Check for #0 anyways, if the test fails with a false 10*9880d681SAndroid Build Coastguard Worker; positive, the second check can be eliminated, or rewritten, and in the 11*9880d681SAndroid Build Coastguard Worker; meantime it can help catch real problems. 12*9880d681SAndroid Build Coastguard Worker; CHECK: dcfetch({{.*}}+{{ *}}#0) 13*9880d681SAndroid Build Coastguard Workertarget datalayout = "e-p:32:32:32-i64:64:64-i32:32:32-i16:16:16-i1:32:32-f64:64:64-f32:32:32-v64:64:64-v32:32:32-a0:0-n16:32" 14*9880d681SAndroid Build Coastguard Workertarget triple = "hexagon" 15*9880d681SAndroid Build Coastguard Worker 16*9880d681SAndroid Build Coastguard Workerdefine void @foo(i8* %addr) nounwind { 17*9880d681SAndroid Build Coastguard Workerentry: 18*9880d681SAndroid Build Coastguard Worker %addr.addr = alloca i8*, align 4 19*9880d681SAndroid Build Coastguard Worker store i8* %addr, i8** %addr.addr, align 4 20*9880d681SAndroid Build Coastguard Worker %0 = load i8*, i8** %addr.addr, align 4 21*9880d681SAndroid Build Coastguard Worker %1 = getelementptr i8, i8* %0, i32 8 22*9880d681SAndroid Build Coastguard Worker call void @llvm.prefetch(i8* %1, i32 0, i32 3, i32 1) 23*9880d681SAndroid Build Coastguard Worker %2 = getelementptr i8, i8* %0, i32 9 24*9880d681SAndroid Build Coastguard Worker call void @llvm.prefetch(i8* %2, i32 0, i32 3, i32 1) 25*9880d681SAndroid Build Coastguard Worker ret void 26*9880d681SAndroid Build Coastguard Worker} 27*9880d681SAndroid Build Coastguard Worker 28*9880d681SAndroid Build Coastguard Workerdeclare void @llvm.prefetch(i8* nocapture, i32, i32, i32) nounwind 29
