gdb: add HtabPrinter to gdb-gdb.py.in
When debugging GDB, I find it a bit tedious to inspect htab_t objects.
It is possible to find the entries by poking at the fields, but it's
annoying to do each time. I think a pretty printer would help. Add a
basic one to gdb-gdb.py.
The pretty printer advertises itself as "array-like", and the result
looks like:
(top-gdb) p bfcache
$3 = htab_t with 3 elements = {0x6210003252a0, 0x62100032caa0, 0x62100033baa0}
The htab_t itself doesn't know about the type of pointed objects. But
it's easy enough to cast the addresses to the right type to use them:
(top-gdb) print *((btrace_frame_cache *) 0x6210003252a0)
$6 = {tp = 0x61700002ed80, frame = 0x6210003251e0, bfun = 0x62000000b390}
