+Status: submitted similar patch 2004-12-08
+
+This patch cleans up the initialization of thread_db.  It works for static
+binaries now.  The vsyscall patches hide this problem, since new static
+binaries will load the vsyscall DSO and then trigger thread_db; but
+this is still a good cleanup.

+Status: Unsuitable for upstream (at least, without a lot of arguing).
+
+GCC does not specify the state of every last register in the CIE.  Since
+GCC's focus is on correctness of runtime unwinding, any registers which
+have to be unwound will be specified; but unmodified registers will not
+be explicitly marked.  (How about modified, call-clobbered registers?
+I'm not sure if they are marked as unavailable.)
+
+GDB issues a noisy warning about this.  The warning is generally not useful,
+and we can get it extremely frequently (any time we load a new CIE).
+
+This patch disables the warning.  Alternately we could set the complaints
+threshold to zero, or implement a default frame init-register method for
+every architecture.  But someday the compiler will support using different
+calling conventions for internal functions, so that's not much of a stopgap. 
+ARM has a complex algorithm for handling this, involving scanning all CIEs -
+benefit not completely clear outside of the ARM context of flexible register
+sets.
