v0.04_02 2010-11-13 rurban

fixed -Dt for amd64
do not support MULTIPLICITY without ITHREADS
2.t first enter works again on i386, just not when calling -Dt (probably some register sideeffect).

v0.04_01 2010-11-12 rurban

make amd64 non-threaded work again (old absolute save_plop)
  amd64 r12 unused, only rbx and rcx. maybranch not yet refactored

forgot LOGOP JIT_CHAIN code+root, so the op->next block (true) was never emitted
1st simple profiling looks promising
  See http://blogs.perl.org/users/rurban/2010/11/performance-hacks.html
Try to overcome a missing memalign, by manually aligning the malloced code section, 
  first to pagesize, then to 4096. Fails tests on cygwin, but this has memalign.
implement -Dt debop op tracing within the jit, also -Ds debstack
add my_perl to jit_chain
rename PUSHmov to PUSHrel     
CALL_ABS changes code
add absword and revword macros, use it
add push_imm, push_imm_0 (call any functions)

skip t/3.t on no DEBUGGING perl

check old DEBUG_s..., Perl_ck_warner_d, fix pod
adjust docs (threaded works now)
add explicit abstract and license

TODO first PL_op enter definitevly missing (test 2)

v0.04 2010-11-07 rurban

Fixed i386 1.t + 2.t, threaded and non-threaded
  wrong mov %eax,(%ebx), 
  mov $mem,%ebx (forgot shifting)
  save_plop now without argument
t/3.t maybranch still fails

v0.0302 2010-11-06 rurban

Added memalign, posix_memalign probes. Got failing reports for OpenBSD.

v0.0301 2010-08-28 rurban

Oops, add missing {i386,amd64}.c code to MANIFEST

v0.03 2010-08-09 rurban

Start with amd64/x86_64
Include seperate CPU threaded/non-threaded c files
Create run-jit.c and run-jit.o with .stabs when DEBUGGING
Refactor (maybranch) into jit_chain which runs twice to 
  support branches eventually - ops which do not return op_next
seperate tests, only 1.t works

v0.02 2010-08-06 rurban

Found the i386 call bug with rafl's help - "use stepi"
  - call = e9 (using offsets!), not ff 25 (jmp far).
Fixed call near offsets and PL_op offset without USE_JMP_TABLE.
Fixed initialising PL_op
Small i386 (non-threading) programs do work now

v0.01 2010-08-05 rurban

Non-working version pushed to CPAN being on YAPC::EU. Wanted to show it in a
lightning talk.
