(rs6000_in_function_epilogue_p): Use extract_unsigned_integer. (refine_prologue_limit): Delete. (skip_prologue): Don't call it. Use extract_unsigned_integer. Assume lim_pc is set. Correct check for incomplete prologues. Do not skip clobbers of the frame pointer. * symtab.c (skip_prologue_using_sal): Fail if there is only one sal. * gdb.arch/powerpc-prologue.c (optimized_1_marker, gdb2029_marker) (optimized_1): New. (main): Call optimized_1. (gdb2029): Correct typos. Call gdb2029_marker. * gdb.arch/powerpc-prologue.exp: Run new test. Use a breakpoint for gdb2029.
