2009-03-07The _exit syscall is used for both thread termination in NPTL applications,pbrook
and process termination in legacy applications. Try to guess which we want based on the presence of multiple threads. Also implement locking when modifying the CPU list.

2009-02-28Flush stdout after printing usage()blueswir1
Fixes qemu-arm|grep cpu - with _exit() getting output from qemu --help is a bit random. Since no atexit() handlers are registered for user mode emulation, just use exit() instead.

2009-01-30linux-user: identify running binary in /proc/self/exeaurel32
Some applications like to test /proc/self/exe to find out who they are. Fake the result of readlink() for them. Use realpath() to return full path to binary (which the links /proc/self/exe are) Signed-off-by: Riku Voipio <riku.voipio@iki.fi> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6485 c046a42c-6fe2-441c-8c8c-71466251a162

2008-11-18x86: Debug register emulation (Jan Kiszka)aliguori
Built on top of previously enhanced breakpoint/watchpoint support, this patch adds full debug register emulation for the x86 architecture. Many corner cases were considered, and the result was successfully tested inside a Linux guest with gdb, but I won't be surprised if one or two scenarios still behave differently in reality.
