Please include a line from a trace-events file that triggers the issue.
It's unclear to me what the problem is although I guess it's related to
TCGv_* types being rejected by validate_type. The
bit.startswith("TCGv_") change you mentioned sounds fine or a slightly
more general ALLOWED_TYPE_PREFIXES = ['TCGv_'].

This makes it clearer that "TCG_2_HOST" is a code reference:
# Magic substitution is done using tracetool.transform.TCG_2_HOST
