| | | | | | | | 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

| | | | | | 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 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

* 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

* PVFMs don't need CvDEPTH, and PVCVs don't use SvIVX, so movingNicholas Clark2006-02-201-6/+16
| | | | | | | | | xcv_depth into the IV union saves 4(ish) bytes per CV and format. "ish" because it was a long, but has been changed to I32 (along with the corresponding field in struct block_sub) so as not to enlarge the IV union on platforms where sizeof(long) > sizeof(IV), or struct block_sub where sizeof(long) > sizeof(I32) p4raw-id: //depot/perl@27247

| | | | | | | | | Message-ID: <43F0F649.9040205@gmail.com> Tweaked somewhat to split the arena boolean from the arena_size, and with the PTE still doubling-up with one of the SV types in the array. p4raw-id: //depot/perl@27215
