DSP16xx Target

[Guilherme de Lima Ottoni <ottoni at ic dot unicamp dot br>]

I'm trying to compile GCC with target DSP16xx, but, surprisingly, I got
some compiler errors during compilation. For example, in the file
'dsp16xx.c', I got the following error messages:

...
../../combined/gcc/config/dsp16xx/dsp16xx.c: In function
`print_operand':
../../combined/gcc/config/dsp16xx/dsp16xx.c:1666: warning: implicit

make[1]: *** [dsp16xx.o] Error 1
make: *** [all-gcc] Error 2


In the dsp16xx.c file, there are the following code lines:

...
1676:  	  else if (letter == 'h')
1677:	    fprintf (file, HOST_WIDE_INT_PRINT_DEC, val);
1678:     else if (letter == 'U')
1679:	    fprint(f file, HOST_WIDE_INT_PRINT_HEX, (val >> 16) & 0xffff);
...

It's clear that there is a mistake in line 1679. It's worth saying that
I'm compiling GCC 3.0, but the dsp16xx.c file downloaded from the CVS is
exactly the same. So, I'm trying to understand what is going on. 
Has nobody ever used this target? 

I fixed this error (and I think some others), but then I got compiler
errors because the Makefile also have some problems and I gave up.

Can anybody help me?

Thanks in advance,
