As far as I understand, the first operand of dbg_declare should be a pointer (inside a metadata wrapper). However, using a non-pointer is currently not rejected, and we have some tests that use non-pointer types. As far as I can tell, these tests either meant to use dbg_value or are just incorrect hand-crafted tests. Ran into this while trying to `fix` #134008.
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'.
