42 Canonical Frame Address (CFA).
275 SFrame header allows specifying explicitly the fixed offsets from CFA, if any,
277 of the return address is @code{CFA - 8}. Since this offset is in close
278 vicinity with the CFA in most ABIs, @code{sfh_cfa_fixed_fp_offset} and
302 @tab The CFA fixed FP offset, if any.
306 @tab The CFA fixed RA offset, if any.
580 The first offset is always used to locate the CFA, by interpreting it as:
581 CFA = @code{BASE_REG} + offset1.
584 interpreting it as: RA = CFA + offset2. If RA is @emph{not} being tracked
586 FP, by interpreting it as: FP = CFA + offset2.
589 the FP, by interpreting it as FP = CFA + offset3.
660 @tab A value of upto 3 is allowed to track all three of CFA, FP and RA.
664 @tab Distinguish between SP or FP based CFA recovery.
