2007-02-19Implement support for non-standard integer bit widths of any size. TheReid Spencer
rules alignment is to pick the alignment that corresponds to the smallest specified alignment that is larger than the bit width of the type or the largest specified integer alignment if none are larger than the bitwidth of the type. For the byte size, the size returned is the next larger multiple of the alignment for that type (using the above rule). This patch also changes bit widths from "short" to "uint32_t" to ensure there are enough bits to specify any bit width that LLVM can handle (currently 2^23); 16-bits isn't enough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34431 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-05Although targets are not required to support integers > 64bits, TargetDataReid Spencer
must in order for backends that do want to support large integer types to be able to function. Consequently, don't assert if the bitwidth > 64 bits when computing the size and alignment. Instead, compute the size by rounding up to the next even number of bytes for the size. Compute the alignment as the same as the LongABIAlignment. These provide reasonable defaults that the target can override. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33943 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

2006-12-31For PR950:Reid Spencer
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
