b662e6acec Add linker script for FreeBSD 5.3 (and probably newer). Verified to allocate 
up to 1 GB of Mac RAM in both REAL_ADDRESSING and DIRECT_ADDRESSING modes.

NetBSD 2.0 can use the Linux linker script. However, I could not verify 1G
support since my installation does not permit this.

449c6496ff Link with AppKit framework on MacOS X. This should enable X11 builds when 
there is no SDL available (suggested by Dara Hazeghi)

7ee9cb43dc Relocate MacOS X executable to 0x78048000 akin to linker scripts on Linux 
arches. This probably already worked in the past but I have just verified
that Basilisk II works with up to 1 GB of Mac RAM in DIRECT_ADDRESSING or
REAL_ADDRESSING mode.

BTW, a quick Speedometer 4 CPU performance test showed a +15% speed increase
in real addressing mode vs. direct addressing. x86 arches don't benefit much
from that mode since they support complex address modes already (beyond plain
load/store).

TODO: check on MacOS X for Intel so that to reduce the test to darwin*:*)

74c62b9095 - Try to allocate Mac memory only once on 32-bit systems

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.

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).

d475faf4ba Copy constants to 32-bit addressable data pool. This fixes -pie builds on 
x86_64: program resides above 32-bit barrier and JIT generated code wants
(knowingly) to access globals directly.

a615a4ac24 Use the most portable POSIX-style non-blocking I/O (O_NONBLOCK) instead of

the latter when fd is a pipe (slirp case).

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)

f32e053178 Apply the no-stack-frame optimization in op_invoke_*() to MacOS X for Intel 
templates. This avoids mis-aligninment of the stack, and useless reservation
of space on it for function args. Indeed, we now pre-allocate 16 stack-slots
in op_execute() for this purpose.
