From: Alex Bennée Date: Thu, 29 Sep 2022 11:42:19 +0000 (+0100) Subject: contrib/plugins: reset skip when matching in execlog X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=8c1f1020d6e7dd329f5cf0cd8fd108dfb224eaec;p=people%2Fpauldu%2Fqemu.git contrib/plugins: reset skip when matching in execlog The purpose of the matches was to only track the execution of instructions we care about. Without resetting skip to the value at the start of the block we end up dumping all instructions after the match with the consequent load on the instrumentation.
