* dbxread.c (process_one_symbol): When finding an N_FUN symbol
that marks the end of the range of a function, enter a line number
entry that has a line number of zero and a PC offset that matches
the end of the function. This starts a range of PC's for which no
line number information is known.

PC's for which no line number info is found (line number is zero)
then we didn't find any valid line information.

* arm-tdep.c (arm_gdbarch_init): Set fp_model in tdep. Defer setting
up floating-point conversions until we know the floating-point model
in use by the inferior. Don't complain about being unable to
determine the ABI of the inferior when we don't have one.
(arm_extract_return_value): Support different floating-point models.
(arm_store_return_value): Likewise.
* armnbsd-tdep.c (arm_netbsd_aout_init_abi): Set fp_model in tdep to
ARM_FLOAT_SOFT.
(arm_netbsd_elf_init_abi): Set fp_model to ARM_FLOAT_SOFT_VFP.
function.
(arm_netbsd_aout_init_abi): Initialize IN_SOLIB_CALL_TRAMPOLINE.
* config/arm/tm-nbsd.h: Don't include config/tm-nbsd.h, it only
defines one thing and that is incorrect for this port.

* win32-nat.c (display_selector): New function. Displays information
about the information returned by GetThreadSelectorEntry API function.
(display_selectors): New function. Displays the infomation of
the selector given as argument, or of CS, DS ans FS selectors
if no argument is given.
( _initialize_inftarg): Add "w32" as info prefix command.
Add "info w32 selector" as command calling display_selectors.
* ppc-linux-nat.c: Update copyright.
(fetch_register, store_register): Add tid parameter, don't compute
tid here.

parameter. Pass it along to callees.

here, and pass it to calleed functions.
(fill_gregset, supply_fpregset): Clean up formatting.
* gdbarch.c gdbarch.h: Regenerate.

* arm-tdep.h (struct gdbarch_tdep): Add jb_pc and jb_elt_size fields.
* arm-tdep.c (arm_get_longjmp_target): New function.
(arm_gdbarch_init): Initialize jb_pc to -1. If ABI handler changes
this to a positive value register arm_get_longjmp_target as the
longjmp handler.
