2005-08-26Make fsel emission work with both the pattern and dag-dag selectors, byChris Lattner
giving it a non-instruction opcode. The dag->dag selector used to not select the operands of the fsel, because it thought that whole tree was already selected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23091 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-26Changes to adjust to new ReplaceAllUsesWith syntax. Change FP_EXTEND toChris Lattner
just return its input, instead of emitting an explicit copy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23088 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-26implement the other half of the select_cc -> fsel lowering, which handlesChris Lattner
when the RHS of the comparison is 0.0. Turn this on by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23083 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-26Change ConstantPoolSDNode to actually hold the Constant itself instead ofChris Lattner
putting it into the constant pool. This allows the isel machinery to create constants that it will end up deciding are not needed, without them ending up in the resultant function constant pool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23081 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-26Fix a huge annoyance: SelectNodeTo took types before the opcode unlikeChris Lattner
every other SD API. Fix it to take the opcode before the types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23079 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23076 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-26add initial support for converting select_cc -> fsel in the legalizerChris Lattner
instead of in the backend. This currently handles fsel cases with registers, but doesn't have the 0.0 and -0.0 optimization enabled yet. Once this is finished, special hack for fp immediates can go away. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23075 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-25Simplify some code. It's not clear why the UDIV expanded sequenceChris Lattner
doesn't work for large uint constants, but we'll keep the current behavior git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23061 91177308-0d34-0410-b5e6-96231b3b80d8
