Joel,

Although possibly not fully optimized, soft float configuration for armv4t should still run on armv7.
To build your own, I think you'll have to patch the gcc source code to enable multilib (disabled by default) and build the C library twice and figure out a way to combine them. Not exactly sure of the exact process since it's not something we currently do or support.

Thanks!

Victor,

 

From the wiki, it mentions that the soft float (multilib) configuration supported is armv4t.

If we build our own toolchain for soft-float support based on linaro gcc source, is it just a modification of toolchain configuration? Or it need heavy patch for thing like eglibc?

 

Thank you for quick response!

 

Joel

Hi Linaro-toolchain team,

 

I notice that the Linaro toolchain binary only support hard-float. We have a platform which is ARMv7 based does not support VFP.

Could you generate toolchain binary for ARmv7 that allows soft-float?

 

Thanks,

 

Joel
