This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
uninterpreted formats. If fmt is one of the uninterpreted types
don't update the FPR_STATE. Handle fmt_uninterpreted_32 like
fmt_word, and fmt_uninterpreted_64 like fmt_long.
(store_fpr): When writing an invalid odd register, set the
matching even register to fmt_unknown, not the following register.
* interp.c (sim_open): If STATE_MEM_SIZE isn't set then set it to
the the memory window at offset 0 set by --memory-size command
line option.
(sim_store_register): Handle storing 4 bytes to an 8 byte floating
point register.
(sim_fetch_register): Likewise for reading 4 bytes from an 8 byte
register.
(sim_monitor): When returning the memory size to the MIPS
application, use the value in STATE_MEM_SIZE, not an arbitrary
hardcoded value.
(cop_lw): Don' mess around with FPR_STATE, just pass
fmt_uninterpreted_32 to StoreFPR.
(cop_sw): Similarly.
(cop_ld): Pass fmt_uninterpreted_64 not fmt_uninterpreted.
(cop_sd): Similarly.
* mips.igen (not_word_value): Single version for mips32, mips64
and mips16.

instructions.

(value_fpr, store_fpr, fp_cmp, fp_unary, fp_binary, fp_mac)
(fp_inv_sqrt, fpu_format_name): Add paired-single support.
(convert): Note that this function is not used for paired-single
format conversions.

(check_fmt_p): Enable paired-single support.
(ALNV.PS, CVT.PS.S, CVT.S.PL, CVT.S.PU, PLL.PS, PLU.PS, PUL.PS)
(PUU.PS): New instructions.
(CVT.S.fmt): Don't use this instruction for paired-single format
destinations.
* sim-main.h (FP_formats): New value 'fmt_ps.'
(ps_lower, ps_upper, pack_ps, convert_ps): New prototypes.

* cp1.c: Fix more comment spelling and formatting.
(value_fcr, store_fcr): Use fenr_FS rather than hard-coding value.
(denorm_mode): New function.
(fpu_unary, fpu_binary): Round results after operation, collect
status from rounding operations, and update the FCSR.
(convert): Collect status from integer conversions and rounding
operations, and update the FCSR. Adjust NaN values that result
from conversions. Convert to use sim_io_eprintf rather than
fprintf, and remove some debugging code.
* cp1.h (fenr_FS): New define.
* sim-main.h (Nan, Infinity, Less, Equal, AbsoluteValue, Negate)
(Add, Sub, Multiply, Divide, Recip, SquareRoot): Move lower in
file, remove PARAMS from prototypes.
(value_fpr, store_fpr, convert): Likewise. Use SIM_STATE to provide
simulator state arguments.
(ValueFPR, StoreFPR, Convert): Move lower in file. Use SIM_ARGS to
pass simulator state arguments.
