  Committed this version with some adjustments as compared to V1.  Both the
changes summarised below are minor in nature.

[Summary of changes in V2]
  - Move the removal of common-empty-4.s test earlier to the patch "gas:
  sframe: add support for .cfi_negate_ra_state" instead of "gas: sframe:
  testsuite: add testcase for .cfi_negate_ra_state".
  - [readelf/objdump] Use marker "[s]" to also designate when return address in
  register is mangled. In V1, we were doing so only for the case when return
  address is saved on stack.
[End of changes in V2]

Thanks,
Indu Bhagat (6):
  sframe.h: add support for .cfi_negate_ra_state
  gas: sframe: add support for .cfi_negate_ra_state
  libsframe: provide new access API for mangled RA bit
  objdump/readelf: sframe: emit marker for FREs with mangled RA
  gas: sframe: testsuite: add testcase for .cfi_negate_ra_state
  sframe: doc: update spec for the mangled-RA bit in FRE
