Subject: [Qemu-devel] [PATCH 1/2] target-mips: Add synci instruction test
Date: Tue, 29 Jul 2014 21:48:09 +0800 [thread overview]
Message-ID: <1406641690-6764-1-git-send-email-elta.era@gmail.com> (raw)
Save code with sw and raise synci. The saved code should be raise.
If the code raised, log 'test passed'.
If the code not raised, log 'test failed, the copied instruction not run'.
Other cases, log 'unhandled'.
The test should log 'test passed'.
