This patch by Cherry Zhang skips the testSetPanicOnFault tests when

This change is aimed at getting rid of spurious -Wuninitialized warnings
issued for small records passed by copy and containing default values
for some of their components.
The source of the problem is that the _Init parameter of the

compiler about size of types and objects, so that it cannot evaluate the

as it can neither veri

Hi!
As the following testcase additions show, even the TYPE_MAX_VALUE var needs
to be forced into temporary if it is a user variable, otherwise if that
variable is changed by the user before taskgroup ends, we don't handle it
correctly.

Hi.
In non-LTO mode, we should not set hotness according to computed histogram
in ipa-profile. Following patch does that and fixes the test-case isolated
from PR.
Patch survives regression tests on x86_64-linux-gnu.
Ready for trunk?

There's another move of C++ tests, this time these that have dg-require-ifunc.
