This is the gcc side of the patch.

[LLVMdev] llvm.atomic.barrier implementation
Attached is the target independent llvm.atomic.barrier support, as
well as alpha and x86 (sse2) support. This matches Chandler's
definitions, and the LangRef patch will just restore that. Non-sse2
barrier will be needed, I think it is "lock; mov %esp, %esp", but I'm
not sure.
Any objections? I'll take a hack at the front end support for
__sync_synchronize after this

But that said, it uses a load-locked, store-conditional and has
various memory barriers which are sufficient to implement all your
proposal.

[LLVMdev] Union type efforts and ComputeLinearIndex
I just looked over your diff and it would seem to me that additional changes would be needed to be done to some of the LLVM-IR -> DAG stuff to make things fully functional (this could be a bit of supposition on my part since I do not fully understand all of the code).

[LLVMdev] compile linux kernel
does that mean .o generated with gcc (.c -> .s and .s -> .o) will not
contain llvm ir?
i meant, final kernel bitcode ir arch independent and can be JIT with
any arch-specific backend. Is it not the case?
thanks,

[LLVMdev] Adding support to LLVM for data & code layout (needed by GHC)
Its good to see that a feature of this nature would be useful to a

[LLVMdev] Data Structure Analysis
I updated the latest "poolalloc" code and the problem seems to have been fixed.
However, I am still having problem of running "poolalloc".
After compilation finished, there are several dynamic libraries
created (libpoolalloc_rt.so, libpoolalloc_fl_rt.so and
LLVMDataStructure.so). I was not sure which one I should use so I just
tried all of them with "opt -load".

Hi Andrew,
Why create opaque types to avoid something that should be taken from
granted (in a said "type-safe" representation)?

[LLVMdev] Data Structure Analysis
DSA should be current against head, but poolalloc isn't. I've changed
DSA a bit so it may not compile with poolalloc as is. I haven't had
time to tackle updating poolalloc (either to head or to the dsa
changes). If you want the version from the paper, try checking out
llvm 1.8 or 1.9 and a dsa from around then. The dsa as used on the
linux kernel and in the OS work is in a branch

[LLVMdev] Static Profiling Algorithms in LLVM
Hello Kapil,
I have implemented a static profiler for LLVM as a google summer of
code project in 2009. I wrote it for the 2.4 branch, but the
implementation never made into the tree. I have recently ported it to
LLVM 2.8, but I haven't tested it. You can take a look at the code
from: http://homepages.dcc.ufmg.br/~rimsa/tools/stprof-llvm.patch
The implementation is based on Wu's

in case you're interested in having llvm in debian sarge: it was removed
