Yes and no. My feeling is that people are forced to the softfloat
patch(es) since gcc3 is pickier about compiling options: many people
complain about the compiler telling them that libgcc's integer(!)
routines are not compatible with the application (typically
bootloaders or the kernel). Just because different -mXXX-float were
used.

Personally, I have decided not to use the softfloat patch just yet.
The only problem I ran into was compiling u-boot, and there I just
drop the -msoft-float (with care and grinding teeth, admittedly).

BTW Dan, have you tried the softfloat patched gcc on an ARM V4 system,
ie. _not_ XScale?

Marius
