BTW my policy on patches in crosstool is that they have to be suitable for submission to gcc mainline. Thus I can't include any patches that change gcc to default to softfloat.
Of course, this is very reasonable. This is the default that the gcc maintainers have chosen; I think I've read somewhere that a lot of prepackaged ARM Linux distributions also use this float format, so changing it could be quite disruptive.
For most people, using an ARM kernel with an emulator will hopefully be good enough. In my particular situation though, I simply knew that I would build everything from scratch, for a machine without FPU hardware, so that was why I made a softfloat-by-default patch.
What I would love would be the best of both worlds: a patch that made it easy to select softfloat-by-default. That way you could use an unpatched gcc, and just configure it with this new option.
That would benefit you, too, since then you wouldn't need to patch gcc anymore. - Dan
