on the template class 'vec'.
This patch rewrites the old VEC macro-based interface into a new one
based on the template class 'vec'. The user-visible changes are
described in http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec.
I have tested the patch pretty extensively:
- Regular bootstraps on x86_64, ppc, ia64, sparc and hppa.
- Bootstraps with --enable-checking=release
- Bootstraps with --enable-checking=gc,gcac
- Basic builds on all targets (using contrib/config-list.mk).
We no longer access the vectors via VEC_* macros. The pattern is
"VEC_operation (T, A, V, args)" becomes "V.operation (args)".
The only thing I could not do is create proper ctors and dtors for the
vec class. Since these vectors are stored in unions, we
have to keep them as PODs (C++03 does not allow non-PODs in unions).
This means that creation and destruction must be explicit. There is a
new method vec<type, allocation, layout>::create() and another vec<type,
allocation, layout>::destroy() to allocate the internal vector.
For vectors that must be pointers, there is a family of free functions
that implement the operations that need to tolerate NULL vectors.
These functions all start with the prefix 'vec_safe_'. See the wiki
page for details.
The gengtype change removes the special handling for VEC() that used
to exist in gengtype. Additionally, it allows gengtype to recognize
templates of more than one argument and introduces the concept of an
undefined type (useful for template arguments that may or may not be
types).
When a TYPE_UNDEFINED is reached, gengtype will ignore it if it
happens inside a type marked with GTY((user)). Otherwise, it will
emit an error.
Finally, gengtype rejects root types marked GTY((user)) that are not
first class pointers.
