9f6edc436b Fix mismerge from kpx branch 2006-07-04 08:54:53 +00:00

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.

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

(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.

aka avoid use of (possibly broken) GCC intrinsics. Add some SSE2 optimizations.

shows more than 1 GFlops performance!

Since pthread_suspend_np() is not available to Linux (but NetBSD 2.0), thread
suspend is implemented likewise to boehm-gc.

663facbf97 Fix native Linux/ppc with recent enough glibc that supports TLS; r2 is used
in that case. Tell me if I broke other arches, e.g. r13 is no longer saved
in Video and Ethernet stubs, though it seems to be OK.

Colateral feature: SheepShaver should now run on Linux/ppc64 with relevant
32-bit runtime. Native Linux/ppc64 support is harder as low mem globals are
32-bit in mind and e.g. the TLS register there is %r13, %r2 is the TOC
(PowerOpen/AIX ABI)
