There are two variants of this CPU, called 1.0 and 1.1, which have
|
||||
different machine descriptions. You must use the right one for your
|
||||
machine. All 7@var{nn} machines and 8@var{n}7 machines use 1.1, while
|
||||
all other 8@var{nn} machines use 1.0.
|
||||
|
||||
The easiest way to handle this problem is to use @samp{configure
|
||||
hp@var{nnn}} or @samp{configure hp@var{nnn}-hpux}, where @var{nnn} is
|
||||
the model number of the machine. Then @file{configure} will figure out
|
||||
if the machine is a 1.0 or 1.1. Use @samp{uname -a} to find out the
|
||||
model number of your machine.
|
||||
There are several variants of the HP-PA processor which run a variety
|
||||
of operating systems. GNU CC must be configured to use the correct
|
||||
processor type and operating system, or GNU CC will not function correctly.
|
||||
The easiest way to handle this problem is to @emph{not} specify a target
|
||||
when configuring GNU CC, the @file{configure} script will try to automatically
|
||||
determine the right processor type and operating system.
|
||||
|
||||
@samp{-g} does not work on HP-UX, since that system uses a peculiar
|
||||
debugging format which GNU CC does not know about. However, @samp{-g}
|
||||
will work if you also use GAS and GDB in conjunction with GCC. We
|
||||
highly recommend using GAS for all HP-PA configurations.
|
||||
|
||||
You should be using GAS-2.3 (or later) along with GDB-4.12 (or later). These
|
||||
You should be using GAS-2.6 (or later) along with GDB-4.16 (or later). These
|
||||
can be retrieved from all the traditional GNU ftp archive sites.
|
||||
|
||||
Build GAS and install the resulting binary as:
|
||||
GAS will need to be installed into a directory before @code{/bin},
|
||||
@code{/usr/bin}, and @code{/usr/ccs/bin} in your search path. You
|
||||
should install GAS before you build GNU CC.
|
||||
|
||||
@example
|
||||
/usr/local/lib/gcc-lib/@var{configuration}/@var{gccversion}/as
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
where @var{configuration} is the configuration name (perhaps
|
||||
@samp{hp@var{nnn}-hpux}) and @var{gccversion} is the GNU CC version
|
||||
number. Do this @emph{before} starting the build process, otherwise you will
|
||||
get errors from the HPUX assembler while building @file{libgcc2.a}. The
|
||||
command
|
||||
|
||||
@example
|
||||
make install-dir
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
will create the necessary directory hierarchy so you can install GAS before
|
||||
building GCC.
|
||||
|
||||
To enable debugging, configure GNU CC with the @samp{--with-gnu-as} option
|
||||
before building.
|
||||
|
||||
It has been reported that GNU CC produces invalid assembly code for
|
||||
1.1 machines running HP-UX 8.02 when using the HP assembler. Typically
|
||||
the errors look like this:
|
||||
@example
|
||||
as: bug.s @@line#15 [err#1060]
|
||||
Argument 0 or 2 in FARG upper
|
||||
- lookahead = ARGW1=FR,RTNVAL=GR
|
||||
as: foo.s @@line#28 [err#1060]
|
||||
Argument 0 or 2 in FARG upper
|
||||
- lookahead = ARGW1=FR
|
||||
@end example
|
||||
|
||||
You can check the version of HP-UX you are running by executing the command
|
||||
@samp{uname -r}. If you are indeed running HP-UX 8.02 on a PA and
|
||||
using the HP assembler then configure GCC with "hp@var{nnn}-hpux8.02".
|
||||
To enable debugging, you must configure GNU CC with the @samp{--with-gnu-as}
|

option before building.
