However, it seems the warning at 404 is not generated on hppa64 and s390, but it is on other targets.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83453 --- Comment #4 from Martin Sebor --- The checking was relaxed to allow the attribute to specify a less restrictive alignment than the minimum provided by the target without triggering the warning, so the xfails can be removed. The rationale for the relaxation is that a looser alignment is trivially satisfied by providing a stricter alignment.

--- Comment #3 from John David Anglin ---
The test was fixed to handle error at 404 on hppa64 and s390:
inline int ATTR ((aligned (4)))
finline_hot_noret_align (int); /* { dg-warning "ignoring attribute .aligned
\
\(4\\). because it conflicts with attribute .aligned \\(8\\)." "" { target { !
{
hppa*64*-*-* s390*-*-* } } } } */
/* { dg-error "alignment for '.*finline_hot_noret_align.*' must be at least 8"
"
" { target hppa*64*-*-* s390*-*-* } .-1 } */
However, the error no longer occurs with gcc-9:
