Re: [Qemu-devel] arm-linux-user, i386-linux-user: Make QEMU act as TCG compiler
QEMU as a dynamic translator is already available. This adds extra functionality to QEMU. I needed to do this since I wanted to explore the ARM memory model over TCG micro-operations; so I needed translation of the whole binary and not just the parts which QEMU needs to execute. Don't know if others would find this feature useful. Rajat. On Thu, Feb 23, 2012 at 3:57 AM, 陳韋任 che...@iis.sinica.edu.tw wrote: Hi Rajat, Great work!

Re: [Qemu-devel] arm-linux-user, i386-linux-user: Make QEMU act as TCG compiler
Hi Peter, Would QEMU developers be interested in integrating this TCG compilation functionality that I have been working on into later releases of QEMU? The patch I have right now breaks the original emulation but if there is some interest in supporting static compilation into TCG in the future, I can submit a clean patch which does not break emulation but instead adds a run-time option to generate TCG compilation. I would be grateful if you could let me know. Many thanks in anticipation. With warm regards, Rajat. 2012/2/23 Rajat Goyal rajat.go...@cl.cam.ac.uk QEMU as a dynamic translator is already available.

To be honest I don't see any general utility in it, and refactoring everything to be able to do anything resembling this cleanly would be an enormously painful upheaval. -- PMM
