-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.
