64 Core processors with Linux development tools

Was going through TILE64™ PROCESSOR FAMILY from Tilera Corp.

A 64 core architecture. I got impressed by reading because i think this is one way to future. everybody like to be back to RISC architecture and the RISC models getting more attention.

Compile hello.c in steps

How ?

hello.c
=======

#include

int
main (void)
{
printf ("Hello, world!\n");
return 0;
}

one way to do : "gcc hello.c "

Lets do it step by step :

cpp hello.c > hello.i

hello.i will have all macros expanded.

gcc -Wall -S hello.i

check for hello.s - yep its assembly language code

as hello.s -o hello.o

Now Object file time, created object file using -o option

now ld time but LD need to have a lot options so lets go for

gcc hello.o

this links and create a.out

run a.out and see "Hello, world!".

too long ?? k just use --save-temps options in gcc, all temp files will be saved

'gcc --save-temps hello.c' and do an ls after :-)

tools for help:

file : identifies the file type and some of its characteristics
nm : shows symbol table
ldd : shows list of shared libraries an executable needs
