What are the options i have to give for compiling the
program for ARM926EJ-S cpu ?
The options right now i am using is
-msoft-float and -mcpu=arm926ej-s.
The toolchain what i am using is gcc version 4.2.1
(Sourcery G++ 4.2-107).
Using "-mfpu=vfp -mfloat-abi=softfp" instead of "-msoft-float" will
enable VFP hardware floating-point code-generation for your program. The
run-time libraries will still use software floating-point. Routines
compiled for VFP are compatible with software floating-point.
Is there any optimized toolchain for floating point
library for this particular cpu ?
Yes, Sourcery G++ Professional offers VFP optimized run-time libraries.
Cheers,
Carlos.
