Hello,

Using '--show-lma' could get VMA and LMA details.
Can you suggest options to print 'File off' and 'Alng' with llvm-objdump?
Thank you in advance.

Hi Holger,

LLVM represents debug info as explicit calls to intrinsics.
This approach has many advantages, but a possible disadvantage
is that it can significantly increase the size of the bitcode.
I don't know if that explains your observations.

I want to share a little LLVM experiment.
I tried LLVM on one of my bigger Qt 3.x based projects. I used
llvm from SVN trunk (r39999) and SVN llvm-gcc-4.01 (r370) and
did compile every file with
/usr/src/llvm/dist/bin/g++ -c -pipe -g \
-Wall -Wextra -Wno-sign-compare \
... lots of -Dxxxx ... \
--emit-llvm -I/usr/share/qt3/mkspecs/default \

Ayuda con el paquete de text mining (TM)
Estimados, les escribo para consultar, lo siguiente:
Estoy haciendo un trabajo de text mining y necesito importar una serie de
textos para preprocesarlos, es decir eliminar los Stopwords, hacer stemming,
eliminar signos de puntuación etc. Esto último lo puedo realizar con los
datasets que trae la librería TM. Lo que no puedo lograr es importar texto

Putting this in the paravirt framework is overkill IMO. There is no need
to patch the callsites for optimal performance.
I'd put it into struct x86_hyper_init and pre-init it with x86_init_noop

[PATCH 0/15] adjust pvops to accomodate its x86_64 variant
Hi folks,
With this series, the bulk of the work of pvops64 is done.
Here, I integrate most of the paravirt.c and paravirt.h files, making
them applicable to both architectures.
CONFIG_PARAVIRT is _not_ present yet. Basically, this code is missing page
table integration (patches currently being worked on by Jeremy).
Enjoy

This changes the pv ops code generation to more closely match reality.
