; RUN: llc -verify-machineinstrs -mtriple=aarch64-none-linux-gnu -o - %s | FileCheck %s ; Most important point here is that the promotion of the i1 works ; correctly. Previously LLVM thought that i64 was the appropriate SetCC output, ; which meant it proceded in two steps and produced an i64 -> i64 any_ext which ; couldn't be selected and faulted. ; It was expecting the smallest legal promotion of i1 to be the preferred SetCC ; type, so we'll satisfy it (this actually arguably gives better code anyway, ; with flag-manipulation operations allowed to use W-registers). declare {i64, i1} @llvm.umul.with.overflow.i64(i64, i64) define i64 @test_select(i64 %lhs, i64 %rhs) { ; CHECK-LABEL: test_select: %res = call {i64, i1} @llvm.umul.with.overflow.i64(i64 %lhs, i64 %rhs) %flag = extractvalue {i64, i1} %res, 1 %retval = select i1 %flag, i64 %lhs, i64 %rhs ret i64 %retval ; CHECK: ret }
