No, the first time I presented the benchmark results in the meaning I had 
added -XX to the FPC parameters but actually I had not.

Compile with

fpc -k--gc-sections libnude.pas

Every FPC program or library contains system.o which is 710KB before strip.
It seems that -XX does not work with "library" so the --gc-sections linker 
command must be supplied to the linker directly.

"
fpc -XX -s prognude.pas
"
produces ppas.sh:

===
#!/bin/sh
DoExitAsm ()
{ echo "An error occurred while assembling $1"; exit 1; }
DoExitLink ()

Note the missing --gc-sections.

Hello Martin.

In a other topic, they talk about to use : -k--gc-sections.

Do you refer to

I worked many years with PIC16xxx. Programming always was done in assembler.

Hello Martin.

Hum, sorry but I am a little bit loosed...

Do you mean that you have a trick to do smartlinking working for libraries ?

So what is the conclusion, what is the trick ?

Thanks.

Yes. That's my compiler. It has only basic features. The idea is to integrate 
the PIC12F and PIC18F series, a simulator, a burning software and a debug 
integrated.  But it will be later.

By now it's a very optimized compiler. It's better than some other commercial 
products.
