Hi, The following test-cases broke due to the warning. I think however the warning is right for all the cases:
a) g++.dg/tree-ssa/invalid-dom.C: I believe the call from main() to E::bar() is dead call ? b) libffi/testsuite/libffi.call/float.c: Call from main() to floating() is dead call. c) libffi/testsuite/libffi.call/float3.c: Calls from main() to floating_1() and floating_2() are dead calls. d) libffi/testsuite/libffi.call/negint.c: Call from main() to checking () is dead call. Should I update the test-cases to pass -Wno-unsued-value, or remove the calls ? Thanks, Prathamesh
