[Bug target/26146] New: Bootstrapping mainline on Solaris 10/x86 fails

[gcc-bugzilla at gcc dot gnu dot org]

Trying to bootstrap mainline as of 20060206 on i386-pc-solaris2.10 with gas
2.15 and no options to select a specific target fails when trying to build
the amd64 libgcc multilib:

This is due to this patch:

Adding -v to the xgcc invocation above, I see

So an implicit -mtune=i386 is passed, which conflicts with -m64 as observed.

------- Comment #1 from ro at techfak dot uni-bielefeld dot de  2006-02-07 01:10 -------
Fix:
As a workaround, I can configure for i386-sun-solaris2.10; this bootstrap
is currently in stage2 and thus isn't affected.

Jan, this is your patch,  Could you please have a look.  This is a regression
from
the 4.1 branch.

I confirm that I get this same error.  I'm also building on Solaris 10 x86.  My
triple is i386-pc-solaris2.10 as detected by the configuration machinery.  This
is a regression from 4.1 and 4.0 since those bootstrap successfully.

A patch

This patch should fix "configure i386-pc-solaris2.10". But have

# configure i[456]86-pc-solaris2.10
# onfigure --with-cpu=i[3456]86 i386-pc-solaris2.10

ever worked before? My patch doesn't address those.

I can confirm that this patch allows me to bootstrap again.  I'm running the
testsuite now just to check for any regressions, but I don't expect any.

I'm not 100% certain that the configuration machinery is determining the
architecture correctly on Solaris x86 since I am actually running on AMD64
CPU's in 64 bit mode.  However, this didn't cause or fix that problem.

thanks HJ!
