[lno] bootstrap broken

[Volker Reichelt <reichelt at igpm dot rwth-aachen dot de>]

Hi,

Dorit's port of the tree-vectorizer patch to the lno-branch
http://gcc.gnu.org/ml/gcc-cvs/2004-08/msg01190.html
breaks bootstrap of the lno-branch on i686-pc-linux-gnu. I get

  stage1/xgcc -Bstage1/ -B/home/reichelt/GCC/FARM/gcc-lno-20040824/i686-pc-linux-gnu/bin/ -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Werror -fno-common   -DHAVE_CONFIG_H    -I. -I. -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/../include -I../../gcc/gcc/../libcpp/include -I../../gcc/gcc/../libbanshee/libcompat -I../../gcc/gcc/../libbanshee -I../../gcc/gcc/../libbanshee/points-to  ../../gcc/gcc/tree-vectorizer.c -o tree-vectorizer.o
  ../../gcc/gcc/tree-vectorizer.c: In function `vect_can_force_dr_alignment_p':
  ../../gcc/gcc/tree-vectorizer.c:1443: warning: comparison between signed and unsigned
  make[2]: *** [tree-vectorizer.o] Error 1

The code in question is:

  static bool 
  vect_can_force_dr_alignment_p (tree decl, unsigned int alignment)
  { 
    if (TREE_CODE (decl) != VAR_DECL)
      return false;

    if (DECL_EXTERNAL (decl))
      return false;

    if (TREE_STATIC (decl))
      return (alignment <= MAX_OFILE_ALIGNMENT);
    else
      /* This is not 100% correct.  The absolute correct stack alignment
         is STACK_BOUNDARY.  We're supposed to hope, but not assume, that
         PREFERRED_STACK_BOUNDARY is honored by all translation units.
         However, until someone implements forced stack alignment, SSE
         isn't really usable without this.  */   
      return (alignment <= PREFERRED_STACK_BOUNDARY);  /* <--- line 1443 */
  }

It's wierd that my mainline bootstrap isn't affected.
Any ideas?

Thanks,
Volker
