This function shouldn't fail to compile. (It's UB, so it doesn't really ; matter what it compiles to, exactly, but we need to check at some point ; so we don't generate code that requires an emergency spill slot we never ; allocated. If the store gets eliminated, this testcase probably needs ; to be rewritten.) define void @aligned_out_of_range_access(i32 %n, i32 %n2, i32 %n3, i32 %n4, [30 x i32]* byval([30 x i32]) %p) { ; CHECK-LABEL: aligned_out_of_range_access: ; CHECK: @ %bb.0: @ %entry ; CHECK-NEXT: .save {r4, r5, r6, r7, lr} ; CHECK-NEXT: push {r4, r5, r6, r7, lr} ; CHECK-NEXT: .setfp r7, sp, #12 ; CHECK-NEXT: add r7, sp, #12 ; CHECK-NEXT: .pad #44 ; CHECK-NEXT: sub sp, #44 ; CHECK-NEXT: mov r4, sp ; CHECK-NEXT: lsrs r4, r4, #4 ; CHECK-NEXT: lsls r4, r4, #4 ; CHECK-NEXT: mov sp, r4 ; CHECK-NEXT: add r0, sp, #16 ; CHECK-NEXT: adds r1, r7, #7 ; CHECK-NEXT: adds r1, #1 ; CHECK-NEXT: str r1, [sp, #12] @ 4-byte Spill ; CHECK-NEXT: @APP ; CHECK-NEXT: @NO_APP ; CHECK-NEXT: str r0, [sp, #8] @ 4-byte Spill ; CHECK-NEXT: ldr r0, [sp, #12] @ 4-byte Reload ; CHECK-NEXT: str r5, [r0, #120] ; CHECK-NEXT: ldr r0, [sp, #8] @ 4-byte Reload ; CHECK-NEXT: @APP ; CHECK-NEXT: @NO_APP ; CHECK-NEXT: subs r4, r7, #7 ; CHECK-NEXT: subs r4, #5 ; CHECK-NEXT: mov sp, r4 ; CHECK-NEXT: pop {r4, r5, r6, r7, pc} entry: %y = alloca [4 x i32], align 16 %pp = getelementptr inbounds [30 x i32], [30 x i32]* %p, i32 0, i32 0 %asm1 = call { i32, i32, i32, i32, i32, i32, i32 } asm "", "={r0},={r1},={r2},={r3},={r4},={r5},={r6},0,1,2,3,4,5,6"([4 x i32]* %y, i32* %pp, i32 undef, i32 undef, i32 undef, i32 undef, i32 undef) #3 %asmresult = extractvalue { i32, i32, i32, i32, i32, i32, i32 } %asm1, 0 %asmresult2 = extractvalue { i32, i32, i32, i32, i32, i32, i32 } %asm1, 1 %asmresult3 = extractvalue { i32, i32, i32, i32, i32, i32, i32 } %asm1, 2 %asmresult4 = extractvalue { i32, i32, i32, i32, i32, i32, i32 } %asm1, 3 %asmresult5 = extractvalue { i32, i32, i32, i32, i32, i32, i32 } %asm1, 4 %asmresult6 = extractvalue { i32, i32, i32, i32, i32, i32, i32 } %asm1, 5 %asmresult7 = extractvalue { i32, i32, i32, i32, i32, i32, i32 } %asm1, 6 %arrayidx = getelementptr inbounds i32, i32* %pp, i32 30 store i32 %asmresult6, i32* %arrayidx, align 4 call void asm sideeffect "", "{r0},{r1},{r2},{r3},{r4},{r5},{r6}"(i32 %asmresult, i32 %asmresult2, i32 %asmresult3, i32 %asmresult4, i32 %asmresult5, i32 %asmresult6, i32 %asmresult7) ret void }
