TableGen - cryptic error messages (~feature request)
Hello.
I started implementing a back end in LLVM (and I'm writing some hints I consider
useful at https://sites.google.com/site/alexsusu/home/backend-llvm ).
Unfortunately, I hit quite a few times very cryptic error messages when compiling
with TableGen, which required a few good hours of debugging the TableGen program.
The most cryptic error message was when compiling with

[GSoC] Supporting Efficiently the Shift-vector Instructions of the Connex Vector Processor
Hello, Anton,
I'd like to add a small reply regarding this GSoC project that I would like to mentor
and I discussed also with Andrei.
A good part of our GSoC project is indeed related to this Connex back end that it's
not yet part of the LLVM source repository - an important thing proposed in the project is
that we plan to perform efficient realignment for this Connex vector

Problem with sync user account from Samba Master to Samba Slave
Hello,
i?ve Samba 4.7 with domain controller with 3 servers, 1 master (samba-ad) and two slaves (samba-slave1) and (samba-slave2).

Vif only accepts connex after talking out of domain.
My domains dont see any traffic until you try to connect out
from within the domain. Tried this several times and it was
consistent. I have no firewall either. running each domain
on different cpu probably doesn''t help, although Im no
network expert.
Here is some info.

Instruction selection problem with type i64 - mistaken as v8i64?
Hello.
I am writing a back end in which I combined the existing BPF LLVM back end with the
Mips MSA vector extensions (from the Mips back end)
I have encountered an error when compiling with llc: the instruction selector uses a
vector register instead of a scalar register with type i64 .
I have the following part of LLVM IR program:

Scalable Vector Types in IR - Next Steps?
Hi Alex,
We've only recently managed to get the core scalable vector IR type into the codebase (so it will be present in 9.0); that allows you to write IR with scalable vector types, but there's no backend able to generate code for it yet, and as you mention no support for stepvector (or vscale). Arm will start upstreaming those soon.

LLVM IR intrinsics placeholder for strings [was Re: Back end with special loop instructions (using LLVM IR intrinsics)]
Hello.
I come back to this thread. But I want to ask a slightly different question.
Is there a way to have LLVM IR language intrinsics that are given at construction
time a string that is written at assembly generation time as it is? (so, basically having
placeholders of strings in LLVM that remain untouched until the end, including code
generation time.)
More exactly, I would

BPF backend with vector operations - error "Could not infer all types in, pattern!"

PDC Migration to Samba
Hi
I've been trying to finally switch off our NT4 PDC over the last few months
and transfer PDC duties to our Samba file server. Although I have no
difficulty in getting the Samba box to authenticate users as the PDC, I have
never been able to migrate the user's settings over. As far as the clients
(NT4 and W2K) are concerned, users effectively start with a "clean slate"

Specifying conditional blocks for the back end
Hello.
For my back end for the Connex SIMD research processor I want to implement
conditional blocks (I guess the better term is predicated blocks). Predicated blocks are
bordered by two instructions WHEREEQ (or WHERELT, etc) and ENDWHERE.
For example, the following code executes the instructions inside the WHERE block only
for the lanes where R0 == R1:
EQ R0, R1;

Scalable Vector Types in IR - Next Steps?
I had a phone conversation yesterday with Graham, Francesco,
and Kristof.
There is one more reason to go with the native type change:
ARM has already written the code with the SV types, and they
have patches ready to be reviewed and integrated in LLVM.
As I don't want to stand in the way of getting SVE in LLVM
as soon as possible, I will also support the integration of the
existing patches

Addressing TableGen's error "Ran out of lanemask bits" in order to use more than 32 subregisters per register
Hello.
In my TableGen back end description I need to use more than 32 (e.g., 128, 1024, etc)
subregisters per register for my research SIMD processor. I have used so far with success
32 subregisters.
However, when using 128 subregisters when I now give the command:

voipbuster advise
Hi,
I'm using voipbuster at work, and I've got 2 questions:
1) Is it possible to send faxes using voipbuster connex?
2) Is it possible to cut off or cover the voice that say the charge
per minute?(I've payed the '5' euro, and from that moment I've got
it!).
Of course I understand that is to let me know how much I'm going to
spend, but I do not like it, expecially when

Instruction selection problem with type i64 - mistaken as v8i64?
Hi,
I vaguely remember hitting something like this when I was implementing MSA. IIRC, there was an optimization (in DAGCombine or somewhere around there) that was folding CopyToReg instructions into the load without checking whether the new register class was acceptable. I remember adding a target hook to limit this optimization based on the EVT's involved but I'm not sure if that's

BPF backend with vector operations - some strange error

I've tried to add some simple arithmetic vector operations to the BPF backend
available in the LLVM repo. Because I added in BPFRegisterInfo.td another RegisterClass

(sequence "W%u", 0, 31)>;
