32-bit x86 MSVC-style exceptions are functionaly similar to 64-bit, but they take no arguments. Instead, they implicitly use the value of EBP passed in by the caller as a pointer to the parent's frame. In LLVM, we can represent this as llvm.frameaddress(1), and feed that into all of our calls to llvm.framerecover. The next steps are: - Add an alloca to the fs:00 linked list of handlers - Add something like llvm.sjlj.lsda or generalize it to store in the alloca - Move state number calculation to WinEHPrepare, arrange for FunctionLoweringInfo to call it - Use the state numbers to insert explicit loads and stores in the IR llvm-svn: 236172 |

Low Level Virtual Machine (LLVM) ================================ This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments. LLVM is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt. Please see the documentation provided in docs/ for further assistance with LLVM, and in particular docs/GettingStarted.rst for getting started with LLVM and docs/README.txt for an overview of LLVM's documentation setup. If you're writing a package for LLVM, see docs/Packaging.rst for our suggestions.
