* C bindings for libLLVMCore.a and libLLVMBitWriter.a.Gordon Henriksen2007-09-182-0/+373
| | | | | | | | | | | | | | | | | | | | | | | | | | | - 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

* Fix for PR1633: Verifier doesn't fully verify GC intrinsicsGordon Henriksen2007-09-171-0/+36
| | | | | | | | | | | | | | | LLVM now enforces the following prototypes for the write barriers: <ty>* @llvm.gcread(<ty2>*, <ty>**) void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**) And for @llvm.gcroot, the first stack slot is verified to be an alloca or a bitcast of an alloca. Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42051 91177308-0d34-0410-b5e6-96231b3b80d8
