de125441 | 123 | B::Asmdata - Autogenerated data about Perl ops |
42d3a99d GS |
124 | |
125 | =head1 SYNOPSIS | |
126 | ||
4162ffa6 | 127 | use B::Asmdata qw(%insn_data @insn_name @optype @specialsv_name); |
42d3a99d GS |
128 | |
129 | =head1 DESCRIPTION | |
130 | ||
4162ffa6 MS |
131 | Provides information about Perl ops in order to generate bytecode via |
132 | a bunch of exported variables. Its mostly used by B::Assembler and | |
133 | B::Disassembler. | |
134 | ||
135 | =over 4 | |
136 | ||
137 | =item %insn_data | |
138 | ||
139 | my($bytecode_num, $put_sub, $get_meth) = @$insn_data{$op_name}; | |
140 | ||
141 | For a given $op_name (for example, 'cop_label', 'sv_flags', etc...) | |
142 | you get an array ref containing the bytecode number of the op, a | |
143 | reference to the subroutine used to 'PUT', and the name of the method | |
144 | used to 'GET'. | |
145 | ||
146 | =for _private | |
147 | Add more detail about what $put_sub and $get_meth are and how to use them. | |
148 | ||
149 | =item @insn_name | |
150 | ||
151 | my $op_name = $insn_name[$bytecode_num]; | |
152 | ||
153 | A simple mapping of the bytecode number to the name of the op. | |
154 | Suitable for using with %insn_data like so: | |
155 | ||
156 | my $op_info = $insn_data{$insn_name[$bytecode_num]}; | |
157 | ||
158 | =item @optype | |
159 | ||
160 | my $op_type = $optype[$op_type_num]; | |
161 | ||
162 | A simple mapping of the op type number to its type (like 'COP' or 'BINOP'). | |
163 | ||
164 | =item @specialsv_name | |
165 | ||
166 | my $sv_name = $specialsv_name[$sv_index]; | |
167 | ||
168 | Certain SV types are considered 'special'. They're represented by | |
3c4b39be | 169 | B::SPECIAL and are referred to by a number from the specialsv_list. |
4162ffa6 MS |
170 | This array maps that number back to the name of the SV (like 'Nullsv' |
171 | or '&PL_sv_undef'). | |
