Asterisk sip and radius authentication
Hello all,
I am new in asterisk configuration. I want to configure a Radius server to
authenticate the sip users of asterisk. I have trying to use the next

Can you help me?

TableGen Instruction class Uses and Defs
Hello LLVM-Dev,
I understand that Uses and Defs are for implicit registers. Uses is defined as for using non-operand registers and Defs is defined as for modifying non-operand registers.
For example, for compare and compare with carry instructions, is my understanding correct that the instructions should be defined as described below?
Considering that the carry flag is part of the status

RTLIB and Custom Library calls
Hello LLVM-Dev,
Most of the processing for i64 and f64 types for our backend are emulation library calls. Some of the library calls are not defined in the RuntimeLibcalls.def Libcall enum so we have to define custom library calls.
How is the ideal way of implementing the custom library calls? Providing us with a target backend having a similar functionality would also help us significantly.

LLVM Backend Legalize Phase
Hello Sebastien,
Thank you very much for the clarification. This would greatly help us in our development.
I have noticed that setOperationAction(Expand) does not always work, for these cases, does it automatically mean that setOperationAction(Custom) should be used or not necessarily?
Currently, we perform a pseudo instruction instead of setting it to custom.
For example in the case of a

Function Return Legalization
Hi llvm-dev,
>> The CopyFromReg->CopyToReg->CopyFromReg sequence doesn’t have the chains set correctly: the second CopyFromReg’s input chain isn’t connected to the CopyToReg’s output chain. (This appears to be the same problem in both graphs.)
The DAG mentioned was generated by the SelectionDAGBuilder and as much as possible, we only modify the files within our target so I tried

Function Return Legalization
Hi,
After removing support for the i64 type in the *CallingConv.td, sret-demotion is performed and we now have a store<(store 8, align 1)> DAG node being generated. Please refer to the attached dag_funcret.pdf DAG visualization.
My understanding is that, the second operand(CopyFromReg->Register %1, Register %0 back-up) in the store node is the memory location allocated for the i64 type

Function Return Legalization
Hi All,
In the target we are implementing, function return for i64 and f64 types has a different processing.
For types i8 to i32, and f32, the return values are stored in their designated return registers (like how other targets does it).
For i64 and f64 types, in the function call, after pushing the function parameters into the stack, the address of the allocated return memory space is

Instruction selection phase
Hello LLVM-Dev,
Attached are:
· The DAG after being built
· The DAG before the legalization phase
The DAG illustrated performs a signed division for type i32. As can be seen, the SDIV node was converted to a series of other nodes (which includes a MULHS node). In the target lowering class of our target, the SDIV has an operation action of custom. Does anybody know where in

[LLVMdev] Turning on/off instruction extensions
I applied the patch to the trunk version successfully, although I get an error in between:
1 out of 1 hunk FAILED -- saving rejects to file lib/Transforms/IPO/CMakeLists.txt.rej
Can I ignore the error? The patch exits normally except for that error.
Also, I tried to apply the patch to the LLVM 3.0 but does not work at all. Is the trunk version the only one where the patch can be applied?

Compare ISel
Good day LLVM-Dev,
I hope all are in good health.
We are currently implementing the compare operation for i64 type in our target.
The main difference of the i64 type compare to lower integer types is that it performs a library call instead of generating a compare instruction.
All is good until before ISelDAGToDAG class. We have observed that the difference in a compare operation for i32 and

calculo porcentaje de subcategirías para individuos diferentes
Buenas noches,
Soy nueva en R y a veces me cuesta pensar los cálculos de manera más
práctica, por los que les agradecería la ayuda.

ubicaciones de 39 perros, cada perro tiene poco más o poco menos de 1000

[LLVMdev] RFC: Recursive inlining
Hi,
Apologies for the very late response.
We have manually tried the idea with a very simple Fibonacci sequence code. While being very very simple, the recursion cannot be handled by TRE. Because there are two recursive callsites, it also needs to keep some sort of state across iterations of the "while(stack not empty)" loop.
We get between 2.5 and 8x slowdowns depending on which

Cambiar el intervalo de confianza en un anova
Buenas,
En R, como en la mayoría del software estadístico, no se utiliza ningún nivel de confianza sino que lo que se calcula es el p-valor asociado
al contraste. De forma que cuanto más cerca de 0 esté el p-valor "menos credibilidad le damos a la hipótesis nula". Dicho mejor, debemos
rechazar la hipótesis nula si el p-valor está por debajo de nuestro nivel de confianza.
Por ejemplo,

The attached patch should apply cleanly.
