B-C-1.04_32
River stage zero No dependents

Changes for version 1.04_32 - 2009-12-14

  • Only two 5.10 B::C bugs remaining!
  • C.pm: added missing FBM logic to GV >= 5.10 (test 11). Forbid MAGIC on non-magival SVs >= 5.10 (tests 14 + 23). Special PVMG PL_sv_undef string. (namesv problem on 10,14,23)

Changes for version 1.04_31 - 2009-12-14

  • C.pm: fix test 21 on 5.10 "Bad free() ignored". Dynamically allocate CopLABEL
  • Makefile.PL: fix the make depend section > 5.9
  • t/testc.sh: fix -D option

Changes for version 1.04_30 - 2009-12-13

  • 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.

Changes for version 1.04_29 - 2009-12-07

  • 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.

Changes for version 1.04_28 - 2009-12-06

  • 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

Changes for version 1.04_27 - 2009-12-04

  • c.t, cc.t: add failing tests as TODOs

Changes for version 1.04_26 - 2009-12-02

  • C.pm: remove nv->IVX for 5.10 (Can't locate object method "IVX" via package "B::NV"). protect mg->OBJ when SCALAR (Can't call method "save" on unblessed reference). fix NV isa IV, to fix test 23 (Nick Koston). fix CopLABEL for 5.11 (test 21) fix PMOP extflags, esp. for split on >= 5.10 (test 5 + 7) add fbm_compile() to BM::save >= 5.8 (test 11) (Nick Koston)
  • t/c.t, t/testc.sh: added tests 23, 24 (Nick Koston)
  • Bytecode.pm (1.02_04), bytecode.h: store and set PMOP reflags as U32. Fixes tests 2-4,7 Start of backporting Perl 5.6

Changes for version 1.04_25 - 2009-11-30

  • C.pm: fixed IO for 5.11: LINES => IVX. specialize GvLINES = -1 and protect against U32 signed-ness. fixed test 8 main::AUTOLOAD (unoptimized only)
  • t/test.pl: enable -Mblib for all Perl versions. fix 5.6.2 ldopts by explicit checking of (-lperl|CORE\/libperl5). make test works now for 5.6.2

  • t/TESTS, t/testc.sh: added 20 for qr// bug in 5.10
  • t/c.t: remove TODO status from tests 14-16

Changes for version 1.04_23 - 2009-11-22

  • B::Assembler 0.07_03, B::Disassembler 1.05_02, ByteLoader 0.06_03: Added longsize to the bytecode header, just for xcv_depth.
  • B::Debug 1.05_03: Fixes for no threads.

  • Ilya Zakharevich <ilya@math.ohio-state.edu> 1998-04-08 03:21:03 Subject: [PATCH 5.004_64] Cryptic error from B::CC Date: Sat, 11 Apr 1998 19:52:25 -0400 (EDT)
  • Malcolm Beattie <mbeattie@sable.ox.ac.uk> 1998-04-14 16:22:51 [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

  • 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)
  • Malcolm Beattie <mbeattie@sable.ox.ac.uk> 1998-02-25 17:44:34 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.
  • Alpha5 Malcolm Beattie <mbeattie@sable.ox.ac.uk> 1997-12-10 18:33:53
    • 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)
  • a4 Malcolm Beattie <mbeattie@sable.ox.ac.uk> 1997-05-03 14:47:06
    • initial check in of compiler from version Alpha a3 to a4
