[LLVMdev] Description Linear scan
Hey, guys, could someone tell me some high level things about the version of linear scan that you use? 1) The heuristics for spilling seems to be: (mop.isUse() + mop.isDef()) * pow(10.0F, (int)loopDepth besides not spilling defs that are immediatly followed by uses, do you do any other thing, such as, taking into consideration the size of the interval when spilling? 2) How do you

It makes the assertion fails: MachineOperand& MO = inst.getOperand(n); if (MRegisterInfo::isVirtualRegister(MO.getReg())) { assert(MachineOperand::MO_VirtualRegister == MO.getType()); ... } Is that alright?

[LLVMdev] [Query] Programming Register Allocation
Thanks for the information. I still don't know how do I partition registers into different classes from the virtual registers? For instance, I have the function who which iterates over the instructions, but I don't know how to write the function which returns the different register class. void RAOptimal::Gather(MachineFunction &Fn) { // Gather just iterates over the

Any ideas?

[LLVMdev] Regalloc Refactoring
Hi all, As I work toward improving LLVM register allocation, I've come across the need to do some refactoring. Specifically, I would like to separate register coalescing from live interval analysis. Right now LiveIntervals handles both. The reason I want to separate them is that other types of register allocators might like to do coalescing differently (e.g. graph coloring does it by

[LLVMdev] Simpler subreg ops in machine code IR
I am considering adding a new target independent codegen-only COPY instruction to our MachineInstr representation. It would be used to replace INSERT_SUBREG, EXTRACT_SUBREG, and virtual register copies after instruction selection. Selection DAG still needs {INSERT,EXTRACT}_SUBREG, but they would not appear as MachineInstrs any longer. The COPY instruction handles subreg operations with less

Hola Carlos: -Mira, mi máquina es nueva, con 16 giga de memoria Ram, así que no creo que sea problema de recursos -En general me pasa esto cuando despliego un Plot.

encontrar fechas saltadas
Hola, Usé "textConnection" para poder utilizar tus propios datos y leerlos con read.table. En tu caso, si tienes los datos en un .csv, simplemente tienes que leerlos con read.table y utilizar la parte que sigue a "library(lubridate)" en el código que compartí ayer: coger la columna de fechas, leerla con "lubridate" y compararla con el vector de referencia.

problemas con rBIND con distintos número de columnas
De esa forma me sigue entregando lo mismo, multiplica las variables por dos (80 obs 26 variables) debería ser (80 obs 13 variables).En concreto pega la información pero la costado, no hacia abajo. Solucionara el tema si le agrego dos columnas ficticias para que queden todas las bases con 13 variables? Saludos. [Descripción: FIRMA2] De: Carlos Ortega [mailto:cof en qualityexcellence.es] Enviado
