# RUN: llc -mtriple=aarch64 -run-pass=machine-outliner -verify-machineinstrs -stats %s -o - 2>&1 | FileCheck %s
# REQUIRES: asserts

# Check that instruction mapping stats work.

# We ought to map all of the instructions (5 of them) as legal, and then
# terminate the string with a single illegal character. Debug instructions are
# always invisible, and don't contribute to the length of the string.

# CHECK: 1 machine-outliner - Unoutlinable instructions mapped + number of sentinel values
# CHECK: 1 machine-outliner - Invisible instructions skipped during mapping
# CHECK: 5 machine-outliner - Outlinable instructions mapped
# CHECK: 1 machine-outliner - Sentinel values inserted during mapping
# CHECK: 6 machine-outliner - Total number of instructions mapped and saved to mapping vector
