I have found that tree-flow.h implements iteration over htab_t, while there is no current facility to do that with hash_table. Unfortunately, the specific form does not match the standard C++ approach to iterators. We have several choices.
(1) Ignore the problem and leave all such tables as htab_t. (2) Write new hash_table iteration functions to match the form of the existing GCC macro/function approach. (3) Write new hash_table iteration functions to match the form used by the C++ standard. This approach would entail modifying the loops. Diego and I have a preference for (3). What do you prefer? -- Lawrence Crowl
