* function interface to parse Perl statementZefram2010-09-061-6/+26
| | | | | | | | | | | | | yyparse() becomes reentrant. The yacc stack and related resources are allocated in yyparse(), rather than in lex_start(), and they are localised to yyparse(), preserving their values from any outer parser. yyparse() now takes a parameter which determines which production it will parse at the top level. New API function parse_fullstmt() uses this facility to parse just a single statement. The top-level single-statement production that is used for this then messes with the parser's head so that the parsing stops without seeing EOF, and any lookahead token seen after the statement is pushed back to the lexer.

* [perl #43425] local $[: fix scoping during parser error handling.Dave Mitchell2007-07-161-0/+7
| | | | | | | | | Change 22306# inadvertently made 'local $[' statement-scoped rather than block-scoped; so revert that change and add a different fix. The problem was to ensure that the savestack got popped correctly while popping errored tokens. We how record the current value of PL_savestack_ix with each pushed parser state. p4raw-id: //depot/perl@31615

| | | | | | | | | | | | Repeat of change #28319 (backed out by change #28720), this time freeing ops using the right pad. Also backs out the remempad parser addition from change #29501; instead a new auxiliary paser stack is added, which records the current value of PL_comppad for every state. p4raw-link: @29501 on //depot/perl: 2af555bf3f2b3ca8e114df3f5f680d40bd24d6bf p4raw-link: @28720 on //depot/perl: c86b7e916b443ee192c5638ad9d077ad4e244713 p4raw-link: @28319 on //depot/perl: eb7d7d25d2f780edcbedc124a5bdca0d53ad8687 p4raw-id: //depot/perl@29504
