[illumos-Developer] LLVM / clang anyone?

[Antonio Vieiro]

Hi all,

So here we come to the developer list from the discuss list.

We were talking about the LLVM/clang compiler, that promises faster 
compile times [1], that has been recently awarded with the SIGPLAN 
Software Systems award [2], and that is able to compile the FreeBSD 
kernel [3] (but not all BSD ports yet).

It seems LLVM 2.8 does not support Sparc 64 (but does support Sparc 32), 
do that is a problem.

Garrett wisely said in the discuss list that

 > I'm very supportive any effort to support new compilers.  However, we
 > will not be adding new "shadow" compilers, and we will need to retain
 > support for the compilers we already have.  I want to enable choice,
 > without forcing pain and suffering on other people.


Cheers,
Antonio

Hey guys, can I recommend that we take the discussion of compiler
issues, and other "developer" style technical issues to
developer at lists.illumos.org?

I like the conversation, but I think it makes sense to keep in the right
list.
