Hello everyone, First of all, for those of you who went to BSDCan, I hope you had a pleasant flight/trip back home. :-)
On Saturday I went to the LLVM talk (see http://llvm.org/), which I really enjoyed. On Friday Remko Lodder and I already talked with him about the LLVM project. I was excited about the project, so I decided to give it a try at the office. At first I tried LLVM 2.2 with LLVM GCC4 4.2 from Ports, but it didn't work like expected. I won't go into many details about it. When I discussed the problems I was seeing on my system at the office, someone pointed me to the beta tarballs of the upcoming version 2.3, which I installed by patching our FreeBSD port. http://llvm.org/prereleases/2.3/ As an ideal benchmark, I decided to compile an i386 kernel using the LLVM 2.3 snapshot. I didn't expect it to happen, but it works! I was capable of successfully booting into single user mode and shutting it down safely. There is one problem however: http://llvm.org/bugs/show_bug.cgi?id=2267 For some reason, the inline asm support of LLVM is incomplete and causes compilation errors when generating some of the atomic functions in i386/include/atomic.h (lines 262 to 265). To work around this, I made the functions non-atomic. Silly, I know, but it was good enough to perform some basic tests. I think it would be nice if LLVM would once become our standard C compiler. LLVM currently uses GCC as its frontend, which proves to be somewhat compatible with the original GCC> -- Ed Schouten <[EMAIL PROTECTED]> WWW: http://80386.nl/
