Fri Apr 28 16:22:34 2000 Andrew Cagney <cagney@b1.cygnus.com>
* blockframe.c (frameless_look_for_prologue): Use
PROLOG_FRAMELESS_P instead of SKIP_PROLOGUE_FRAMELESS_P.
* gdbarch.sh (PROLOG_FRAMELESS_P): Define.
* gdbarch.h, gdbarch.c: Re-generate.
* arch-utils.h, arch-utils.c (generic_prologue_frameless_p): New
function.
