detecting long multiply overflow

by Edward Nevill

Hi, Does anyone know of a nice way to detect 64 x 64 -> 64 multiply overflow on aarch64? On x86 you can just use the V flag, but aarch64 seems to have no option to set the flags after a MUL instruction which I find very odd. The only solution I can think of is to do the equivalent of r = a * b; if (r/a != b) overflow(); There is some short circuiting you can do to avoid the div if you know there is no possibility it could have overflowed. Eg. if (clz(labs(a)) + clz(labs(b)) < 32) { r = a * b; if (r/a != b) overflow(); } Then there is the special case of a = 0x8000000000000000 and b == -1. All in all its a mess just to detect overflow. Regards, Ed.

Redistributable ARM Mali GPU binary drivers

by Siarhei Siamashka

Hello, In the Q & A session at the AnandTech website, Jem Davies promised to deliver the redistributable binary drivers for the Mali GPU via Linaro, or at least he liked this idea very much: http://anandtech.com/comments/8226/ask-the-experts-arm-fellow-jem-davies-an… Does anybody have an estimate when this is going to happen? Or if this has already happened, could somebody help me to navigate the Linaro website to find the binaries accompanied with the appropriate license, which explicitly permits redistribution? So far I could only find the presumably outdated notices stating that "Ubuntu flavoured images released as Linaro engineering builds are not for production use, modification or redistribution, but are to be used for evaluation purposes only". Thanks. -- Best regards, Siarhei Siamashka
