Andrew Stubbs <ams at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ams at gcc dot gnu.org --- Comment #9 from Andrew Stubbs <ams at gcc dot gnu.org> --- The testcase is undefined for targets that have no 128-bit type (i.e. long long is 64-bit, and __int128 doesn't exist). For (not yet in tree) GCN port I get "warning: right shift count >= width of type [-Wshift-count-overflow]", and then the execution test aborts.
