* Add lengthof and endof templates that hide a lot of sizeof computations.Owen Anderson2007-09-073-16/+12
| | | | | | | Patch by Sterling Stein! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41758 91177308-0d34-0410-b5e6-96231b3b80d8
* Next round of APFloat changes.Dale Johannesen2007-09-061-16/+17
| | | | | | | | | | | | | | | 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.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41747 91177308-0d34-0410-b5e6-96231b3b80d8

* This is the patch to provide clean intrinsic function overloading support in ↵Chandler Carruth2007-08-041-2/+2
| | | | | | | | | LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40807 91177308-0d34-0410-b5e6-96231b3b80d8
