7efab4276f Improve FPU emulation accurracy. However, PPC_ENABLE_FPU_EXCEPTIONS is still 
set to 0 until generated code is optimized enough (current slow down factor
is 3x vs. previous core, expectations are about 50% slower FP code).

The main benefit is exception bits are accurate. All glibc test-fenv,
test-arith{,f}, test-double, test-float pass on ppc, and mostly on x86_64
with gcc 4.0.1. Yes, this is also compiler dependent.

FIXME: find a real Mac application that depends on precise FPSCR bits... I
think I don't want to care optimizing yet until someone shows me a real world
application.

3f3891ab31 Move up NATMEM_OFFSET to 0x11000000. This is arbitrarily determined to be 
the base of the largest free block. Turns out SDL libraries are loaded around
0x10000000 so we have some luck here.

757f849ad0 Optimize generated code to NQD & CheckLoad functions. They don't call into 
68k or MacOS code, so they don't need to be a termination point. i.e. don't
split into two basic blocks and thus avoid a full hash search.

Also add missing NQD_unknown_hook NativeOp from previous commit.

484469962b Don't let SDL catch SIGINT and SIGTERM signals. This is not suitable for 
SheepShaver since we are typically translating SDL_QUIT events to PowerOff()
on MacOS side. And, if MacOS is not fully booted, it's not really convenient
to shut it down, even with ctrl-C. i.e. you had to kill -9 it.

0af4721cb6 Don't read from 0xf8000090 during MacOS (8.5, 9.0) installation. Is this an 
OpenFirmware check for OldWorld 604-based machines?

XXX I have code pending that makes it possible to use PowerMac ID #3035 and
model 510 (PowerMac G3 Series). However, I have a regression with one of my
MacOS 8.6 disks. This is non-standard anyway since it was installed from the
iMac DV 8.6 discs ("yellow" not generic) with MOL -- SheepShaver can't cope
with it.

So I am not surprised it breaks. Otherwise, 8.5 -> 9.0.4 were fine with it.

BTW, the "regression" is Native Resource Manager is not installed and the
boot gets mad later. FWIW, it's the same as for MacOS 9.1. A resource is
very likely not loaded.

6eacaf2e82 Fix asm clobbers for newer gcc 4.0.1, don't use -msse to enable xmm clobbers

MMX/SSE code without explicit intrinsics use of vectorization, we know
those register won't be clobbered outside of the __asm__ code. So, it's safe
as is (we could also remove all sse/mmx clobbers).

ec8661f431 Fix a damn silly bug. On some occasions, we could have spcflags() set to 
EXEC_RETURN | HANDLE_INTERRUPT. And then, we handled the interrupt, but
EXEC_RETURN was set so we returned very quickly without completing the
interrupt routine. As a side effect, this occasionnaly hung the emulator
most likely with {ethernet,audio}-based applications that trigger a lot
of interrupts.

The fix is to always honour EXEC_RETURN flag at first, of course.

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.
