update_{llc,mir}_test_checks.py applicability is determined by the
output (assembly or MIR), not the input, which makes
update_llc_test_checks.py the right tool to generate tests that start at
MIR and stop at the final assembly.
This commit adds the minimal support for this path. Main limitation that
remains:
- MIR has to have LLVM IR section, and the CHECK lines will be inserted
into the LLVM IR functions that correspond to the MIR functions.
Running
../utils/update_llc_test_checks.py --llc-binary ./bin/llc
on a slightly modified ../test/CodeGen/X86/bad-tls-fold.mir
produces the following diff:
+# NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py

The LLVM Compiler Infrastructure
This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments.
