Subject: [PATCH] Fix test issue with gcc-11
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8

Test 3.t exercises io_submit() with invalid addresses,
|
||
and one test attempted to pass in "-1" as an invalid
|
||
pointer. But gcc-11 realizes you cannot take an offset
|
||
from an invalid pointer, making it impossible to
|
||
compile or run this test:
|
||
|
||
> sh# make CC=gcc-11 partcheck
|
||
> make[1]: Entering directory '/alt/public_software/libaio/src'
|
||
> make[1]: Nothing to be done for 'all'.
|
||
> make[1]: Leaving directory '/alt/public_software/libaio/src'
|
||

|

|
||
|
||
The fix is to remove this one test case, since the compiler now
|
||
ensures the running code will never see this case.
