Changes for version 1.08 - 2009-12-23

  • Adapt coding guidelines, add C and cperl coda. Reformat sources.
  • C.pm: Detect AUTOLOAD and CLONE (test 27 and 31). 5.10 is now the best release for unoptimized B::C. 5.8 is faster optimized, but misses some autoloaded xsubs. Simplify PVMG exclusion; all non-magical, not just PAD_OUR, as in Bytecode.
  • Bytecode.pm (1.04): Add missing BM logic to GV >= 5.10. Fixes test 11. Fixed op_pmflags logic for 5.10 threaded only, no += 2. Fixes test 2. Protect empty match from setting op_reflags. Fixes test 20. Now >=5.10 threaded has the same errors as non-threaded. Add perlversion to the -S generated header. Document more options -TI, -TF, -u<package>
  • perlcc: improve help. use Pod::Usage as module, not via cmdline. fix previous installation quirks.
  • assemble: improve pod. make it installable.
  • disassemble: make it installable.
  • cc_harness: ditto.
  • Makefile.PL: added script/* as EXE_FILES to install them.
  • t/TESTS, t/testc.sh, t/testplc.sh: test 31 non-xs AUTOLOAD added
  • ByteLoader/Makefile: tuning, bytecode.h triggers now byterun.c
  • bytecode.h: Specialize pregcomp on 5.10; add PL_regex_pad[0] for pregcomp if missing. fixes tests 3,4,5,7,31 on 5.10.
