=head1 NAME

BcVersions - ByteLoader bytecode versions

=head1 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.

=head1 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 -e'printf "%1.6f", $]'|sed -e's,5.,5_,'`
    echo "perl$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 F<BcVersions/Asm5_0*.pm> are all original Asmdata files from all previous releases,
regardless of ITHREADs.
