* Eliminate the remaining uses of getTypeSize. ThisDuncan Sands2007-11-051-6/+8
| | | | | | | | | | | | | | | should only effect x86 when using long double. Now 12/16 bytes are output for long double globals (the exact amount depends on the alignment). This brings globals in line with the rest of LLVM: the space reserved for an object is now always the ABI size. One tricky point is that only 10 bytes should be output for long double if it is a field in a packed struct, which is the reason for the additional argument to EmitGlobalConstant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43688 91177308-0d34-0410-b5e6-96231b3b80d8

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.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41747 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR1064:Reid Spencer2007-01-121-29/+39
| | | | | | | | | | | | | | | | | | | | | | | | 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

* For PR950:Reid Spencer2006-12-311-8/+4
| | | | | | | | | | | | | | | | | | | Three changes: 1. Convert signed integer types to signless versions. 2. Implement the @sext and @zext parameter attributes. Previously the type of an function parameter was used to determine whether it should be sign extended or zero extended before the call. This information is now communicated via the function type's parameter attributes. 3. The interface to LowerCallTo had to be changed in order to accommodate the parameter attribute information. Although it would have been convenient to pass in the FunctionType itself, there isn't always one present in the caller. Consequently, a signedness indication for the result type and for each parameter was provided for in the interface to this method. All implementations were changed to make the adjustment necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32788 91177308-0d34-0410-b5e6-96231b3b80d8
