......@@ -304,3 +304,14 @@ Why: The support code for the old firmware hurts code readability/maintainabilit
and slightly hurts runtime performance. Bugfixes for the old firmware
are not provided by Broadcom anymore.
Who: Michael Buesch <mb@bu3sch.de>
---------------------------
What: Solaris/SunOS syscall and binary support on Sparc
When: 2.6.26
Why: Largely unmaintained and almost entirely unused. File system
layering used to divert library and dynamic linker searches to
/usr/gnemul is extremely buggy and unfixable. Making it work
is largely pointless as without a lot of work only the most
trivial of Solaris binaries can work with the emulation code.
