94a9038826 - Remove dead code in readcpu.cpp concerning CONST_JUMP control flow.
- Replace unused fl_compiled with fl_const_jump
- Implement block inlining enabled with USE_INLINING && USE_CHECKSUM_INFO.
  However, this is currently disabled as it doesn't give much and exhibits
  even more a cache/code generation problem with FPU JIT compiled code.
- Actual checksum values are now integral part of a blockinfo regardless
  of USE_CHECKSUM_INFO is set or not. Reduce number of elements in that
  structure and speeds up a little calculation of checksum of chained blocks.
- Don't care about show_checksum() for now.

21909f1eed - Rewrite blockinfo allocator et al. Use a template class so that this
can work with other types related to blockinfos.
- Add new method to compute checksums. This should permit code inlining
  and follow-ups of const_jumps without breaking the lazy cache invalidator.
  aka. chain infos for checksuming. TODO: Incomplete support thus disabled.

518f982775 - CAN_JIT=yes has to be moved into the actual block containing JITSRCS.
- Optimistically reenable gas/x86 assembly optimizations and JIT for FreeBSD
  as it used to work in the past there. If not, beat me.

13e8cb3eec Huh, am I still asleep? Actually use the cpuemuX_nf.cpp pattern rather
than the *.s variant.

75de104c92 - Optimize use of quit_program variable. This is a real boolean for B2.

c492269143 Drop cpuopti on x86 now that we have a fast JIT. I don't want to bother
fixing cpuopti or workarounding code for any known and unknown gcc bug.

98d1246815 - Let fullscreen DGA mode work again, even with a DirectColor visual. In
that case, we do need add it when creating the window otherwise we
  result int a nice BadMatch for X_CreateWindow request. FIXME?
- Fix typo and do enable VOSF in DGA mode, if necessary.

8748b48b7a Disable USE_QUAD_DOUBLE for now and probably for good as (i) the emulator
implementation is not correct, (ii) I don't know of any CPU which
handles this kind of format *natively* with conformance to IEEE.

d7c677d077 - Implement {make,extract}_extended() for USE_QUAD_DOUBLE
- Don't forget to fill in mantissa3 member for USE_QUAD_DOUBLE in
  make_extended_*() but make sure NaN, inf, zeros are handled beforehand

a5ba7ea5ac Don't define USE_LONG_DOUBLE when sizeof(long double) == 16. This still
is not very clean but it should build now. Probably live with USE_LONG_DOUBLE
for any case where native long double exists and sizeof > 8 ?

b765112cf9 Get rid of any "extern inline" bits. Use static inline instead as MIPS
compilers don't really like the former syntax.

ecd3db832e - Rewrite raw_init_cpu() to match more details, from kernel sources.
- Add possibility to tune code alignment to the underlying processor. However,
  this is turned off as I don't see much improvement and align_jumps = 64
  for Athlon looks suspicious to me.
- Remove two extra align_target() that are already covered.
- Remove unused may_trap() predicate.

54ac7a1493 Move -DSAHF_SETO_PROFITABLE down in x86 & gas specific block. Also ensure
SAHF_SETO_PROFITABLE is defined when compiling the JIT. Aka I don't want
to support obsolete and probably bogus code nowadays.

ea98d02ce8 Conditionalize use of pthread_mutexattr_setpshared() as this is an optional
POSIX feature from _POSIX_THREAD_PROCESS_SHARED group. Besides, Ulrich Drepper
mentions "the kernel support for this option wasn't available until 2.5.7.
Future versions of the thread library will support this option."
<http://people.redhat.com/drepper/posix-option-groups.html>

BTW, this nukes a warning when build on FreeBSD 4.6
