2012-10-28This patch is for the implementation of mips16 complex pattern addr16.Reed Kotler
Previously mips16 was sharing the pattern addr which is used for mips32 and mips64. This had a number of problems: 1) Storing and loading byte and halfword quantities for mips16 has particular problems due to the primarily non mips16 nature of SP. When we must load/store byte/halfword stack objects in a function, we must create a mips16 alias register for SP. This functionality is tested in stchar.ll. 2) We need to have an FP register under certain conditions (such as dynamically sized alloca). We use mips16 register S0 for this purpose. In this case, we also use this register when accessing frame objects so this issue also affects the complex pattern addr16. This functionality is tested in alloca16.ll. The Mips16InstrInfo.td has been updated to use addr16 instead of addr. The complex pattern C++ function for addr has been copied to addr16 and updated to reflect the above issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166897 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-17Make sure there is enough room for RA. getStackSize needs to be cleaned up butAkira Hatanaka
we will do that when we implement the full save/restore. Patch by Reed Kotler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164051 91177308-0d34-0410-b5e6-96231b3b80d8

MipsSEFrameLowering. Implement MipsSEFrameLowering::hasReservedCallFrame. Call frames will not be reserved if there is a call with a large call frame or there are variable sized objects on the stack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161090 91177308-0d34-0410-b5e6-96231b3b80d8
