* Next round of APFloat changes.Dale Johannesen2007-09-061-11/+16
| | | | | | | | | | | | | | Use APFloat in UpgradeParser and AsmParser. Change all references to ConstantFP to use the APFloat interface rather than double. Remove the ConstantFP double interfaces. Use APFloat functions for constant folding arithmetic and comparisons. (There are still way too many places APFloat is just a wrapper around host float/double, but we're getting there.) llvm-svn: 41747

| | | | | | | | | | | | | | | | | | | | | | | 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 Spencer2006-12-311-96/+95
| | | | | | | | | | | | | This patch replaces signed integer types with signless ones: 1. [US]Byte -> Int8 2. [U]Short -> Int16 3. [U]Int -> Int32 4. [U]Long -> Int64. 5. Removal of isSigned, isUnsigned, getSignedVersion, getUnsignedVersion and other methods related to signedness. In a few places this warranted identifying the signedness information from other sources. llvm-svn: 32785
* For PR950:Reid Spencer2006-12-231-21/+19
| | | | | | | | This patch removes the SetCC instructions and replaces them with the ICmp and FCmp instructions. The SetCondInst instruction has been removed and been replaced with ICmpInst and FCmpInst. llvm-svn: 32751

* For PR950:Reid Spencer2006-11-271-37/+50
| | | | | | | | | | 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
* For PR786:Reid Spencer2006-11-021-2/+2
| | | | | | | | | | Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. llvm-svn: 31380
* For PR950:Reid Spencer2006-10-261-1/+1
| | | | | | | | 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
