From 0b00b0c1e05b34904635cf1b5cfdd945d1a8475e Mon Sep 17 00:00:00 2001 From: Ilya Leoshkevich Date: Fri, 16 Apr 2021 17:49:39 +0200 Subject: accel/tcg: Assert that tb->size != 0 after translation If arch-specific code generates a translation block of size 0, tb_gen_code() may generate a spurious exception. Add an assertion in order to catch such situations early.
