I like a lot of the premise behind LLVM, in terms of having the
advantage of a newer architecture that GCC doesn't, having more
informative error messages, and a better customisation/plugin
architecture. For these reasons, I'm pretty excited about seeing this
in Haiku development.
However, I don't appreciate the reasons for people pushing for LLVM as
a backlash against the GPL. We can all have our licensing
disagreements, but I just don't think something like the GPL should
cause anyone to "hate" GCC. But, I digress. :)
I'd be interesting in trying llvm native builds in Haiku for test
building some new 3rd-party apps. I'm planning on writing a few
during a "coding holiday" (since my work will force me to use vacation
time :P).
Thanks for the info!
