1f2e561a6f Use SAHF_SETO_PROFITABLE wherever possible on x86-64, it's faster. This can't 
be the default because some very ancient CPUs don't support LAHF in long mode

2e95c43bf2 Remove the 33-bit addressing hack as it's overly complex for not much gain. 
Rather, use an address override prefix (0x67) though Intel Core optimization
reference guide says to avoid LCP prefixes. In practise, impact on performance
is measurably marginal on e.g. Speedometer tests.

9dfecc4279 Update CPU table to kernel 2.6.17+ code (POWER6, Cell, PA6T). Fix detection 
of the CPU string (separator is actually ','). Fix detection of CPU clock
frequency when it is expressed as a float.

ecf2403c46 ether_unix.cpp somehow pulls something in that needs mem_banks. 
If it isn't compiled in this directory, the wrong config.h is used.

c68e5d916d Working audio output by Daniel Sumorok. 
Not quite the way I wanted to do it but it will do for now.
(on a real Mac, the real audio hardware should be able to pull/grab the data
 from our buffers - an extra thread with its own set of buffers is wasteful!)

87e1518e96 A few fixlets to the SIGSEGV library: 
- Don't export transfer types definitions (formerly used by older API)
- Handle ADD instructions in ix86_skip_instruction() (generated by icc 9.1)
- Use "%p" format for EIP/RIP addresses

c8a273332f Fix for 32-bit x86, was generating setcc CC,%dh instead of %dl. 
i.e. force use of ecx & edx -- though it was fine in 64-bit mode, of course

e07e2196e3 Use new code generator. The gain is only 10%, bottlenecks are elsewhere. 
Optimize Altivec vector splat instructions after Agner's guide.

c306dfc4fd Make VSCR an uint32, don't bother splitting it into NJ, SAT values since 
the gain is almost nil and actually hurts performance in JIT mode.

and termination.

b4768fc62c Run-time assembler fixes: 
- Check for RIP register only in 64-bit mode
- Add missing macros and arguments (BT*im)
- MOVSWQ/MOVZWQ are 64-bit mode instructions only

5d7ef13a9c Fix gen_op_invoke*() for 64-bit offsets on x86-64. Drop CPUPARAM since it's 
now cached to a host register.

7d5898f97a Some minor optimizations: xchg (unused), movdqa in sse2 code. 2006-07-09 12:19:50 +00:00

abc911eaa7 Remove use of global register A0 (now aliased to T0). This makes it possible 
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.

d0a64733ef Use -fno-align-functions to really disable function alignment (a value of 0 
used the default alignment, e.g. 16 bytes on x86_64). This is purely cosmetics
and only helps reading the resulting disassembly.

c677dff47a Add more micro asm optimisations to x86{,-64} (mulhw, mulhwu, slw, srw, cntlzw 
and subf* series). Also now enable the optimzations on x86_64 by default.

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