Get X86 to load an elf and start a process for it.
src/arch/x86/SConscript: Add in process source files. src/arch/x86/isa_traits.hh: Replace magic constant numbers with the x86 register names. src/arch/x86/miscregfile.cc: Make clear the miscreg file succeed. There aren't any misc regs, so clearing them is very easy. src/arch/x86/process.hh: An X86 process class. src/base/loader/elf_object.cc: Add in code to recognize x86 as an architecture. src/base/traceflags.py: Add an x86 traceflag src/sim/process.cc: Add in code to create an x86 process. src/arch/x86/intregs.hh: A file which declares names for the integer register indices. src/arch/x86/linux/linux.cc: src/arch/x86/linux/linux.hh: A very simple translation of SPARC's linux.cc and linux.hh. It's probably not correct for x86, but it might not be correct for SPARC either. src/arch/x86/linux/process.cc: src/arch/x86/linux/process.hh: An x86 linux process. The syscall table is split out into it's own file. src/arch/x86/linux/syscalls.cc: The x86 Linux syscall table and the uname function. src/arch/x86/process.cc: The x86 process base class. tests/test-progs/hello/bin/x86/linux/hello: An x86 hello world test binary. --HG-- extra : convert_revision : f22919e010c07aeaf5757dca054d9877a537fd08
