Joel Brobecker f749ed6079 Minor comment fixes in sim/common/sim-fpu.c.
This patch makes a fair number of fixes in the various comments of
sim-fpu.c, mostly to either better conform to the GNU Coding Standards
(sentences start with a capital letter, end with a period), or to
fix spelling mistakes.

sim/common/ChangeLog:

        * sim-fpu.c: Minor comment fixes throughout.

Joel Brobecker 8acc9f485b Update years in copyright notice for the 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.

Joel Brobecker 12c3e59c33 Update the copyright header of various files...
... to follow the correct syntax (according to the gospel of
gnulib's update-copyright). In other words:
  - no comma after the last year;
  - FSF spelled exactly "Free Software Foundation, Inc.", with
    the comma and the period at the end.

Mike Frysinger c8551de35c sim: fix fpu missing initializer warnings
The current fpu code with externals enabled results in the warnings:
common/sim-fpu.c:2437: warning: missing initializer
common/sim-fpu.c:2437: warning: (near initialization for 'sim_fpu_zero.sign')
common/sim-fpu.c:2440: warning: missing initializer
common/sim-fpu.c:2440: warning: (near initialization for 'sim_fpu_qnan.sign')

So tweak the old style initializers to avoid these.

Mike Frysinger adaaf009b5 sim: constify sim_fpu_print_status
I've committed the following patch as obvious.  The local "prefix"
variable is only assigned const strings, and only passed to printf()
functions, so add "const" to avoid gcc warnings:
common/sim-fpu.c: In function 'sim_fpu_print_status':
common/sim-fpu.c:2508: warning: initialization discards qualifiers
	from pointer target type
common/sim-fpu.c:2566: warning: assignment discards qualifiers
	from pointer target type

Andrew Cagney 7d93d53871 o CVT.S.W and CVT.W.S were reversed
o When unpacking an r5900 FP value,
  was not treating IEEE-NaN's as very
  large values.
o When packing an r5900 FP result from an infinite
  precision intermediate value was saturating
  to IEEE-MAX instead of r5900-MAX
o The least significant bit of the FP status
  register did not stick to one.
