Re-land D145441 with data layout upgrade code fixed to not break OpenMP. This reverts commit 3f2fbe92d0f40bcb46db7636db9ec3f7e7899b27. Differential Revision: https://reviews.llvm.org/D149776
This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
