[Qemu-devel] [RFC PATCH for 2.11 01/23] softfloat: move existing softfloat2a into versioned directory
Posted by Alex Bennée 8 years, 5 months ago 
This is a precursor to importing SoftFloat3c into the QEMU source
tree. As the two versions of SoftFloat present different APIs the hope
is to selectively include the version 3 header when required. So for
this change:

 - #include "fpu/softloat.h" -> #include "fpu/softfloat2a/softfloat.h"
 - fpu/softfloat* -> fpu/softfloat2a/

This is all pretty mechanical and doesn't yet change any capabilities.
