Hi David,
I was looking at the xscale subdirectory and noticed
there were no individual copyrights or attributions on the files;
what's the history behind them, who originally wrote them?
I guess that you can blame me. It was a long time ago, but I think that
what actually happened was that someone at Intel asked us (Red Hat) to
provide some hand written assembler versions of the string and memory
functions in order to speed up the xscale targeted version of the
arm-elf toolchain. I wrote them and later contributed them to the newlib
project, but it was very remiss of me not to include copyright notices
on the files.
I believe however that it is safe to assume that since I was working for
Red Hat at the time, the sources are covered by Red Hat's blanket FSF
copyright assignment.
