From 8dccd430c9de0e6cf747ae4bb1bf9d944fe3397c Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Fri, 18 Mar 2011 18:42:41 +0000 Subject: gdb/ * dwarf2loc.c (read_pieced_value): Handle get_frame_register_bytes returning that the register piece is unavailable/optimized out. (write_pieced_value): Handle get_frame_register_bytes returning that the register piece is unavailable/optimized out when doing a read-modify write of a bitfield. * findvar.c (value_from_register): Handle get_frame_register_bytes returning that the register piece is unavailable/optimized out. * frame.c (get_frame_register_bytes): New parameters `optimizedp' and `unavailablep'. Throw error on bad debug info. Use frame_register instead of frame_register_read, to fill in the new arguments. * frame.h (get_frame_register_bytes): New parameters `optimizedp' and `unavailablep'. * valops.c: (value_assign): Adjust, and handle get_frame_register_bytes failing. * spu-tdep.c: Include exceptions.h. (spu_software_single_step): Adjust, and handle get_frame_register_bytes failing. (spu_get_longjmp_target): Ditto. * gdbarch.sh (register_to_value): Change to return int. New parameters `optimizedp' and `unavailablep'. * gdbarch.h, gdbarch.c: Regenerate. * i386-tdep.c (i386_register_to_value): Adjust to new gdbarch_register_to_value interface. * i387-tdep.c (i387_register_to_value): Ditto. * i387-tdep.h (i387_register_to_value): Ditto. * alpha-tdep.c (alpha_register_to_value): Ditto. * ia64-tdep.c (ia64_register_to_value): Ditto. * m68k-tdep.c (m68k_register_to_value): Ditto. * mips-tdep.c (mips_register_to_value): Ditto. * rs6000-tdep.c (rs6000_register_to_value): Ditto. --- gdb/m68k-tdep.c | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) (limited to 'gdb/m68k-tdep.c') diff --git a/gdb/m68k-tdep.c b/gdb/m68k-tdep.c index 082cb84..2706969 100644 --- a/gdb/m68k-tdep.c +++ b/gdb/m68k-tdep.c @@ -203,9 +203,10 @@ m68k_convert_register_p (struct gdbarch *gdbarch, /* Read a value of type TYPE from register REGNUM in frame FRAME, and return its contents in TO. */ -static void +static int m68k_register_to_value (struct frame_info *frame, int regnum, - struct type *type, gdb_byte *to) + struct type *type, gdb_byte *to, + int *optimizedp, int *unavailablep) { gdb_byte from[M68K_MAX_REGISTER_SIZE]; struct type *fpreg_type = register_type (get_frame_arch (frame), @@ -216,12 +217,20 @@ m68k_register_to_value (struct frame_info *frame, int regnum, { warning (_("Cannot convert floating-point register value " "to non-floating-point type.")); - return; + *optimizedp = *unavailablep = 0; + return 0; } /* Convert to TYPE. */ - get_frame_register (frame, regnum, from); + + /* Convert to TYPE. */ + if (!get_frame_register_bytes (frame, regnum, 0, TYPE_LENGTH (type), + from, optimizedp, unavailablep)) + return 0; + convert_typed_floating (from, fpreg_type, to, type); + *optimizedp = *unavailablep = 0; + return 1; } /* Write the contents FROM of a value of type TYPE into register -- cgit v1.1
