  • assemble, disassemble: added pod
  • B::Disassembler: Provide default printers print_insn (commented) and print_insn_bare. Portability: Use the header settings from the .plc and not the current perl settings.
  • 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.
  • Makefile.PL: Fixed script/perlcc.PL dependency make: *** No rule to make target `script/perlcc', needed by `blib/bin/perlcc'. (Thanks to david@cantrell.org.uk for his cpantest for solaris)

  • 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.

  • 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> 1998-04-14 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

  • 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)
  • 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.

  • 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
