b288f6278e Helper macros to annotate likely branch directions. Colateral effect: this 
also fixes build with GCC 4.1 (ppc-dyngen-ops.cpp) since the branches are
re-ordered in a way there is now only one exit-point in op_jump_next_A0().

d4210ef902 Check whether compiler supports byte bit-fields. If so, we can enable slirp 
emulation code since it pure C+sockets code.

d9fc0aa5ad Look for g++ in /usr/freeware/bin (IRIX/mips for the JIT). Avoid false 
positives in GCC detection, i.e. knowingly cause a syntax error if #error
was not good enough (MIPSpro CC). Fix dyngen g++ version detection if
main compiler is not g++

d19908c9d9 JIT now works on IRIX/mips, you need GCC for the synthetic opcodes: 
CC=cc CXX=CC ./configure --with-dgcc=g++

Also merge MIPSPro optimization flags from Basilisk II tree.

Note that I only verified the emulator works through the testsuite
(all tests passed, including AltiVec emulation)

0f358518df New paranoia checks that better match was SheepShaver is doing with threads 
and sigaltstack(). At least, this time we force use of threads and also
alter r1 to see whether the current threading model relies on it or not.

97726bd1e7 Minor tweaks to support compilation of ether.cpp within MacOS. i.e. mostly 
migrate the Ethernet driver to the MacOS side. This is enabled for
DIRECT_ADDRESSING cases. I didn't want to alter much of ether.cpp (as it
would have required to support that mode). Of course, in REAL_ADDRESSING
mode (the default) and for debugging purposes, the old driver is still
available.

2881c20813 Hopefully fix the remaining issue in the High Resolution Timing support 
code and re-enable it on Linux platforms (they have clock_nanosleep). Why
did I trigger an interrupt inside a held lock? Hmmm, we should probably
add an _ack semaphore like we do e.g. for ethernet.

df960a814e HFS+ is case insensitive (sic!). At least, it pointed out to not remove

fd69df24f3 Re-enable spinlocks on {i386,x86_64} since they are now used only for really 
small atomic operations (add/sub). This implementation should be enough for
that purpose.

08c5f8b713 Improve idle wait mechanism. Now, the emulator thread can be suspended 
(idle_wait) until events arrived and notified through TriggerInterrupt().
i.e. we no longer sleep a fixed amount of time on platforms that support
a thread wait/signal mechanism.

ea42af0568 Consume the packet even if we could not allocate a message block for it in 
the Ethernet interrupt. The BeOS version does that, likewise for MOL. Otherwise,
we end up into an infinite loop reporting the memory allocation failure.

I think this is now the expected behavior as we wouldn't have stats
(num_rx_no_mem) for it if we couldn't get out of the EtherIRQ. ;-) Besides,
the packet will be resent for reliable networks.

38d03d02e9 The alternate stack trick never worked as you can't modify an active stack. 
i.e. it returned EPERM and ran into stack corruption to eventually crash the
emulator. This is noticeable in !hw_mac_cursor_accl mode (e.g. fullscreen DGA).

In order to the sigalstack() to be effective, we must kludge the kernel to
think it's running on another stack. In practise, we provide another stack
for the SIGUSR2 handler. sigusr2_handler_init() fulfills that purpose.

I hope this fixes remaining issues forever. At some point, I had multiple
*_init() handlers in case this is necessary.

a8ba24aecf Use fast spinlocks only for small enough atomic operations. Otherwise, you 
run into some performance problems in e.g. video graphics experience because
of busywaits in the current spin_lock() implementation.

52138d2014 We HAVE_PTHREADS even if we use our own pthreads implementation, this also 
induces availability of locking primitives. I will merge the !HAVE_PTHREADS
case (a la Basilisk II) for EMULATED_PPC when I get back to home.
