I have created the testcase by modifying the one for PR 43835
(testsuite/gcc.c-torture/execute/pr43835.c), the shift could probably
be removed from the test altogether (but of course shift by 14 is also
fine with me, though I cannot approve anything). I'm just wondering
what kind of failure this causes (a compile time one?) and why that
same failure does not take place with the aforementioned pr43835.c
testcase...
BTW, unfortunately I have recently also added a bunch of such shifts
in testsuite/gcc.c-torture/execute/pr49886.c, are they OK?
Thanks,
Martin
