## Checks two things:
# - matching functions in AMDGPU assembly output without certain comments in the assembly
# - using the --tool and --default-march arguments
# Using `cat` as a tool requires some unusual setup (compared to the other test
# of UpdateTestChecks tools), because update_llc_test_checks only reliably
# substitutes %S (source directory) when evaluating RUN lines in the .ll file.
# The .ll file used during the test is a temporary copy, so we also need to
# provide a temporary copy of the cat'd .s file to avoid relying on
# implementation details of how llvm-lit chooses %t.
# RUN: rm -rf %t.dir && mkdir %t.dir
# RUN: cp -f %S/Inputs/amdgpu_function_alt.s %t.dir/
# RUN: cp -f %S/Inputs/amdgpu_function_alt.ll %t.dir/
# RUN: %update_llc_test_checks --llc-binary "" --tool cat --default-march=amdgcn --version 4 %t.dir/amdgpu_function_alt.ll
# RUN: diff -u %S/Inputs/amdgpu_function_alt.ll.expected %t.dir/amdgpu_function_alt.ll
# Check that re-running remembers the arguments and doesn't change anything
# RUN: %update_llc_test_checks --llc-binary "" %t.dir/amdgpu_function_alt.ll
# RUN: diff -u %S/Inputs/amdgpu_function_alt.ll.expected %t.dir/amdgpu_function_alt.ll
