Hello,
gcc 3.1 is quite old. Can you reproduce this error on a newer version
(ie 3.2.3)? Thanks,
Dara

+===========================GNAT BUG DETECTED==============================+
| 3.1 (20020212) (i686-pc-linux-gnu) GCC error: |
| RTL flag check: REG_POINTER used with unexpected rtx code `mem' in |

I have try it without -march=athlon and/or a gcc build with default setup -- same problem when I tries to bootstrap with -O3
Why is it saying 3.1 (20020212)?
The problem have be there for more that a week!
>How-To-Repeat:
build gcc from CVS (20020513)
../gcc/configure --enable-languages='c,ada,c++,f77,java,objc' --enable-threads=posix --enable-long-long --disable-nls
(time make bootstrap) && (cd gcc/;time make gnatlib_and_tools)
or
(time make CFLAGS='-march=athlon -pipe -O2' STAGE1_CFLAGS='-march=athlon -pipe -O2' BOOT_CFLAGS='-march=athlon -pipe -O2' bootstrap ) && (cd gcc/;time make CFLAGS='-march=athlon -pipe -O2' STAGE1_CFLAGS='-march=athlon -pipe -O2' GNATLIBCFLAGS='-march=athlon -pipe -O2' BOOT_CFLAGS='-march=athlon -pipe -O2' gnatlib_and_tools)
and rebuild it with -O3
../gcc/configure --enable-languages='c,ada,c++,f77,java,objc' --enable-threads=posix --enable-long-long --disable-nls --prefix=/home/lasj/Test1
(time make CFLAGS='-V -O3' STAGE1_CFLAGS='-O3' BOOT_CFLAGS='-O3' bootstrap ) && (cd gcc/;time make CFLAGS='-O3' STAGE1_CFLAGS='-O3' GNATLIBCFLAGS='-O3' BOOT_CFLAGS='-O3' gnatlib_and_tools)
or
