c++: Implement P1467R9 - Extended floating-point types and standard names compiler part except for bfloat16 [PR106652] The following patch implements the compiler part of C++23 P1467R9 - Extended floating-point types and standard names compiler part by introducing _Float{16,32,64,128} as keywords and builtin types like they are implemented for C already since GCC 7, with DF{16,32,64,128}_ mangling. It also introduces _Float{32,64,128}x for C++ with the https://github.com/itanium-cxx-abi/cxx-abi/pull/147 proposed mangling of DF{32,64,128}x. The patch doesn't add anything for bfloat16_t support, as right now __bf16 type refuses all conversions and arithmetic operations. The patch wants to keep backwards compatibility with how __float128 has been handled in C++ before, both for mangling and behavior in binary operations, overload resolution etc. So, there are some backend changes where for C __float128 and _Float128 are the same type (float128_type_node and float128t_type_node are the same pointer), but for C++ they are distinct types which mangle differently and _Float128 is treated as extended floating-point type while __float128 is treated as non-standard floating point type. The various C++23 changes about how floating-point types are changed are actually implemented as written in the spec only if at least one of the types involved is _Float{16,32,64,128,32x,64x,128x} (_FloatNx are also treated as extended floating-point types) and kept previous behavior otherwise. For float/double/long double the rules are actually written that they behave the same as before. There is some backwards incompatibility at least on x86 regarding _Float16, because that type was already used by that name and with the DF16_ mangling (but only since GCC 12 and I think it isn't that widely used in the wild yet). E.g. config/i386/avx512fp16intrin.h shows the issues, where in C or in GCC 12 in C++ one could pass 0.0f to a builtin taking _Float16 argument, but with the changes that is not possible anymore, one needs to either use 0.0f16 or (_Float16) 0.0f. We have also a problem with glibc headers, where since glibc 2.27 math.h and complex.h aren't compilable with these changes. One gets errors like: In file included from /usr/include/math.h:43, from abc.c:1: /usr/include/bits/floatn.h:86:9: error: multiple types in one declaration 86 | typedef __float128 _Float128; | ^~~~~~~~~~ /usr/include/bits/floatn.h:86:20: error: declaration does not declare anything [-fpermissive] 86 | typedef __float128 _Float128; | ^~~~~~~~~ In file included from /usr/include/bits/floatn.h:119: /usr/include/bits/floatn-common.h:214:9: error: multiple types in one declaration 214 | typedef float _Float32; | ^~~~~ /usr/include/bits/floatn-common.h:214:15: error: declaration does not declare anything [-fpermissive] 214 | typedef float _Float32; | ^~~~~~~~ /usr/include/bits/floatn-common.h:251:9: error: multiple types in one declaration 251 | typedef double _Float64; | ^~~~~~ /usr/include/bits/floatn-common.h:251:16: error: declaration does not declare anything [-fpermissive] 251 | typedef double _Float64; | ^~~~~~~~ This is from snippets like: /* The remaining of this file provides support for older compilers. */ # if __HAVE_FLOAT128 /* The type _Float128 exists only since GCC 7.0. */ # if !__GNUC_PREREQ (7, 0) || defined __cplusplus typedef __float128 _Float128; # endif where it hardcodes that C++ doesn't have _Float{16,32,64,128,32x,64x,128x} support nor {f,F}{16,32,64,128}{,x} literal suffixes nor _Complex _Float{16,32,64,128,32x,64x,128x}. The patch fixincludes this for now and hopefully if this is committed, then glibc can change those. The patch changes those # if !__GNUC_PREREQ (7, 0) || defined __cplusplus conditions to # if !__GNUC_PREREQ (7, 0) || (defined __cplusplus && !__GNUC_PREREQ (13, 0)) Another thing is mangling, as said above, Itanium C++ ABI specifies DF <number> _ as _Float{16,32,64,128} mangling, but GCC was implementing a mangling incompatible with that starting with DF for fixed point types. Fixed point was never supported in C++ though, I believe the reason why the mangling has been added was that due to a bug it would leak into the C++ FE through decltype (0.0r) etc. But that has been shortly after the mangling was added fixed (I think in the same GCC release cycle), so we now reject 0.0r etc. in C++. If we ever need the fixed point mangling, I think it can be readded but better with a different prefix so that it doesn't conflict with the published standard manglings. So, this patch also kills the fixed point mangling and implements the DF <number> _ demangling. The patch predefines __STDCPP_FLOAT{16,32,64,128}_T__ macros when those types are available, but only for C++23, while the underlying types are available in C++98 and later including the {f,F}{16,32,64,128} literal suffixes (but those with a pedwarn for C++20 and earlier). My understanding is that it needs to be predefined by the compiler, on the other side predefining even for older modes when <stdfloat> is a new C++23 header would be weird. One can find out if _Float{16,32,64,128,32x,64x,128x} is supported in C++ by __GNUC__ >= 13 && defined(__FLT{16,32,64,128,32X,64X,128X}_MANT_DIG__) (but that doesn't work well with older G++ 13 snapshots). As for std::bfloat16_t, three targets (aarch64, arm and x86) apparently "support" __bf16 type which has the bfloat16 format, but isn't really usable, e.g. {aarch64,arm,ix86}_invalid_conversion disallow any conversions from or to type with BFmode, {aarch64,arm,ix86}_invalid_unary_op disallows any unary operations on those except for ADDR_EXPR and {aarch64,arm,ix86}_invalid_binary_op disallows any binary operation on those. So, I think we satisfy: "If the implementation supports an extended floating-point type with the properties, as specified by ISO/IEC/IEEE 60559, of radix (b) of 2, storage width in bits (k) of 16, precision in bits (p) of 8, maximum exponent (emax) of 127, and exponent field width in bits (w) of 8, then the typedef-name std::bfloat16_t is defined in the header <stdfloat> and names such a type, the macro __STDCPP_BFLOAT16_T__ is defined, and the floating-point literal suffixes bf16 and BF16 are supported." because we don't really support those right now. 2022-09-27 Jakub Jelinek <jakub@redhat.com> PR c++/106652 PR c++/85518 gcc/ * tree-core.h (enum tree_index): Add TI_FLOAT128T_TYPE enumerator. * tree.h (float128t_type_node): Define. * tree.cc (build_common_tree_nodes): Initialize float128t_type_node. * builtins.def (DEF_FLOATN_BUILTIN): Adjust comment now that _Float<N> is supported in C++ too. * config/i386/i386.cc (ix86_mangle_type): Only mangle as "g" float128t_type_node. * config/i386/i386-builtins.cc (ix86_init_builtin_types): Use float128t_type_node for __float128 instead of float128_type_node and create it if NULL. * config/i386/avx512fp16intrin.h (_mm_setzero_ph, _mm256_setzero_ph, _mm512_setzero_ph, _mm_set_sh, _mm_load_sh): Use 0.0f16 instead of 0.0f. * config/ia64/ia64.cc (ia64_init_builtins): Use float128t_type_node for __float128 instead of float128_type_node and create it if NULL. * config/rs6000/rs6000-c.cc (is_float128_p): Also return true for float128t_type_node if non-NULL. * config/rs6000/rs6000.cc (rs6000_mangle_type): Don't mangle float128_type_node as "u9__ieee128". * config/rs6000/rs6000-builtin.cc (rs6000_init_builtins): Use float128t_type_node for __float128 instead of float128_type_node and create it if NULL. gcc/c-family/ * c-common.cc (c_common_reswords): Change _Float{16,32,64,128} and _Float{32,64,128}x flags from D_CONLY to 0.

C2x follows C++ in making alignas, alignof, bool, false, static_assert, thread_local and true keywords; implement this accordingly. This implementation makes them normal keywords in C2x mode just like any other keyword (C2x leaves open the possibility of implementation using predefined macros instead - thus, there aren't any testcases asserting that they aren't macros). As in C++ and previous versions of C, true and false are handled like signed 1 and 0 in #if (there was an intermediate state in some C2x drafts where they had different macro expansions that were unsigned in #if). Bootstrapped with no regressions for x86_64-pc-linux-gnu. As with the removal of unprototyped functions, this change has a high risk of breaking some old code and people doing GNU/Linux distribution builds may wish to see how much is broken in a build with a -std=gnu2x default. gcc/ * ginclude/stdalign.h [defined __STDC_VERSION__ && __STDC_VERSION__ > 201710L]: Disable all content. * ginclude/stdbool.h [defined __STDC_VERSION__ && __STDC_VERSION__ > 201710L] (bool, true, false): Do not define. gcc/c-family/ * c-common.cc (c_common_reswords): Use D_C2X instead of D_CXXONLY for alignas, alignof, bool, false, static_assert, thread_local and true. gcc/c/ * c-parser.cc (c_parser_static_assert_declaration_no_semi) (c_parser_alignas_specifier, c_parser_alignof_expression): Allow for C2x spellings of keywords.

The first part of the following testcase (m1-m3 macros and its use) regressed with my PR89971 fix, but as the m1,m4-m5 and its use part shows, the problem isn't new, we can emit a CPP_PADDING token to avoid it from being adjacent to whatever comes after the __VA_OPT__ (in this case there is nothing afterwards, true). In most cases these CPP_PADDING tokens don't matter, all other callers of cpp_get_token_with_location either ignore CPP_PADDING tokens completely (e.g. c_lex_with_flags) or they just remember them and take them into account when printing stuff whether there should be added whitespace or not (scan_translation_unit + token_streamer::stream). So, I think we should just ignore CPP_PADDING tokens the same way in _cpp_parse_expr. 2022-05-27 Jakub Jelinek <jakub@redhat.com> PR preprocessor/105732 * expr.cc (_cpp_parse_expr): Handle CPP_PADDING by just another token. * c-c++-common/cpp/va-opt-10.c: New test.

When the preprocessor lexes preprocessing numbers in lex_number, it accepts digit separators in more cases than actually permitted in pp-numbers by the standard syntax. One thing this accepts is adjacent digit separators; there is some code to reject those later, but as noted in bug 83873 it fails to cover the case of adjacent digit separators within a floating-point exponent. Accepting adjacent digit separators only results in a missing diagnostic, not in valid code being rejected or being accepted with incorrect semantics, because the correct lexing in such a case would have '' start the following preprocessing tokens, and no valid preprocessing token starts '' while ' isn't valid on its own as a preprocessing token either. So this patch fixes that case by moving the error for adjacent digit separators to lex_number (allowing a more specific diagnostic than if '' were excluded from the pp-number completely). Other cases inappropriately accepted involve digit separators before '.', 'e+', 'e-', 'p+' or 'p-' (or corresponding uppercase variants). In those cases, as shown by the test digit-sep-pp-number.C added, this can result in valid code being wrongly rejected as a result of too many characters being included in the pp-number. So this case is fixed by terminating the pp-number at the correct character according to the standard. That test also covers the case where a digit separator was followed by an identifier-nondigit that is not a nondigit (e.g. a UCN); that case was already handled correctly. Bootstrapped with no regressions for x86_64-pc-linux-gnu. libcpp/ PR c++/83873 PR preprocessor/97604 * lex.c (lex_number): Reject adjacent digit separators here. Do not allow digit separators before '.' or an exponent with sign. * expr.c (cpp_classify_number): Do not check for adjacent digit separators here. gcc/testsuite/ PR c++/83873 PR preprocessor/97604 * g++.dg/cpp1y/digit-sep-neg-2.C, g++.dg/cpp1y/digit-sep-pp-number.C: New tests. * g++.dg/cpp1y/digit-sep-line-neg.C, g++.dg/cpp1y/digit-sep-neg.C: Adjust expected messages.

The following patch uses make_signed_t<size_t> instead of make_signed<size_t>::type in the diagnostics, because the former is shorter. It is true that one can't use make_signed<size_t>::type in C++11 code (which is why I haven't changed it in the testcase which is c++11 effective target), but the message talks about C++23 and make_signed_t is a C++14 and later feature, so I think it is fine. 2021-02-04 Jakub Jelinek <jakub@redhat.com> * expr.c (cpp_classify_number): Use make_signed_t<size_t> instead of make_signed<size_t>::type in the diagnostics. * g++.dg/warn/Wsize_t-literals.C: Expect make_signed_t<size_t> instead of make_signed<size_t>::type in the diagnostics.

Deferred macros are needed for C++ modules. Header units may export macro definitions and undefinitions. These are resolved lazily at the point of (potential) use. (The language specifies that, it's not just a useful optimization.) Thus, identifier nodes grow a 'deferred' field, which fortunately doesn't expand the structure on 64-bit systems as there was padding there. This is non-zero on NT_MACRO nodes, if the macro is deferred. When such an identifier is lexed, it is resolved via a callback that I added recently. That will either provide the macro definition, or discover it there was an overriding undef. Either way the identifier is no longer a deferred macro. Notice it is now possible for NT_MACRO nodes to have a NULL macro expansion. libcpp/ * include/cpplib.h (struct cpp_hashnode): Add deferred field. (cpp_set_deferred_macro): Define.

Our macro use hook passes a location, but doesn't recieve it from the using location. This patch adds the extra location_t parameter and passes it though.

The clever hack of '#define __has_include __has_include' breaks -dD and -fdirectives-only, because that emits definitions. This turns __has_include into a proper builtin macro.

__has_include is funky in that it is macro-like from the POV of #ifdef and friends, but lexes its parenthesize argument #include-like. We were failing the second part of that, because we used a forwarding macro to an internal name, and hence always lexed the argument in macro-parameter context. We componded that by not setting the right flag when lexing, so it didn't even know. Mostly users got lucky. This reimplements the handline. 1) Remove the forwarding, but declare object-like macros that expand to themselves. This satisfies the #ifdef requirement 2) Correctly set angled_brackets when lexing the parameter. This tells the lexer (a) <...> is a header name and (b) "..." is too (not a string). 3) Remove the in__has_include lexer state, just tell find_file that that's what's happenning, so it doesn't emit an error. We lose the (undocumented) ability to #undef __has_include. That may well have been an accident of implementation. There are no tests for it. We gain __has_include behaviour for all users of the preprocessors -- not just the C-family ones that defined a forwarding macro. libcpp/ PR preprocessor/80005 * include/cpplib.h (BT_HAS_ATTRIBUTE): Fix comment. * internal.h (struct lexer_state): Delete in__has_include field.

ISO/IEC TS 18661-3:2015 defines C bindings to IEEE interchange and extended types, in the form of _FloatN and _FloatNx type names with corresponding fN/FN and fNx/FNx constant suffixes and FLTN_* / FLTNX_* <float.h> macros. This patch implements support for this feature in GCC. The _FloatN types, for N = 16, 32, 64 or >= 128 and a multiple of 32, are types encoded according to the corresponding IEEE interchange format (endianness unspecified; may use either the NaN conventions recommended in IEEE 754-2008, or the MIPS NaN conventions, since the choice of convention is only an IEEE recommendation, not a requirement). The _FloatNx types, for N = 32, 64 and 128, are IEEE "extended" types: types extending a narrower format with range and precision at least as big as those specified in IEEE 754 for each extended type (and with unspecified representation, but still following IEEE semantics for their values and operations - and with the set of values being determined by the precision and the maximum exponent, which means that while Intel "extended" is suitable for _Float64x, m68k "extended" is not). These types are always distinct from and not compatible with each other and the standard floating types float, double, long double; thus, double, _Float64 and _Float32x may all have the same ABI, but they are three still distinct types. The type names may be used with _Complex to construct corresponding complex types (unlike __float128, which acts more like a typedef name than a keyword - thus, this patch may be considered to fix PR c/32187). The new suffixes can be combined with GNU "i" and "j" suffixes for constants of complex types (e.g. 1.0if128, 2.0f64i). The set of types supported is implementation-defined. In this GCC patch, _Float32 is SFmode if that is suitable; _Float32x and _Float64 are DFmode if that is suitable; _Float128 is TFmode if that is suitable; _Float64x is XFmode if that is suitable, and otherwise TFmode if that is suitable. There is a target hook to override the choices if necessary. "Suitable" means both conforming to the requirements of that type, and supported as a scalar type including in libgcc. The ABI is whatever the back end does for scalars of that mode (but note that _Float32 is passed without promotion in variable arguments, unlike float). All the existing issues with exceptions and rounding modes for existing types apply equally to the new type names. No GCC port supports a floating-point format suitable for _Float128x. Although there is HFmode support for ARM and AArch64, use of that for _Float16 is not enabled. Supporting _Float16 would require additional work on the excess precision aspects of TS 18661-3: there are new values of FLT_EVAL_METHOD, which are not currently supported in GCC, and FLT_EVAL_METHOD == 0 now means that operations and constants on types narrower than float are evaluated to the range and precision of float. Implementing that, so that _Float16 gets evaluated with excess range and precision, would involve changes to the excess precision infrastructure so that the _Float16 case is enabled by default, unlike the x87 case which is only enabled for -fexcess-precision=standard. Other differences between _Float16 and __fp16 would also need to be disentangled. GCC has some prior support for nonstandard floating-point types in the form of __float80 and __float128. Where these were previously types distinct from long double, they are made by this patch into aliases for _Float64x / _Float128 if those types have the required properties. In principle the set of possible _FloatN types is infinite. This patch hardcodes the four such types for N <= 128, but with as much code as possible using loops over types to minimize the number of places with such hardcoding. I don't think it's likely any further such types will be of use in future (or indeed that formats suitable for _Float128x will actually be implemented). There is a corner case that all _FloatN, for N >= 128 and a multiple of 32, should be treated as keywords even when the corresponding type is not supported; I intend to deal with that in a followup patch. Tests are added for various functionality of the new types, mostly using type-generic headers. The tests use dg-add-options to pass any extra options needed to enable the types; this is wired up to use the same options as for __float128 on powerpc to enable _Float128 and _Float64x, and effective-target keywords for runtime support do the same hardware test as for __float128 to make sure the VSX instructions generated by those options are supported. (Corresponding additions would be needed for _Float16 on ARM as well if that were enabled with -mfp16-format=ieee required to use it rather than unconditionally available. Of course, -mfp16-format=alternative enables use of a format which is not compatible with the requirements of the _Float16 type.) C++ note: no support for the new types or constant suffixes is added for C++. C++ decimal floating-point support was very different from the C support, using class types, and the same may well apply to any future C++ bindings for IEEE interchange and extended types. There is a case, however, for supporting at least *f128 constants in C++, so that code using __float128 can use the newer style for constants throughout rather than needing to use the older *q constants in C++. Also, if built-in functions are added that may provide a way in which the types could leak into C++ code. Fortran note: the float128_type_node used in the Fortran front end is renamed to gfc_float128_type_node, since the semantics are different: in particular, if long double has binary128 format, then the new language-independent float128_type_node is a distinct type that also has binary128 format, but the Fortran node is expected to be NULL in that case. Likewise, Fortran's complex_float128_type_node is renamed to gfc_complex_float128_type_node. PowerPC note: the back end had an inconsistency that if TFmode was binary128, *q constants were TFmode instead of KFmode but __float128 was KFmode. This patch follows the same logic as for *q constants, so that _Float128 prefers TFmode (and __float128 becomes an alias for _Float128). ARM note: __fp16 is promoted to double (by convert_arguments) when passed without a prototype / in variable arguments. But this is only about the argument promotion; it is not handled as promoting in c-common.c:self_promoting_args_p / c-typeck.c:c_type_promotes_to, meaning that a K&R function definition for an argument of type __fp16 corresponds to a prototype with an argument of that type, not to one with an argument of type double, whereas a float argument in a K&R function definition corresponds to a double prototype argument - and the same functions are also what's involved in making va_arg give a warning and generate a call to abort when called with type float. This is preserved by this patch, while arranging for _Float16 not to be promoted when passed without a prototype / in variable arguments (the promotion of float being considered a legacy feature, not applied to any new types in C99 or later). TS 18661-3 extends the set of decimal floating-point types similarly, and adds new constant suffixes for the existing types, but this patch does not do anything regarding that extension. This patch does nothing regarding built-in functions, although type-generic functions such as __builtin_isinf work for the new types and associated tests are included. There are at least two levels of built-in function support possible for these types. The minimal level, implemented in <https://gcc.gnu.org/ml/gcc-patches/2016-06/msg01702.html> (which needs updating to use dg-add-options), adds built-in functions similar to those x86 has for __float128: __builtin_inf* __builtin_huge_val*, __builtin_nan*, __builtin_nans*, __builtin_fabs*, __builtin_copysign*. That would be sufficient for glibc to use the *f128 names for built-in functions by default with *q used only for backwards compatibility when using older GCC versions. That would also allow c_cpp_builtins's flag_building_libgcc code, defining __LIBGCC_%s_FUNC_EXT__, to use such suffixes rather than the present code hardcoding logic about target-specific constant suffixes and how those relate to function suffixes. Full built-in function support would cover the full range of built-in functions for existing floating-point types, adding variants for all the new types, except for a few obsolescent functions and non-type-generic variants of type-generic functions. Some but not all references to such functions in GCC use macros such as CASE_FLT_FN to be type-generic; a fair amount of work would be needed to identify all places to update. Adding all those functions would enable optimizations (for constant arguments and otherwise) for TS 18661-3 functions, but it would also substantially expand the enum listing built-in functions (and we've had problems with the size of that enum in the past), and increase the amount of built-in function initialization to do - I don't know what the startup cost involved in built-in function initialization is, but it would be something to consider when adding such a large set of functions. There are also a range of optimizations, in match.pd and elsewhere, that only operate on the three standard floating-point types. Ideally those would be made generic to all floating-point types, but this patch does nothing in that regard. Special care would be needed regarding making sure library functions to which calls are generated actually exist. For example, if sqrt is called on an argument of type _Float32, and the result converted to _Float32, this is equivalent to doing a square root operation directly on _Float32. But if the user's libm does not have the sqrtf32 function, or the name is not reserved because __STDC_WANT_IEC_60559_TYPES_EXT__ was not defined before including <math.h>, you can only do that optimization if you convert to a call to sqrtf instead. DECIMAL_DIG now relates to all supported floating-point formats, not just float, double and long double; I've raised the question with WG14 of how this relates to the formula for DECIMAL_DIG in C11 not considering this. TS 18661-3 says it also covers non-arithmetic formats only supported by library conversion functions; this patch does not add any target hooks to allow for the case where there are such formats wider than any supported for arithmetic types (where e.g. libc supports conversions involving the binary128 representation, but the _Float128 type is not supported). GCC provides its own <tgmath.h> for some targets. No attempt is made to adapt this to handle the new types. Nothing is done regarding debug info for the new types (see the "Debugger support for __float128 type?" thread on gcc@, Sep/Oct 2015). No __SIZEOF_*__ macros are added for the new types. Nothing is done with do_warn_double_promotion. Nothing is done to include the new types in those determining max_align_t, although properly it should be sufficiently aligned for any of those types. The logic for usual arithmetic conversions in c_common_type relies on TYPE_PRECISION for floating-point types, which is less than ideal (doesn't necessarily correspond to whether one type's values are subset of another); looking in more detail at the formats might be better. But since I included code in build_common_tree_nodes to work around rs6000 KFmode having precision 113 not 128, I think it should work. Ideally one might have errors in generic code for the case where the two types do not have one type's values a subset of the other (which is undefined behavior). But the only case where this can actually occur is mixing IBM long double with binary128 on powerpc, and rs6000_invalid_binary_op deals with that at present. TS 18661-3 does not fully specify the type resulting from the usual arithmetic conversions in the case where two _FloatNx types have the same set of values; I arranged the code to prefer the greater value of N in that case. The __FP_FAST_FMA* macros are not extended to cover the new types, since there are no corresponding built-in functions (if built-in fmafN, fmafNx are added, the macros should be extended, and the new macros documented). Also, only a limited set of modes is handled in mode_has_fma. Diagnostics relating to the use of the new types with -pedantic do not try to distinguish them from purely nonstandard types such as __int128 and constant suffixes such as *q. If you use an unsupported _FloatN / _FloatNx type you get a warning about the type defaulting to int after the warning about the type not being supported. That's less than ideal, but it's also a pre-existing condition if you use __int128 on a 32-bit system where it's unsupported. Bootstrapped with no regressions on x86_64-pc-linux-gnu. Other back-end changes minimally tested by building cc1 for ia64-linux-gnu, powerpc64le-linux-gnu, pdp11-none (the last failed for unrelated reasons).
