Unit tests regressions!

[carlos4242]

I've just run the unit tests on avr-rust-2019-01-18 and I'm getting regressions?

Testing Time: 2.56s

---

Failing Tests (4):
LLVM :: CodeGen/AVR/call.ll
LLVM :: CodeGen/AVR/directmem.ll
LLVM :: CodeGen/AVR/div.ll
LLVM :: CodeGen/AVR/rem.ll

Expected Passes : 117
Expected Failures : 3
Unexpected Failures: 4

These are all fixed by avr-rust/llvm#10.

How do you run the unit tests (except running them for each file manually)?
llvm-lit does not work on my build. It does not have python variable llvm_config defined probably becase rust/src/llvm/test/lit.site.cfg.py.in is not processed to lit.site.cfg.py.

When you build llvm you’ll have a bin directory where llc, opt, etc. are located. In there is llvm-lit. Run it then pass the test directory. For example in my set up, I have the llvm source code in ~/llvm. The build is in a sub folder ~/llvm/build. To run lit I would do: ~/llvm/build/bin/llvm-lit ~/test/CodeGen/AVR Which runs all tests. Or append a single test.

Thanks. That is it. When you let rust build system to build llvm then it does not build llvm-lit and trying to run it from build/utils/llvm-lit does not work as I described before.

Since fixed in LLVM trunk.
