From 4f430e9ab56443e822171b7881f4d50475dbaf25 Mon Sep 17 00:00:00 2001 From: Korey Sewell Date: Mon, 10 Apr 2006 12:23:17 -0400 Subject: Finally MIPS does hello world! arch/mips/isa/bitfields.isa: add RS_SRL bitfield ...these must be set to 0 for a SRL instruction arch/mips/isa/decoder.isa: Make unimplemented instructions Fail instead of just Warn Edits to SRA & SRAV instructions Implement CFC1 instructions Unaligned Memory Access Support (Maybe Not fully functional yet) Enforce a more strict decode policy (in terms of different bitfields set to 0 on certain instructions) arch/mips/isa/formats/branch.isa: Fix disassembly arch/mips/isa/formats/int.isa: Add sign extend Immediate and zero extend Immediate to Int class. Probably a bit unnecessary in the long run since these manipulations could be done in the actually instruction instead of keep a int value arch/mips/isa/formats/mem.isa: Comment/Remove out split-memory access code... revisit this after SimpleCPU works arch/mips/isa/formats/unimp.isa: Add inst2string function to Unimplemented panic. PRints out the instruction binary to help in debuggin arch/mips/isa/formats/unknown.isa: define inst2string function , use in unknown disassembly and panic function arch/mips/isa/operands.isa: Make "Mem" default to a unsigned word since this is MIPS32 arch/mips/isa_traits.hh: change return values to 32 instead of 64 arch/mips/linux_process.cc: assign some syscalls to the right functions cpu/static_inst.hh: more debug functions for MIPS (these will be move to the mips directory soon) mem/page_table.cc: mem/page_table.hh: toward a better implementation for unaligned memory access mem/request.hh: NO ALIGN FAULT flag added to support unaligned memory access sim/syscall_emul.cc: additional SyscallVerbose comments --HG-- extra : convert_revision : 1987d80c9f4ede507f1f0148435e0bee97d2428c --- arch/mips/linux_process.cc | 28 +++++++++++++--------------- 1 file changed, 13 insertions(+), 15 deletions(-) (limited to 'arch/mips/linux_process.cc') diff --git a/arch/mips/linux_process.cc b/arch/mips/linux_process.cc index 92a79cfd1..2d02b09e1 100644 --- a/arch/mips/linux_process.cc +++ b/arch/mips/linux_process.cc @@ -132,7 +132,7 @@ SyscallDesc MipsLinuxProcess::syscallDescs[] = { /* 14 */ SyscallDesc("mknod", unimplementedFunc), /* 15 */ SyscallDesc("chmod", chmodFunc), /* 16 */ SyscallDesc("lchown", chownFunc), -
