b398b8ff1b Registers: Add a registers.hh file as an ISA switched header. 
This file is for register indices, Num* constants, and register types.
copyRegs and copyMiscRegs were moved to utility.hh and utility.cc.

b0e9654f86 Commit m5threads package. 
This patch adds limited multithreading support in syscall-emulation
mode, by using the clone system call.  The clone system call works
for Alpha, SPARC and x86, and multithreaded applications run
correctly in Alpha and SPARC.

5d029ff11e sycalls: implement mremap() and add DATA flag for getrlimit(). mremap has been tested on Alpha, compiles for the rest but not tested. I don't see why it wouldn't work though. 2009-02-16 17:47:39 -05:00

4514f565e3 syscalls: fix latent brk/obreak bug. 
Bogus calls to ChunkGenerator with negative size were triggering
a new assertion that was added there.
Also did a little renaming and cleanup in the process.

0e6be2a9b1 X86: Add the arch_prctl system call and fix up some microcoding. 
The arch_prctl system call is used to set and get the FS and GS segment
bases. The FS segment is use for TLS, so glibc needs to be able to set it
up.

05c86ec0d7 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.
