From 4f2b21efb398e93293e0fcd97b203563ff53e228 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Wed, 19 May 2021 15:29:15 +0100 Subject: [PATCH] target/m68k: call gen_raise_exception() directly if single-stepping in gen_jmp_tb() In order to consolidate the single-step exception handling into a single helper, change gen_jmp_tb() so that it calls gen_raise_exception() directly instead of gen_exception(). This ensures that all single-step exceptions are now handled directly by gen_raise_exception().
