da540a74f6 [patch by Mike Sliczniak] 
Here is a patch to allow compiling of SS and B2 with an SDL Framework. You can
get this by downloading from:

http://www.libsdl.org/release/SDL-1.2.13.dmg

Here is how I tested on an intel 32-bit mac with Mac OS X 10.5.6:

SS ./autogen.sh --disable-standalone-gui --enable-vosf --enable-sdl-framework --enable-sdl-framework-prefix=/Users/mzs/Library/Frameworks --enable-sdl-video --disable-sdl-audio --enable-addressing=real
--without-esd --without-gtk --without-mon --without-x

SS /autogen.sh --disable-standalone-gui --enable-vosf --disable-sdl-framework --disable-sdl-video --disable-sdl-audio --enable-addressing=real --without-esd --without-gtk --without-mon --with-x

B2 ./autogen.sh --disable-standalone-gui --enable-vosf --enable-sdl-framework --enable-sdl-framework-prefix=/Users/mzs/Library/Frameworks --enable-sdl-video --enable-sdl-audio --enable-addressing=real --without-esd --without-gtk --without-mon --without-x --enable-jit-compiler

B2 ./autogen.sh --disable-standalone-gui --enable-vosf --disable-sdl-framework --disable-sdl-video --disable-sdl-audio --enable-addressing=real --with-esd --without-gtk --without-mon --with-x --enable-jit-compiler

(esound does not really work on mac, it needs some better coreaudio patches.)

configure.ac for SS has two little additional fixes so that the Cocoa prefs gui
does not get built if you are building for X11 and so that you can use esd, sdl,
or coreaudio for sound.

3e12a80a3b [Patch by Mike Sliczniak] 
I was testing some other SS patches and I noticed that when I ran an X11
build of SS there were not all the video modes I expected in the the
control strip. Mac OS X 10.5 changed the form of the DISPLAY environment
variable. The reason for this is that the DISPLAY variable looks like
this in Leopard:

/tmp/launch-XXXXXX/:0

The Xs are like in mktemp.

ca2b9b5832 [Patch from Mike Sliczniak] 
This first patch gets B2 and SS to build under Leopard and Tiger.

I tested this on a 32-bit intel 10.5.6 mac like so:

B2
./autogen.sh --disable-standalone-gui --enable-vosf --enable-sdl-video --enable-sdl-audio --enable-addressing=real --without-esd --without-gtk --without-mon --without-x

SS
./autogen.sh --disable-standalone-gui --enable-vosf -enable-sdl-video --disable-sdl-audio --enable-addressing=real --without-esd --without-gtk --without-mon --without-x --enable-jit

There is also a little tweak so that you can use sdl audio in SheepShaver when building for Mac OS X.

d6db773362 [patch from Darik Horn <dajhorn@vanadac.com> ] 
Makes SheepShaver compatible with Ubuntu Intrepid and
other distros that bundle the gcc-4.3 compiler.

The patch changes two things:

1. Renames the block_cache where its name collides with its class
definition.

2. Fixes the "explicit template specialization cannot have a storage
class" error in the ppc-dyngen-ops.cpp file.

c23511080e [patch from Kelvin Delbarre] 
Software cursor mode is now supported, although currently the existing hardware
cursor mode is used whenever possible. (Software mode will be used if you are
running with a recent version of SDL's Quartz video driver, since a bug in SDL
1.2.11 and later prevents the hardware cursor from working properly with that
driver.)

In hardware cursor mode, the hot-spot is now determined heuristically. Formerly
it could not be determined and was always (1,1), an annoyance for many cursors
other than the arrow.

In hardware cursor mode, the cursor will now be hidden when requested by the
emulated OS (such as when you are typing in a text field).

In hardware cursor mode, some cursor image formats that the code does not handle
correctly will now be rejected, causing the emulated OS to revert temporarily to
software cursor mode. Formerly you would just end up with random garbage for a
cursor. This typically happened for grayscale or color cursors; rejecting images
with rowBytes != 2 eliminates the worst cases.

d885e5ccf4 [patch from Kelvin Delbarre] SDL's Quartz video implementation maps command 
clicks to right-clicks and option-clicks to middle-clicks, a feature intended
for Mac users with single-button mice who are running SDL-based games that
require a multi-button mouse. This is unhelpful in SheepShaver, where we want
command-clicks and option-clicks to be passed through unchanged to the emulated
Mac OS. We can disable the unwanted behavior by setting an environment variable
SDL_HAS3BUTTONMOUSE intended for this very purpose.

A similar change in main_windows.cpp is NOT required, because only the Quartz
video implementation is involved.

By SDL convention, putenv is used in preference to setenv, although for Unix
platforms it doesn't matter.

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.

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.

would have required to support that mode). Of course, in REAL_ADDRESSING

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.
