Changes for version 1.28 - 2010-12-31

  • fixed XSLoader, pmflags, CV and most named methods for 5.14
  • Bytecode.pm (1.09): fixed cv_gv and push_begin del_backref problem (27, ...) > 5.13 special cased op_pmflags: U32 needed since 5.13 (PMf_BASE_SHIFT) Fixes op_pmflags since 5.12 ((3..4,27..29,31,33), esp. pp_subst start for Windows 5.12 cop_store_label workaround: Labels disabled for now. Failed to include CORE hv.c: too large. mingw 5.12 compiles now again and passes all but 21,33,42..44 Fixed entrytry with Bytecode >= 5.12: ck_eval upgrades the UNOP entertry to a LOGOP, but B gets us just a B::OP (BASEOP) add BEGIN { push|unshift @INC } parts of blocks (test 33)
  • Byteloader (0.07): Support new CvSTASH_set. Basic op_pmflags U16/U32 support. No version conversion yet. BSET_gv_fetchpvn_flags: new for empty constant prototypes (fails on 64bit only)
  • C.pm: add -fno-destruct (with -O3) with a minimal perl_destruct, (re-enables -fcog >= 5.10), add -fro-inc (with -O2) readonly INC and curpad strings, add -fconst-strings (with -O3) const readonly strings and const more other fixed strings, do not boot static core packages (utf8, re, ...), fixed -O2/-fav-init2: store at wrong avchunk index, initialise CopFILE and CopSTASHPV static with ITHREADS improved 5.13 method_named package detection (first and pmreplroot), in endav still failing (Test::Deep) fixed overwritten CvSTART for 5.13.x do not cog/const nullify vars in END blocks disallow CONST->op_first with CONST_BARE. fixes ExtUtils::Install better XSLoader::load detection: aliases and defined in END blocks save XSLoader::load GV (test 46 and modules), still failing though bootstrap also static core packages add ptr_undef instead of NULL initialization non-threaded fix many cast warnings fix AV fill +1 required to run C.xs runloop to find PMOPs for QRs Fixed entrytry >= 5.12 as in Bytecode: ck_eval upgrades the UNOP entertry to a LOGOP, but B gets us just a B::OP (BASEOP) Fixed XSLoader, loading dynamic modules works now (test 45), had to set the .pm path in the calling context.
  • CC.pm (1.08): many fixes use new B::C optimizations, new -DF fixed issue 31 also run C.xs runloop to find PMOPs for QRs, fixed issue 35 same variable name in different scope (Heinz Knutzen), fixed issue 36 panic: leaveloop, no cxstack (Heinz Knutzen) fixed issue 37 orassign (Heinz Knutzen) fixed issue 38 on and/or return value not just no/yes (Heinz Knutzen) fixed issue 39 Bizarre copy of ARRAY in leavesub (Heinz Knutzen) fixed issue 42 remove enter/leave from %no_stack (Heinz Knutzen) fixed issue 44 aelemfast missing for lexicals (Heinz Knutzen) fixed issue 47 anonsub in while (Heinz Knutzen) fixed issue 48 wrong truth value for array assignment in boolean context (Heinz Knutzen) fixed issue 49 Can't "last" outside a loop block (Heinz Knutzen) fixed issue 51 errors on nested if statement with test on multiple variables (Heinz Knutzen) fixed issue 52 errors on variable with numeric value used in second expression of 'and' (Heinz Knutzen) add labels for alternate ops (e.g. run-time jumps). Not sure yet if the full alternate subtrees are saved. fixes test 32 (push_label, pop_label), issue 46. resolve duplicate such labels. honor $ENV{'PERLMODS'} (by cPanel)
  • Disassembler.pm (1.07): read over #! + use Bytecode .plc header. support pmflags
  • Assembler.pm (1.09): support pmflags
  • perlcc (2.09): added cc time for --time. same INC as in caller - omit duplicates
  • cc_harness: improve -Bstatic
  • t/testc.sh: simplified. Fixed various wrong tests
  • t/testm.sh: fixed UAC issues on Win7
  • t/test.pl: new faster test functions for the new issues
  • t/issue27.t: added (Reported by alexchorny, Apr 25, 2010)
