Hi,
we emit spurious -Wparentheses warnings for template arguments,
evidently because we are not propagating TREE_NO_WARNING during
tsubstitution.
I'm fixing the problem in a straightforward way, by using the same idiom
already used elsewhere: call build_x_binary_op and then propagate
TREE_NO_WARNING to the resulting tree before returning it. The testcase
is somewhat extended vs that in the PR: I wanted to exercise the warning
a bit more and double check that we are still producing it when in order.
Tested x86_64-linux.
Thanks,
Paolo.
