2005-08-27Implement PR614:Reid Spencer
These changes modify the makefiles so that the output of flex and bison are placed in the SRC directory, not the OBJ directory. It is intended that they be checked in as any other LLVM source so that platforms without convenient access to flex/bison can be compiled. From now on, if you change a .y or .l file you *must* also commit the generated .cpp and .h files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23115 91177308-0d34-0410-b5e6-96231b3b80d8

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

2005-08-26implement the other half of the select_cc -> fsel lowering, which handlesChris Lattner

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

2005-08-26add 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
