* Adding initial AsmParser implementation for the MBlaze backend. It isWesley Peck2010-10-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | mostly based on the ARM AsmParser at this time and is not particularly functional. Changed the MBlaze data layout from: "E-p:32:32-i8:8:8-i16:16:16-i64:32:32-f64:32:32-v64:32:32-v128:32:32-n32" to: "E-p:32:32:32-i8:8:8-i16:16:16" because the MicroBlaze doesn't have i64, f64, v64, or v128 data types. Cleaned up the MBlaze source code: 1. The floating point register class has been removed. The MicroBlaze does not have floating point registers. Floating point values are simply stored in integer registers. 2. Renaming the CPURegs register class to GPR to reflect the standard naming. 3. Removing a lot of stale code from AsmPrinter after the conversion to InstPrinter. 4. Simplified sign extended loads by marking them as expanded in ISelLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117054 91177308-0d34-0410-b5e6-96231b3b80d8

The MicroBlaze is a highly configurable 32-bit soft-microprocessor for use on Xilinx FPGAs. For more information see: http://www.xilinx.com/tools/microblaze.htm http://en.wikipedia.org/wiki/MicroBlaze The current LLVM MicroBlaze backend generates assembly which can be compiled using the an appropriate binutils assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96969 91177308-0d34-0410-b5e6-96231b3b80d8
