Hopefully all interested parties are addressed in the cc lists.

The launcher ergonomics (ergo.c) currently relies on per-architecture,
eg ergo_sparc.c, ergo_i586.c, files to define the actual ergonomics
operations. Only x86 is actually CPU specific, both sparc and zero share
the same platform independent implementation. It will simplify things if
we provide a platform independent default in ergo.c that is
conditionally compiled, and modify the build system to cause that
compilation if a platform specific ergo file is not found.
We can potentially delete all the ergo_*.c files except for ergo_i586.c,
and we no longer require that there be a per-architecture file, which
makes additional porting easier.
Gary: do you mind seeing ergo_zero.c go away, or would you prefer to
leave it in case someone is doing a local customization? I suppose the
some consideration could be given to ergo_sparc.c too. Is anybody aware
of downstream distros that modify these files to change the default
ergonomics policies?
Thanks,
David Holmes
