From 13e1dec8960122ec0329f74e5915503e14db5ea2 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Mon, 27 Jul 2015 15:49:24 -0400 Subject: [PATCH] gdb.mi/mi-pending.c: Return NULL instead of nothing in thread function MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Using gcc 5.2 (maybe other versions as well), building mi-pending.c gives these warnings: ./gdb.mi/mi-pending.c: In function ‘thread_func’: ./gdb.mi/mi-pending.c:34:5: warning: ‘return’ with no value, in function returning non-void return; ^ ./gdb.mi/mi-pending.c:38:5: warning: ‘return’ with no value, in function returning non-void return; ^ gdb_compile_pthreads assumes that the build was successful only if there is no output. These warnings therefore make gdb_compile_pthreads think that the build failed, and the test doesn't run. The easy fix is to replace the "return" with "return NULL". I am pushing this as obvious. gdb/testsuite/ChangeLog: * gdb.mi/mi-pending.c (thread_func): Replace return with return NULL. --- gdb/testsuite/ChangeLog | 4 ++++ gdb/testsuite/gdb.mi/mi-pending.c | 4 ++-- 2 files changed, 6 insertions(+), 2 deletions(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 73bc2b65b1..fd7c09c0ba 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,7 @@ +2015-07-27 Simon Marchi + + * gdb.mi/mi-pending.c (thread_func): Replace return with return NULL. + 2015-07-27 Simon Marchi * gdb.mi/mi-watch.exp (test_watchpoint_triggering): Remove xfail. diff --git a/gdb/testsuite/gdb.mi/mi-pending.c b/gdb/testsuite/gdb.mi/mi-pending.c index 248c7a8b0d..2f3464e2ee 100644 --- a/gdb/testsuite/gdb.mi/mi-pending.c +++ b/gdb/testsuite/gdb.mi/mi-pending.c @@ -31,11 +31,11 @@ thread_func (void* arg) h = dlopen (libname, RTLD_LAZY); /* set breakpoint here */ if (h == NULL) - return; + return NULL; p_func = dlsym (h, "pendfunc3"); if (p_func == NULL) - return; + return NULL; (*p_func) (); } -- 2.34.1
