From f74bd157c62f5c064418d038f9003c9c4b3dad0e Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 17 Sep 2021 19:10:25 -0700 Subject: target/i386: Implement x86_cpu_record_sigsegv MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Record cr2, error_code, and exception_index. That last means that we must exit to cpu_loop ourselves, instead of letting exception_index being overwritten. Use the maperr parameter to properly set PG_ERROR_P_MASK.
