Bootstrap Failure (i686-pc-linux-gnu, --with-arch=pentium4)

[Ranjit Mathew <rmathew at gmail dot com>]

Hi,

  For two consecutive days, I have been unable to
build GCC mainline on i686-pc-linux-gnu:

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I build with "--with-arch=pentium4 --disable-checking" and that
might explain why no one has apparently reported it yet. The
full configure invocation is:
----------------------------------------- 8<
-----------------------------------------
$GCC_SRC_DIR/configure --prefix=$HOME/gcc --enable-languages=c,c++,java \
--with-as=/home/ranmath/gnu/bin/as --with-gnu-as \
--with-ld=/home/ranmath/gnu/bin/ld --with-gnu-ld \
--with-arch=pentium4 --with-tune=pentium4 \
--disable-nls --disable-checking --disable-libmudflap \
--disable-debug --enable-threads=posix --enable-__cxa_atexit
----------------------------------------- 8<
-----------------------------------------

I use FSF GCC 3.4.4 for bootstrapping and FSF binutils
2.16.

Thanks,
Ranjit.
