74c62b9095 - Try to allocate Mac memory only once on 32-bit systems 
- Cap Mac memory to 1023 MB, Apple Personal Diagnostics crashes at 1 GB
- Scratch memory is meant to be addressed from Mac programs too

f446d610f8 Start allocating memory from 0x10000000 with linker scripts since the system 
sometimes has a problem to make a decision when next_address == 0.

NOTE: this makes it possible to allocate up to 1 GB with DIRECT_ADDRESSING

93d918097b Fix vm_acquire_mac() fallback to non 33-bit addressing mode. Support 33-bit 
addressing in REAL_ADDRESSING mode. Only support platforms with proper
linker scripts to map the whole Mac memory from address 0. Warning fix.

NOTE: when compiled with --enable-addressing=real on Linux {x86,x86_64},
you can not address up to 1.5 GB in Basilisk II.

077a232acc Memory allocated through win32 VirtualAlloc() is zero-filled. Likewise for 
memory mmap()'ed with MAP_ANONYMOUS (equivalent to /dev/zero mapping but
faster)

dbc467e316 prefer lower indexes in register allocation, this avoids REX prefixes on 
x86_64 when %r8 - %r15 are used (very light speedup expected)

294664b726 Fix SAHF_SETO_PROFITABLE code for x86-64 platforms. 
This was only an experiment. Improvement was marginal: only +3% on AMD64
(an Athlon 64 3200+). However, it may be interesting to test it on EM64T
(e.g. newer P4s) since an older P3/800, hence in 32-bit mode, got a +15%
improvement in Speedometer 4 benchmarks.

Rationale: lahf/seto sequences avoid load/stores to the stack (push/pop)
and it was thus hoped to be faster.

Anyhow, SAHF_SETO_PROFITABLE can only be enabled manually at this time.
Edit your generated Makefile for testing, but first make sure your CPU
supports lahf in 64-bit mode (lahf_lm flag in /proc/cpuinfo).

3b94dfb1a9 Cosmetics, fix %rh cases in !X86_FLAT_REGISTERS mode, lahf/sahf are now 
valid instructions in long mode (recent enough CPU revisions: lahf_lm).

9d984b3b34 Check whether compiler supports byte bit-fields. If so, we can enable slirp 
emulation code since it pure C+sockets code.

e9e3ad9a4b Further unaligned access fixes on IRIX (Brian J. Johnson). Configury needed

a615a4ac24 Use the most portable POSIX-style non-blocking I/O (O_NONBLOCK) instead of 
BSD-style through FIONBIO. It turns out Tru64 and probably IRIX don't support
the latter when fd is a pipe (slirp case).

e0a966ee15 Code I wrote yesterday was totally broken. It's enough to make sure nPC is 
correctly updated too... Instruction skipper now works on Solaris/SPARC.

99f5dcf66f - Fix SPARC Store Doubleword transfer_size in decoder. 
- In the instruction skipper code, add a huge kludge (trampoline) to forcibly
  zero out %global registers when requested. Otherwise, Solaris/SPARC turned
  out to use %g1 during signal handling, and the zero we could have written
  to there vanished. This assumes [%sp-8] is valid to use (ABI states data
  below %sp is undefined though)

12f103a83a JIT generated code is not guaranteed to be leaf, e.g. there could be a call 
to a generic instruction handler (untranslated code). This caused problems
on MacOS X for Intel where the unaligned stack conditions turned out to be
more visible. Performance loss is really neglectable and this is the right
fix now anyway.

1b99c9501f fix stack alignment (theoritically but it was OK in practise) in generated 
functions, move m68k_compile_execute() to compiler/ dir since it's JIT
generic and it now depends on USE_PUSH_POP (as it should)

641fa2c01e Compiling on Mac OS X 10.2 doesn't define uint8_t using the standard headers. 
Including stdint.h should be safe, but if it clashes, we could put an OS X
specific wrapper around it: #if (defined(__MACH__) && defined(__APPLE__))
