From 04d59df6f311bcc20d74ada64a5e15a4bbb40026 Mon Sep 17 00:00:00 2001 From: Walfred Tedeschi Date: Tue, 21 Jun 2016 15:15:04 +0200 Subject: [PATCH] Improve user experience in printing Fortran derived types. Output for Fortran derived classes is like: "( 9, 'abc')" with this changes the output is changed to: "( lucky_number = 9, letters = 'abc')" 2016-06-21 Walfred Tedeschi * f-valprint.c (f_val_print): Add field names for printing derived types fields. gdb/testsuite: * gdb.fortran/derived-type.exp (print q): Add fields to the output. * gdb.fortran/vla-type.exp (print twov): Fix vla tests with structs. * gdb.fortran/derived-type-function.exp: New file. * gdb.fortran/derived-type-function.f90: New file. --- gdb/ChangeLog | 5 ++ gdb/f-valprint.c | 34 +++++++++--- gdb/testsuite/ChangeLog | 9 ++++ .../gdb.fortran/derived-type-function.exp | 38 +++++++++++++ .../gdb.fortran/derived-type-function.f90 | 62 ++++++++++++++++++++++ gdb/testsuite/gdb.fortran/derived-type.exp | 6 +-- gdb/testsuite/gdb.fortran/vla-type.exp | 4 +- 7 files changed, 145 insertions(+), 13 deletions(-) create mode 100644 gdb/testsuite/gdb.fortran/derived-type-function.exp create mode 100644 gdb/testsuite/gdb.fortran/derived-type-function.f90 diff --git a/gdb/ChangeLog b/gdb/ChangeLog index b4331ea..68c754f 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2016-06-21 Walfred Tedeschi + + * f-valprint.c (f_val_print): Add field names for printing + derived types fields. + 2016-06-21 Andreas Arnez * s390-linux-tdep.c (s390_iterate_over_regset_sections): Fix typo diff --git a/gdb/f-valprint.c b/gdb/f-valprint.c index 1264737..08215e2 100644 --- a/gdb/f-valprint.c +++ b/gdb/f-valprint.c @@ -219,6 +219,7 @@ f_val_print (struct type *type, const gdb_byte *valaddr, int embedded_offset, struct gdbarch *gdbarch = get_type_arch (type); enum bfd_endian byte_order = gdbarch_byte_order (gdbarch); unsigned int i = 0; /* Number of characters printed. */ + int printed_field = 0; /* Number of fields printed. */ struct type *elttype; CORE_ADDR addr; int index; @@ -337,15 +338,32 @@ f_val_print (struct type *type, const gdb_byte *valaddr, int embedded_offset, struct value *field = value_field ((struct value *)original_value, index); - val_print (value_type (field), - value_contents_for_printing (field), - value_embedded_offset (field), - value_address (field), stream, recurse + 1, - field, options, current_language); + struct type *field_type = check_typedef (TYPE_FIELD_TYPE (type, index)); - if (index != TYPE_NFIELDS (type) - 1) - fputs_filtered (", ", stream); - } + + if (TYPE_CODE (field_type) != TYPE_CODE_FUNC) + { + const char *field_name; + + if (printed_field > 0) + fputs_filtered (", ", stream); + + field_name = TYPE_FIELD_NAME (type, index); + if (field_name != NULL) + { + fputs_filtered (field_name, stream); + fputs_filtered (" = ", stream); + } + + val_print (value_type (field), + value_contents_for_printing (field), + value_embedded_offset (field), + value_address (field), stream, recurse + 1, + field, options, current_language); + + ++printed_field; + } + } fprintf_filtered (stream, " )"); break; diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index ae0edb3..7939954 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,12 @@ +2016-06-21 Walfred Tedeschi + + * gdb.fortran/derived-type.exp (print q): Add fields to the output. + * gdb.fortran/vla-type.exp (print twov): Fix vla tests with + structs. + * gdb.fortran/derived-type-function.exp: New file. + * gdb.fortran/derived-type-function.f90: New file. + + 2016-06-21 Pedro Alves * gdb.base/new-ui.exp: New file. diff --git a/gdb/testsuite/gdb.fortran/derived-type-function.exp b/gdb/testsuite/gdb.fortran/derived-type-function.exp new file mode 100644 index 0000000..2a9353b --- /dev/null +++ b/gdb/testsuite/gdb.fortran/derived-type-function.exp @@ -0,0 +1,38 @@ +# Copyright 2016 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.
