llvm dev - Mar 2018 - llvm-lit and FileCheck: How to ignore unsupported architecture for a specific test

Hi,

I was wondering if there is a way with llvm-lit and FileCheck to identify if a
specific test should run or not based on the processor architecture.

For example, I have a test that can run only in an Intel KNL, so if I run the
tests in a Sandybridge I want to ignore that test.

Any idea?

Thanks!
Simone

You can add a 'REQUIRES' line to a specific test (see
test/Assembler/return-column.s) for an example.

You may have to edit the lit configuration scripts to introduce a suitable
'available feature' when Intel KNL is available.
