There has long been some clamoring for a amd64-*-solaris2 configuration
similar to sparcv9-sun-solaris2. I've resisted this for quite some
time, primarily because it doubles the maintenance effort of testing
both the 32-bit default and 64-bit default configurations.
After the recent cleanup patches to the Solaris configuration, it proved
to be quite easy and straight forward to implement. Only a few changes
are worth mentioning:
* TRY_EMPTY_VM_SPACE for amd64 had to be massively reduced in
host-solaris2.c, otherwise mmap would fail with ENOMEM. The old value
had been in the middle of the 64-bit address space, which obviously
doesn't work.
* The TARGET_LD_EMULATION macro needed a clause to properly deal with
the default case: at first, I had used a 32-bit GNU ld for the 64-bit
configuation, which only works if you explicitly specify the 64-bit
emulation. I'm leaving this in although a 32-bit gld doesn't work
properly: the lto-plugin is built as 64-bit object, thus all -flto
tests fail in such a configuration.
I think practically the whole patch falls under the Solaris
maintainership, with the possible exception of the change to the copy of
libtool.m4 in libgo/config. This is not for the technical content, but
for the special commit rules to that directory. Ian?
Anyway, this part of the patch will have to go to upstream libtool.
Ralf, could you take care of that?
Bootstrapped without regression on i386-pc-solaris2.10 (both 32-bit
default and 64-bit default configurations), i386-pc-solaris2.11 and
sparc-sun-solaris2.11 in progress.
There are two caveats, which will be addressed subsequently:
* libstdc++-abi/abi_check FAILs for the 64-bit ABI due to a mismatch
between --print-multi-directory and --print-multi-os-directory. I'll
report and hopefully address this subsequently; the problem already
exists in the the existing sparcv9-sun-solaris2 configurations.
* In the sparcv9-sun-solaris2.11 builds, the 32-bit libgo tests fail to
link since they have unresolved references to
__sync_bool_compare_and_swap_8 and __sync_add_and_fetch_8. I could
trace this to -mv8plus being missing in that configuration. I'm
uncertain where best to handle this. Eric?
Once all the bootstraps have finished, I'll commit this patch (at least
the non-libgo parts) unless anything unexpected comes up.
