NAME

BcVersions - ByteLoader bytecode versions

CONTENTS

DESCRIPTION

Reference of tables of Asmdata files per perl - ByteLoader version.

5.005 had no ByteLoader VERSION. 5.005008 had 118 bytecodes, but no ByteLoader module and no header.

5.6 removed and added some opcodes.

With 5.8 several bytecodes were changed in the middle, and the number changed from 120 (5.008000) to 150 (5.008009).

With 5.10 it is not in CORE anymore, bytecode numbering juggled in development releases, while stable releases follow the static bytecode policy. New bytecodes are only added to the end, discontinued ops are nop’ed.

Since the CPAN release 6 new ops were added: op_latefree, op_latefreed, op_attached, op_reflags, cop_seq_low, cop_seq_high.

HOW TO

Create new versions:



  perlall=${perlall:-"5.6.0 5.6.1 5.6.2 5.8.0 5.8.0-nt 5.8.1 5.8.1-nt 5.8.2 5.8.3 5.8.4 5.8.5 5.8.6 5.8.8 5.8.8-nt 5.8.9 5.8.9-nt 5.10.0 5.10.0-nt 5.10.1 5.10.1-nt 5.12.0 5.12.1 5.13.4"}
  for p in $perlall
  do
    #make -q clean
    perl$p Makefile.PL
    v=`perl$p -MConfig -eprintf "%1.6f", $]|sed -es,5.,5_,`
    echo "perl$p $v"
    make lib/B/Asmdata.pm && sed -e"s,package B::Asmdata,package B::Asm$v," \
        <lib/B/Asmdata.pm >ByteLoader/BcVersions/Asm$v.pm
  done



In BcVersions/Asm5_0*.pm are all original Asmdata files from all previous releases, regardless of ITHREADs.
