Add support for single register window model on SPARC
2011-06-27 Eric Botcazou <ebotcazou@adacore.com>
* sparc-tdep.h (struct sparc_frame_cache): Add frame_offset,
saved_regs_mask and copied_regs_mask fields.
(sparc_record_save_insn): New prototype.
* sparc-tdep.c (sparc_alloc_frame_cache): Initialize the new fields.
(sparc_record_save_insn): New function.
(sparc_analyze_prologue): Add head comment. Recognize store insns
of call-saved registers. Use OFFSET consistently. Recognize flat
frames and cache their settings.
(sparc32_skip_prologue): Handle flat frames.
(sparc_frame_cache): Add frame_offset to the base address.
(sparc32_frame_cache): Adjust to new frame description.
(sparc32_frame_prev_register): Likewise.
* sparc64-tdep.c (sparc64_frame_prev_register): Likewise.
* sparc-sol2-tdep.c (sparc32_sol2_sigtramp_frame_cache): Likewise.
* sparc64-sol2-tdep.c (sparc64_sol2_sigtramp_frame_cache): Likewise.
* sparcnbsd-tdep.c (sparc32nbsd_sigcontext_frame_cache): Force the
frame by calling sparc_record_save_insn.
* sparc64nbsd-tdep.c (sparc64nbsd_sigcontext_frame_cache): Likewise.
* sparcobsd-tdep.c (sparc32obsd_sigtramp_frame_cache): Likewise.
* sparc64obsd-tdep.c (sparc64obsd_frame_cache): Likewise.
