Here's how I configure GCC:
$ /n/08/rask/src/gcc/configure --target m32c-unknown-elf
--with-newlib--enable-sim --disable-gdb --disable-nls
--enable-languages=c,c++,java
This is how to reproduce the failure:
$ ./xgcc -B./ ~/__dprintf.c -S -dp -o /dev/null -mcpu=m32cm
/n/08/rask/src/gcc/newlib/libc/misc/__dprintf.c: In function '__dprintf':
/n/08/rask/src/gcc/newlib/libc/misc/__dprintf.c:73: internal compiler error: in

This is more likely related to pointer_plus than dataflow.
Looking into it.

You shouldn't introduce calls to langhooks. Why not use mode_for_size?

I was just copying code from fold-const.c. I have the mode already, I
need an integer tree type that matches that mode. So really
mode_for_size will not give me any more information.

------- Comment #6 from mmitchel at gcc dot gnu dot org 2007-06-29 18:52 -------
There is nothing wrong with langhooks per se.
The problem is langhooks that influence the interpretation of the IR, not
langhooks that are used to *create* the IR.

Ian Taylor and I found a simpler patch that does not use langhooks, and also
has the virtue of working. ;-) Committed as rev 126424.
