From 988f6b3dc615173d6d78a76ac26c109b4582da74 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Fri, 25 Aug 2017 19:23:27 -0400 Subject: [PATCH] remove param "dispp" from ada-lang.c::ada_lookup_struct_elt_type The function is always called with DISPP set to NULL, so there is no need for this parameter anymore. This patch removes it, and eliminates some dead code associated to that. gdb/ChangeLog: * ada-lang.c (ada_lookup_struct_elt_type): Remove parameter "dispp". Update all callers accordingly. Remove all code blocks handling the case where DISPP is not NULL. Tested on x86_64-linux, no regression. --- gdb/ChangeLog | 6 ++++++ gdb/ada-lang.c | 43 ++++++++++++++----------------------------- 2 files changed, 20 insertions(+), 29 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index ff402163deb..39ff4edde14 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,9 @@ +2017-08-25 Joel Brobecker + + * ada-lang.c (ada_lookup_struct_elt_type): Remove parameter "dispp". + Update all callers accordingly.
