checkout this cross compiler FAQ site
http://www.sthoward.com/CrossGCC/
also find out if mc68K platform is supported on gcc. you can
do that by checkig out the list of supported platforms on 
the gcc.gnu.org site.

gcc porting

[Shripad]

hi..
  well i am trying to configure gcc to produce code for a mc68000 machine on
my intel machine.
The target is a posterminal... with a os called verix ( unix type) os..
I am trying to configure gcc ... so that it generates the object code which
can be linked and the executable loaded on to the pop terminal
The pos terminal has a mc68k processor... i hope i am clear now..

please help...

The GNU config.* haven't heard of verix.

You can build OS-neutral cross compilers which just target a specific
object format, e.g. m68k-elf or m68k-coff; probably your best bet would
be to find out which object format verix uses and then build a
cross-toolchain to target that. If you have system headers and C
libraries for verix then you should configure --without-newlib and drop
those into the build.

If you don't have system headers and libraries then you can use newlib
instead but you might have difficulty interacting with the system.

Good luck,
Rup.

Gcc porting

[Alexander Shkurko]

Hello!

I need your help.

I'm trying to port GCC for one embedded system powered by ARC processor. 
Memory unit of this system has some limitation. It can't use byte 
input/ouput instructions.

So i need to force gcc to use instead of single ldb or stb instuctions a set 
of instructions, but there is only one string for each assembler instruction 
in arc.md file.

Is it possible to force GCC to use several instructions instead of one or 
not?

Thank you for your help.



Yours Sincerely
Shkurko Alexander
