Yes, I'm sorry I didn't make this clear. That is exactly what I did.
The "old" tools were arm-elf, the new "xscale-elf" (the processor is a
Marvell PXA320, an Xscale proc).
Still, the arm-elf floating point code ran very well on it, and I'd
like to understand better how to get that same performance out of my

You mean, rebuild my toolchain with --target=arm-elf, or can I pass --
target to GCC in my target code makefile?
