News and articles from around the web
I didn't spot any particular LLVM-related news or blog posts this week, but as always I greatly appreciate people sending in tips. As this is the first issue of the new year, LLVM Weekly has hit another milestone. Issue #1 was published on January 6th 2014, so we've now hit 7 whole years (and still without missing a single week!). Thank you everyone for your support.
