[Qemu-devel] [PATCH 4/4] tcg-hppa: Don't try to calls to non-constant addresses.

[Richard Henderson]

PA-RISC uses procedure descriptors.  We'd need to emit a call to
the millicode routine $$dyncall.  However, this situation doesn't
actually arise, since we always have the descriptor available at
TCG code generation time.
