Fix -Waddress warnings in nptl/tst-mutex1.c.
|
|
|
c6d234 |
|
|
|
c6d234 |
This patch fixes -Waddress warnings in nptl/tst-mutex1.c from
|
|
|
c6d234 |
comparing the address of an object with NULL (ATTR may either be NULL,
|
|
|
c6d234 |
or the address of an object when included from other tests, and the
|
|
|
c6d234 |
warning arises in the latter case). A macro ATTR_NULL is defined
|
|
|
c6d234 |
alongside ATTR and used for the tests.
|
|
|
c6d234 |
|
|
|
c6d234 |
Tested for x86_64.
|
|
|
c6d234 |
|
|
|
c6d234 |
* nptl/tst-mutex1.c: Include <stdbool.h>.
|
|
|
c6d234 |
[!ATTR] (ATTR_NULL): New macro.
|
|
|
c6d234 |
(do_test): Test !ATTR_NULL instead of ATTR != NULL.
|
|
|
c6d234 |
* nptl/tst-mutexpi1.c (ATTR_NULL): New macro.
|
|
|
c6d234 |
* nptl/tst-mutexpp1.c (ATTR_NULL): New macro.
