0123552ddc Use extra precision (e.g. long double) for fma operations though this

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.

c5c748f7e2 Some windowed graphics drawing methods cause the snapshot code to fail

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.

1470a8af13 NQD dirty boxes, SDL backend.
This reduces the number of Screen_fault_handler() calls by 80%. i.e. VOSF
is now viable on this turtle MacOS X. Besides, since there is no buffer
comparison, idle sleep can really be effective. SheepShaver in idle mode
on my PBG4 now goes below 8% of CPU resources instead of 70-80% with
bounding boxes based video refreshes.

Caveat: if your program doesn't use standard MacOS routines that call NQD,
then you can expect slower (visual) performance. However, I do think the
new default behavior (VOSF+NQD) is the most common.

3b07ba27e4 Introduce a new video refresh function that uses smaller bounding boxes.
This does not improve graphics performance but helps CPU because it reduces
the number of bytes transfered to actual screen. I saw an improvement by up
to 26% in frameskip 4 800x600x16 but also a hit by 3% with frameskip 0.

The next step is to use NQD bounding boxes to help detecting dirty areas.

So far, this is the best I can do without VOSF working (MacOS X performance
bugs -- pitifully slow Mach syscalls)

5019174a22 SDL Video updates:
- Properly handle migration from "screenmodes" and "windowmodes" to "screen"
- Fix has_mode() logic to really test for actual mode availability. i.e.
  no longer start in large screen mode if user specified a max size.

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.

bc13355b57 Add linker scripts from Basilisk II and make it possible to allocate up to
1 GB of Mac memory. Only tested on Linux/x86_64 so far but with a somewhat
interesting (MacOS, ROM, RAM size) matrix.

XXX: It should be possible to allocate up to 1.5 GB by relocating the ROM
base to something like 0x60800000.
