The arm7tdmi processor from Analog Devices does not have a FPU and I have been
unable to locate an option or flag to prevent arm.o from being created with
"hard-float".
The application I'm porting to the arm7tdmi is mixed mode (arm/thumb).
I would appreciate any hints on how to build libgcc.c with "soft-float" and
"thumb-interwork"
Thanks for your assistance.
