to cache the CPU context pointer to a register and thus rendering generated
code CPU context independent. Not useful to SheepShaver, but it is for
another project for threads emulation on plain x86-32.
Note: AltiVec performance may drop a little on x86 but this will be restored
(and even improved) in the future.
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.
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.
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.
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.
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.
- 'boot' 3: set boot stack pointer only once at the correct place
- 'gpch' 750: fix FE0A opcode replacement (selector #$0a is virt2phys on pgidx)
- 'gpch' 750: remove bogus patch for SonyVars
- Mark patches "9.0" verified accordingly vs. 8.6
be useful to fix a bug in the AppleShare extension (see DRVR .AFPTranslator
in Basilisk II)
Unrelated improvement: call sheepshaver_cpu::get_resource() directly, don't
get it through another global function.
