From d19937a74c51872e8bbff6e37d9b89b202519b07 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Mon, 23 Nov 2020 21:48:23 -0500 Subject: Make fixed_point_type_base_type a method of struct type As suggested by Simon, to logically connect this function to the object it inspects. Note that, logically, this method should be "const". Unfortunately, the implementation iterates on struct type objects starting with "this", and thus trying to declare the method "const" triggers a compilation error. gdb/ChangeLog: * gdbtypes.h (struct type) New method, replacing the fixed_point_type_base_type function. All callers updated throughout this project. (fixed_point_type_base_type): Remove declaration. * gdbtypes.c (type::fixed_point_type_base_type): Replaces fixed_point_type_base_type. Adjust implementation accordingly. --- gdb/ChangeLog | 9 +++++++++ gdb/ada-valprint.c | 2 +- gdb/gdbtypes.c | 6 ++++-- gdb/gdbtypes.h | 17 +++++++++-------- gdb/valprint.c | 2 +- gdb/value.c | 2 +- 6 files changed, 25 insertions(+), 13 deletions(-) (limited to 'gdb') diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 5e34c7e..3db6365 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,14 @@ 2020-11-24 Joel Brobecker + * gdbtypes.h (struct type) New method, + replacing the fixed_point_type_base_type function.
