7 years agoRestore DECIMAL_DIG macro to C99/C11 value.
Joseph Myers [Fri, 17 Feb 2017 23:04:14 +0000 (23:04 +0000)]
Restore DECIMAL_DIG macro to C99/C11 value.

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.

7 years agors6000: Fix extendsfdf2 for signaling NaNs

rs6000: Fix extendsfdf2 for signaling NaNs

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.

an frsp or similar insn.
