Fixes to SPARC syscall emulation mode.
arch/sparc/isa/base.isa: Added a set of abbreviations for the different condition tests. arch/sparc/isa/decoder.isa: Fixes and additions to get syscall emulation closer to working. arch/sparc/isa/formats/branch.isa: Fixed branches so that the immediate version actually uses the immediate value arch/sparc/isa/formats/integerop.isa: Compute the condition codes -before- writing to the state of the machine. arch/sparc/isa/formats/mem.isa: An attempt to fix up the output of the disassembly of loads and stores. arch/sparc/isa/formats/trap.isa: Added code to disassemble a trap instruction. This probably needs to be fixed up so there are immediate and register versions. arch/sparc/isa/operands.isa: Added an R1 operand, and fixed up the numbering arch/sparc/isa_traits.hh: SyscallNumReg is no longer needed, the max number of sources and destinations are fixed up, and the syscall return uses xcc instead of icc. arch/sparc/linux/process.cc: arch/sparc/linux/process.hh: Added a getresuidFunc syscall implementation. This isn't actually used, but I thought it was and will leave it in. arch/sparc/process.cc: arch/sparc/process.hh: Fixed up how the initial stack frame is set up. arch/sparc/regfile.hh: Changed the number of windows from 6 to 32 so we don't have to worry about spill and fill traps for now, and commented out the register file setting itself up. cpu/cpu_exec_context.hh: cpu/exec_context.hh: cpu/simple/cpu.hh: sim/process.cc: sim/process.hh: Changed the syscall mechanism to pass down the syscall number directly. --HG-- extra : convert_revision : 15723b949a0ddb3d24e68c079343b4dba2439f43
