Gerhard Tonn) for argument passing on the S/390 and S/390x:
* s390-tdep.c (S390_STACK_FRAME_OVERHEAD): This is always space
for 16 registers, and then 32 more bytes.
(S390_STACK_PARAMETER_ALIGNMENT, S390_NUM_FP_PARAMETER_REGISTERS):
New macros.
(is_double_arg): The s390x doesn't handle DOUBLE_ARGS specially.
Move up in the file, since it's now used by is_simple_arg.
(is_simple_arg): Don't assume registers are four bytes long.
Exclude all double arguments. Extended floats are not simple
args.
(is_power_of_two): New function.
(pass_by_copy_ref): Call is_power_of_two, and check that the
length fits in a register, rather than listing all the acceptable
sizes. Extended floats are not passed by reference.
(s390_push_arguments): Don't assume registers are four bytes long.
Reserve an argument register to point to the buffer for structures
returned by value. Use S390_NUM_FP_PARAMETER_REGISTERS and
S390_STACK_FRAME_OVERHEAD.
* remote.c (remote_write_bytes): Explicitly compute and then use
the payload size. Update comments to reflect. Fixes problem of
GDB not sending small packets as found by Fred Fish.
(res_null_text): New static const struct res_id object,
with empty unicode name field.
(control): Pop parsing of optresidc up one level. Set
res_text_field to $2 except for controls which do not accept
a text field. Set res_text_field to res_null_text for the
special cases (viz. COMBOBOX, EDITTEXT, LISTBOX, SCROLLBAR).
(control_params): Adjust to use res_text_field rather
than optresidc.
(COMBOBOX): Add comment about discrepency between documented
vs. observed default style.
* resrc.c (define_control): Make first param const.
* windres.h (define_control): Adjust prototype.

* m68hc11-tdep.c (m68hc11_call_dummy_address): Delete function.

(avr_gdbarch_init): Do not set call_dummy_address.
* symfile.c (syms_from_objfile): Move variables to inner block.
Move the checks for the non-mainline case a bit earlier to avoid
doing some useless computations.
