* More cleanups for CellSPU:Scott Michel2008-01-3018-3868/+4951
| | | | | | | | | | - Expand tabs... (poss 80-col violations, will get them later...) - Consolidate logic for SelectDFormAddr and SelectDForm2Addr into a single function, simplifying maintenance. Also reduced custom instruction generation for SPUvecinsert/INSERT_MASK. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46544 91177308-0d34-0410-b5e6-96231b3b80d8

This is a short term solution that is necessary only because llvm, for now, cannot model i128 nor call's with multiple results.

| | | | | | | | | | | | type that matters but the operand type. This fixes 2008-01-08-IllegalCMP.ll which crashed with the new legalize infrastructure because SETCC with result type i8 and operand type i64 was being custom expanded by the X86 backend.

* Overhaul Cell SPU's addressing mode internals so that there are nowScott Michel2008-01-2914-874/+645
| | | | | | | | | | | | | | | only two addressing mode nodes, SPUaform and SPUindirect (vice the three previous ones, SPUaform, SPUdform and SPUxform). This improves code somewhat because we now avoid using reg+reg addressing when it can be avoided. It also simplifies the address selection logic, which was the main point for doing this. Also, for various global variables that would be loaded using SPU's A-form addressing, prefer D-form offs[reg] addressing, keeping the base in a register if the variable is used more than once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46483 91177308-0d34-0410-b5e6-96231b3b80d8
