-*- change-log -*-
	Started on CPAN with B-C-1.04_12
	The Perl compiler was in CORE from alpha4 until Perl 5.9.4
	and worked quite fine with Perl 5.6 and 5.8

1.45	2014-02-11 rurban
        * C: reset PL_stack_sp on init (was one too far). no effects on code.
        * t/issue281.t: fix wrong test ($[ vs $])

1.44	2014-02-10 rurban
        added adjusted CORE testsuite for 5.14. passes for 5.14.4-nt, not for 5.18.2-nt
	(cPanel code_monkeys)
	still missing in general are:
	  - global destruction (use lexicals!),
	  - attribute handlers,
	  - compile-time perlio layers

        * C: Fix -O3 with ~ and ~~ formatstrings (#277)
	Fix SvLEN and PV ptr for empty shared hash keys (#272)
        Use the natural @dl_modules boot order, just put attributes to the front (#259)
	Store cop_hints to support lexical numeric hints pragmas,
          esp. use bytes and use open attributes
          (fixes #81 #152 #174 #176 #180 #185 #224 #235 #238 #241 #245 #253 #255 #256 #277)
        Skip saving defined(&cv) subs (#96)
        Fix format STDOUT/STDERR (#238, #239, #277, #284, #285, #283)
        Save now empty bodyless subs if they exist, for signal handlers,
          prototypes declarations and cvrefs (#251, #159, #235, #246, #270, #271, #275, #279)
        Fix PVMG PV overwriting the RV, overload sub (#273)
	* CC (1.14): Skip saving non-existing methods analog to B::C 1.43_06 (CC test 50)
	* perlcc (2.17): Accept -A for -DALLOW_PERL_OPTIONS
	* t/testc.sh: Accept -A for -DALLOW_PERL_OPTIONS

1.43	2014-01-15 rurban
	new 5.16, and partial 5.18, 5.20 and windows support.
        Many more fixes and testcases.
        Bytecode is still broken on 5.18, esp non-threaded. 5.20 looks pretty good though.

        * C: Fix -u<module> without file extension.
	With hek do not drop FAKE, only for const pv.
	Fixed $$ ($PID) to be dynamic, issue 108. Thanks to flexvault for reporting this.
        Fixed double precision to 16 digits. The nbody shootout test passes now.
        Fixed refcounts of *ENV, issue 111.
        Fixed wrong boot_ arg for the xs version check with --staticxs
        Better fix for overwriting of @ARGV <O3, test c_argv:1 and c_allow_opts.t:1
        Fixed refinition warnings of XS CONSTSUB. Ignore them as they are
          loaded later.
        Add $dlmodule::VERSION as 2nd arg to boot_$dlmodule resp. $dlmodule::bootstrap
          to get rid of the pesky Invalid version format error in xs_version_bootcheck
          if the $VERSION had already version magic attached. (no testcase, hard to repro)
        perl 5.16.0 shipped a slightly broken B without cop_stashlen. As workaround
          we do not support utf8 stashes nor null bytes in stashes on 5.16.0 threaded.
        Fixed Null COP storage for 5.16 and 5.17
        Fix amagic_generation which was removed with 5.17
        Fix ALLOW_PERL_OPTIONS: add -e behind all processed options, not before
        Fixed HvAUX init. Previously only with magic hashes, now on all OOK hashes (OOK+SHAREKEYS)
          e.g. %warning::Bits
        Added support for new PADLIST type since 5.17.4 (with xpadl_id) and 5.17.6 (without)
        $^X returns now the real executable name, not just perl or perl.exe
        Adjust COW string lengths to hold the COW_REFCNT byte at the end
        Fix unicode string CUR and LEN (#142, #162)
        Fix unicode hashkeys (HEK) mostly (#200), but not yet testc.sh 2001 (compile-time
          stored utf8 heks)
        Save HvTOTALKEYS at run-time as max added to the number of run-time added keys (#178)
        Fix UV uvuformat on 32bit -Duse64bitint (#145)
        op_pmreplstart is now run-time initialized >= 5.10 (#160)
        Fixed special usage of magic vars @-,@+,%+,$-,$! (#90)
        Fixed wrong REGEXP length for compiled QR data (#143)
        Fixed wrong -O3 comparison of strings to numbers (#138,#141, branch new-cog), unified
          PV handling, disabled -fcog replaced by -O3 -fconst-strings
        Fixed NUL-byte handling in strings by using B::SV->PV instead of PVX (#237)
        Storing now bareword filehandles (#148,#149)
        Do not create GvGP at all. This also removes the need for newGP() (Windows/AIX)
        use Config does not include B anymore, Internals::V now in __ANON__ package
        Fixed handling of empty - not successfully autoloaded - CVs (#235, #159, ...)
          by storing the SV and XPVCV but ignoring it and defer to run-time get_cv()
        Unify handling of static and dynamic strings, use ptr_undef throughout instead
          of NULL vs &PL_sv_undef (save_pv_or_rv => savesym, cur, len, pv, static)
        Restore $^H, the numeric value of global warnings flags (#193,#207,#243)
        Restore more missing globals: ${^UNICODE} ${^UTF8LOCALE} $; $\ $, $/ $" $|
          $^A $^L $: $^H $^R $% $- $= if set in a BEGIN block or via cmdline (#256,#231)
        Restore even deprecated vars $] $# $* (#171)
        Fix HvAUX memory corruption, accessing HvAUX beyond HE fields, esp. with threaded perls.
          Initialize now HvAUX backref and mro_meta fields.
        Do not boot internal core XS packages twice, refer to internal XS functions dynamically
          and do not link to them. Fixes fix Windows/AIX with strict linking.
        Defer dynaloaded GvCV initialization after dl_init()
        Fixed storage of non-special lexical warnings (#258 warnsize-i258)
	Fixed storage of shared heks, support IsCOW_hek (i.e. method names)
        Support new ReANY since 5.17.6 (#258 reg_temp_copy)
        Support stash symtab magic for PMf_ONCE m?? and reset (#188)
        Fixed POSIX overflow constants warnings for DBL_MAX,DBL_MIN,LONG_MIN,LONG_MAX (#262)
        Support user-defined static_ext modules, which are already booted from core.
        Add more DynaLoader::dl_debug output (set PERL_DL_DEBUG=1)
        Enforce -ffold on an ucfirst op or $INC{'unicore/To/Title.pl'} (#242)
        Mark empty but overloaded packages (#172). This is merely workaround for reduced testcases.
        Set PadnamelistMAXNAMED(comppad_name) needed since 5.19.3 for eval string (#268)
        Add new option -fno-delete-pkg to control if to ignore compiler-only dependent packages,
          compiler-independent packages are now always saved. Save those package names at Makefile.PL
          in @B::C::Flags::deps.

        * perlcc (2.14): new option --dryrun, -v5 does not -Dsp,-v
         new option -f passthru to C and CC
        * perlcc (2.15): fixed default --spawn: use waitpid which was broken for parallel builds.
        fixed warning Prototype mismatch: sub main::gettimeofday: none vs () at perlcc line 261
        improved --version
        added --perlopts to handle -DALLOW_PERL_OPTIONS
        * perlcc (2.16): changed output name rules:
        Without given output file name we use the name of the input file (in the subdir)
        or with -e a.out resp. a.exe and a randomized intermediate C filename.
        If the input file is an absolute path on non-windows systems use the basename.
	* CC (1.13): Use the B::C integer and double precision logic (ivx, nvx).
        Fixed double precision to 16 digits. The nbody shootout is now 2x faster than perl.
        Added optimizations: -fno-magic, -fno-autovivify, -faelem
        Detect "no autovivification;" pragma.
        New -fno-taint, -fomit_taint is deprecated
        Fix amagic_generation which was removed with 5.17
        Use new perl6 type names: int, num, str. double and string are deprecated.
	* Bytecode (1.14): fixed require and op_first, issue 97
	Fixed regex_pad offset in threaded perls >= 5.11, issue 68.
        New type B::PAD isa B::AV (PADLIST for 5.17.5),
        New bytecodes newpadlx, padl_name, padl_sym (PADLIST for 5.17.5)
