hppa2.0w-hp-hpux11.11 bootstrap comparison failure gcc 11.3.0 and 10.4.0

[Dennis Grevenstein <dennis.grevenstein@gmail.com>]

Hi,

I have tried to build either gcc 10.4.0 or 11.3.0 on hppa2.0w-hp-hpux11.11.
Both produce the same error and fail at the comparison step:

Comparing stages 2 and 3

I am using gcc 9.5.0 to bootstrap:

# gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/hppa2.0w-hp-hpux11.11/9.5.0/lto-wrapper
Target: hppa2.0w-hp-hpux11.11
Configured with: ../gcc-9.5.0/configure --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --disable-nls --with-libiconv-prefix=/usr/local --enable-languages=c,c++,fortran --with-gnu-as --with-as=/usr/local/bin/gas --enable-threads=posix --without-gnu-ld --with-ld=/usr/ccs/bin/ld
Thread model: posix
gcc version 9.5.0 (GCC) 

GNU binutils are 2.21.1. I have also tried updating just GNU as to the
latest 2.38, but that makes no difference.

The configuration command is the same as indicated by gcc-9.5.0.

I would really appreciate any ideas here.

thanks,
Dennis
