unrecognizable insn on HPUX 10.20


Hello.

I guess this should be reported to you. It happens, when compiling
ImageMagick-4.0.3 on HPUX-10.20.

--------------------8<----------------------------------
~/ftps/ImageMagick-4.0.3 #gcc --verbose --version
egcs-2.91.15 980321 (gcc-2.8.0 release)
~/ftps/ImageMagick-4.0.3 #make
Making all in magick

-O3 and -O2 gives same result...

Egcs was configured with:
../configure --prefix=/opt/local --with-local-prefix=/opt/local --enable-shared --enable-haifa --with-gnu-as
and compiled with *FLAGS='-O3 -s' without errors, or patching.

Image Magick was configured with:
export CFLAGS='-O3 -s'
./configure  --prefix=/opt/local/X11 --enable-shared --enable-lzw --enable-16bit-pixel
