Problem talking to SSH 2.3.0 server
I'd like to report a problem I found with the OpenSSH client talking
to the SSH 2.3.0 server.
client: i686-pc-linux (Debian 2.2, kernel 2.2.18pre19, glibc-2.1.3),
SSH-2.0-OpenSSH_2.3.0p1
(built by me from source, but the same problem occurs with
ssh_2.2.0p1-1.1 as shipped with Debian 2.2).
server: sparc-sun-solaris2.7,
SSH-2.0-2.3.0 SSH Secure Shell (non-commercial)

portmap & tcpwrappers
I don't know if this is RedHat 5.1 specific, but be aware that the version
of portmap distributed is the enhanced (Wietse Venema) version. That's
great, except for two things. The first is documented, but easy to overlook:
"In order to avoid deadlocks, the portmap program does not attempt to look
up the remote host name or user name...The upshot of all this is that only

LLVM Backend Issues
Thanks Anton and Krzysztof!
Here is the dump using the -debug flag. At this point I am not making much
sense of this, would it be too much to ask if one of you could walk me
through one of these lines?
One thing that I didn't point out is that I never defined any separate
floating point registers, not sure if this will pose any issue?
Thanks again for your time!

Where is OpenSSH 2.5.0p1?
Hi,
it seems the 2.5.0p1 announcement on www.openssh.com went out a little
bit too early ;). Just curious, why 2.4 was skipped? I don't believe
this is just to have a higher version number than the competition ;).
I see 2.5.0 is there, but no 2.5.0p1 yet even on ftp.openbsd.org itself.
Looking at the CVS tree, I see the two bugs I reported to this list
some time ago (with no response) are

llvm-dev Digest, Vol 166, Issue 22
Hi Krzysztof,
Sure, please see below. DAG.dump.() before and after, annotated with what I
believe the DAG means.
I've spent some time debugging the method but it's proving difficult to
determine where the logic is misfiring. Disabling the entire combine causes
a lot of failing x86-64 tests - I may have to learn an upstream vector ISA
to make progress on this.
Thank you

LLVM Backend Issues
Hi,
I am having issues running a new backend that I created for a new
architecture. I suspect these errors may have something to do with how I
have the string setup in LLVMTargetMachine() below?
Also - It would be great if someone could point me to a document that
describes some of these error messages? For example what does t26 ..t4 mean?
Thanks in advance for taking your valuable time to help

Question about 'DAGTypeLegalizer::SplitVecOp_EXTRACT_VECTOR_ELT'
Hi All,
I have a question about splitting 'EXTRACT_VECTOR_ELT' with 'v2i1'. I
have a llvm IR code snippet as following:

Instruction selection gives "LLVM ERROR: Cannot select"
Hello.
I'm writing a back end for a RISC processor (similar to BPF) with a large SIMD unit.
I tried in the last days to make llc compile to SIMD code the following LLVM program:
define i32 @foo(i32* %A, i32* %B, i32* %C, i32 %N) #0 {
entry: ;vector.body: ; preds = %vector.body, %vector.body.preheader.split.split

Store is responsible for zero-extend. This is the policy...

rL296252 Made large integer operation codegen significantly worse.
I see we're missing an isel pattern for add producing carry and doing a
