Changes for version 1.48 - 2014-07-11

  • Fixed C walker and 5.18-5.20 Bytecode. This is the major version which cPanel will use for 5.14.4. With the next versions we'll start working on -m and buildcc, to split packages into shared libs. And use B::CC and/or rperl compiled modules selectively.
  • C: Make revised -fwalkall the default. Fixes missing dumped method-only packages (#348) Always save all user-loaded packages. Skip only compiler-loaded packages if not used by user code. The compiler loads and dumps now additionally only the heavy parts for utf8 and bytes, and utf8 for m///i, and AnyDBM for dbmopen, PerlIO::Scalar for __DATA__ handles, and Coro::State::_jit if required, but nothing else. Fix for missing RTLD_NOLOAD on BSD, needed for run-time remap of compile-time XS symbols via dlsym (#351) Special-case XS loading of Moose.xs from Class::MOP (#350) Better fix for mult. match once by checking OP_MATCH with ONCE flags in C.xs also (#274) but there are still some platforms without pmop->op_pmregexp in the C.xs detection runloop Add op_lastsib bit for 5.21.2 Changed IO::Socket::SSL warning as our patch was rejected upstream. Need to maintain now a fork cPanel::IO::Socket::SSL to be able to use compiled IO::Socket::SSL servers. (#317)
  • Stackobj (1.12): Harmonize RV checks (fixes cc 105 -O1 and -O2)
  • Bytecode (1.16): Replace each %hash with foreach keys in walksymtable also (#307) Do not store main_cv->START, empty optree since 5.18 Add op_lastsib for 5.21.2, but sort still broken with PERL_OP_PARENT
  • Assembler (1.12): error if a PUT method misses an argument
  • perlcc (2.19): -B produces again -H bytecode, runnable without -MByteLoader. Fix default output name from a.outexe to a.exe on a windows-based OS.
  • Makefile.PL: fix installation of cc_runtime.h for B::CC
