Hi port-arm,
I'd like to report someting since I got a little step.

I looked into src/bin/sh/ sources and made some test, and found
memcpy()'ed area has garbage data.
Then, I rebuilt libc to see what happens with C sources of memcpy() in
src/lib/libc/string/, instead of assembler version in
src/lib/libc/arch/arm/string.

This change made really a difference.
At least, there was such an improvemnt that now I can invoke any
command in $PATH (ls, mount, etc.), however, output from any commands
are still like garbage....

I also made a small program crunched with md-root just to printf some
short string, that still prints garbage on stdout :-(

I think there's someting wrong in src/lib/libc/arch/arm/string/*.S,
correct ?
But I cannot assert, as I'm not familiar with arm assembly language...
I wonder somebody arm expert could examine them...

# I'm sorry It's very hard for me to write English message...

Best Regards,
Shoichi Miyake
