From 1688cb2916e7bc46c92dd6f5ac2ba0da6c832274 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Tue, 5 Feb 2019 04:59:11 -0700 Subject: [PATCH] Hoist assertion in target_stack::unpush I noticed that target_stack::unpush first uses the target "t", then later asserts that it is non-NULL: strata stratum = t->stratum (); [...] gdb_assert (t != NULL); This is backwards, though, as the assertion must come first. gdb/ChangeLog 2019-02-05 Tom Tromey * target.c (target_stack::unpush): Move assertion earlier. --- gdb/ChangeLog | 4 ++++ gdb/target.c | 4 ++-- 2 files changed, 6 insertions(+), 2 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index b06398a..0ce33f2 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,7 @@ +2019-02-05 Tom Tromey + + * target.c (target_stack::unpush): Move assertion earlier. + 2019-01-30 Tom Tromey PR python/23615: diff --git a/gdb/target.c b/gdb/target.c index c5502ce..c1ab07f 100644 --- a/gdb/target.c +++ b/gdb/target.c @@ -598,14 +598,14 @@ unpush_target (struct target_ops *t) bool target_stack::unpush (target_ops *t) { + gdb_assert (t != NULL); + strata stratum = t->stratum (); if (stratum == dummy_stratum) internal_error (__FILE__, __LINE__, _("Attempt to unpush the dummy target")); - gdb_assert (t != NULL); - /* Look for the specified target.
