[Bug bootstrap/30726] New: bootstrap support for x86_64-*-solaris2.10

[pdb_ml at yahoo dot com dot au]

Request: Add x86_64-*-solaris2.10 support to the bootstrap process.

Additional Info:
While i386-*-solaris2.10 builds a compiler capable of build x86_64/amd64 object
files with the -m64 command line option, it was not possible (for me) to build
a compiler that default to 64-bit code generation for this platform. 

Support for this is available on Solaris/SPARC with sparc-sun-solaris2* vs
sparc64-sun-solaris2*, and all the hard work has been done (in that code
generation works) but I was unable to find the correct of flags to change in
gcc/config.gcc and gcc/config/i386/* to make 64-bit the default compilation
mode of the generated compiler.

I have been working at this myself for two days now and always seem to run into
problems, with either the generated compiler reverting to generating 32-bit
code, the assembler rejecting the generated code (various reasons, probably
related to incorrect flags being passed to 'as'), or 98% files generated in
64-bit mode and one or two being generated in 32-bit causing link errors.

To-date I have made new target in gcc/config.gcc for x86_64-*-solaris2.10 based
on the existing i*86-*-solaris2* code and tried modifying
gcc/config/i386-sol10.h to change the default multi-lib. Also I have looked at
TARGET_64BIT and tried setting TARGET_64BIT_DEFAULT by hacking the biarch.?
file.

Suggestions / Pointers / Patches I can could use or test would be greatly
appreciated!

Many thanks in Advance,

PS: Test system - Sun Ultra 40 (AMD Opteron 280) running Solaris 10 11/06,
    using gcc-4.1.2rc1 (20060128) and /usr/sfw/bin/{gcc,gas} and Sun's "ld"

PPS: To Mark and the 4.1.2 release team, I can confirm gcc-4.1.2rc1 builds fine
for sparc-sun-solaris2.10 (with and without --cpu=v9), sparcv9-sun-solaris2.10
and i386-pc-solaris2.10. The SPARC variant had to be built with Sun as/ld as
the recommended combination (several sources) of GNU as (2.17) and Sun ld
results in the DWARF2 debug(-g)/ld align bug is Sun's ld, according to
opensolaris.org snv53 has a fix for this issue, but that is not available as a
patch to Solaris 10 (yet).

A fix is available in the CVS tree of GNU binutils (2.17.x, 2.18).

In bug #34775 I've attached a configuration patch that works for me.

As the originator of this request I can verify that the patch provided by
Fabian Groffen as part of Bug 34775 is functional and works as advertised. I
believe the patch should be reviewed and integrated.

The patch does required his associated patch to binutils-2.18 has documented at
http://sourceware.org/bugzilla/show_bug.cgi?id=5606

Testing Environment: Sun Solaris 10 Update 4 running on Sun Ultra 40 M2, with a
single patch (mentioned above) applied to binutils-2.18 released tar ball.
Bootstrapping compiler was gcc-4.1.2. GCC testsuite not run.
