Thanks! That's really awesome!

Did you manage to build more complex applications? EABI is a bit different from the hardfloat ABI and there may be still bugs lurking in LDC...

Sorry, I didn't see this thread till now, or I could have saved you some time by telling you not to apply the llvm patch on non-Android linux.  Note that you don't have to compile llvm yourself at all, as long as the system llvm has the ARM backend built in, as it often does.

Unfortunately no, I didn't have the time.

I was interested in building audio applications in D, but I do not use much float arithmetic on embedded systems (I prefer integer/fixed-point over it). Anyway I have some pieces of DSP algorithms I could try out in float (FFT, biquads, FIR etc).

I could also try to run the phobos test suite on the board I use, if there is an easy way to do it (I'm pretty new to all this).

Ah ok. I am totally new to llvm. I did it the hard way. :)
