Re: Alpha Cross compiler

[Wang Baisheng <baisheng dot wang dot cn at gmail dot com>]

Check the output, the cross compiler chooses correnct cross as...

I think you can try:

1 Add a "-S" to CFLAGS to produce the assembly code, and double check it.

2 What about writing an hello assembly code including instruction
"movl", using alphaev67-unknown-linux-gnu-as try to compile. And what
will happen ?
