Re: RFA: initialize per-arch data in startup_gdbarch

[Jim Blandy <jimb@zwingli.cygnus.com>]

Here's the (much simpler) patch that works the way you want, I think.

2001-06-06  Jim Blandy  <jimb@redhat.com>

	* gdbarch.sh: Changes to effect the following:
	* gdbarch.c (initialize_non_multiarch): New function.
	* gdbarch.h (initialize_non_multiarch): New declaration.
	* arch-utils.c (initialize_current_architecture): For
	non-multiarch configurations, call initialize_non_multiarch.
