* Remove all #ifdef MACOS_TRADITIONAL code in core and non-dual-life XS code.Nicholas Clark2009-04-271-5/+1
| | | | | | | | (MacOS support was removed from MakeMaker in 6.22, and merged to blead on 15th December 2004 with 5dca256ec738057dc331fb644a93eca44ad5fa14. After this point MacOS wouldn't even have been able to build the perl binary, because it would not have been able to build DynaLoader. If anyone wishes to resurrect MacOS, start by reversing this commit and the relevant part of that commit.)
* Fix MULTICALL in List-UtilAlex Vandiver2009-03-071-0/+3
| | | | | | | | Add a new stack frame; the MULTICALL code in pp_return assumes there is a clean stack, and blindly changes the top-most stack value. This change brings cop.h more in line with the "poor-man's MULTICALL" provided in ext/List-Util/multicall.h, which also always pushes a new stack.

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

* The layout for struct block_loop under ithreads can be simplified.Nicholas Clark2008-01-261-17/+18
| | | | | | | | | | | | | Instead of wedging the pad offset into a void* iterdata, and always storing PL_comppad even when it isn't used, instead do this: PAD *oldcomppad; /* Also used for the GV, if targoffset is 0 */ /* This is also accesible via cx->blk_loop.my_op->op_targ */ PADOFFSET targoffset; and store the GV pointer in oldcompad. Pointers to pointers seems cleaner. This also allows us to eliminate the flag bit CXp_PADVAR. p4raw-id: //depot/perl@33081
* Investigation reveals that the work of restoring the iterator to theNicholas Clark2008-01-261-16/+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
* As itersave points to the initial CxITERVAR(), and the state ofNicholas Clark2008-01-261-10/+7
| | | | | | | | | SvPADMY() does not change over the duration of the scope, we can perform conditional actions at loop push time. For the non-pad case, a reference to the initial CxITERVAR() is already held on the scope stack thanks to SAVEGENERICSV(*svp); in pp_enteriter. So there is no need to save another reference to it in itersave - it's not going away. p4raw-id: //depot/perl@33076

* In struct block_loop, merge itermax and iterlval into a unionNicholas Clark2008-01-241-18/+10
| | | | | | | | | lval_max_u, as CXt_LOOP_LAZYIV doesn't use iterlval and the other LOOP types don't use itermax. This reduces struct block_loop by 1 IV. As it's the largest component of the unions making up struct context, this reduces struct context. On ILP32 it will now be 56 bytes, down from the 64 of 5.10.x, as I've already removed the element 'label'. p4raw-id: //depot/perl@33063
