John, Jeff,
I suggest to streamline the hppa*-hp-hpux* installation instructions as
follows. Okay?
In fact in the following sections there is even more, and more specific
material, which would be great could you have a look at and help trim.

Subject: [PATCH] install: Streamline the hppa*-hp-hpux* section
gcc:
PR target/69374
* doc/install.texi (Specific) <hppa*-hp-hpux*>: Remove a note on
GCC 4.3.
Remove details on how the HP assembler, which we document as not
working, breaks.

-Specifically, @option{-g} does not work (HP-UX uses a peculiar debugging

There are two default scheduling models for instructions. These are
PROCESSOR_7100LC and PROCESSOR_8000. They are selected from the pa-risc
architecture specified for the target machine when configuring.
