Hi,
I've recently been using a target (e200z6) where a "-mno-spe
-mabi=no-spe" libgcc was required.
The closest combination provided by 4.9.1 was "-mno-spe -mabi=no-spe
-mno-isel". My builds disable spe, but leave isel enabled.
Unfortunately, with this combination of options gcc uses an incompatible
libgcc which includes spe instructions.
I have attached a patch which enables the "-mno-spe -mabi=no-spe" multilib.
It seems a bit broken that gcc would use an spe version of libgcc when I
specify "no-spe".
Hopefully someone finds the patch useful.
Kind regards,
Patrick
