Re: [ts-7000] TS-7200 / ARM9 speed issue - question

The default Debian distro and TS toolchains do not no, they generate hardfloat calls which fail then get recalled softfloat.

Well the big problem is that it assumes a FPU, sends the instructions
to the FPU (which is does have but isn't supported by default), those
instructions fail, causing the kernel to have to re-issue instructions
to emulate a FPU.  This whole thing takes _forever_, if the distro was
built with softfloat it wouldn't be as bad, and if built with Mavric
Crunch would be even better.  You can of course, rebuild the distro
with EABI  or softfloat if you want, there's a few people on here
working on that.

    

Hmm.  Are you sure about that?  Won't GCC just generate inline code (or
function calls) if you specify that there is no floating point unit?
