hi ML
I'm Alessio Terpin a student of Physic of the University of Trieste
(Italy)
for my thesis i wrote down C code using as tool for compiling the gcc
on Red Hat 6.1 Linux platform
The hardware that i have used is
P 200 64M
PMMX 233 128M
K6-2 400 128M
Profiling my code on this platform i have notice
that the same compiled file with Optimization level
machine independent -O1 -O2 -O3
present difference in the cpu consume of the varies function
so i have thought that this depend from the different architecture
of the CPU. It's right or there is some things that i don't have
see. In this case i think that the machine code is for 386
Another question when i use CPU optimization, i have used the same
that are used for compile the kernel what happen ?
Can give suggest where find this info
Thanks in Advance for all help can give me
P.S. Sorry for my English :-)
