stupid linker question....

[Steve Iribarne (GMail)]

I forgot the flag that generates a list file that has both assembly
and c mixed in.

Anyone?

Thanks...

gcc -Wa,-alhs -g main.c >main.cs

  will put interleaved code/assembly into main.cs file.

Re: stupid linker question.... to remove unused functions in the object file.

[Parav Pandit]

Hi,

I have few functions in a C file but those are not
called at present. Even though those function
definitions are part of the object file.
Those will be called later on.

What CFLAGS should I pass to remove unused functions?
I cannot enable -Ox at present to have any
unpredictable behaviour.

Regards,
Parav Pandit

I believe you can use -ffunction-sections -Wl,--gc-sections when you  
compile and link.  If you have binutils prior to 2.16, this only  
works with -static.
