Changes

-*- change-log -*-
	Started on CPAN with B-C-1.04_12

	* t/testc.sh, t/TESTS: add 44 for weaken import and magic_killbackrefs #72922

1.24	2010-02-15 rurban
	* C.pm: Fixed off by one array access in magic array init (34)
	  - valgrind is your friend.

	* t/modules.t: Added list of to be skipped modules, which cycle endlessly.
	Improve todo message.
	* t/testm.sh: add option -s "install skipped modules"
	* Makefile.PL, cc_harness, perlcc: fix ldflags for ActivePerl 5.10.0

	fail sometimes. Tested ok with strawberry 5.10.1

	* C.pm: fixed evaltry (test 12) mostly, NVX was shared with 2 xpad_cop_seq ints
	  which accidently just worked before 1.17 with %s, but not after changing 
	  to the %g representation.

	  -s a, exitcode 0, ok, no warnings on stderr
	* t/TESTS: added 38, failing on CC (Nick Koston).

	  be sure).
	Removed -qq from 5.6 tests.

1.17	2010-02-03 rurban

	__DATA__ handles work now. Also more Bytecode fixes.
	* t/testplc.sh: Added -S: skip all but -S and Concise
	* Bytecode.pm (1.05): Adapt RV 5.11 change from SV to IV, detect ROK at
	  B::IV::bsave analog to C.pm. Fixes test 16.

	fix for empty options.
	add -sharedxs, -sharedlib; -shared is now for shared linkage, 
	  -sharedlib to create a shared lib (was -shared before but never worked),
	  -sharedxs to also link shared xsubs, no run-time DynaLoader/XSLoader needed.

1.09	2009-12-27 rurban
	* C.pm: Cut down the number of AUTOLOAD'ed optrees, search only on 
	  empty gv->cv (31).
	Added very unsafe -O4/-fcop to eliminate most cops and file + line numbers.

	Adapt coding guidelines, add C and cperl coda. Reformat sources.

	* C.pm: Detect AUTOLOAD and CLONE (test 27 and 31).
	  5.10 is now the best release for unoptimized B::C. 5.8 is faster optimized,
	  but misses some autoloaded xsubs.

1.07	2009-12-19 rurban
	* C.pm: fix fbm_compile (INDEX) for >= 5.10. gv_list is already a pointer.

1.06	2009-12-18 rurban
	Going public on the Perl birthday
	The first public compiler re-release since it was removed from CORE.

	* C.pm: Had to disable -O1 -fcog (pv_copy_on_grow) on 5.10 and higher
	  until I find out how to fool S_unshare_hek_or_pvn. This fixes all C
	  -O1 and -O2 tests. Warn about this.
	Fix wrong RV init on *5.10* for test 29 also, as with 5.11.
	Simplify __DATA__ handling. Warn when -O3 or -fsava-data is missing.

	  B::C 1.06 (1.05 is in 5.8.9)
	  B::CC 1.01

1.04_30 2009-12-13 rurban
	Better 5.6 support, but Bytecode compiler still disabled.
	Not even the Byteloader works for 5.6 assembled code. The Disassembler 
	does not stop at ret. Fixed several C tests.

	* bytecode.pl: renumbering policy: <= 5.6 squeeze, >= 5.8 fixed
	to force exact bytecode numbering as with 5.8.
	Allow float versions, such as 10.001 for subreleases.

	Add perlversion to header.
	Add byteorder check logic.
	
	Added logic to include all possible unsupported ops, all holes.
	bytecode table checked for 5.6.1, 5.6.2, 5.8.0, 5.8.1-5.11
	Note, that I found official and contradicting 5.6.1 releases. 
	ActiveState 5.6.1.626 had no op_children, the unix release tarball 
	with 5.6.1 (called Trial 1) still has it.
	
	* ByteLoader.pm (1.06_06): better bytecode numbering.
	* Asmdata.pm (1.02_02): strict numbering along 5.8.
	Unsupported ops are now also included, with PUT method 0.
	* Assembler.pm (0.07_07): Add perlversion to header
	* Disassembler.pm (1.05_04): Add perlversion to header.
	Print header only for existing.
	* BcVersions/Asm*.pm, BcVersions.pod: added for most versions with the
	CORE compiler.
	* disassemble: Make it work with the older Disassembler.
	Make it work with older bytecode >= 5.8 via Asmdata unsupported ops.
	* i386.xs, jitcompiler.pl: removed (seperate module)
	* bytecode.h, C.xs: Fixed for 5.6, tested with 5.6.1 with MSVC.
	* bytecode.h, byterun.c: add static int force = 0. Override it to 1 to 
	try out executing older bytecodes.

	* C.pm: fix test 16 on 5.10 again, non-threaded only (GVAV magic). 
	  first fix in 1.04_24, broken in 1.04_28. On 5.11 I have a broken 
	  RV handling here.
	Remove version and Regexp::DESTROY from the automatic methods 
	(experimental).
	First attempts with pv and hek consting failed.
	* t/testc.sh, t/testplc.sh: support proper cmdline arguments, add -h for 
	help
	Fixed test 5 by fixing the wrong test.
	* perloptree.pod: renamed from perloptreeguts.pod. Added links.

1.04_29 2009-12-07 rurban
	Disable the Bytecode compiler for 5.6. Fixed besides the __DATA__ handle 
	  (test 15) all remaining 5.8 C bugs.
	* C.pm: assign the PVX of GV also for empty stashes (main::) to avoid 
	  destruction failures at Perl_pad_undef() SvPVX_const(namesv) == '&'. 
	Fixes tests 14 and 23
	* byterun.c: No assert on empty bs_sv, it is &PL_sv_undef.
	Map missing -Dv on 5.6 to -Df i.e. -D256
	Added better debugging output: setter values.
	* STATUS: re-run CORE tests, list cmdlines, update status
	* Disassembler.pm: added gen_header_hash() for gen_header output. 
	  add to documentation.
	* Bytecode.pm: -S uses gen_header_hash for gen_header output.

1.04_28 2009-12-06 rurban
	* C.pm: fix -fcog (Copy on Grow with -O1 and -O2) for >= 5.10 by a new 
	  SVPV. 
	Statically initialize PVs with a union layout trick. Use char* as first 
	  union member. 
	Revert xpvcv+svsect changes to pre-initialize those structs against 
	  gvcv recursion. 
	* t/b.t, t/o.t, t/stash.t: fix tests for 5.6.2
	* bytecode.c: byteorder swab only if same length. 
	1234 => 4321, 12345678 => 87654321.
	Skip a 0x prefix for byteorder in the header. Perl 5.6 had this. 
	* Assembler.pm (0.07_06): 5.6 byteorder fix: until 5.6 the 
	  $Config{byteorder} was falsely dependent on ivsize, we need longsize.
	Add 0x to byteorder in header again, as with 5.6.
	* t/testc.sh: do not run old leftovers. some 5.6 optimizations
	* t/c_o1.t, t/c_o2.t, t/cc_o2.t, t/cc_o2.t: added
	* t/test.pl: support -O1 and -O2
	* broke ByteLoader

1.04_27 2009-12-04 rurban
	* CC.pm (1.02_03): fixed endless loop in optimized sort. The sortcv 
	  cmp needed a return NULL (test 19).
	* c.t, cc.t: add failing tests as TODOs

1.04_26 2009-12-02 rurban
	* C.pm: remove nv->IVX for 5.10 (Can't locate object method "IVX" via 
	  package "B::NV").

    [compiler] CC did "<<" instead of ">>" for right-shift on ints.

Charles Bailey <bailey@newman.upenn.edu>  1998-03-02 01:48:27
    Miscellaneous minor fixes

Spider Boardman <spider@orb.nashua.nh.us>  1998-03-01 02:02:47
    Almost OK: 5.004_61 (threads, perlio)

Andrew Cohen <cohen@andy.bu.edu>  1998-02-27 20:03:29
    Change getc/fread to PerlIO_getc/fread in bytecode.h:
    Subject: [PATCH 5.004_61] bunch of small patches

Nick Ing-Simmons <nick@ing-simmons.net>  1998-02-28 11:31:15
    Missed FREAD in bytecode.h
    Cannot export svref_mutex in non-threaded perl

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-27 18:35:27
    Change FREAD/FGETC to BGET_FREAD/BGET_FGETC to avoid clash with
    preprocessor symbol on Digital UNIX.

Gurusamy Sarathy <gsar@cpan.org>  1998-02-26 03:56:19
    [win32] various cleanups so that B can be built as "just another extension"
     - export symbols needed for building B
     - bset_obj_store() is needed by byterun(), so define it there instead
       of at B.xs, and export it
     - freadpv() is only used in B.xs, so move it there
     - byte*.h are now included by perl.h
     - regenerate embed*.h

Gurusamy Sarathy <gsar@cpan.org>  1998-02-22 02:40:56
    [win32] get compiler building under win32 (needed Makefile.PL
    hacks that could be applicable to other platforms)

    More compiler tweaks.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 18:23:47
    Remove compiler files from their old lib/B locations. The compiler
    now builds by default (without the byteperl executable so far) and
    seems to work at least minimally.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 18:05:33
    Move lib/B/... and lib/[BO].pm over to where they should be,
    under ext/B.
    
Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 17:54:58
    Start getting compiler to work when built with the core.
    [Still won't work as of this change.]

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 16:42:13

	* Merge perlext/Compiler/... into mainline. Some files move to
    ext/B/..., some to lib/B/..., O.pm and B.pm go in lib and some
    move to the base perl directory (e.g. headers). Will need some
    cleaning up before it builds properly, I would guess.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 16:39:38
	* [compiler] Win32 changes from Sarathy, tweaked slightly by me.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-17 17:50:50
	* Assorted changes to the compiler

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-12-17 10:59:40
	* Fix typo in compiler B/C.pm.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-12-10 18:33:53
	Alpha5
	* Start overhauling compiler. It was working at least minimally
    right up until the final tweak of B.xs to add threadsv_names
    at which point building it provokes a seg fault in perl while
    doing the xsubpp :-(.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-09-03 12:31:48
	* Make compiler build/work with devel 5.005

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-07-05 11:58:05  
	* Change %lx to %x in B::CV::save to prevent some CV
    fields becoming 0 in the init section. Add missing
    write_back in B::Stackobj::Padsv::load_double to fix
    test 22 of op/my.t.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-07-05 11:58:05 
	* B::CC::pp_padsv must cope with vivify_ref (5.004)
	  as well as provide_ref (5.003)

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-05-03 14:47:06  
	Alpha 4
	* initial check in of compiler
	from version Alpha a3 to a4
