2020-11-17float.h: Handle C2x __STDC_WANT_IEC_60559_EXT__Joseph Myers1-1/+2
TS 18661-1 and 18661-2 have various definitions conditional on __STDC_WANT_IEC_60559_BFP_EXT__ and __STDC_WANT_IEC_60559_DFP_EXT__ macros. When those TSes were integrated into C2x, most of the feature test macro conditionals were removed (with declarations for decimal FP becoming conditional only on whether decimal FP is supported by the implementation and those for binary FP becoming unconditionally required). A few tests of those feature test macros remained for declarations that appeared only in Annex F and not in the main part of the standard. A change accepted for C2x at the last WG14 meeting (but not yet added to the working draft in git) was to replace both those macros by __STDC_WANT_IEC_60559_EXT__; if __STDC_WANT_IEC_60559_EXT__ is defined, the specific declarations in the headers will then depend on which features are supported by the implementation, as for declarations not controlled by a feature test macro at all. Thus, add a check of __STDC_WANT_IEC_60559_EXT__ for CR_DECIMAL_DIG in float.h, the only case of this change relevant to GCC.

2020-11-17float.h: C2x decimal signaling NaN macrosJoseph Myers1-0/+8
C2x adds macros for decimal floating-point signaling NaNs to <float.h>. Add these macros to GCC's <float.h> implementation. Note that the current C2x draft has these under incorrect names D32_SNAN, D64_SNAN, D128_SNAN. The intent was to change the naming convention to be consistent with other <float.h> macros when they were moved to <float.h>, so DEC32_SNAN, DEC64_SNAN, DEC128_NAN, which this patch uses (as does the current draft integration of TS 18661-3 as an Annex to C2x, for its _Decimal* and _Decimal*x types).

2020-11-17float.h: C2x NaN and Inf macrosJoseph Myers1-0/+66
C2x adds macros for NaNs and infinities to <float.h>, some of them previously in <math.h> (and some still in <math.h> as well in C2x as an obsolescent feature). Add these macros to GCC's <float.h> implementation. This omits the macros for DFP signaling NaNs, leaving those to be added in a separate patch. However, it includes the _FloatN / _FloatNx macros (conditional on __STDC_WANT_IEC_60559_TYPES_EXT__) in the current draft version of the integration of TS 18661-3 into C2x as an Annex. As GCC allows duplicate macro definitions with different expansions in system headers, it should be OK if <math.h> defines INFINITY or NAN with a slightly different expansion (e.g. different choice of whether there is whitespace between tokens); tests are added including <float.h> and <math.h> in either order. Because <float.h> uses #undef on all macros before defining them, even with -Wsystem-headers there could only ever be issues when <math.h> is included after <float.h>.

2020-10-29stdbool.h: Update true and false expansions for C2xJoseph Myers1-0/+5
C2x has changed the expansions of the true and false macros in <stdbool.h> so that they have type _Bool (including in #if conditions, i.e. an unsigned type in that context). Use the new expansions in GCC's <stdbool.h> for C2x. See bug 82272 for related discussion (but this patch does *not* implement the warning discussed there). Note that it's possible there may be a further change to make bool, true and false keywords (there was support in principle for that at the April WG14 meeting). But currently these expansions of type _Bool are what C2x requires and there isn't actually a paper before WG14 at present that would introduce the new keywords.

2020-09-02c++: Stop defining true, false and bool as macros in <stdbool.h>Jonathan Wakely1-7/+0
Since r216679 these macros have only been defined in C++98 mode, rather than all modes. That is permitted as a GNU extension because that header doesn't exist in the C++ standard until C++11, so we can make it do whatever we want for C++98. But as discussed in the PR c++/60304 comments, these macros shouldn't ever be defined for C++. This patch removes the macro definitions for C++98 too. The new test already passed for C++98 (and the conversion is ill-formed in C++11 and later) so this new test is arguably unnecessary. gcc/ChangeLog: PR c++/60304 * ginclude/stdbool.h (bool, false, true): Never define for C++. gcc/testsuite/ChangeLog: PR c++/60304 * g++.dg/warn/Wconversion-null-5.C: New test.

2019-11-13Add C2x *_NORM_MAX constants to <float.h>.Joseph Myers1-0/+12
C2x adds <float.h> constants FLT_NORM_MAX, DBL_NORM_MAX and LDBL_NORM_MAX. These are for the maximum "normalized" finite floating-point number, where the given definition of normalized is that all possible values with MANT_DIG significand digits (leading one not zero) can be represented with that exponent. The effect of that definition is that these macros are the same as the corresponding MAX macros for all formats except IBM long double, where the NORM_MAX value has exponent 1 smaller than the MAX one so that all 106 digits can be 1. This patch adds those macros to GCC. They are only defined for float, double and long double; C2x does not include such macros for DFP types, and while the integration of TS 18661-3 into C2x has not yet occurred, the draft proposed text does not add them for the _FloatN / _FloatNx types (where they would always be the same as the MAX macros). Bootstrapped with no regressions on x86_64-pc-linux-gnu. Also tested compilation of the new test for powerpc-linux-gnu to confirm the check of LDBL_NORM_MAX in the IBM long double case does get properly optimized out. gcc: * ginclude/float.c [__STDC_VERSION__ > 201710L] (FLT_NORM_MAX, DBL_NORM_MAX, LDBL_NORM_MAX): Define. * real.c (get_max_float): Add norm_max argument. * real.h (get_max_float): Update prototype. * builtins.c (fold_builtin_interclass_mathfn): Update calls to get_max_float. gcc/c-family: * c-cppbuiltin.c (builtin_define_float_constants): Also define NORM_MAX constants.

2019-10-10Update DFP macros in float.h for C2x and TS 18661-2.Joseph Myers1-12/+35
GCC's <float.h> includes various macros for decimal floating-point types, defined if __STDC_WANT_DEC_FP__, as defined in TS 24732. TS 18661-2 and C2X make some changes to those macros. In TS 18661-2, they are to be defined if __STDC_WANT_IEC_60559_DFP_EXT__, and the *_SUBNORMAL_MIN macros are renamed to *_TRUE_MIN. In C2X, the macros are to be defined whenever DFP is supported, without needing any feature test macro to be defined. This patch updates the header accordingly. There is no existing predefined macro for whether the target supports DFP; rather than adding a new macro for that purpose, this patch changes the predefined macros used in <float.h> so that they are only defined when DFP is supported and thus can be used as conditionals; this is the same way predefined macros for _FloatN and _FloatNx types work. Although formally TR 24732 and TS 18661-2 say nothing about implementations lacking DFP support, it seems appropriate to avoid defining the macros in <float.h>, in the absence of DFP support, even if the respective feature test macros are defined. Bootstrapped with no regressions on x86_64-pc-linux-gnu. Also tested the c2x-float-no-dfp-* tests for aarch64-linux-gnu to make sure they do pass in a no-DFP configuration. gcc: * ginclude/float.h [!__DEC32_MANT_DIG__]: Do not define DFP macros.

2019-10-03Define WIDTH macros for C2x.Joseph Myers1-2/+3
As part of the integration of TS 18661-1 into C2x, many features became unconditional features not depending on any feature test macro being defined. This patch updates the conditionals on the *_WIDTH macros in limits.h and stdint.h accordingly so that they are defined for C2x. The macro CR_DECIMAL_DIG in float.h does still require __STDC_WANT_IEC_60559_BFP_EXT__ to be defined, and a test for this is added.

2019-09-10[ARM/FDPIC v6 06/24] [ARM] FDPIC: Add support for c++ exceptionsChristophe Lyon1-1/+1
The main difference with existing support is that function addresses are function descriptor addresses instead. This means that all code dealing with function pointers now has to cope with function descriptors instead. For the same reason, Linux kernel helpers can no longer be called by dereferencing their address, so we implement wrappers that directly call the kernel helpers.

2017-11-15Add __builtin_tgmath for better tgmath.h implementation (bug 81156).Joseph Myers1-63/+19
Various implementations of C99/C11 <tgmath.h> have the property that their macro expansions contain many copies of the macro arguments, so resulting in exponential blowup of the size of macro expansions where a call to such a macro contains other such calls in the macro arguments. This patch adds a (C-only) language feature __builtin_tgmath designed to avoid this problem by implementing the <tgmath.h> function selection rules directly in the compiler. The effect is that type-generic macros can be defined simply as #define pow(a, b) __builtin_tgmath (powf, pow, powl, \ cpowf, cpow, cpowl, a, b) as in the example added to the manual, with each macro argument expanded exactly once. The details of __builtin_tgmath are as described in the manual. This is C-only since C++ uses function overloading and just defines <ctgmath> to include <ccomplex> and <cmath>. __builtin_tgmath handles C99/C11 type-generic macros, and _FloatN, _FloatNx and decimal floating-point types (following the proposed resolution to the floating-point TS DR#9 that makes the rules for finding a common type from arguments to a type-generic macro follow the usual arithmetic conversions after adjustment of integer arguments to _Decimal64 or double - or to _Complex double in the case of GNU complex integer arguments). Type-generic macros for functions from TS 18661 that round their results to a narrower type are handled, but there are still some unresolved questions regarding such macros so further changes in that regard may be needed in future. The current implementation follows an older version of the DR#13 resolution (allowing a function for a wide-enough argument type to be selected if no exactly-matching function is available), but with appropriate calls to __builtin_tgmath is still fully compatible with the latest version of the resolution (not yet in the DR log), and allowing such not-exactly-matching argument types to be chosen in that case avoids needing another special case to treat integers as _Float64 instead of double in certain cases. Regarding other possible language/library features, not currently implemented in GCC: * Imaginary types could be naturally supported by allowing cases where the type-generic type is an imaginary type T and arguments or return types may be T (as at present), or the corresponding real type to T (as at present), or (new) the corresponding real type if T is real or imaginary but T if T is complex. (tgmath.h would need a series of functions such as static inline _Imaginary double __sin_imag (_Imaginary double __x) { return _Imaginary_I * sinh (__imag__ __x); } to be used in __builtin_tgmath calls.) * __builtin_tgmath would use the constant rounding direction in the presence of support for the FENV_ROUND / FENV_DEC_ROUND pragmas. Support for those would also require a new __builtin_<something> to cause a non-type-generic call to use the constant rounding direction (it seems cleaner to add a new __builtin_<something> when required than to make __builtin_tgmath handle a non-type-generic case with only one function argument). * TS 18661-5 __STDC_TGMATH_OPERATOR_EVALUATION__ would require new __builtin_<something> that evaluates with excess range and precision like arithmetic operators do. * The proposed C bindings for IEEE 754-2018 augmented arithmetic operations involve struct return types. As currently implemented __builtin_tgmath does not handle those, but support could be added. There are many error cases that the implementation diagnoses. I've tried to ensure reasonable error messages for erroneous uses of __builtin_tgmath, but the errors for erroneous uses of the resulting type-generic macros (that is, when the non-function arguments have inappropriate types) are more important as they are more likely to be seen by users. GCC's own tgmath.h, as used for some targets, is updated in this patch. I've tested those changes minimally, via adjusting gcc.dg/c99-tgmath-* locally to use that tgmath.h version. I've also run the glibc testsuite (which has much more thorough tests of correctness of tgmath.h function selection) with a glibc patch to use __builtin_tgmath in glibc's tgmath.h.

2016-09-19Define TS 18661-1 CR_DECIMAL_DIG in <float.h>.Joseph Myers1-0/+7
TS 18661-1 defines a macro CR_DECIMAL_DIG in <float.h>, for the number of decimal digits for which conversions between decimal character strings and (IEEE) binary formats, in both directions, are correctly rounded. This patch implements support for this macro in GCC's <float.h>. The definition __UINTMAX_MAX__ is the right one for GCC's conversions of floating constants, since I made those use MPFR to make them correctly rounding. The macro also covers standard library functions such as strtod and printf. The definition is also correct for current glibc. If any targets' libcs support correct rounding in a way that conforms to TS 18661-1 with a smaller value of CR_DECIMAL_DIG, making <float.h> reflect that could not be done in isolation without changes to the interpretation of floating constants as well, since a smaller CR_DECIMAL_DIG requires double rounding of floating constants (first to CR_DECIMAL_DIG decimal digits, then to the desired binary format).

2016-09-19Make max_align_t respect _Float128.Joseph Myers1-0/+8
The _FloatN, _FloatNx, _DecimalN and _DecimalNx types are specified in such a way that they are basic types, meaning that max_align_t must be at least as aligned as those types. On 32-bit x86, max_align_t is currently 8-byte aligned, but _Decimal128 and _Float128 are 16-byte aligned, so the alignment of max_align_t needs to increase to meet the standard requirements for these types. This patch implements such an increase. Because max_align_t needs to be usable for C++ as well as for C, <stddef.h> can't actually refer to _Float128, but needs to use __float128 (or some other notation for the type) instead. And since __float128 is architecture-specific, there isn't a preprocessor conditional that means "__float128 is available" (whereas one could test __FLT128_MANT_DIG__ to see if _Float128 is available; __SIZEOF_FLOAT128__ is available on x86 only). But I believe the only case that actually has an alignment problem here is 32-bit x86, and <stddef.h> already has lots of conditional specific to particular architectures or OSes, so this patch uses a conditional on __i386__; that also is the minimal change that ensures neither size nor alignment of max_align_t is changed in any case other than where it is necessary. If any other architectures turn out to have such an issue, it will show up as failures of one of the testcases added by this patch. Such an increase is of course an ABI change, but a reasonably safe one, in that max_align_t doesn't tend to appear in library interfaces (rather, it's something to use when writing allocators and similar code; most matches found on codesearch.debian.net look like copies of the gnulib stddef.h module rather than anything actually using max_align_t at all). max_align_t_align has a corresponding change (adding _Float128 to the types considered). (I think glibc malloc alignment should also increase to 16-byte on 32-bit x86 so it works for allocating objects of these types, which is now straightforward given the fix made for 32-bit powerpc.) Bootstrapped with no regressions on x86_64-pc-linux-gnu, and spot-tested with -m32 that the new float128-align.c test now compiles where previously it didn't. gcc: * ginclude/stddef.h (max_align_t) [__i386__]: Add __float128 element. gcc/c-family: * c-common.c (max_align_t_align): Also consider alignment of float128_type_node. gcc/testsuite: * gcc.dg/float128-align.c, gcc.dg/float128x-align.c, gcc.dg/float16-align.c, gcc.dg/float32-align.c, gcc.dg/float32x-align.c, gcc.dg/float64-align.c, gcc.dg/float64x-align.c, gcc.dg/floatn-align.h: New tests.

2016-09-09Define TS 18661-1 type width macros in <limits.h> and <stdint.h>.Joseph Myers1-0/+101
TS 18661-1 defines <limits.h> and <stdint.h> macros for widths of standard integer types and the typedefs defined in, or whose limits are defined in, <stdint.h>. (The connection to the main floating-point subject matter of TS 18661-1 is that these are intended to be used with the fromfp functions to convert from floating point to integer types of any width in any rounding direction, though these macros may be of more general use.) This patch implements support for these macros in GCC's <limits.h> and <stdint.h>. To avoid needing to implement fixincludes for system headers where GCC wraps the system libc's <stdint.h> in hosted mode, the test for the <stdint.h> macros uses -ffreestanding (I'll add the macros to glibc's headers separately) - but as usual for new features in these headers, platforms (primarily OpenBSD) that use USER_H to avoid using GCC's headers at all will have failures until the system headers have the feature added or appropriate fixincludes are implemented. The header macros are implemented using appropriate new predefined macros, with the code avoiding defining more such macros than necessary (so one predefined macro suffices for corresponding signed and unsigned types, while no such predefined macros are needed for the exact-width types such as int8_t). Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc: * doc/cpp.texi (__SCHAR_WIDTH__, __SHRT_WIDTH__, __INT_WIDTH__) (__LONG_WIDTH__, __LONG_LONG_WIDTH__, __PTRDIFF_WIDTH__) (__SIG_ATOMIC_WIDTH__, __SIZE_WIDTH__, __WCHAR_WIDTH__) (__WINT_WIDTH__, __INT_LEAST8_WIDTH__, __INT_LEAST16_WIDTH__) (__INT_LEAST32_WIDTH__, __INT_LEAST64_WIDTH__) (__INT_FAST8_WIDTH__, __INT_FAST16_WIDTH__, __INT_FAST32_WIDTH__) (__INT_FAST64_WIDTH__, __INTPTR_WIDTH__, __INTMAX_WIDTH__): Document. * ginclude/stdint-gcc.h [__STDC_WANT_IEC_60559_BFP_EXT__]: Define width macros from TS 18661-1. * glimits.h [__STDC_WANT_IEC_60559_BFP_EXT__]: Likewise. gcc/c-family: * c-cppbuiltin.c (builtin_define_type_width): New function.

2016-08-19Implement C _FloatN, _FloatNx types.Joseph Myers1-1/+182
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).

2015-11-18Add out-of-line versions of some <stdatomic.h> functions (PR c/65083).Joseph Myers1-0/+7
PR c/65083 notes that some functions in <stdatomic.h> are normal functions, not generic functions, and so need to have out-of-line copies that can be called when macro expansion is suppressed (unlike the generic functions where DR#419 makes it undefined if you suppress a macro expansion). This patch adds such out-of-line definitions in libatomic for those six functions, at a new LIBATOMIC_1.2 symbol version, as trivial wrappers to the <stdatomic.h> macros, along with declarations of those functions in <stdatomic.h>. Tests are added that are based on the corresponding tests for the macros, but with parentheses around the function names to force the out-of-line functions to be used. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc: * ginclude/stdatomic.h (atomic_thread_fence, atomic_signal_fence) (atomic_flag_test_and_set, atomic_flag_test_and_set_explicit) (atomic_flag_clear, atomic_flag_clear_explicit): Declare as functions before defining as macros. gcc/testsuite: * gcc.dg/atomic/stdatomic-fence-2.c, gcc.dg/atomic/stdatomic-flag-2.c: New tests. libatomic: * fence.c, flag.c: New files. * Makefile.am (libatomic_la_SOURCES): Add fence.c and flag.c. * Makefile.in: Regenerate. * configure.ac (libtool_VERSION): Change to 3:0:2. * configure: Regenerate. * libatomic.map (LIBATOMIC_1.2): New symbol version.
