* mips-tdep.c (mips16_scan_prologue): Replace read_next_frame_reg
by frame_unwind_register_signed calls.
(mips32_scan_prologue): Likewise. Skip analysis of alloca stack
frame allocations when called with NULL NEXT_FRAME parameter.
(read_next_frame_reg): Remove.
* sh-tdep.c (sh_analyze_prologue): Add FPSCR parameter. Use it
instead of reading the FPSCR register.
(sh_frame_cache): Pass unwound FPSCR register value to
sh_analyze_prologue.
(sh_skip_prologue): Pass dummy FPSCR value to sh_analyze_prologue.
* v850-tdep.c (v850_analyze_prologue): Add CTBP parameter. Use it
instead of reading the CTBP register.
(v850_frame_cache): Pass unwound CTBP register value to
v850_analyze_prologue.
