Subject: Make "ptype INTERNAL_FUNCTION" in Ada print like other languages
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=751495be92b2b319fb66ce4e12b562a0e27c15fe;p=binutils-gdb.git

Make "ptype INTERNAL_FUNCTION" in Ada print like other languages

Currently, printing the type of an internal function in Ada shows
double <>s, like:

 (gdb) with language ada -- ptype $_isvoid
 type = <<internal function>>

while all other languages print it with a single <>, like:

 (gdb) with language c -- ptype $_isvoid
 type = <internal function>

I don't think there's a reason that Ada needs to be different.  We
currently print the double <>s because we take this path in
ada_print_type:

    switch (type->code ())
      {
      default:
	gdb_printf (stream, "<");
	c_print_type (type, "", stream, show, level, language_ada, flags);
	gdb_printf (stream, ">");
	break;

... and the type's name already has the <>s.

Fix this by simply adding an early check for
TYPE_CODE_INTERNAL_FUNCTION.
