commit 3e5760fcb48528d48deeb60cb885a97bb731160c Author: Joseph Myers Date: Wed Sep 28 20:09:34 2022 +0000 Update _FloatN header support for C++ in GCC 13 GCC 13 adds support for _FloatN and _FloatNx types in C++, so breaking the installed glibc headers that assume such support is not present. GCC mostly works around this with fixincludes, but that doesn't help for building glibc and its tests (glibc doesn't itself contain C++ code, but there's C++ code built for tests). Update glibc's bits/floatn-common.h and bits/floatn.h headers to handle the GCC 13 support directly. In general the changes match those made by fixincludes, though I think the ones in sysdeps/powerpc/bits/floatn.h, where the header tests __LDBL_MANT_DIG__ == 113 or uses #elif, wouldn't match the existing fixincludes patterns. Some places involving special C++ handling in relation to _FloatN support are not changed. There's no need to change the __HAVE_FLOATN_NOT_TYPEDEF definition (also in a form that wouldn't be matched by the fixincludes fixes) because it's only used in relation to macro definitions using features not supported for C++ (__builtin_types_compatible_p and _Generic). And there's no need to change the inline function overloads for issignaling, iszero and iscanonical in C++ because cases where types have the same format but are no longer compatible types are handled automatically by the C++ overload resolution rules. This patch also does not change the overload handling for iseqsig, and there I think changes *are* needed, beyond those in this patch or made by fixincludes. The way that overload is defined, via a template parameter to a structure type, requires overloads whenever the types are incompatible, even if they have the same format. So I think we need to add overloads with GCC 13 for every supported _FloatN and _FloatNx type, rather than just having one for _Float128 when it has a different ABI to long double as at present (but for older GCC, such overloads must not be defined for types that end up defined as typedefs for another type).

This breaks the templated iseqsig implementation for C++ in , when used with types that were previously implemented as aliases. Add the necessary definitions for _Float32, _Float64, _Float128 (when the same format as long double), _Float32x and _Float64x in this case, so that iseqsig can be used with such types in C++ with GCC 13 as it could with previous GCC versions. Also add tests for calling iseqsig in C++ with arguments of such types (more minimal than existing tests, so that they can work with older GCC versions and without relying on any C++ library support for the types or on hardcoding details of their formats). The LDBL_MANT_DIG != 106 conditionals on some tests are because the type-generic comparison macros have undefined behavior when neither argument has a type whose set of values is a subset of those for the type of the other argument, which applies when one argument is IBM long double and the other is an IEEE format wider than binary64.
