  Did you try using the 'strip' command from binutils on the output ? You'd
be surprised how much difference it might make.  It will be the main reason
why your exe is so large.

  Yes, but each of those files is very small; by and large, each one
contains
just one or two functions, for this very reason: so that only the minimum
that
needs to be linked in will be.  Looking at your list, it's got things like
malloc and free, open, close, read and write; I assume your program wants to
use these functions ?

Instead of strip, look at it with 'objdump --section-headers'
<foo.elf>.  This will tell you the size of each of the sections in the
executable(and where they are loaded) without losing any of the
symbols from the executable.

Thanks.
I have tried "the strip" : I obtained an executables file of more than
110000 bytes.
But the "objdump --section-headers" gave me :
Sections:

LMA       File off  Algn
  0 .textrom      00000060

CONTENTS, ALLOC, LOAD, READONLY, CODE
If I add all the section sizes, I obtain 0x367c = 13948 bytes.
But the total size of the executable file is explained by the file offset
which is increased of 0x8000 = 32 Kbytes each time the section is put in
a new memory region  (I have three memory regions defined in my linker
script : 1 rom and two separated ram.
I do not understand what is the interest to align the file offsets
(for different memory regions) to such segment size for a cross executable
file. I searched a linker option/command to control this file alignment
and I found only the PHDRS script command that allows to set the "program
headers" (or "segments") of the ELF object file format.
The "objdump -p" gave me the following "program headers" :
Program Header:
    LOAD off    0x00008000 vaddr
0x00000000 paddr 0x00000000 align 2**15

memsz 0x00000060 flags r-x
    LOAD off    0x00010000 vaddr

memsz 0x00002c14 flags r-x
private flags = 0: [interworking not enabled] [APCS-32] [floats
passed in integer registers] [absolute position]
Does any know if I can put all my sections in the same program header
? How can I start this program header to the minimal value ?

I found how to avoid the page-alignment, reducing the LOAD offset of each
program header to the minimum. The --nmagic (the -n option does not seem
to work) of the linker turns off the page-alignment. The ld.document about
this option says:
-------------clip---------------------------------
`-n'
`--nmagic'
     Turn off page alignment of sections, and
mark the output as
     `NMAGIC' if possible.
-------------clip---------------------------------
And now I obtain:

Build a short executable

[Pierre Saucourt-Harmel (r54698)]

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 6879 bytes --]

Hello everybody,
I am trying to build a short program for a stand-alone ARM 7 processor
(without any OS), from a Solaris work station.
I generated sucessfully binutils-2.10.1, gcc-2.95.2, newlib-1.8.2 and
gdb-5.0.
I made a crt0.S (but refered to the default crtbegin.o). All my files
(*.c and crt0.S) explicitely call the external memset () and strlen ()
functions.
I removed the -g option to generate the cross libraries (libg.a and
libgcc.a) but not for my small files. I used -o2 everywhere and I obtained
an executable file of 132656 bytes !
With the generated map, I noticed more than 20 objects files coming
from libg.a and libgcc.a were *fully* loaded in my executable.
The linker processing that makes the symbol dependencies of the object
files (coming from libg.a and libgcc.a libraries) does not focus on which
function is used and which is not. The function dependencies and loading
seem to stop at the object level but not at the function level.
Is it possible to load what is strictly necessary ?

Build a short executable

Hello everybody,
I am trying to build a short program for a stand-alone ARM 7 processor
(without any OS), from a Solaris work station.
I generated sucessfully binutils-2.10.1, gcc-2.95.2, newlib-1.8.2 and
gdb-5.0.
I made a crt0.S (but refered to the default crtbegin.o). All my files
(*.c and crt0.S) explicitely call the external memset () and strlen ()
functions.
I removed the -g option to generate the cross libraries (libg.a and
libgcc.a) but not for my small files. I used -o2 everywhere and I obtained
an executable file of 132656 bytes !
With the generated map, I noticed more than 20 objects files coming
from libg.a and libgcc.a were *fully* loaded in my executable.
The linker processing that makes the symbol dependencies of the object
files (coming from libg.a and libgcc.a libraries) does not focus on which
function is used and which is not. The function dependencies and loading
seem to stop at the object level but not at the function level.
Is it possible to load what is strictly necessary ?
