* Now that tblgen can handle matching implicit defs of instructionsChris Lattner2010-03-194-131/+104
| | | | | | | | | | | | | | | | | | | | | | | | | to input patterns, we can fix X86ISD::CMP and X86ISD::BT as taking two inputs (which have to be the same type) and *returning an i32*. This is how the SDNodes get made in the graph, but we weren't able to model it this way due to deficiencies in the pattern language. Now we can change things like this: def UCOM_FpIr80: FpI_<(outs), (ins RFP80:$lhs, RFP80:$rhs), CompareFP, - [(X86cmp RFP80:$lhs, RFP80:$rhs), - (implicit EFLAGS)]>; // CC = ST(0) cmp ST(i) + [(set EFLAGS, (X86cmp RFP80:$lhs, RFP80:$rhs))]>; and fix terrible crimes like this: -def : Pat<(parallel (X86cmp GR8:$src1, 0), (implicit EFLAGS)), +def : Pat<(X86cmp GR8:$src1, 0), (TEST8rr GR8:$src1, GR8:$src1)>; This relies on matching the result of TEST8rr (which is EFLAGS, which is an implicit def) to the result of X86cmp, an i32. llvm-svn: 98903

* Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() toBob Wilson2010-03-182-6/+14
| | | | | | | | | | | | | | | | | always create a new jump table. The intention was to avoid merging jump tables in SelectionDAGBuilder, and to wait for the branch folding pass to merge tables. Unfortunately, the same getJumpTableIndex() method is also used to merge tables in branch folding, so as a result of this change branch tables are never merged. Worse, the branch folding code is expecting getJumpTableIndex to always return the index of an existing table, but with this change, it never does so. In at least some cases, e.g., pr6543, this creates references to non-existent tables. I've fixed the problem by adding a new createJumpTableIndex function, which will always create a new table, and I've changed getJumpTableIndex to only look at existing tables. llvm-svn: 98845
