Hi,
I made an extension of the alpha backend. To make it cleaner I have
created another backend directory (in gcc/config/mtalpha). I updated the
configure scripts and binutils accordingly (with the new path, name
"mtalpha", features of my extension).
The problem is when I generate the compiler (as a cross-compiler on my
x86 machine), I have the following errors while generating the libgcc:
