Bruno Cardoso Lopes 225ca9cdd7 Several changes to Mips backend, experimental fp support being the most ... important. - Cleanup in the Subtarget info with addition of new features, not all support yet, but they allow the future inclusion of features easier. Among new features, we have : Arch family info (mips1, mips2, ...), ABI info (o32, eabi), 64-bit integer and float registers, allegrex vector FPU (VFPU), single float only support. - TargetMachine now detects allegrex core. - Added allegrex (Mips32r2) sext_inreg instructions. - *Added Float Point Instructions*, handling single float only, and aliased accesses for 32-bit FPUs. - Some cleanup in FP instruction formats and FP register classes. - Calling conventions improved to support mips 32-bit EABI. - Added Asm Printer support for fp cond codes. - Added support for sret copy to a return register. - EABI support added into LowerCALL and FORMAL_ARGS. - MipsFunctionInfo now keeps a virtual register per function to track the sret on function entry until function ret. - MipsInstrInfo FP support into methods (isMoveInstr, isLoadFromStackSlot, ...), FP cond codes mapping and initial FP Branch Analysis. - Two new Mips SDNode to handle fp branch and compare instructions : FPBrcond, FPCmp - MipsTargetLowering : handling different FP classes, Allegrex support, sret return copy, no homing location within EABI, non 32-bit stack objects arguments, and asm constraint for float. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53146 91177308-0d34-0410-b5e6-96231b3b80d8		2008-07-05 19:05:21 +00:00
