189 | =head1 NAME |
190 | |
191 | B::Asmdata - Autogenerated data about Perl ops, used to generate bytecode |
192 | |
193 | =head1 SYNOPSIS |
194 | |
4162ffa6 |
195 | use B::Asmdata qw(%insn_data @insn_name @optype @specialsv_name); |
42d3a99d |
196 | |
197 | =head1 DESCRIPTION |
198 | |
4162ffa6 |
199 | Provides information about Perl ops in order to generate bytecode via |
200 | a bunch of exported variables. Its mostly used by B::Assembler and |
201 | B::Disassembler. |
202 | |
203 | =over 4 |
204 | |
205 | =item %insn_data |
206 | |
207 | my($bytecode_num, $put_sub, $get_meth) = @$insn_data{$op_name}; |
208 | |
209 | For a given $op_name (for example, 'cop_label', 'sv_flags', etc...) |
210 | you get an array ref containing the bytecode number of the op, a |
211 | reference to the subroutine used to 'PUT', and the name of the method |
212 | used to 'GET'. |
213 | |
214 | =for _private |
215 | Add more detail about what $put_sub and $get_meth are and how to use them. |
216 | |
217 | =item @insn_name |
218 | |
219 | my $op_name = $insn_name[$bytecode_num]; |
220 | |
221 | A simple mapping of the bytecode number to the name of the op. |
222 | Suitable for using with %insn_data like so: |
223 | |
224 | my $op_info = $insn_data{$insn_name[$bytecode_num]}; |
225 | |
226 | =item @optype |
227 | |
228 | my $op_type = $optype[$op_type_num]; |
229 | |
230 | A simple mapping of the op type number to its type (like 'COP' or 'BINOP'). |
231 | |
232 | =item @specialsv_name |
233 | |
234 | my $sv_name = $specialsv_name[$sv_index]; |
235 | |
236 | Certain SV types are considered 'special'. They're represented by |
237 | B::SPECIAL and are refered to by a number from the specialsv_list. |
238 | This array maps that number back to the name of the SV (like 'Nullsv' |
239 | or '&PL_sv_undef'). |
