* [perl #43425] local $[: fix scoping during parser error handling.Dave Mitchell2007-07-161-359/+355
| | | | | | | | | 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

* Fix the overriding of CORE::do, just like change 25599Rafael Garcia-Suarez2005-09-271-1/+1
| | | | | was fixing the overriding of CORE::require p4raw-id: //depot/perl@25616
* CORE::require was always parsed as require().Rafael Garcia-Suarez2005-09-261-52/+62
| | | | | | | | | | | That's because require() isn't overridable at tokenizer-level like other overridable built-ins, but is handled by the optree builder. So, find a way to pass the information that require() was written as CORE::require() to Perl_ck_require. This is done by adding a new token type REQUIRE and by adding OPf_SPECIAL to OP_REQUIRE when it's saw as CORE::require in the program text. This fixes bug [perl #37274] The "CORE" in CORE::require is ignored. p4raw-id: //depot/perl@25599
