From 2f41223f62de5d893bd6a4bd832293c2c3e80d91 Mon Sep 17 00:00:00 2001 From: Antoine Tremblay Date: Wed, 25 Feb 2015 11:00:01 -0500 Subject: Fix print of value type in a corner case of finish When doing finish in a function, if gdb fails to return a value, gdb also fails at printing the value type if this type is a struct. For example : (gdb) fin .... Value returned has type: . Cannot determine contents This patch fixes this by calling type_to_string to print the type so that we can support these types. This patch returns the following example output : (gdb) fin .... Value returned has type: struct test. Cannot determine contents Also, this patch modifies structs.exp to check that we return the correct type. gdb/ChangeLog: * gdb/infcmd.c (print_return_value): use type_to_string to print type. gdb/testsuite/ChangeLog: * gdb.base/structs.exp: Check for correct struct on finish. --- gdb/infcmd.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'gdb/infcmd.c') diff --git a/gdb/infcmd.c b/gdb/infcmd.c index 9a1fb8d..3737b8f 100644 --- a/gdb/infcmd.c +++ b/gdb/infcmd.c @@ -1607,10 +1607,16 @@ print_return_value (struct value *function, struct type *value_type) } else { + struct cleanup *oldchain; + char *type_name; + + type_name = type_to_string (value_type); + oldchain = make_cleanup (xfree, type_name); ui_out_text (uiout, "Value returned has type: "); - ui_out_field_string (uiout, "return-type", TYPE_NAME (value_type)); + ui_out_field_string (uiout, "return-type", type_name); ui_out_text (uiout, "."); ui_out_text (uiout, " Cannot determine contents\n"); + do_cleanups (oldchain); } } -- cgit v1.1
