pbrook c276471991 The _exit syscall is used for both thread termination in NPTL applications,
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.

Use macros to avoid #ifdefs on debugging code.

This patch doesn't try to merge logging macros from different files,

further cleanup can unify the debugging macros on a common header, later

aliguori a1d1bb3101 Refactor and enhance break/watchpoint API (Jan Kiszka)
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.

First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.

Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

aliguori 6b9175478e Refactor translation block CPU state handling (Jan Kiszka)
This patch refactors the way the CPU state is handled that is associated
with a TB. The basic motivation is to move more arch specific code out
of generic files. Specifically the long #ifdef clutter in tb_find_fast()
has to be overcome in order to avoid duplicating it for the gdb
watchpoint fixes (patch "Restore pc on watchpoint hits").

aurel32 970d622e8a target-alpha: fix cmpbge instruction
The cmpbge instruction should compare all 8 bytes of one 64-bit value with
another.  However, we were looping with a < 7 condition which was skipping
the top byte.  So if we were doing a compare where the top byte was
important, we could get the wrong result (this notably breaks the strlen()
function with certain sized strings).

aurel32 57a92c8e36 target-alpha: fix locked loads/stores
Fix reading of cpu_lock in gen_qemu_stql_c, original patch from Laurent
Desnogues.

A new flag was added to gen_store_mem to allocate local temps instead
of temps;  this flag should be set when the tcg_gen_qemu_store callback
uses brcond before using the temps or else liveness analysis will get
rid of the temps.

This also adds lock printing in cpu_dump_state which can help
debug.

aurel32 1304ca878a target-alpha: Fix ret instruction
Hopefully pine doesn't corrupt this patch, I've had problems recently.

For an alpha "ret" instruction, of the type
     ret $26

The return was being ignored.  This is because in translate.c
register $26 (the return address) was being over-written with the current
PC before it could be jumped to.  Thus the ret was ignored.

This patch just re-orders things so the return address is processed before
it is over-written with the current PC.

aurel32 29d26d20e5 fix alpha cmovxx instruction
The CMOV instruction is defined by the alpha manual as:

CMOVxx Ra.rq,Rb.rq,Rc.wq !Operate format
CMOVxx Ra.rq,#b.ib,Rc.wq !Operate format

Operation:
IF TEST(Rav, Condition_based_on_Opcode) THEN
Rc ← Rbv

The current qemu behavior inverses Ra and Rb.  This is fixed by this
patch.
