type::getIntegerTypeMask. This makes naming much more consistent. For example, there are now no longer any instances of IntegerType that are not considered isInteger! :) llvm-svn: 33225

* For PR1064:Reid Spencer2007-01-123-385/+731
| | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 33113

* For PR950:Reid Spencer2006-11-272-36/+181
| | | | | | | | | | The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. llvm-svn: 31931

| | | | | | | | This patch converts the old SHR instruction into two instructions, AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not dependent on the sign of their operands. llvm-svn: 31542

| | | | | | | | Make necessary changes to support DIV -> [SUF]Div. This changes llvm to have three division instructions: signed, unsigned, floating point. The bytecode and assembler are bacwards compatible, however. llvm-svn: 31195
* For PR950:Reid Spencer2006-10-201-2/+2
| | | | | | | | This patch implements the first increment for the Signless Types feature. All changes pertain to removing the ConstantSInt and ConstantUInt classes in favor of just using ConstantInt. llvm-svn: 31063

| | | | | | | | Minor tweaks in public headers and a few .cpp files so that LLVM can build successfully with -pedantic and projects using LLVM with -pedantic don't get warnings from LLVM. There's still more -pedantic warnings to fix. llvm-svn: 28453
