| 190 | =head1 NAME |
| 191 | |
| 192 | B::Asmdata - Autogenerated data about Perl ops, used to generate bytecode |
| 193 | |
| 194 | =head1 SYNOPSIS |
| 195 | |
| 196 | use B::Asmdata qw(%insn_data @insn_name @optype @specialsv_name); |
| 197 | |
| 198 | =head1 DESCRIPTION |
| 199 | |
| 200 | Provides information about Perl ops in order to generate bytecode via |
| 201 | a bunch of exported variables. Its mostly used by B::Assembler and |
| 202 | B::Disassembler. |
| 203 | |
| 204 | =over 4 |
| 205 | |
| 206 | =item %insn_data |
| 207 | |
| 208 | my($bytecode_num, $put_sub, $get_meth) = @$insn_data{$op_name}; |
| 209 | |
| 210 | For a given $op_name (for example, 'cop_label', 'sv_flags', etc...) |
| 211 | you get an array ref containing the bytecode number of the op, a |
| 212 | reference to the subroutine used to 'PUT', and the name of the method |
| 213 | used to 'GET'. |
| 214 | |
| 215 | =for _private |
| 216 | Add more detail about what $put_sub and $get_meth are and how to use them. |
| 217 | |
| 218 | =item @insn_name |
| 219 | |
| 220 | my $op_name = $insn_name[$bytecode_num]; |
| 221 | |
| 222 | A simple mapping of the bytecode number to the name of the op. |
| 223 | Suitable for using with %insn_data like so: |
| 224 | |
| 225 | my $op_info = $insn_data{$insn_name[$bytecode_num]}; |
| 226 | |
| 227 | =item @optype |
| 228 | |
| 229 | my $op_type = $optype[$op_type_num]; |
| 230 | |
| 231 | A simple mapping of the op type number to its type (like 'COP' or 'BINOP'). |
| 232 | |
| 233 | =item @specialsv_name |
| 234 | |
| 235 | my $sv_name = $specialsv_name[$sv_index]; |
| 236 | |
| 237 | Certain SV types are considered 'special'. They're represented by |
| 238 | B::SPECIAL and are referred to by a number from the specialsv_list. |
| 239 | This array maps that number back to the name of the SV (like 'Nullsv' |
| 240 | or '&PL_sv_undef'). |
