B-C-1.04_14
River stage zero No dependents

Changes for version 1.04_14 - 2008-03-24

  • Fixes some 1.04_13 +x executable permissions in docs. Windows habits.

Changes for version 1.04_13 - 2008-03-24

  • Fixed B::C pv init in 5.10. Forgot refcnt and flags.
  • Added "Other perl to exe compilers" section to perlcompile.pod. This is even a FAQ.
  • Added the NOTES to perlcompile.pod
  • Added temp. perloptreeguts.pod. In work, also at the wiki.
  • Fixed Bytecode op_pmflags assertions.
  • Added orangesect for enough regexp space in RE's sv_any. Engine not initialized though.
  • Hangs in C/CC executables at an op_free(PL_main_root) trying to free the static op structsm because the earlier op_seq -1 hack is gone now, and opt_static was replaced by opt_latefree. Set now opt_latefree = 1. This fixed tests 1 and 13. Slowly making progress step by step.

Changes for version 1.04_12 - 2008-03-16

  • Fixed bug #40435 CC: Can't locate object method "_save_common_middle" via package "B::FAKEOP"
  • move tests from [bc]*.t into shared TESTS file.

  • make C and CC less verbose, honor -v, -q ignored.

Changes for version 1.04_11 - 2008-03-09

  • use run_cc_test

Changes for version 1.04_10 - 2008-02-26

  • change bc pvx access dummy struct bytestate_xpv, so pv has the same fields as with 5.8, seperated from the sv. The sv is seperated from the pv. TODO: different strategy for B::C, must link xpv to sv
  • add and parse Assembler comments
  • add Bytecode comments to -S output unless -q
  • change op_reflags from U16 to U32
  • guarantee ByteLoader backwards compatibility: Accept lower versions also.

Changes for version 1.04_09 - 2008-02-25

  • improved make clean
  • add ByteLoader -Dt and -Dv debugging
  • don't link against jit code against possible sideeffects

  • fixed B::C xpvnv_list for 5.10
  • fixed B::C xpvio_list for 5.10
  • fixed B::C pmopsect for 5.11
  • bootstrap also all $Config{static_ext}, not only dynamic stashes

Changes for version 1.04_07 - 2008-02-20

  • moved bstate->bs_pv.xpv_pv slot to bs_pv.xiv_u.xivu_p1
  • fixed pv_free

Changes for version 1.04_02 - 2008-01-22

  • removed from CORE, now on CPAN.
  • 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

  • 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

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

    • 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

    • Change %lx to %x in B::CV::save to prevent some CV
