* Long live the exception handling!Anton Korobeynikov2007-07-142-4/+6
| | | | | | | | | | | | | | | | This patch fills the last necessary bits to enable exceptions handling in LLVM. Currently only on x86-32/linux. In fact, this patch adds necessary intrinsics (and their lowering) which represent really weird target-specific gcc builtins used inside unwinder. After corresponding llvm-gcc patch will land (easy) exceptions should be more or less workable. However, exceptions handling support should not be thought as 'finished': I expect many small and not so small glitches everywhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@39855 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR950:Reid Spencer2006-12-312-19/+20
| | | | | | | | | | | | | | | | | | | 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
