1 # This file shows the history of incompatible changes to
2 # Parrot that invalidated existing PBC (Parrot Byte Code) files.
4 # The latest version number of the bytecode format in this file
5 # is used by Parrot to version the bytecode files it writes and
6 # is able to read. In the future, Parrot should be able to read
7 # and/or write older bytecode versions too.
9 # Currently known actions that should be entered here
10 # (and invalidate PBC are):
12 # - deleting/changing/inserting existing ops in ops.num
13 # - changing operands of existing ops
14 # - adding/deleting/renaming a PMC to classes
15 # - changes in the packfile format itself
16 # - changes to any PMCs that are frozen into the .pbc like
17 # ParrotInterpreter (HLL_info), Subs and more
18 # - other core changes that invalidate byte code :)
20 # After changing PBC_COMPAT either disable t/native_pbc tests or
21 # better, if you have an i386 box at hand, regenerate the PBCs
22 # with tools/dev/mk_native_pbc and commit the changes
24 # or TODO much better: all .pbc files should make-depend on PBC_COMPAT
26 # Also, if you're removing an opcode, be sure to run
27 # make -f tools/dev/ops_renum.mak
29 # please insert tab separated entries at the top of the list
