2017-02-17Restore DECIMAL_DIG macro to C99/C11 value.Joseph Myers11-32/+27
By extending the set of floating types, TS 18661-3 thereby affected the definition of DECIMAL_DIG, which is defined in terms of the "widest supported floating type". This is not conditional on whether __STDC_WANT_IEC_60559_TYPES_EXT__ is defined when <float.h> is included. I raised this possible incompatibility with C11 (an implementation should be able to conform simultaneously with C11, and with C11 + TS 18661) in DR#501. This is not yet resolved, but the latest proposal <http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2108.pdf> would obsolete DECIMAL_DIG with the intention of limiting it to the C11 types (so making it equivalent to LDBL_DECIMAL_DIG). (This proposal is intended to go along with a corresponding change to TS 18661-3 to avoid the new types and non-arithmetic interchange encodings affecting the value of DECIMAL_DIG.) To avoid releasing GCC 7 with a wider-than-C11 value of DECIMAL_DIG and possibly reverting back to a C11 value in a future release, this patch reverts back to the C11 value now. If the proposed resolution to DR#501 changes again so that DECIMAL_DIG *should* have a wider-than-C11 value, we can move back to a wider-than-C11 value in GCC 8. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc/c-family: * c-cppbuiltin.c (builtin_define_float_constants): Define __DECIMAL_DIG__ to the value for long double. gcc/testsuite: * gcc.dg/c11-float-2.c: New test. * gcc.dg/torture/float128-floath.c, gcc.dg/torture/float128x-floath.c, gcc.dg/torture/float16-floath.c, gcc.dg/torture/float32-floath.c, gcc.dg/torture/float32x-floath.c, gcc.dg/torture/float64-floath.c, gcc.dg/torture/float64x-floath.c: Do not test comparison of *_DECIMAL_DIG macros with DECIMAL_DIG.

2017-02-17rs6000: Fix extendsfdf2 for signaling NaNsSegher Boessenkool2-4/+26
A cast from float to double should turn a signaling NaN into a quiet NaN, if using -fsignaling-nans. On PowerPC single-precision floats are stored as double precision in registers, and so, the cast normally does nothing. This causes gcc.dg/pr59833.c to fail (it does such a cast, and expects a quiet NaN as output). This patch adds a new pattern, used with -fsignaling-nans in effect, that creates an frsp instruction (or xsrsp) in this case. Since the input already is SFmode, that instruction turns signaling NaNs into quiet NaNs and does nothing more. * config/rs6000/rs6000.md (extendsfdf2): Remove default arguments. If HONOR_SNANS (SFmode) force the input to a register. (*extendsfdf2_fpr): Add !HONOR_SNANS (SFmode) condition.
