"unsupported language" error in info types when using Ada.
This implements a rudimentary version of the la_print_typedef method
for Ada. Ada usually does not use typedefs, but there is one exception:
pointers to unconstrained arrays. Without this patch, we sometimes
get an error in the "info types" output:
(gdb) info types new_integer_type
All types matching regular expression "new_integer_type":
File foo.adb:
Language not supported.
For now, we treat the typedef as if it did not exist - using the
underlying type instead. This is the right thing to do for most cases,
the only exception being access to array types. Since we already have
a general issue in handling these pointers (we confuse them with fat
pointers), we will enhance ada_print_typedef to handle these pointers
at the same time we address the general issue.
gdb/ChangeLog:
* ada-typeprint.c (ada_print_typedef): New function.
* ada-lang.h (ada_print_typedef): Add declaration.
* ada-lang.c (ada_language_defn): set la_print_typdef field
to ada_print_typedef.
gdb/testsuite/ChangeLog:
* info_types.c, info_types.exp: New files.
Tested on x86_64-linux.
