* remove index offsetting ($[)Zefram2011-09-091-3/+0
| | | | | | $[ remains as a variable. It no longer has compile-time magic. At runtime, it always reads as zero, accepts a write of zero, but dies on writing any other value.

* add SAVEFREECOPHH()Zefram2010-10-281-0/+2
| | | | | Add the facility for the save stack to free (decrement the refcount of) a COPHH*.
* bad things happened with for $x (...) { *x = *y }David Mitchell2010-09-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | fix for [perl #21469]: since the GP may be pulled from under us and freed, coredumps and strange things can happen. Fix this by storing a pointer to the GV in the loop block, rather than a pointer to the GvSV slot. The ITHREADS variant already stores GV rather than than &GvSV; extend this to non-threaded builds too. Also, for both threaded and non-threaded, it used to push &GvSV on the save stack. Fix this by introducing a new save type, SAVEt_GVSV. This behaves similarly to SAVEt_SV, but without magic get/set. This means that for $package_var (...) is now close in behaviour to local $package_var = ... (except for the magic bit).
* When saving ints, if the value is small enough save it with the type.Nicholas Clark2010-05-051-0/+1
| | | | This uses a new type, SAVEt_INT_SMALL.
* When saving I32s, if the value is small enough save it with the type.Nicholas Clark2010-05-051-0/+1
| | | | This uses a new type, SAVEt_I32_SMALL.
* On the save stack, store the save type as the bottom 6 bits of a UV.Nicholas Clark2010-05-011-2/+7
| | | | This makes the other 26 (or 58) bits available for save data.
* remove bool* cast from SAVEBOOLDavid Mitchell2010-04-211-1/+1
| | | | | SAVEBOOL() should only be used on variables of type bool; casting pointers to variables of other types into bool* is just wrong.
* Skip the scope name checks if PL_scopestack_name is NULL.Nicholas Clark2009-11-181-4/+7
| | | | | | It's possible that someone has built a module with -DDEBUGGING, but they're using it against a perl built non-DEBUGGING, in which case PL_scopestack_name will be NULL. Better to skip the checks than to SEGV.
* Performance optimisation in assert, suggested by Tim BunceRafael Garcia-Suarez2009-11-151-1/+3
| | | | | | Most compilers will store only a single copy of identical literal strings. So changing that assert to check the pointer first would significantly reduce the cost.
* Add ENTER_with_name and LEAVE_with_name to automaticly check for matching ↵Gerard Goossen2009-11-121-0/+28
| | | | ENTER/LEAVE when debugging is enabled
* Introduce save_hdelete() and SAVEHDELETE()Vincent Pit2009-07-251-0/+2
| | | | save_hdelete() is just like save_delete() except that it takes an SV instead of char buffer.
* Add a new SAVEf_KEEPOLDELEM flag to save_scalar_at() and save_{a,h}elem_flags()Vincent Pit2009-07-251-0/+1
| | | | When set, save_scalar_at() doesn't replace the given SV by a fresh new one. local magic is not called in this case.
* Introduce save_aelem_flags()Vincent Pit2009-07-251-0/+1
| | | | It's the symmetric of save_helem_flags(). save_aelem() is now a macro wrapping around save_aelem_flags().
* The 2nd arg to save_alloc() must be cast to I32 to avoid pointer truncation ↵Jan Dubois2009-07-031-1/+1

| | | | | | | | | SSCHECK(2); SSPUSHPTR(o); SSPUSHINT(SAVEt_FREEOP); into a single function Perl_save_pushptr(ptr, type), which the others call. Implement the others as macros. This reduces the object code size. p4raw-id: //depot/perl@34956

* Add a macro MUTABLE_PTR(p), which on (non-pedantic) gcc will not castNicholas Clark2008-10-271-5/+5
| | | | | | | | | | away const, returning a void *. Add MUTABLE_SV(sv) which uses this, and replace all (SV *) casts either with MUTABLE_SV(sv), or (const SV *). This probably still needs some work - assigning to SvPVX() and SvRV() is now likely to generate a casting error. The core doesn't do this. But as-is it's finding bugs that can be fixed. p4raw-id: //depot/perl@34605

* Investigation reveals that the work of restoring the iterator to theNicholas Clark2008-01-261-2/+2
| | | | | | | | | | | | | | | | | pad is shared between POPLOOP, using itersave, and the end of scope restore action requested by Perl_save_padsv(). In fact, the only user of SAVEt_PADSV is pp_enteriter, and it already provides enough information to allow it to perform the sv_2mortal() in POPLOOP. So make it do so. Rather than creating a new routine, use the existing routine because nothing else (at least nothing else known to Google's codesearch) uses it. But rename it just in case something we can't see is being naughty and using our private functions - they will get link errors against 5.12. All this means that itersave is now redundant. So remove it. This makes struct context 48 bytes on ILP32 platforms with 32bit IVs, down from 64 bytes in 5.10. 33% more context stack in the same memory. p4raw-id: //depot/perl@33080
