From fc59d2d870caddf5cd9c85836ee4a8c59ffe7617 Mon Sep 17 00:00:00 2001 From: Robert Foley Date: Mon, 18 Nov 2019 16:15:26 -0500 Subject: qemu_log_lock/unlock now preserves the qemu_logfile handle. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit qemu_log_lock() now returns a handle and qemu_log_unlock() receives a handle to unlock. This allows for changing the handle during logging and ensures the lock() and unlock() are for the same file. Also in target/tilegx/translate.c removed the qemu_log_lock()/unlock() calls (and the log("\n")), since the translator can longjmp out of the loop if it attempts to translate an instruction in an inaccessible page.
