Actually, looking at other platforms, it seems like it’s more common to only do this when EmitCallSiteInfo is true. A comment on the previous phabricator patch mentions this. 

If MIPS requires CallSiteInfo for debugging for some reason, this can be an OR expression. 

Can you update the patch to match the other platforms here?
