This series of patches fix PR61441. This patch makes resulting NaN values
to be quiet NaN for real value operations, irrespective of the flag_signaling_nans
flag. The caller has the responsibility to avoid the operation if flag_signaling_nans
is on.
gcc/
* real.c (do_add): Make resulting NaN value to be qNaN.
(do_multiply, do_divide, do_fix_trunc): Same.
(real_arithmetic, real_ldexp, real_convert): Same.
(real_isinteger): Updated comment stating it returns false for sNaN.

* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Record_Type>: During
layout in type_annotate_only mode, skip discriminants of derived
tagged types renaming those of the parent type.
In type_annotate_only mode, if the type is tagged, do not override a
size clause but take into account the alignment of the tag.
(annotate_rep): In type_annotate_only mode, deal with discriminants
of derived tagged types renaming those of the parent type.
From-SVN: r231860
* gcc-interface/utils.c (maybe_pad_type): In type_annotate_only mode,
retrieve the component type if this is an array and do not issue the
warning for concurrent types.

This series of patches fix PR61441. This patch removes flag_errno_math check
for RINT, treating it similar to nearbyint.
Bootstrapped & regression-tested on x86_64-linux-gnu.

* match.pd (f(x) -> x): Removed flag_errno_math check for RINT.

This series of patches are for fixing PR61441. This patch modifies code to use
REAL_VALUE_ISSIGNALING_NAN instead of REAL_VALUE_ISNAN to avoid the operatins
only for sNaN operands.
Bootstrapped & regression-tested on x86_64-linux-gnu.
gcc/
* fold-const.c (const_binop): Use REAL_VALUE_ISSIGNALING_NAN instead
of REAL_VALUE_ISNAN to avoid the operation for sNaN operands.
* simplify-rtx.c (simplify_const_binary_operation): Same.
