Hi,

I have a comparison failure when I try to bootstrap the tree-ssa branch:

case "gnucompare" in *compare | *compare-lean ) stage=2 ;; * ) stage=`echo gnucompare | sed -e 's,^[a-z]*compare\([0-9][0-9]*\).*,\1,'` ;; esac; \
if [ -f .bad_compare ]; then \
  echo "Bootstrap comparison failure!"; \
  cat .bad_compare; \
  exit 1; \
else \
  case "gnucompare" in \
    *-lean ) rm -rf stage$stage ;; \
    *) ;; \
  esac; true; \
fi
Bootstrap comparison failure!
intl.o differs
make[1]: *** [gnucompare] Error 1
make[1]: Leaving directory `/home/steven/devel/ssabuild/gcc'
make: *** [bootstrap] Error 2

configured with "--enable-languages=c,c++,objc,f95"
last updated Fri Nov 28 13:39:34 UTC 2003.

Does anyone else see this?

Gr.
Steven

Something in the last 12 hours broke bootstrap with checking enabled for
the tree-ssa branch (last updated 06:22:22 UTC 2003) on i686-pc-linux-gnu:

We lose the tree pointer in tree_simple:get_base_symbol (tree t) when it is
called from set_is_used ().  get_base_symbol() expects a decl, a ref or an ssa
name, but we call it with an INTEGER_CST.

Probably fallout from the "constant propatation into PHIs"-patches??

Folks,

I got a bootstrap failure last night while running SPEC95.
One of these patches introduced this regression.

I haven't looked very hard, but I *think* it might be your patch
Jason.  I had done a bootstrap yesterday that included Andrew's
and Daniel's patch (although that bootstrap didn't include
libjava).  It can't be Daniel's because his change is not in the
tree-ssa path.


Thanks.  Diego.
