Good morning, I'm new to gentoo-embedded.

I'm trying to create a toolchain for powerpc-e500v2-linux-gnuspe.

I have created (but not tested) a toolchain for powerpc-e500v2-linux-gnu.
However, when I'm trying to create powerpc-e500v2-linux-gnuspe, I get the
following error while compiling glibc:

../sysdeps/powerpc/fpu/fclrexcpt.c: In function ‘__feclearexcept’:
../sysdeps/powerpc/fpu/fclrexcpt.c:29:12: error: impossible constraint in
‘asm’
../sysdeps/powerpc/fpu/fclrexcpt.c:36:3: error: impossible constraint in
‘asm’
../sysdeps/powerpc/fpu/fclrexcpt.c:36:3: error: impossible constraint in
‘asm’

I attach the logs.


I also tried to create a toolchain for powerpc-softfloat-linux-gnuspe, as
it would at least partially meet my needs, and also failed, albeit with
different errors:

I also attach the logs for that case.

Am I doing anything wrong?
