Correct. I was doing (featurep 'symref) by mistake instead of (featurep
'semantic/symref).

Yes, I am only talking about the case when xref-find-references is used. It
doesn't use global or idutils for that. After calls to
xref-find-references, the value of semantic-symref-tool stays at 'detect.

Only after I do M-: semantic-symref-detect-symref-tool, the value of
semantic-symref-tool changes to 'global (because I have GPATH file
generated in rootdir).

So global is not used at all by xref-find-references.

It was my mistake earlier; semantic/symref IS required. But
semantic-symref-detect-symref-tool doesn't seem be called at all because
the semantic-symref-tool value stays at 'detect unless I call
semantic-symref-detect-symref-tool manually.

Can you confirm the above?
