[PATCH] Fix GCC6 -Wmisleading-indentation issues.
https://sourceware.org/ml/gdb-patches/2016-01/msg00632.html
commit a579cd9aa8c57c8a54833f26452a1afef38e5d20
Author: Mark Wielaard <mjw@redhat.com>
Date: Mon Jan 25 20:29:54 2016 +0100
Fix GCC6 -Wmisleading-indentation issues.
GCC6 will warn about misleading indentation issues like:
gdb/ada-lang.c: In function ‘ada_evaluate_subexp’:
ada-lang.c:11423:9: error: statement is indented as if it were guarded by...
arg1 = unwrap_value (arg1);
^~~~
gdb/ada-lang.c:11421:7: note: ...this ‘else’ clause, but it is not
else
^~~~
In this case it would be a bug except for the fact the if clause already
returned early. So this misindented statement really only got executed
for the else case. But it could easily mislead a reader, so adding a
proper else block is the correct solution.
In case of c-typeprint.c (c_type_print_base) the if statement is indeed
misleadingly indented, but not a bug. Just indent correctly. The inflow.c
(terminal_ours_1) misindented block comes from the removal of an if clause
in commit d9d2d8b which looks correct. Just introduce an else to fixup the
indentation of the block. The linux-record.c misleadingly indented return
statements are just that. Misleading to the reader, but not actual bugs.
Just unindent them so they don't look like they fall under the wrong if
clause.
