# RUN: llc -mtriple=aarch64-unknown-linux-gnu -o - %s -run-pass=aarch64-cond-br-tuning | FileCheck %s

# This testcase was obtained by looking at FileCheck.cpp and reducing it down via llvm-reduce

# Check that the ANDXri preserves the debug info by retaining the debug-instr-number 1 in _ZN4llvmlsERNS_11raw_ostreamERKNS_5ErrorE after the aarch64-cond-br-tuning pass transforms it into a ANDSXri instruction.

# CHECK: %{{[0-9]+}}:gpr64common = ANDSXri %{{[0-9]+}}, {{[0-9]+}}, implicit-def $nzcv, debug-instr-number 1
# CHECK-NEXT: DBG_INSTR_REF !{{[0-9]+}}, !DIExpression(DW_OP_LLVM_arg, 0), dbg-instr-ref(1, 0)
