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.
