Hi Cary & Ian,
thanks for the great work. I already changed all software links in our company to be done by
gold and saw an amazing speed-up in link time (approx. 70%). However the faster linking
goes, the stronger the appetite for more speed becomes ;)
I'm reading the gold sources and http://gcc.gnu.org/wiki/GoldIncrementalLinking and have the
following questions:
* Are there specific areas where I can contribute to incremental linking ?
* I have added a link to http://gcc.gnu.org/wiki/LinkGlossary - is this the right place to
put terms I learned and/or want to share/ask ?
Thanks a lot,
Yinon
