2012-08-28Fix mips' long branch pass.Akira Hatanaka
Instructions emitted to compute branch offsets now use immediate operands instead of symbolic labels.

MipsSEFrameLowering. Implement MipsSEFrameLowering::hasReservedCallFrame.

arguments to the stack in MipsISelLowering::LowerCall, use stack pointer and integer offset operands rather than frame object operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161068 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-31Fix type of LUXC1 and SUXC1. These instructions were incorrectly defined asAkira Hatanaka
single-precision load and store. Also avoid selecting LUXC1 and SUXC1 instructions during isel. It is incorrect to map unaligned floating point load/store nodes to these instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161063 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-25Eliminate the stack slot used to save the global base register.Akira Hatanaka
The long branch pass (fixed in r160601) no longer uses the global base register to compute addresses of branch destinations, so it is not necessary to reserve a slot on the stack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160703 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-21Fix Mips long branch pass.Akira Hatanaka
This pass no longer requires that the global pointer value be saved to the stack or register since it uses bal instruction to compute branch distance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160601 91177308-0d34-0410-b5e6-96231b3b80d8
