Changes for version 1.47 - 2014-06-11

  • Fixed Bytecode for 5.18. Greatly reduce code size for C and esp. CC, by including less unneeded dependencies.
  • C: detect new Encode >2.58 compile-time usage (#305, RT #94221) Fix mro maybe::next:: detection (#326) Fix %INC cleanup logic. Delete packages from %INC only if they were really not saved, and add packages to %INC which were saved and not just marked for saving. (#340) Fix lot of skip package logic and consistency parts. Much less packages are now saved in general which leads to smaller and faster code. Avoid compile-time compiler internal reloads and redefinitions. Special-case %warning::Bits on -O3 to not SEGV when changing warnings on run-time loads on compile-time saved -fconst-string warnings. Add experimental -fwalkall to add all wanted packages recursively with maxdepth 3. No tests yet. Add time and version on top of C source code. Also for CC. Fix lexical subs for threaded perls (#130, #341) Add special fixes for Coro: reload Coro jit and SvREADONLY_off some of its XS symbols (#293) Fix "Eval-group not allowed at runtime" errors since 5.18 (#135), by settting HINT_RE_EVAL for re-eval groups when compiling the QR Fix for readonly magic hashes, usually found since 5.20 (#273) Fix Can't locate object method "bootstrap_inherit" via package "DynaLoader" (#125) again, as the improved walker now strips DynaLoader from simple one-liners like 'use Clone' and the DynaLoader detection was too late. Do it now earlier.
  • ByteLoader (0.11): fixed filter -H problem with 5.18 (#339) Disabling the PerlIO_binmode(PL_RSFP, IoTYPE_RDONLY, O_BINARY, 0); hack for [perl #86186] "Changing filters to be textmode, not binary" fixed the Bytecode problems since 5.18
  • perlcc (2.18): Avoid -H for bytecode > 5.18 New --check option
  • t/asmdata.t: signicant enhancements
  • t/CORE: add mro and re core tests, only mro/isarev.t is unstable, and several re-eval tests using variables are skipped and unsupported.
