2007-01-03Restore previous behavior of defaulting to ZEXT. This works around twoReid Spencer
things: (1) preventing PR1071 and (2) working around missing parameter attributes for bool type. (2) will be fixed shortly. When PR1071 is fixed, this patch should be undone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32831 91177308-0d34-0410-b5e6-96231b3b80d8
2007-01-03Two changes:Reid Spencer
1. Switch expression and cases are compared signed and are sign extended. 2. For function results needing extended, do SIGN_EXTEND if the SExtAttribute is set and ZERO_EXTEND if the ZExtAttribute is set, otherwise just let the Legalizer do ANY_EXTEND. This fixes the recent regression in kimwitu++ and probably the llvm-gcc bootstrap issue we had today. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32830 91177308-0d34-0410-b5e6-96231b3b80d8

2006-12-31For PR950:Reid Spencer
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
2006-12-23For PR950:Reid Spencer
This patch removes the SetCC instructions and replaces them with the ICmp and FCmp instructions. The SetCondInst instruction has been removed and been replaced with ICmpInst and FCmpInst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32751 91177308-0d34-0410-b5e6-96231b3b80d8

2006-12-14Fix a long-standing spiller bug:Evan Cheng
If a spillslot value is available in a register, and there is a noop copy that targets that register, the spiller correctly decide not to invalidate the spillslot register. However, even though the noop copy does not clobbers the value. It does start a new intersecting live range. That means the spillslot register is available for use but should not be reused for a two-address instruction modref operand which would clobber the new live range. When we remove the noop copy, update the available information by clearing the canClobber bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32576 91177308-0d34-0410-b5e6-96231b3b80d8
