Hi all,
I have this function defined twice. One in the libgcc2.c file and one in
gcc/config/arm/ieee754-df.S
__floatdisf
I have problem during compilation of a arm soft float toolchain. Is
there any fix?
Regards Michael
The build system should only be using the latter. What configuration
are you using? And what version of gcc?
R.
