Maybe vararg it. appropriate changes to parseXS too. <br><br> SvPV, return a struct, len goes into EDX only on EAX EDX return platforms like win32 32 bit x86, saved 0x200 instruction bytes in interp in crude test <br><br> look through old tickets which weren't applied yet <br><br> fastcall on msvc gcc 32 bit, 10% faster in perlbench <br><br> regcall on intel c, sounds much better than fastcall, and structs returned in regs on x64 supposedly, see SvPV EAX EDX item <br><br> strlen audit <br><br> too many upg_version calls on PL_patchlevel, see http://www.nntp.perl.org/group/perl.perl5.porters/2012/11/msg196004.html <br><br> speed test siphash on 32 bit x86 with non native i64s vs one at a time [href://http://perl5.git.perl.org/perl.git/commit/3db6cbfca39da94d152d3e860e2aa79b9c6bb161], mostly done <br><br> win32 Perl_init_os_extras, remove the GetProcAddress overhead, now that PERL_IS_MINIPERL define exists from makefiles <br><br> av_fetch_flags, never returns null, will return PL_sv_undef instead. Removes a common idiom. Turning lval param into a flags will cost zero instructions, since there is always an lval param right now anyways. <br><br> remove context from Perl_mg_find* and S_mg_findext_flags, use .fnc for back compatb 2013-05-23 08:40:48 2654 857303 469 America/New_York
