      PR c/70085 reported a false-positive from -Wmisleading-indentation.

The warning was fixed by the fix for PR c/68187 (r233972), but it seems
worth capturing the reproducer for PR c/70085 as an additional test case,
as it's slightly different to those seen in PR c/68187.

    • S/390: Fix rounding for _Decimal128 to _Decimal32 conversion · 432d4670 
      We do not have a direct conversion instruction from 128 bit DFP to 32
bit DFP so this needs to be done in two steps.  The first needs to be
done with the "prepare for shorter precision rounding mode" in order
to produce a correct result.

gcc/ChangeLog:

2016-03-11  Andreas Krebbel  <krebbel@linux.vnet.ibm.com>

	* config/s390/s390.md ("trunctddd2"): Turn former define_insn into
	define_expand.

    • S/390: Define macros for rounding mode constants · ae8e301e 
      This patch replaces a few magic numbers used for floating point
rounding modes with macros.  This is mostly a NoOp change apart from:

fixuns_truncdddi2, fixuns_trunctddi2, fixuns_trunc<mode>si2: Replace 5
with DFP_RND_TOWARD_0 (which is 9).

5 as well as 9 represent round towards 0 with the difference that for
5 the new DFP quantum exception is enabled as well.  This exception
isn't IEEE754 and we do not have an interface to enable and test it
anyway.  So we do not intend to enable it.  This so far should not
have any noticable effect since the quantum exception was not
observable through the Posix functions.

Some pattern ("fix_trunc<mode>di2") is already using rounding mode 9
correctly.

gcc/ChangeLog:

2016-03-11  Andreas Krebbel  <krebbel@linux.vnet.ibm.com>

	* config/s390/s390.md (BFP_RND_*, DFP_RND_*): Add new constant
	definitions for BFP and DFP rounding modes.

	("fixuns_trunc<BFP:mode><GPR:mode>2", "fixuns_trunc<mode>si2")
	("fix_trunc<DSF:mode><GPR:mode>2", "fix_trunc<mode>di2")
	("fix_trunctf<mode>2"): Use the new constants instead of magic
	numbers.
