Thanks for the info. I had no idea which kind of SoCs where those. This look pretty old indeed.

vfpv3-d16 is the default FPU setting in the Debian toolchain. I think Marvell is one of the SoCs supported by Debian.


Likely the machine where the GTK+ bot runs supports something better than that. The thing is that Debian defaults to --with-fpu=vfpv3-d16 and we are using the compiler defaults.

I guess the best thing we can do here is to detect on CMake if the compiler supports a FPU with 32 VFP registers and pass the right -fpu flag. If it doesn't then disable MASM (and JIT).
