From e99c1f89b2c9e779f17f3abab48ca78392977741 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 17 Apr 2023 17:40:35 +0100 Subject: linux-user: Add '-one-insn-per-tb' option equivalent to '-singlestep' MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The '-singlestep' option is confusing, because it doesn't actually have anything to do with single-stepping the CPU. What it does do is force TCG emulation to put one guest instruction in each TB, which can be useful in some situations. Create a new command line argument -one-insn-per-tb, so we can document that -singlestep is just a deprecated synonym for it, and eventually perhaps drop it.
