>Description:
__aeabi_unwind_cpp_pr0 and __aeabi_unwind_cpp_pr1 are not defined in any

There are required to build pkgsrc/www/firefox.

I have no idea.
I have heard that Linux/ARM has these symbols in libgcc_eh.a.

Thanks for your information.
But /usr/bin/as has these symbols.
Is this intentional?
If so, why unused symbol is used by /usr/bin/as?

If you use ARM EHABI annotation, as will create the corresponding ARM
specific output. That's intentional.

Thank you very much.
yuv_row_arm.s uses .fnstart/.fnend. They are unwind aware directives.
They should be removed or so.

I'll take care of it once I am done with cwrappers.

Thank you.
Another problematic file is
xpcom/reflect/xptcall/md/unix/xptcstubs_arm_netbsd.cpp ,
and it has .fnstart/.fnend in its inline asm.
I will try to define them only under Linux.
I will restart www/firefox build on evbearmv7hf-el.

Take a look at devel/libffi.

devel/libffi/patches/patch-src_arm_sysv.S is insightful.
Thanks for your pointer.
