Bootstrap failures on i386-pc-solaris2.10

Bootstrap failures on i386-pc-solaris2.10

[Art Haas]

Hi.

My builds on my X86 solaris box have failed since yesterday, and
I've just found bug 43615 in Bugzilla which indicates a different
but similar issue for an x86-64 build.I'm running Solaris 10 on an
older Dell box with a Pentium4 chip, and have been building
gcc with the '--disable-multilib' argument for quite some time.

Here's the config info from the last build which worked:

$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/export/home/arth/local/libexec/gcc/i386-pc-solaris2.10/4.5.0/lto-wrapper

Here's the last bits of today's build log - the '--disable-multilib' configure
option should have skipped the 'amd64' stuff below ...

My builds on a sparc-sun-solaris2.10 from yesterday worked fine - on
this machine GCC does _not_ use the '--disable-multilib' configuration
switch. This mornings build has just started.

My thanks to everyone working on GCC.

No, it's not, quite the contrary.  For one, Art did his build before this
patch went in, second, as explained in the message, I've been careful to
only set with_arch_32 and with_tune_32.

The --disable-multilib option has been broken by a recent patch.  This
is a known bug and will hopefully be fixed soon.

Configuring with --with-arch=pentium4 --with-tune=pentium4 is wrong and
doesn't work in the general case, as you've discovered, since it breaks
the 64-bit support.  You just didn't notice the problem before due to
--disable-multilib.  Use --with-arch_32=pentium4 --with-tune_32=pentium4
instead, or simply update to current mainline: my patch to default the
i?86-*-solaris2* configurations to pentium4 just went in.

As for the other configure options: --enable-threads is superfluous,
it's the default.  What are you trying to achieve with
--disable-libstdcxx-pch?

I'll update my repo shortly and replace the '--with-arch' and '--with-tune' arguments as you suggest. As for the '--disable-libstdcxx-pch'
argument, I had build problems months ago and this argument fixed the problem, although now looking at the configure script for libstdc
it looks like the correct argument should be '--enable-libstdcxx-pch=no' if it is to be used. The '--enable-threads' argument is another configuration option I added long ago as well. The script which configures and starts my GCC builds needs some cleanup ...

Thanks.

No, --enable-<feature>=no and --disable-<feature> should be equivalent
everywhere, even if only one form is documented.

True: one you have something that works, you seldom revisit it ;-)

RE: Bootstrap failures on i386-pc-solaris2.10

[Arthur Haas]

By updating to the lastest code in the trunk, and removing the '--with-arch' and '--with-tune' options from my configuration, I've successfully built the latest GCC code. I'll be removing the '--disable-multilib' option from my build configuration now also.

Thanks.

Should be fixed now with r157916 which reverts the offending commit.
Apologies for the breakage.
