This patch removes various dead cases from the toplevel configure.ac.
Target ep9312-* isn't known to config.sub at all so those cases have
been dead for a long time; likewise parisc*64*-* (those parisc cases
it does know have also been handled by config.sub as aliases for

This work is independent of the C++ memory model. It is just to prevent the
optimizers from introducing new data races due to code movement. This initial
pass is just to make the optimizations data race safe so that if you have a

They were the dates on sparc.h from which this file was split out. This

While purging Windows code, I failed to remember that VMS has a 32-bit

The attribute enabled feature can help avoid quite a lot of
duplication in the alpha backend. This begins the process
by tackling the easiest -- zero_extension, conditionalized
on the existance of the BWX instruction set extension.
Tested on alpha{,ev5,ev56,ev67}-linux.

We don't get a chance to use attribute enabled here, but we can
eliminate some unnecessary expanders.
The non-BWX expansion paths wound up subregging the input to
DImode to perform the operation and subregging it back. Exactly
as the generic code paths would do.
I didn't investigate what
This handles everything except movdi, which is more complex.
One perhaps non-obvious thing is the use of the ABI as an isa
entry with respect to the loading of an address constant. This
appears in movsi for VMS. This turns out to be significantly
easier than using two different attributes to

We have helper expanders -- originally for the builtins -- so that we can

The predeclared function closed has been removed from the Go language,
as it is no longer necessary now that v, ok = -c returns whether the
channel is closed. This patch implements that in gccgo. This patch
also fixes the handling of case v, ok := -c in a select statement.
