TargetLowering to SelectionDAG so that they have more convenient access to the current DAG, in preparation for the ValueType routines being changed from standalone functions to members of SelectionDAG for the pre-legalize vector type changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37704 91177308-0d34-0410-b5e6-96231b3b80d8 |

To-do ----- * Keep the address of the constant pool in a register instead of forming its address all of the time. * We can fold small constant offsets into the %hi/%lo references to constant pool addresses as well. * When in V9 mode, register allocate %icc[0-3]. * Emit the 'Branch on Integer Register with Prediction' instructions. It's not clear how to write a pattern for this though: float %t1(int %a, int* %p) { %C = seteq int %a, 0 br bool %C, label %T, label %F T: store int 123, int* %p br label %F F: ret float undef } codegens to this: t1: save -96, %o6, %o6 1) subcc %i0, 0, %l0 1) bne .LBBt1_2 ! F nop .LBBt1_1: ! T or %g0, 123, %l0 st %l0, [%i1] .LBBt1_2: ! F restore %g0, %g0, %g0 retl nop 1) should be replaced with a brz in V9 mode. * Same as above, but emit conditional move on register zero (p192) in V9 mode. Testcase: int %t1(int %a, int %b) { %C = seteq int %a, 0 %D = select bool %C, int %a, int %b ret int %D } * Emit MULX/[SU]DIVX instructions in V9 mode instead of fiddling with the Y register, if they are faster. * Codegen bswap(load)/store(bswap) -> load/store ASI * Implement frame pointer elimination, e.g. eliminate save/restore for leaf fns. * Fill delay slots
