Hi, GVN seems to be running in an infinite loop on my example. I have attached the output of one iteration. I cant seem to reduce the testcase either. Any pointers to how to reduce the test case. THanks, Arushi GVN iteration: 8 GVN WIDENED LOAD: %0 = load i8* getelementptr inbounds (%struct.CHESS_POSITION* @search, i64 0, i32 23), align 2, !dbg !875 TO: %1 = load i16* bitcast (i8* getelementptr inbounds (%struct.CHESS_POSITION* @search, i64 0, i32 23) to i16*), align 2 GVN COERCED INST: %0 = load i8* getelementptr inbounds (%struct.CHESS_POSITION* @search, i64 0, i32 23), align 2, !dbg !875 %1...

...it has a -timeout flag), I'd try it. Even if this doesn't help, please do file a bug with whatever you have. This is likely to be a recent regression. -Chris > > THanks, > Arushi > > GVN iteration: 8 > GVN WIDENED LOAD: %0 = load i8* getelementptr inbounds (%struct.CHESS_POSITION* @search, i64 0, i32 23), align 2, !dbg !875 > TO: %1 = load i16* bitcast (i8* getelementptr inbounds (%struct.CHESS_POSITION* @search, i64 0, i32 23) to i16*), align 2 > GVN COERCED INST: > %0 = load i8* getelementptr inbounds (%struct.CHESS_POSITION* @search, i64 0, i32 23), align 2,...
