While I have an interest in improving TCG performance I'm afraid there are many more easier wins before tackling a target specific hack for which I'm not familiar. No doubt this thread will be referred to next time someone wants something done about it. > ..Large majority of software don't check for exceptions at all and if > I really want to pursue max precision I'll go for a software > multiprecision library like GMP or MPFR Libraries. However for QEMU we regard failure to correctly emulate the architecture as a bug - we don't code to common software patterns because there is plenty of software out there that doesn't follow it. > So the hardfloats 'should' be set as first choice and only if > instruction requires precision/error check process it in softfloats. Sure but someone will have to do the work to support that. -- Alex Bennée
