perl-compiler/Changes

-*- 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

1.43	2013-?? rurban
	5.16 + partial 5.18 support, some more fixes

        * 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
        * 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
	* 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
        Detect "no autovivification;" pragma.
        New -fno-taint, deprecate -fomit_taint
        Fix amagic_generation which was removed with 5.17
	* 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)
        Fixed CvGV_set causing Attempt to free unreferenced scalar in push_begin (42,43)
        Fixed -Do (peek ops)
        Renamed option -f to -F for files.
        Fixed READONLY magic and restricted hashes, issue 98
        Support IsCOW xpvshared strings (>=5.18)
        Fixed wrong xpvshared logic (5.10-5.17), issue 138
        Optimized away 0=default op and gp flags and pointers
        * Assembler (1.11): allow "newpadlx 0"
        * Disassembler (1.12): use B::Concise op_flags and private_flags
	* Stash (1.03): fix compilation for 5.8.8 and below: gv_fetchsv missing
	* t/perldoc.t: perlcc fails with 5.8 because Cwd disturbs the
	  fragile method package finder for File::Spec. Use cc_harness.

1.42	2012-02-01 rurban
        stable up to 5.14

	* C: Improved finding methods in parent classes (Warning: method not found),
	Save @ISA of those child classes.
	Re-implement and simplify my_share_hek, now in terms of share_hek.
	  PL_strtab hack gone. This fixed the shared_hek destruction
	  problems.
	Turn off CvDYNFILE needed since 5.15.4, use static CvFILE. (DateTime)
	* perlcc: perlcc -stash does not hang anymore, renabled t/e_perlcc.t -stash section
	* Stash (1.02): '-xs' does not load B anymore.
	  Now in seperate directory Stash
	* Stash/Stash.xs: new with CvIsXSUB() to get rid of B, polluting the stashes.
	* Stash/Makefile.PL: new
	* Bytecode (1.13): support shared hek (42,43)
	* ByteLoader (0.09), ByteLoader/bytecode.h, bytecode.pl: support shared hek (42,43),
	  added xpvshared
	* t/issue95.t: added, isa methods not found

1.41	2012-01-30 rurban
	* t/modules.t: Fixed syntax error

1.40	2012-01-30 rurban
	static PerlIO Layers (e.g. __DATA__)

	* C: fixed deferred %INC, %INC is now stored and cleaned up at the end.
	Improved __DATA__ handle  as PerlIO layer, PerlIO::scalar now
	  loaded static (test 15).
	Defer eval section after dl_init (e.g. for PerlIO::scalar) (test 15)
	Check for XSLoader now at the very end (test 27)
	Fixed MUTABLE_CV for 5.10.0
	Improved 5.8 method lifting for not-found methods a bit (5.8. perldoc.t)
	* Bytecode: fixed test 22
	  Cannot locate object method "fileno" via package "IO::File"
	* Makefile.PL: readonly $lib fix for MSWin32
	* t/testc.sh: silence ulimit -m warnings + errors

1.39	2012-01-25 rurban
	* C: improved eval AUTOLOAD, avoid some POSIX and Storable .al compile-time
	  side-effects such as creating files and dirs. First try loading
	  .al files, only then eval the dangerous AUTOLOAD.
	* Makefile.PL: typo in -fav-init2 independent_comalloc detection.
	Added LICENSE key, META and the files were not enough to please pause.

1.38	2012-01-24 rurban
	* t/issue93.t: fixed syntax error

1.37	2012-01-24 rurban
	Enabled copy-on-grow strings >= 5.10.
	Save %main:: stashes w/o -fno-stash. Switched to git, added github mirror
	Fixed hashes and share_hek, when mixed compiled and load-time for >5.8.

	Stability: This release is the first which passes almost all tests and
	is used in production with --staticxs -O3, but copy-on-grow hek's and
	further logical improvements (deferred %INC cleanup) fail so far, so it's
	still considered unstable.

	* C: save stashes optionally with -fstash, but only values which are also
	  stashes to avoid a second walker besides savecv, and thus do not
	  walk into unneeded territory; B::STASHGV (46, issue 79)
	New -fno-stash with -O2 to omit stashes which are rarely needed.
	Fixed vulnerability to oCERT-2011-003 style DOS attacks. Do not
	  pre-compute hashes for hv_store(), use fresh random hash seed.
	  But shared_hek() has a limited API which does not allow this.
	UNIVERSAL methods were not correctly stored, which led to method not
	  found at run-time errors.
	New debug option -Dr "runtime" to add debug output to the .c code (as in CC)
	New option -Upackage to skip package, mark_skip()
	Re-implemented sharepvn via share_hek() and SvLEN=0 (issue 71),
	  Special FAKE+READONLY handling: LEN = 0 if pv_copy_on_grow or shared_hek.
	  Fixed !SvIsCOW_shared_hash + FAKE+READONLY conflict (test 13, issue 82).
	  Shared COW hashkeys which are optimized to static const strings
	  may not be marked as IsCOW (remove SVf_FAKE).
	Re-implemented CORE share_hek with hash=0
	  Otherwise shared HEK's (post-5.10) come up with duplicate entries
	  for the same keys; one compile-time created and one run-time created with
	  a different random hash seed. E.g. observed by such warnings
	  "Prototype mismatch: sub bytes::length (_) vs (_)"
	Added Internals::hv_clear_placeholders XS name exception, similar
	  to version:: (issue 83)
	Store CV prototypes, issue 81 and issue 84 for empty () vs NULL prototypes.
	Fixed 5.15.2 hang at hfree_next_entry (issue 78)
	Defer writing of READONLY hash keys since 5.15 (issue 88)
	Enable -fcog copy-on-grow with static strings for >= 5.10
	Improved Errno vs. *main::! and Tie::Hash::NamedCapture vs
	  *main::+  / - logic (issue 90)
	Updated version XS methods, default to noop for (...
	Strip version object overload from XS packages (issue 91), XS needs plain PVs
	Do not initialize CONSTSUB XS methods twice, boot does it for us
	Pass proper cv to XS boot_$name, fixes boot of
	  Tie::Hash::NamedCapture (issue 86)
	Fixed share_hek strings with -O1 (test 13)
	Fixed bootstrapping the XS/core part of attributes,
	  thereby fixed threads tests 41-43.
	Fixed most 5.8.[45] problems by ignoring aelemfast SPECIAL pads.
	Fixed magic -> PTR when SV (>5.6)
	Moved -fsave-sig-hash from -O3 to -O0. You need -fno-save-sig-hash
	  to disable it.
        Removed -fno-stash from -O2, -fno-stash is now the default. You
	  need -fstash to add stashes. It caused not understood problems.
	Fixed saving %SIG signals and more -2 SV magic (issue 92)
	Adjusted IO logic, was erronously skipped (issue 59)
	inc_cleanup: save only those %INC keys which are stored.
	Save ext/mro only if the ext mro methods were loaded, and
	  utf8_heavy.pl similarly.
	Force loading of -u arguments to avoid runtime loading.
	Call boot_core_PerlIO, mro, UNIVERSAL and xsutils.
	Warn on unsavable IO objects from BEGIN blocks.
	  Fixed >&STD... handles (issue 93),
	  i.e. Test::Builder, Test::NoWarnings and parts of the core testing.
	  See http://blogs.perl.org/users/rurban/2012/01/what-to-avoid-in-begin-blocks.html
	Add B::COP::stashflags workaround, >5.15.4 threaded.
	Add fix for lost PL_regex_pad, 5.15 threaded.
	* CC (1.12): allow overriding of -f<opt> B::C flags.
	Skip internal packages with mark_skip (fixes cc_o2 tests).
	Move -ftype-attr from -O2 to -O1.
	Always define int, double and string package versions, parallel to types.
	* Bytecode (1.12): detect Tie::Hash::NamedCapture (issue 90) -
	  works only partially.
	Fixed >&STD... handles (issue 93)
	Support -d debugging without -MOd
	* Stackobj (1.00_03): add UL or L to overlong integers. doubles
	  not yet
	* perlcc (2.13): added options -O[1-4], -u, -U, --Wc, --Wl, --version,
	Keep cfile if output is empty.
	Change -o output C file directory and name with -S or -c:
	  Before in current directory, now in -o directory.
	  Before with input name, now with -o name.
	Add -rpath for all --staticxs libs if supported.
	Changed verbosity levels and output wording.
	* bytecode.pl: added xio_ifp
	* bytecode.h: added BSET_xio_ifp
	* META.yml: remove from MANIFEST and repo, let make dist
	  autogenerate it.
	* t/test.pl, t/TESTS: changed test 46 (Exporter:: and other stashes in
	  %main:: stash) to cover issue 79.
	  use Exporter; print q(ok) if %main::Exporter::
	* t/test.pl: use general comments with optional TODO. Before only TODO
	* t/perldoc.t: fixed for 5.8 with manually adding -uFile::Spec -uIO::Handle
	* t/issue59.t, t/issue81.t, t/issue90.t, t/issue93.t: added

1.36	2011-10-19 rurban
	lexical warnings and more 5.15 fixes
	* C: new B::LEXWARN, fixed representation of lexical warnings which was broken
	  since 8e01d9a6  5.8.9/5.9.4 (issue 76)
	Added section free, use it for lexical cop_warnings (const STRLEN*)
	  (TODO: static PV, HEK + COPs)
	Workaround for utf8::SWASHNEW adjusted to 5.15
	PAD* sv flags changed in 5.15.3
	XSLoader API changed (HEK in caller i.e.): had to add a
	  XSLoader::load_file for [perl #101336] >= 5.15.3,
	  also use mXPUSH for sp instead of 1-arg targ
	Set SvLEN=0 for static PVs to skip sv_clear (problem with 13)
	Handle overlarge negative 64bit ints, double not yet.
	Move -fwarn-sv from -O2 to -O1
	Move -fsave-data from -O3 to -O2
	Compile *main::DATA IO handle automatically (__DATA__), just package __DATA__
	  handles need -fsave-data (15)
	Die with 5.8.4/5.8.5 threaded with split->pushre on invalid
	  pmreplroot. This is a core B::walkoptree bug and can not be
	  easily fixed.
	Tests 15 and 103 do not hang anymore, 15 and 29 pass mostly
	* C.xs: added -Dts support to runloop to check internal compiler
	  problems
	* t/issue76.t: added

1.35	2011-10-02 rurban

	* C: allow debugging without -MOd=C
	improve package_pv detection for methods, two more tests.
	detect previously missing packages within the main sourcefile
	  (50,35,72,73)
	-O1 now includes also -fav-init2 and -fppaddr, which are all
	  stable. -O2 string handling (-fro-inc) still unstable.
	added B::REGEXP::save for \$qr (Encode::Alias), issue 71. Still
	  not fully fixed. Encode::Alias unusable.
	fixed empty HV assertions since 5.15, new HV default keys = 7
	  (3,4,36), but still unsolved 5.15 problem with endless loop in
	  Perl_hfree_next_entry hv.c:1716 (3,4,36)
	workaround 5.15.2 inability to walk with from %INC deleted
	  stashes, also workaround adding already deleted DynaLoader.
	CORE patch [perl #100138] for new 5.15.2-5.15.3 DynaLoader XS_INTERNAL
	  problem required (16,29,44,45). Fixed with 5.15.4
	  0001-Export-DynaLoader-symbols-from-libperl-again.patch
	use proper PL_envgv for *main::ENV which is inited in perl_parse
	  (fixes e.g. CGI apps using run-time values, not compile-time)
	* CC (1.11): allow debugging without -MOd=CC
	Try to jump from last to unknown label, put labels also onto cxstack.
	Fixed cc_last.t test 4, jump out of anonsub, but not across C
	  functions yet (this is disallowed in C, need to split).
	* C.xs: added B::REGEXP::EXTFLAGS (missing from B).
	* perlcc (2.12): omit also inc_version_list dirs from perlcc as
	  leaving them in could lead to unexpected crashes
	* t/cc_last.t: Fixed test 2. This works compiled and uncompiled,
	  but the returned errcode is not compared. Skip if so.
	* t/TESTS: add all 5 possible method/sub calls to test 35 =>01234.
	  See http://blogs.perl.org/users/rurban/2011/06/how-perl-calls-subs-and-methods.html

	* 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.

	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.

	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) == '&'.

	  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.

	* added byteorder to bytecode header.
	* added support for 5.10 (NOT WORKING!), 5.9.5 not tested.
	  up to 5.8.x already in CORE, so disabled.
	  add back support later, when C/CC is improved or more features
	  are added.
	* added type hekindex
	* added c.t and cc.t tests
	* extended bytecode.pl format: added version logic
	  to have strictly consecutive indices

1.04_01 2008-01-15 rurban (never uploaded)
	* first package layout for all now non-CORE packages.

===================================================================

B::C was at 1.05 when removed from core with 5.9.4.

    bytecode.pl:        Exterminate!

Nicholas Clark <nwc10+p5p4@colon.colondot.net>  2007-05-07 14:53:05
    Given that @optype and @specialsv_name are hard coded tables, it seems
    more logical for them to be in B.pm, rather than in the "boilerplate"
    for the machine generated B/Asmdata.pm

    @2452 B.xs had its own code to calculate hash() which differed from
    PERL_HASH in hv.h - so all saved HV's were mangled - including %INC
    which meant that run-time require was re-done.

    @2378 More C.pm tweaks
      Save globs even if we have saved cv itself before - may be imported.

      While we don't save "bootstrap" CV we need to provide a stub,
      so that if we require it later we don't fall through and attempt
      to DynaLoad module again.

      Attempt to save %INC so that "require" does not reload things
      we have compiled-in (does not work right yet - seems to be due
      to PL_incgv being created in perl_parse() current scheme setting
      GvHV() is "better" than saving the glob, but still does not
      work as I expect).

Nick Ing-Simmons <nik@tiuk.ti.com>  1998-11-27 22:10:27
    @2332 Handle INIT list in C.pm
    1. Provide init_av() from B.xs
    2. Export it in B.pm
    3. Use it in C.pm
    Also disable some pruning in savecv() which seems to undo
    my previous patch.
    Experimental feature - save pathnames of .so files in easily
    grep-able form for use in wrapper to feed to linker.

       of at B.xs, and export it
     - freadpv() is only used in B.xs, so move it there

	* 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.
