Version 0.5 (protocol not changed; ABI changed)
- Allow to off turn the cycle detection code in data exchange at
compilation time. It should be at run time, but I'm short of time (and
the config stuff is still broken). That way, we keep dict of of the
critical path, which is good because the performance is poor:
- search not dichotomial yet
- dynar give no way to access their content and memcpy everytime
- In composed data description (struct, ref and so on), stop foolness of
keeping the subtype's ID, but store the type itself. This keeps sets out
of the critical path, which is good since they rely on dynar and
dictionnaries. The only loose of that is that we cannot detect the
redeclaration of a structure/union with another content (but I'm not sure
the code detected this error well before anyway). We still can detect
the redefinition discrepancy for the other types.
- Use a whole bunch of optimisation flags (plus -fno-strict-aliasing since
it breaks the code because of type-punning used all over the place).
This breaks on all non-gcc architectures (for now).
All those changes (plus the buffer of last time) allow me to gain 2 order
of magnitude on cruel tests consisting of 800000 array of integers on two
level of a hierarchical structure (200 secondes -> 4 secondes)
API change:
- the selector of reference must now return the type it points to, not
the ID of this type.
