2cb7e02c9e Some instructions assume offsets are only 1-byte long. I don't think this 
is 100% correct. Therefore, insert some asserts so that would fail.

aa6b264d21 Add raw_emit_nop_filler() with more efficient no-op fillers stolen from 
GNU binutils 2.12.90.0.15. Speed bump is marginal (less than 6%). Make it
default though, that's conditionalized by tune_nop_fillers constant.

8de7ad1091 - Turn on runtime detection of loop and jump alignment as Aranym people 
reported they got some improvement with it and larger loops. Small
  loops are an issue for now until unrolling is implemented for DBcc.
- Const jumps are identified in readcpu. I don't want to duplicate code
  uselessly. Rather, it's the JIT job to know whether we are doing block
  inlining and un-marking those instructions as end-of-block.

a60c6da7c3 Turn on block inlining so that people could test this feature and report 
if they do gain something or renders JIT less stable.

724516511a Do translate BSR.L, we don't have any issue with that even if we are 
doing block inlining since we have a complete chain of information about
the blocks to checksum.

e11dd3d375 Do translate FMUL instructions, the core needs to be fixed and this is 
not translation of that instruction. I believe this is related to some
misgeneration of FPU core sequence and allocation of FP registers?

e9584dbcc1 Add PROFILE_UNTRANSLATED_INSNS information. Interestingly, the following 
are the bottleneck now: DIVS, BSR.L (why isn't it translated yet?),
bit-field instructions (I need to self-motivate enough for that), and
A-Traps.

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

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

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

  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.
