H.J. Lu <hongjiu.lu@intel.com> Mark Kettenis <kettenis@gnu.org> * amd64-tdep.c (amd64_frame_cache): Add saved_sp_reg. (amd64_init_frame_cache): Initialize saved_sp_reg. (amd64_analyze_stack_align): New. (amd64_analyze_prologue): Call it. (amd64_frame_cache): Use saved_sp_reg if it is invalid. Don't set %rip to 8 when halfway aligning the stack. * amd64-tdep.h (amd64_regnum): Add AMD64_R9_REGNUM to AMD64_R14_REGNUM. * i386-tdep.c (i386_frame_cache): Remove stack_align. Add saved_sp_reg. (i386_alloc_frame_cache): Remove stack_align. Initialize saved_sp_reg to -1. (i386_analyze_stack_align): Rewrite. (i386_frame_cache): Use saved_sp_reg if it is valid.
