Subject: [PATCH for-7.2 0/2] target/i386: misc tcg patches
Date: Fri, 11 Nov 2022 21:40:42 +1000 [thread overview]
Message-ID: <20221111114044.2510256-1-richard.henderson@linaro.org> (raw)
While poking at cmpxchg{8,16}b this week, I remembered there
was a fix for cmpxchgl floating around. I pulled these two
fixes out of Paolo's i386 branch and added a test case.

Paolo Bonzini (2):
target/i386: fix cmpxchg with 32-bit register destination
target/i386: hardcode R_EAX as destination register for LAHF/SAHF
