fix endian issues with condition codes
use memcpy instead of bcopy s/u_int32_t/uint32_t/g fixup endian code to work with solaris hack to make sure htole() works... Nate, have a good idea to fix this? src/arch/sparc/faults.cc: set the reset address to be 40 bits. Makes PC printing easier at least for now. src/arch/sparc/isa/base.isa: fix endian issues with condition codes src/arch/sparc/tlb.hh: add implemented physical addres constants src/arch/sparc/utility.hh: add tlb.hh to utilities src/base/loader/raw_object.cc: add a symbol <filename>_start to the symbol table for binaries files src/base/remote_gdb.cc: use memcpy instead of bcopy src/cpu/exetrace.cc: clean up printing a bit more src/cpu/m5legion_interface.h: add tons to the shared interface src/dev/ethertap.cc: s/u_int32_t/uint32_t/g src/dev/ide_atareg.h: fixup endian code to work with solaris src/dev/pcidev.cc: src/sim/param.hh: hack to make sure htole() works... --HG-- extra : convert_revision : 4579392184b40bcc1062671a953c6595c685e9b2
