* [mips] Custom-lower ISD::FRAME_TO_ARGS_OFFSET node.Akira Hatanaka2012-11-07
| | | | | | | Patch by Sasa Stankovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167548 91177308-0d34-0410-b5e6-96231b3b80d8
* [mips] Allow tail-call optimization for vararg functions and functions whichAkira Hatanaka2012-10-30

* [mips] Do not tail-call optimize vararg functions or functions with byvalAkira Hatanaka2012-10-27
| | | | | | | | | | arguments. This is rather conservative and should be fixed later to be more aggressive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166851 91177308-0d34-0410-b5e6-96231b3b80d8

* Add method MipsTargetLowering::passByValArg.Akira Hatanaka2012-10-27
| | | | | | | | | | This method emits nodes for passing byval arguments in registers and stack. This has the same functionality as existing functions PassByValArg64 and WriteByValArg which will be deleted later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166843 91177308-0d34-0410-b5e6-96231b3b80d8
* Add method MipsTargetLowering::copyByValRegs.Akira Hatanaka2012-10-27
| | | | | | | | | | This method copies byval arguments passed in registers onto the stack and has the same functionality as existing functions CopyMips64ByValRegs and ReadByValArg which will be deleted later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166841 91177308-0d34-0410-b5e6-96231b3b80d8

* [mips] Add code to do tail call optimization.Akira Hatanaka2012-10-19
| | | | | | | | | Currently, it is enabled only if option "enable-mips-tail-calls" is given and all of the callee's arguments are passed in registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166342 91177308-0d34-0410-b5e6-96231b3b80d8

* Some ARM implementaions, e.g. A-series, does return stack prediction. That is,Evan Cheng2012-02-28
| | | | | | | | | | | | | | | | | | the processor keeps a return addresses stack (RAS) which stores the address and the instruction execution state of the instruction after a function-call type branch instruction. Calling a "noreturn" function with normal call instructions (e.g. bl) can corrupt RAS and causes 100% return misprediction so LLVM should use a unconditional branch instead. i.e. mov lr, pc b _foo The "mov lr, pc" is issued in order to get proper backtrace. rdar://8979299 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151623 91177308-0d34-0410-b5e6-96231b3b80d8

This patch also removes VSETCC codegen nodes, unifying them with SETCC nodes (codegen was actually often using SETCC for vector SETCC already).
