Summary: They're not always mutually exclusive. read-modify-write atomics are both at the same time. One example of this is the SWP instructions on AArch64. Another example is GlobalISel's G_ATOMICRMW_* generic instructions which will be added in a later patch.

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'.
