=head1 NAME experimental.ops - Experimental Opcodes =cut =head1 DESCRIPTION This file contains experimental opcodes. These opcodes should be considered implicitly deprecated - that is, they may be removed in any release. If you rely on any of these opcodes, please open a Trac ticket at L<https://trac.parrot.org/>. When making changes to any ops file, run C<make bootstrap-ops> to regenerate all generated ops files. =cut =head2 More Experimental Ops =over 4 =item B<trap>() Break into debugger. Implementation notes: - x86/gcc ... works with gdb - ppc/gcc ... works with gdb, to proceed: gdb> p $pc = $pc + 4 - TODO For other architectures, this is a C<noop>. =cut =item B<set_label>(invar PMC, inconst LABEL) Sets the opcode_t* label value for the given PMC. This is basically only useful for PMCs such as Sub, Continuation, ExceptionHandler and derivatives =item B<get_label>(out INT, invar PMC) Gets the opcode_t* label value from the given PMC. This is basically only useful for PMCs such as Sub, Continuation, ExceptionHandler and derivatives =cut =item B<fetch>(out PMC, in PMC, in PMC, in PMC) Fetches a value from $2, keyed by $3 into $1. If the resulting PMC is PMCNULL, uses the type in $4 to create and return a new PMC. =item B<fetch>(out PMC, in PMC, in INT, in PMC) =item B<fetch>(out PMC, in PMC, in STR, in PMC) =cut =item B<vivify>(out PMC, in PMC, in PMC, in PMC) Fetches a value from $2, keyed by $3 into $1. If the resulting PMC is PMCNULL, uses the type in $4 to create and return a new PMC. =item B<vivify>(out PMC, in PMC, in INT, in PMC) =item B<vivify>(out PMC, in PMC, in STR, in PMC) =cut =item B<new>(out PMC, in STR, in INT) =item B<new>(out PMC, in PMC, in INT) =cut =item B<root_new>(out PMC, in PMC, in INT) =cut =back =head1 COPYRIGHT Copyright (C) 2001-2010, Parrot Foundation. =head1 LICENSE This program is free software.
