21c4e9da5b Building on GCC 2 causes errors:
../uae_cpu/gencpu.c: In function `void gen_opcode(long unsigned int)':
../uae_cpu/gencpu.c:874: conversion from `unsigned int' to `enum wordsizes'
../uae_cpu/gencpu.c:875: conversion from `unsigned int' to `enum amodes'
due to mismatching of types in struct instr and types in function prototypes.
However, this only started happening recently and I don't know why :-(

1cbb3395d2 1) Publish methods for clearing and blackening the bitmap
2) Always do the calculations for a possibly scaled view.
Even if we prevent the user from changing the view size,
the Monitors control panel in the emulator may still try to
select a resolution which is too large for the screen,
and thus the window will have to be reduced to fit,
and thus the screen and bitmap co-ords may not match

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.

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
than the *.s variant.

75de104c92 - Optimize use of quit_program variable. This is a real boolean for B2.
- Remove unused/dead code concerning surroundings of (debugging).
- m68k_compile_execute() is generated and optimized code now.

bdf9d76bb8 - #include "flags_x86.h" here to get NATICE_CC_?? helper macros
- Add raw_cmp_b_mi() and raw_call_m_indexed() for generated
  m68k_compile_execute() function

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.

JIT compiler. ;-) BTW, also fixes some valgrind warnings.
