Subject: [PATCH] tests/prctl-sve: fix prctl(PR_SVE_GET_VL) return expected
|
||
|
|
value printing
|
||
|
|
|
||
|
|
* tests/prctl-sve.c: Print the expected return value string based
|
||
|
|
on the value returned, similarly to the way it is done
|
||
|
|
in tests/prctl-sme.c:print_sme_vl_arg().
|
||
|
|
|
||
|
|
Fixes: v5.13~8 "tests: improve test coverage of prctl syscall decoder"
|
||
|
|
Closes: https://github.com/strace/strace/issues/251
