c2566295af Implement a generic setzflg_l() for P4, thus permitting to re-enable 
translation of ADDX/SUBX/BCLR/BTST/BSET/BCHG instructions. i.e. make
it faster. ;-)

0cfa3126b3 Workaround change in flags handling for BSF instruction on Pentium 4. 
i.e. currently disable translation of ADDX/SUBX/B<CHG,CLR,SET,TST> instructions
in that case. That is to say, better (much?) slower than inaccurate. :-(

ee7cea923a Add new run-time assembler derived from GNU lightning. It is suitable for 
both i386 and x86-64 architectures. Still needs some work (see TODO) and
an actual glue to the JIT backend.

Original work is LGPL, but per section 3 of this license, I opt for GPL v2
for Basilisk II purposes.

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.
 2002-10-03 15:05:01 +00:00

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.
 2002-10-03 14:59:35 +00:00
gbeauche
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?
 2002-10-03 14:58:02 +00:00
gbeauche
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.
 2002-10-02 15:55:10 +00:00
gbeauche
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.

98d1246815 - Let fullscreen DGA mode work again, even with a DirectColor visual. In

a5ba7ea5ac Don't define USE_LONG_DOUBLE when sizeof(long double) == 16. This still

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.

- the option "--config FILE" tells B2 to use a different config file

d7c4d7afbf Backout "ignoresegv" support on FreeBSD/x86 for now. Unfortunately, the 
configure script would hang whereas standalone testing will pass all tests.
Any idea why??
- Unix/sigsegv.cpp (ix86_skip_instruction): Add decoder for mozbl instruction.
  (SIGSEGV_REGISTER_FILE [FreeBSD/x86]): Note why we start at EDI offset
  rather than plain sigcontext pointer. i.e. I don't know sigset_t size
  beforehand and don't intend to.

  write-only. Aka. make the page readable too.
