* make recursive part of peephole optimiser hookableZefram2010-08-261-0/+2
| | | | | | | | New variable PL_rpeepp makes it possible for extensions to hook the per-op-chain part of the peephole optimiser (which recurses into side chains). The existing variable PL_peepp still allows hooking the per-sub part of the peephole optimiser, maintaining perfect backward compatibility.
* Check API compatibility when loading xs modulesFlorian Ragwitz2010-07-261-0/+2
| | | | | | | | | | | | | This adds PL_apiversion, allowing the API version of a running interpreter to be introspected. It is used in the new XS_APIVERSION_BOOTCHECK macro, which is added to the _boot function of every XS module, to compare it against the API version the module has been compiled against. If the versions do not match, an exception is thrown. This doesn't fully prevent binary incompatible extensions to be loaded. It merely compares PERL_API_* between compile- and runtime, and does not attempt to solve the problem of identifying binary incompatible perls with the same API version (i.e. the same perl version configured with and without DEBUGGING).
* Get rid of PERL_POLLUTEJan Dubois2010-07-211-33/+0
| | | | | | | | | | | PERL_POLLUTE was added (but undefined by default) in 5.6 to optionally expose older 5.005 symbols for backwards compatibility. It's use was always discouraged, and MakeMaker contains a more specific escape hatch: perl Makefile.PL POLLUTE=1 This can be used for modules that have not been upgraded to 5.6 naming conventions (and really should be completely obsolete by now).
* Generic hooks into Perl_block_{start,end}.Ben Morrow2010-07-121-0/+2
| | | | | | | | | | These take the form of a vtable pushed onto the new PL_blockhooks array. This could probably do with a API around it later. Separate pre_end and post_end hooks are needed to capture globals before the stack is unwound (like needblockscope in the existing code). The intention is that once a vtable is installed it never gets removed, so where necessary extensions using this will need to use a hinthv element to determine whether to do anything or not.
* add PL_signalhook to hook into signal dispatchDavid Mitchell2010-06-041-0/+2
| | | | | This is initially intended for threads::shared and shouldn't (yet) be considered part of the public API.
* unwinding target nominated by separate globalZefram2010-04-251-0/+2
| | | | | | | | When unwinding due to die, the new global PL_restartjmpenv points to the JMP_ENV at which longjmping should stop and control should be transferred to PL_restartop. This replaces the previous use of cxstack[cxstack_ix+1].blk_eval.cur_top_env, located in a nominally-discarded context frame.

* Replace run-time on-demand initialisation of PL_bitcount with a constant table.Nicholas Clark2009-05-201-1/+0
| | | | | | | | | | | | | | | | (The table is 256 bytes; the run-time initialisation code is larger than this!) Adapt generate_uudmap.c to generate the initalisation block for PL_bitcount, writing the code to bitcount.h, using the same approach as uudmap.h. To preserve binary compatibility: for MULTIPLICITY: keep Ibitcount in the interpreter structure, but remove all the macros that access it. PL_bitcount is a new symbol in the object file, which won't clash with anything as that name wasn't used before. otherwise: keep PL_bitcount as a char *, but initialise it at compile time to a new constant array PL_bitcount array. Remove the code that attempts to Safefree() it at interpreter destruction time.

Additionally under MULTIPLICITY record the size of the interpreter structure (total, and for this version) and under PERL_GLOBAL_STRUCT the size of the global variables structure.
