call Instruction ¶This instruction has the syntax
call NONT, ORD
The instruction calls an assembler routine for parsing a nonterminal symbol NONT.
Execution continues just after the instruction on finishing parsing the nonterminal symbol.
The parameter ORD is the ordinal number of an AST node for the nonterminal symbol in an AST for a regular expression.
The parser uses that ordinal number to mark a part of the regular expression containing a parse error in a stack trace dumped on executing an abrt instruction.
Example:
call A, 2
This instruction calls an assembler routine for parsing the nonterminal symbol A.
The AST node of an occurrence of that nonterminal symbol in a regular expression has ordinal number 2.
