A not so stellar result on Solaris 10

A not so stellar result on Solaris 10

[Dennis Clarke]

Gentlemen : 

    So after a pile of noises made I was ableto finally posts ome sort of result : 

        http://gcc.gnu.org/ml/gcc-testresults/2012-11/msg01367.html

    Not exactly what I was hoping for but it seems to be a step in the right direction. Notice
that I gave up on the --disable-multilib option and did embrace the --disable-nls which allowed
stage 1 to complete. 

Not too sure what to make of all those failures with g++ or gcc for that matter. 
Everything else was flawless. 

My builds on old old Solaris 8 are still going .. no end in sight yet.

I think that the visibility failures are expected - because of the antiquated 
assembler.  You need to use the GNU assembler if you want to have all the 
fancy C++ features, as well as other advanced features.

The gnat.dg/lto14.adb failure is also expected (it's adjusted on the branch).

The g++.dg/cpp0x/nullptr28.C and libgomp.c/sort-1.c failures aren't expected.

Mostly I want a clean GCC compiler. So therefore I see binutils-2.23.1 was just
released last week. Perhaps I will give that a build ( with this GCC ) and then
ensure it has the "g" prefix and try a re-bootstrap of GCC again with gas as the
assembler. This may provide the cleaner results I am looking for.

I guess that is fixed in 4.7.3 then .. no worries there. Maybe there is a simply patch
that can be applied at this time ? 

> The g++.dg/cpp0x/nullptr28.C and libgomp.c/sort-1.c failures aren't expected.

I have no idea where they are coming from however, no worries, could be a symptom
of not using gas and/or some other non-obvious factor in the GNU stack I have.  The plan
at some point is to have a single GNU stack in /usr/local which is 64-bit everywhere 
but with a GCC compiler in /usr/local/gcc4 that is happy to handle either 32-bit or 
64-bit tasks. 

Something I did notice was that the GCC 4.7.2 manual still refers to a -mcpu option of v7 
and also v8 as if they would result in different assembler output. Thus far I have tested 
this gcc 4.7.2 with -mcpu=v7 and v8 and checked the output assembly and seen no change. 
I would think v7 has long since been dropped as a supported processor. I don't think I have
seen one in years.  Not even in a junk pile.

The recommended (and tested) binutils version to be used in conjunction with 
GCC 4.7.x is 2.22.x.  That being said, 2.23.1 should work as well.

No, they are still supported, but in 32-bit mode; 64-bit mode forces -mcpu=v9.

gcc 4.7.2 fails to bootstrap in stage 1

I have built gas thus :

Then I tried to bootstap gcc again by using this gcc 4.7.2 and gas and was surprised to see the process fail in stage1 :

Not sure what to make of that. 

I will say that I used my gcc 4.7.2 result to build GNU binutils 2.23.1 with excellent test results and was really surprised to see this fail in stage 1. 
 
> The gnat.dg/lto14.adb failure is also expected (it's adjusted on the branch).

I'll work forwards on this one step at a time and just go with the golden source of 4.7.2 for now. 

> The g++.dg/cpp0x/nullptr28.C and libgomp.c/sort-1.c failures aren't expected.

hrmmm .. another mystery for later.

--with-gnu-as and -with-gnu-ld don't take arguments.  When you need to specify 
assembler or linker, you need to use --with-as=[...] and --with-ld=[...] and, 
in this case, --with-gnu-as and -with-gnu-ld become superfluous since the 
configure script will autodetect.

If GNU as in your PATH, --with-gnu-as is sufficient; otherwise, you need to 
use --with-as=/usr/local/bin/gas (and --with-gnu-as is superfluous).

I suspect that GNU ld is in your PATH and conflicts with --without-gnu-ld, so 
you need to remove it from your PATH or use --with-ld=[...].

ah ha .. well I want to use the Sun provided linker as there were long standing problems with GNU ld in the Solaris world. Not sure if I can dig up the bugs but /usr/ccs/bin/ld is supposed to work perfectly. The assembler however is another matter and I will try your changes.
