2012-12-04Merging MIPS GOT changeset into 3.2 release branch.Pawel Wodnicki
Merging r168471: Mips direct object xgot support This patch provides support for the MIPS relocations: *) R_MIPS_GOT_HI16 *) R_MIPS_GOT_LO16 *) R_MIPS_CALL_HI16 *) R_MIPS_CALL_LO16 These are used for large GOT instruction sequences. Contributer: Jack Carter Merging r168460: [mips] Generate big GOT code. Merging r168458: [mips] Simplify lowering functions in MipsISelLowering.cpp by using the helper functions added in r168456. Merging r168456: [mips] Add helper functions that create nodes for computing address. Merging r168455: [mips] Add command line option "-mxgot". Merging r168453: [mips] When a node which loads from a GOT is created, pass a MachinePointerInfo referring to a GOT entry. Merging r168450: [mips] Add target operand flag enums for big GOT relocations. Merging r168448: Add relocations used for mips big GOT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@169294 91177308-0d34-0410-b5e6-96231b3b80d8

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
