From fee068e4f190a36ef3bda9aa7c802f90434ef8e5 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Wed, 29 Apr 2015 00:52:21 -0700 Subject: tcg: Delete unused cpu_pc_from_tb() No code uses the cpu_pc_from_tb() function. Delete from tricore and arm which each provide an unused implementation. Update the comment in tcg.h to reflect that this is obsoleted by synchronize_from_tb.
