Err, I think there's a misunderstanding here. The src/alloc.c change
is related to sparc64 not Solaris (not _only_ Solaris, that is):
--- a/src/alloc.c Fri Oct 27 15:45:51 2006 +0000
+++ b/src/alloc.c Sat Oct 28 01:49:45 2006 +0300
@@ -4560,7 +4560,11 @@ mark_stack ()
needed on ia64 too. See mach_dep.c, where it also says inline
assembler doesn't work with relevant proprietary compilers.
*/
#ifdef sparc
+#ifdef __sparc64__
+ asm ("flushw");
+#else
asm ("ta 3");
+#endif
#endif
Now, I don't think anybody would argue that there are probably far more
Solaris installations of sparc64 than FreeBSD ones.
If the change is considered too risky for the 23.X release then I can
maintain it as a local FreeBSD patch for 23.X too. We have been running
with this patch in the editors/emacs (based on 22.X) and the CVS-based
editors/emacs-devel port for several months now, so it's not a big
problem to keep it as a local patch in the FreeBSD Ports.
Having said that, if we *do* commit it to the CVS repository, we will
have one less patch to maintain locally. That's usually a good idea :)
