- Subject: Remove obsolete Solaris 10 support
With the GCC 9.1 release out of the door, this patch implements the
removal of Solaris 10 support that had been obsoleted in GCC 9.
The patch is mostly straightforward:
* removing Solaris 10-only code and documentation,
* simplifying configure triplets, using *-*-solaris2* everywhere since
this effectively means *-*-solaris2.11* now, and
* simplifying the v3 Solaris baselines and configuration since there's
now only a single one left. (Just FTR, I've omitted the baseline
renames and removals from the patch below to avoid blowing it up to
insane sizes.)
Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11 and tested on i386-pc-solaris2.10 to make sure the
configuration is properly rejected.
I've also inspected the resulting gccinstall.info and gccinstall.pdf.
The vast majority of the patch falls squarely under my Solaris
maintainership. I'm uncertain about the libbacktrace/configure.ac bit
and will submit the libgo part separately.
There are primarily two areas left with Solaris 10 references in them:
* fixincludes/inclhack.def: I'll have to check in great detail which of
the fixes apply to Solaris 10 only and can thus be removed.
* libgcc/config/sparc/sol2-unwind.h: Again, it's difficult to tell which
cases only applied to Solaris 10 and can go.
I'll give maintainers a day or two to comment before committing.
