[Lldb-commits] [PATCH] D37533: Fix lldb-mi test data_read_memory_bytes_global

[Ted Woodward via Phabricator via lldb-commits]

ted created this revision.
Herald added a subscriber: aprantl.

Test was skipped because -data-evaluate-expression was thought
to not work on globals. This is not the case - the issue was clang
removes debug info for globals in cpp files that are not used.

Add a reference to the globals in question, and fix memory patter in
test to match memory pattern in testcase.
