Agreed, as long as armv5tel remains supported. > Things I think we should consider as a minimum: > > *). Little endian (obviously, but worth stating) (l) > *).

I think NEON is one step too far because Tegra doesn't support it, and Tegra is rapidly becoming very prolific in convenient form factors, such as these: http://www.trimslice.com http://uk.computers.toshiba-europe.com/innovation/jsp/SUPPORTSECTION/discontinuedProductPage.do?service=UK&toshibaShop=false&BV_UseBVCookie=yes&PRODUCT_ID=1091301&BV_Script=/jsp/fixup/productPage http://www.motorola.com/Consumers/GB-EN/Consumer-Products-and-Services/Mobile-Phones/ci.Motorola-ATRIX-GB-EN.alt > I think we should build for ARM (as opposed to Thumb2) but we should > support interworking with Thumb2 code through the toolchain options.
