2007-09-18C bindings for libLLVMCore.a and libLLVMBitWriter.a.Gordon Henriksen
- The naming prefix is LLVM. - All types are represented using opaque references. - Functions are not named LLVM{Type}{Method}; the names became unreadable goop. Instead, they are named LLVM{ImperativeSentence}. - Where an attribute only appears once in the class hierarchy (e.g., linkage only applies to values; parameter types only apply to function types), the class is omitted from identifiers for brevity. Tastes like methods. - Strings are C strings or string/length tuples on a case-by-case basis. - APIs which give the caller ownership of an object are not mapped (removeFromParent, certain constructor overloads). This keeps keep memory management as simple as possible. For each library with bindings: llvm-c/<LIB>.h - Declares the bindings. lib/<LIB>/<LIB>.cpp - Implements the bindings. So just link with the library of your choice and use the C header instead of the C++ one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42077 91177308-0d34-0410-b5e6-96231b3b80d8

access to bits). Use them in place of float and double interfaces where appropriate. First bits of x86 long double constants handling (untested, probably does not work). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41858 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-06Next round of APFloat changes.Dale Johannesen
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

2007-08-09Patch 10 for long double. Doing constants right needs expanding ConstantFPDale Johannesen
to handle values bigger than double. If we assume host==target and host long double works correctly, this is not too bad, but we don't want to have that limitation longterm. I could implement accepting double constants as long double or something like that, which would lead to incorrect codegen with no errors; the more I think about that the worse it seems. Rather than do such a hack that would be backed out later, I'm settling for giving reasonable error messages, for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40974 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-04This is the patch to provide clean intrinsic function overloading support in ↵Chandler Carruth
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
