Changes for version 1.55 - 2017-02-10

  • C: Support 5.24 and 5.24c (ByteLoader and CC got broken with 5.22) Handle cperl OP_SIGNATURE, but not 5.26 signatures with its 3 new ops. Fix refcount of cop hints hashes with 5.22-nt (#220) Add missing B::FAKEOP::rettype for cperl-5.24, causing SEGV on B::CC Fixed shared xpviv with 5.24 on 32bit. Fix bytecode.pl call in cperl core. Optimize CopFILE_set by caching gv_fetchfile (CPANEL-7887) Abstract utf8_heavy loader (CPANEL-5417, CPANEL-6105, #369, #364) fixing redefinition warnings, fixing %INC (atoomic) Improve NV precision, use %17g (atoomic #373) Fix delayed cvref initialization of XS module functions (#376) Reset mg_flags without MGf_REFCOUNTED from the source (#390) Support uselongdouble LDBL_MIN/LDBL_MAX constants Fixed some IsCOW savepvn lengths (#396) Optimize mro_isa_changed_in initialization via a new B::HV::Gv_AMG idea by bdraco
  • ByteLoader: Fix various compiler warnings. Still broken upstream since 5.22
  • CC: PERL_OP_PARENT and 5.6 and 5.22 fixes. support utf8 labels. 5.24 mostly broken still, cperl 5.24c doing fine though.
  • META: fixed the bugtracker and repository

Changes for version 1.54_03 - 2016-05-09

  • Released with cperl-5.22.2
  • C: Remove hash argument from share_hek, always rehash. Work on PERL_DESTRUCT_LEVEL=2 Unbalanced string table refcount issues. Fix for CVf_CONST CVs with cperl (constant::import) Replace %Lu with %lu/%u Fix for shared xpviv with 5.24. This asserts now if unshared.
  • perlcc/cc_harness/TestBC: many more PERL_CORE fixes, to workaround broken ExtUtils::Embed::ldopts
  • tests: skip perlcc with -m32 cross and PERL_CORE. Can only work reliable on individual CPAN setups, but not with CORE smoking. Blame Configure Replace test.pl with TestBC.pm. Blame core harness
