I have some issues with the vector-compare-2.c torture test. It passes a
vector by value (argument and return type), which is likely to warn (although
for some reason it doesn't for me, with today's compiler). And it takes
-Wno-psabi through a .x file, but those are not read in c-c++-common, so I
put it in dg-options. I would have changed the function to use pointers, but
I don't know if it specifically wants to test passing by value...
Hello,
Pat Haugen just explained it to me: there was a default -w option in the
old location of the testcase. However, there isn't in the new one. I am
thus proposing the following, which restores the old behavior. Note that
-Wno-psabi is still needed as it is not implied by -w.
