[PATCH v5 4/4] accel/tcg: Move perf and debuginfo support to tcg
Posted by Philippe Mathieu-Daudé 2 years ago 
From: Ilya Leoshkevich <iii@linux.ibm.com>

tcg/ should not depend on accel/tcg/, but perf and debuginfo
support provided by the latter are being used by tcg/tcg.c.

Since that's the only user, move both to tcg/.
