gdb.mi/mi-pending.c: Return NULL instead of nothing in thread function
Using gcc 5.2 (maybe other versions as well), building mi-pending.c gives
these warnings:
./gdb.mi/mi-pending.c: In function â??thread_funcâ??:
./gdb.mi/mi-pending.c:34:5: warning: â??returnâ?? with no value, in function returning non-void
return;
^
./gdb.mi/mi-pending.c:38:5: warning: â??returnâ?? 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.
