New Revision: 206243

URL: http://gcc.gnu.org/viewcvs?rev=206243&root=gcc&view=rev
Log:
    PR target/59501
    * config/i386/i386.c (ix86_save_reg): Don't return true for drap_reg
    if !crtl->stack_realign_needed.
    (ix86_finalize_stack_realign_flags): If drap_reg isn't live on entry
    and stack_realign_needed will be false, clear drap_reg and need_drap.
    Optimize leaf functions that don't need stack frame even if
    crtl->need_drap.
