Sergi, All,

On 2015-11-28 15:55 +0100, Sergi Granell spake thusly:
> gcc differentiates the mpcore-with-vfp from the mcpore-without-vfp
> CPUs. The former is named just 'mpcore', while the latter is named
> 'mpcorenovfp'.
> 
> We only add one entry, 'mpcore' and let the user select whether or
> not to use the VFP. We then name the CPU according to the user's
> selection.
>
