From 18920c42269018b87630cab5d90ed7b323dbfd55 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Fri, 1 Jul 2011 18:25:17 +0000 Subject: [PATCH] handle character-based enumeration typedefs Consider the following type: type Char_Enum_Type is ('A', 'B', 'C', 'D'); If the compiler generates a Char_Enum_Type typedef in the debugging information, the debugger fails in the following case: (gdb) p Char_Enum_Type'('B') $1 = 66 For our type, the underlying value of 'B' is actually 1, not 66 (ASCII 'B'). We are failing this case because we were not handling typedef to enum types before. This patch fixes this. gdb/ChangeLog: * ada-exp.y (convert_char_literal): Handle typedef types. gdb/testsuite/ChangeLog: * gdb.ada/char_enum: New testcase. --- gdb/ChangeLog | 4 ++++ gdb/ada-exp.y | 6 +++++- gdb/testsuite/ChangeLog | 4 ++++ gdb/testsuite/gdb.ada/char_enum.exp | 35 +++++++++++++++++++++++++++++++++ gdb/testsuite/gdb.ada/char_enum/foo.adb | 23 ++++++++++++++++++++++ gdb/testsuite/gdb.ada/char_enum/pck.adb | 22 +++++++++++++++++++++ gdb/testsuite/gdb.ada/char_enum/pck.ads | 21 ++++++++++++++++++++ 7 files changed, 114 insertions(+), 1 deletion(-) create mode 100644 gdb/testsuite/gdb.ada/char_enum.exp create mode 100644 gdb/testsuite/gdb.ada/char_enum/foo.adb create mode 100644 gdb/testsuite/gdb.ada/char_enum/pck.adb create mode 100644 gdb/testsuite/gdb.ada/char_enum/pck.ads diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 3c8f30d..87832cf 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,9 @@ 2011-07-01 Joel Brobecker + * ada-exp.y (convert_char_literal): Handle typedef types. + +2011-07-01 Joel Brobecker + * ada-lang.c (ada_remove_trailing_digits): Expand documentation. 2011-06-30 Tom Tromey diff --git a/gdb/ada-exp.y b/gdb/ada-exp.y index e64d1eb..9576be5e 100644 --- a/gdb/ada-exp.y +++ b/gdb/ada-exp.y @@ -1449,8 +1449,12 @@ convert_char_literal (struct type *type, LONGEST val) char name[7]; int f; - if (type == NULL || TYPE_CODE (type) != TYPE_CODE_ENUM) + if (type == NULL) return val; + type = check_typedef (type); + if (TYPE_CODE (type) != TYPE_CODE_ENUM) + return val; + xsnprintf (name, sizeof (name), "QU%02x", (int) val); for (f = 0; f < TYPE_NFIELDS (type); f += 1) { diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 1bf0ba0..79cbac0 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,7 @@ +2011-07-01 Joel Brobecker + + * gdb.ada/char_enum: New testcase. + 2011-07-02 Yao Qi * gdb.base/dump.exp (capture_pointer_with_type): New. diff --git a/gdb/testsuite/gdb.ada/char_enum.exp b/gdb/testsuite/gdb.ada/char_enum.exp new file mode 100644 index 0000000..b1996e3 --- /dev/null +++ b/gdb/testsuite/gdb.ada/char_enum.exp @@ -0,0 +1,35 @@ +# Copyright 2011 Free Software Foundation, Inc. +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
