From 120db3dfeb88c447f0e115c19b7ede704f8f80cb Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sat, 14 Jan 2023 13:05:41 -1000 Subject: [PATCH 2/8] tests/tcg/i386: Introduce and use reg_t consistently MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RH-Author: Paolo Bonzini RH-MergeRequest: 154: target/i386: fix bugs in emulation of BMI instructions RH-Bugzilla: 2173590 RH-Acked-by: Emanuele Giuseppe Esposito RH-Acked-by: Vitaly Kuznetsov RH-Acked-by: Bandan Das RH-Commit: [2/7] 843a677555414170392db21c828bef3dc3c29300 (bonzini/rhel-qemu-kvm) Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2173590 Upstream-Status: merged Define reg_t based on the actual register width. Define the inlines using that type. This will allow input registers to 32-bit insns to be set to 64-bit values on x86-64, which allows testing various edge cases.
