* Add BmPREVIOUS_set(), and use it in the one place that BmPREVIOUS isNicholas Clark2006-12-111-0/+3
| | | | | modified. p4raw-id: //depot/perl@29525
* Move PERL_FBM_TABLE_OFFSET and PERL_FBM_FLAGS_OFFSET_FROM_TABLE to sv.hNicholas Clark2006-12-111-3/+15
| | | | | | Stow BmRARE in the SvPVX, and so delete xbm_rare. Can you see what it is yet? p4raw-id: //depot/perl@29524

* Change SvTAIL() to check that both SVpbm_TAIL|SVpbm_VALID are true.Nicholas Clark2006-12-111-6/+9
| | | | | | | SVpbm_VALID is the same bit value is SVf_IVisUV, which means that PVBMs can't actually ever be IOK. Therefore move BmUSEFUL() into the IV union, and save one I32 per PVBM. p4raw-id: //depot/perl@29518
* Swap SVpbm_TAIL and SVpbm_VALID.Nicholas Clark2006-12-101-2/+2

* Change 24714 was arguably over-ambitious, in that non-core modulesNicholas Clark2006-11-121-3/+19
| | | | | | | can't be expected to know that sv_setsv() may now not "really" copy a scalar. So arrange things so that COW of shared hash key scalars is only done for calls within the the PERL_CORE. p4raw-id: //depot/perl@29248

* Remove duplicate documentation for SvREFCNT_inc().Marcus Holland-Moritz2006-05-211-3/+6
| | | | | | Add documentation for SvREFCNT_inc_simple_void_NN(). Wrap SvREFCNT_inc_simple_void() in STMT_START/STMT_END. p4raw-id: //depot/perl@28266
* There is no STASH type.Marcus Holland-Moritz2006-05-191-1/+1
| | | p4raw-id: //depot/perl@28246
* Add a new macro SvVSTRING_mg that returns vstring magic, if any.Rafael Garcia-Suarez2006-05-171-0/+4
| | | | | | SvVOK used to do that, in stealth mode, but now it returns a boolean like it used to. Patch suggested by John Peacock. p4raw-id: //depot/perl@28218
* Introduce a new keyword, state, for state variables.Rafael Garcia-Suarez2006-05-031-1/+7

| | | | | inadvertently calling magic and overloading too often. p4raw-id: //depot/perl@28021
* Provide a new flag for sv_usepvn_flags, SV_HAS_TRAILING_NUL, whichNicholas Clark2006-04-161-0/+1
| | | | | | | signals that the buffer passed in is already well-formed for use as SvPVX (i.e. it is followed by a trailing NUL), and hence the realloc() to add a NUL can be skipped. p4raw-id: //depot/perl@27841
* Merge sv_usepvn and sv_usepvn_mg into sv_usepvn_flags. "Promote" theNicholas Clark2006-04-161-0/+2

* Expunge references to HV_AMAGIC, HV_AMAGICbad and HV_AMAGICmb whichNicholas Clark2006-03-151-5/+0

| | | | | (re)?blessing of overloaded objects to work correctly. p4raw-id: //depot/perl@27506
* SVphv_REHASH can use the same flag bit as SVf_FAKE. This allowsNicholas Clark2006-03-141-4/+3
| | | | | | 0x10000000 (SVf_AMAGIC) to be set on all 16 SV types, which seems to be necessary to fix subtle bugs involving reblessing and overloading. p4raw-id: //depot/perl@27496
* Move the GvNAME HEK into the IV union - every GV is now 1 pointerNicholas Clark2006-03-051-5/+12
| | | | | smaller. p4raw-id: //depot/perl@27380
* Use a HEK to store the GV's name, rather than a malloc()ed string.Nicholas Clark2006-03-051-4/+2
| | | | | | | Saves 1 word in each GV (no more strlen), and will also save the memory used by the string itself, as the HEK will exist already due to the key used by the symbol table for this GV. p4raw-id: //depot/perl@27379

* Store GvGP in the SV head union. For all the common lookups [eg GvCV()]Nicholas Clark2006-02-251-13/+29
| | | | | | | | this avoids 1 pointer dereference and the associated risk of a CPU cache miss. Although this patch looks deceptively small, I fear its CBV(*) might be rather high. (* Crack By Volume) p4raw-id: //depot/perl@27323
* Avoid special case SvMAGIC macros just to cope with Perl_sv_unmagic.Nicholas Clark2006-02-241-13/+4

* Use PVMGs rather than PVGVs to store the names of our variables in theNicholas Clark2006-02-241-1/+1

* Store the stash for our in the magic slot. This will allow us to useNicholas Clark2006-02-241-21/+41
| | | | | | PVMGs in pad names where previously PVGVs were used. In turn, this gives much greater flexibility for the layout of PVGVs. p4raw-id: //depot/perl@27312
* Replace usage of GvSTASH for storing the stash of C<our> withNicholas Clark2006-02-241-0/+7

* Redo previous sv.h change.Nicholas Clark2006-02-241-9/+10

* Replace direct flags tests & manipulations for SVpad_TYPED andNicholas Clark2006-02-231-0/+8
| | | | | | SVpad_OUR with macros SvPAD_TYPED(), SvPAD_OUR() etc, to abstract away the flags bits acutally used to store this information. p4raw-id: //depot/perl@27294
* Document a sixth use for SVf_FAKENicholas Clark2006-02-231-0/+3
| | | p4raw-id: //depot/perl@27293
* Remove get magic from typeglobs. This means that PVGVs holdingNicholas Clark2006-02-231-2/+2
| | | | | | | | | | | typeglobs never need to use SvPVX. This comes at price - typeglobs were using magic get for their stringificiation, and to pass SvOK(), so need to make typeglobs SvOK by default (by sucking SVp_SCREAM into SVf_OK - it's the only flag left), tweak SvSCREAM() to also check SVp_POK, and teach sv_2[inpu]v how to convert globs. However, it should free up SvPVX for the next part of the plan to pointer indirections, and therefore CPU cache pressure. p4raw-id: //depot/perl@27278
* Reorder the SV flags so that SVp_?OK and SVf_?OK occupy 8 contiguousNicholas Clark2006-02-211-24/+25
| | | | | | | bits (0x0000XX00). This makes perl 3K smaller with -Os on x86 FreeBSD, and might also help on other architectures (eg with 8 contiguous bits, the SvOK() test on ARM won't need an intermediate constant). p4raw-id: //depot/perl@27264
* Re-order the definitions of the private bits in SvFLAGS by value, soNicholas Clark2006-02-211-20/+30
