Hi Jason,

KDevelop parses files based on their MIME type, not the KTextEditor file mode. 
Check the MIME type of your file, e.g. via command `mimetype /path/to/file.ll`

An `#include` or a C/C++ comment at the top of a file can turn its MIME type 
into e.g. text/x-csrc. You can either modify the file to change its MIME type or 
add MIME type rule(s) based on the file extension (.ll) and/or contents. If you 
come up with good and general rules, you can contribute them to the Shared MIME 
Info database [1].

If the LSP Client plugin rather than KDevelop itself analyzes your file, you can 
disable the plugin or tweak its settings.
