2022-10-14middle-end, c++, i386, libgcc: std::bfloat16_t and __bf16 arithmetic supportJakub Jelinek1-0/+16
Here is a complete patch to add std::bfloat16_t support on x86 (AArch64 and ARM left for later). Almost no BFmode optabs are added by the patch, so for binops/unops it extends to SFmode first and then truncates back to BFmode. For {HF,SF,DF,XF,TF}mode -> BFmode conversions libgcc has implementations of all those conversions so that we avoid double rounding, for BFmode -> {DF,XF,TF}mode conversions to avoid growing libgcc too much it emits BFmode -> SFmode conversion first and then converts to the even wider mode, neither step should be imprecise. For BFmode -> HFmode, it first emits a precise BFmode -> SFmode conversion and then SFmode -> HFmode, because neither format is subset or superset of the other, while SFmode is superset of both. expr.cc then contains a -ffast-math optimization of the BF -> SF and SF -> BF conversions if we don't optimize for space (and for the latter if -frounding-math isn't enabled either). For x86, perhaps truncsfbf2 optab could be defined for TARGET_AVX512BF16 but IMNSHO should FAIL if !flag_finite_math || flag_rounding_math || !flag_unsafe_math_optimizations, because I think the insn doesn't raise on sNaNs, hardcodes round to nearest and flushes denormals to zero. By default (unless x86 -fexcess-precision=16) we use float excess precision for BFmode, so truncate only on explicit casts and assignments. The patch introduces a single __bf16 builtin - __builtin_nansf16b, because (__bf16) __builtin_nansf ("") will drop the sNaN into qNaN, and uses f16b suffix instead of bf16 because there would be ambiguity on log vs. logb - __builtin_logbf16 could be either log with bf16 suffix or logb with f16 suffix. In other cases libstdc++ should mostly use __builtin_*f for std::bfloat16_t overloads (we have a problem with std::nextafter though but that one we have also for std::float16_t). 2022-10-14 Jakub Jelinek <jakub@redhat.com> gcc/ * tree-core.h (enum tree_index): Add TI_BFLOAT16_TYPE. * tree.h (bfloat16_type_node): Define. * tree.cc (excess_precision_type): Promote bfloat16_type_mode like float16_type_mode.

2022-10-14c++: Implement excess precision support for C++ [PR107097, PR323]Jakub Jelinek1-4/+1
The following patch implements excess precision support for C++. Like for C, it uses EXCESS_PRECISION_EXPR tree to say that its operand is evaluated in excess precision and what the semantic type of the expression is. In most places I've followed what the C FE does in similar spots, so e.g. for binary ops if one or both operands are already EXCESS_PRECISION_EXPR, strip those away or for operations that might need excess precision (+, -, *, /) check if the operands should use excess precision and convert to that type and at the end wrap into EXCESS_PRECISION_EXPR with the common semantic type. This patch follows the C99 handling where it differs from C11 handling. There are some cases which needed to be handled differently, the C FE can just strip EXCESS_PRECISION_EXPR (replace it with its operand) when handling explicit cast, but that IMHO isn't right for C++ - the discovery what exact conversion should be used (e.g. if user conversion or standard or their sequence) should be decided based on the semantic type (i.e. type of EXCESS_PRECISION_EXPR), and that decision continues in convert_like* where we pick the right user conversion, again, if say some class has ctor from double and long double and we are on ia32 with standard excess precision promoting float/double to long double, then we should pick the ctor from double. Or when some other class has ctor from just double, and EXCESS_PRECISION_EXPR semantic type is float, we should choose the user ctor from double, but actually just convert the long double excess precision to double and not to float first. We need to make sure even identity conversion converts from excess precision to the semantic one though, but if identity is chained with other conversions, we don't want the identity next_conversion to drop to semantic precision only to widen afterwards. The existing testcases tweaks were for cases on i686-linux where excess precision breaks those tests, e.g. if we have double d = 4.2; if (d == 4.2) then it does the expected thing only with -fexcess-precision=fast, because with -fexcess-precision=standard it is actually double d = 4.2; if ((long double) d == 4.2L) where 4.2L is different from 4.2. I've added -fexcess-precision=fast to some tests and changed other tests to use constants that are exactly representable and don't suffer from these excess precision issues. There is one exception, pr68180.C looks like a bug in the patch which is also present in the C FE (so I'd like to get it resolved incrementally in both). Reduced testcase: typedef float __attribute__((vector_size (16))) float32x4_t; float32x4_t foo(float32x4_t x, float y) { return x + y; } with -m32 -std=c11 -Wno-psabi or -m32 -std=c++17 -Wno-psabi it is rejected with: pr68180.c:2:52: error: conversion of scalar ‘long double’ to vector ‘float32x4_t’ {aka ‘__vector(4) float’} involves truncation but without excess precision (say just -std=c11 -Wno-psabi or -std=c++17 -Wno-psabi) it is accepted. Perhaps we should pass down the semantic type to scalar_to_vector and use the semantic type rather than excess precision type in the diagnostics. 2022-10-14 Jakub Jelinek <jakub@redhat.com> PR middle-end/323 PR c++/107097 gcc/ * doc/invoke.texi (-fexcess-precision=standard): Mention that the option now also works in C++. gcc/c-family/ * c-common.def (EXCESS_PRECISION_EXPR): Remove comment part about the tree being specific to C/ObjC. * c-opts.cc (c_common_post_options): Handle flag_excess_precision in C++ the same as in C. * c-lex.cc (interpret_float): Set const_type to excess_precision () even for C++. gcc/cp/ * parser.cc (cp_parser_primary_expression): Handle EXCESS_PRECISION_EXPR with REAL_CST operand the same as REAL_CST. * cvt.cc (cp_ep_convert_and_check): New function. * call.cc (build_conditional_expr): Add excess precision support.

2022-10-06c++, c: Implement C++23 P1774R8 - Portable assumptions [PR106654]Jakub Jelinek1-0/+2
The following patch implements C++23 P1774R8 - Portable assumptions paper, by introducing support for [[assume (cond)]]; attribute for C++. In addition to that the patch adds [[gnu::assume (cond)]]; and __attribute__((assume (cond))); support to both C and C++. As described in C++23, the attribute argument is conditional-expression rather than the usual assignment-expression for attribute arguments, the condition is contextually converted to bool (for C truthvalue conversion is done on it) and is never evaluated at runtime. For C++ constant expression evaluation, I only check the simplest conditions for undefined behavior, because otherwise I'd need to undo changes to *ctx->global which happened during the evaluation (but I believe the spec allows that and we can further improve later). The patch uses a new internal function, .ASSUME, to hold the condition in the FEs. At gimplification time, if the condition is simple/without side-effects, it is gimplified as if (cond) ; else __builtin_unreachable (); and otherwise for now dropped on the floor. The intent is to incrementally outline the conditions into separate artificial functions and use .ASSUME further to tell the ranger and perhaps other optimization passes about the assumptions, as detailed in the PR. When implementing it, I found that assume entry hasn't been added to https://eel.is/c++draft/cpp.cond#6 Jonathan said he'll file a NB comment about it, this patch assumes it has been added into the table as 202207L when the paper has been voted in. With the attributes for both C/C++, I'd say we don't need to add __builtin_assume with similar purpose, especially when __builtin_assume in LLVM is just weird. It is strange for side-effects in function call's argument not to be evaluated, and LLVM in that case (annoyingly) warns and ignores the side-effects (but doesn't do then anything with it), if there are no side-effects, it will work like our if (!cond) __builtin_unreachable (); 2022-10-06 Jakub Jelinek <jakub@redhat.com> PR c++/106654 gcc/ * internal-fn.def (ASSUME): New internal function. * internal-fn.h (expand_ASSUME): Declare. * internal-fn.cc (expand_ASSUME): Define. * gimplify.cc (gimplify_call_expr): Gimplify IFN_ASSUME. * fold-const.h (simple_condition_p): Declare. * fold-const.cc (simple_operand_p_2): Rename to ...

2022-09-29c: C2x noreturn attributeJoseph Myers1-0/+3
C2x adds a standard [[noreturn]] attribute (which can also be spelt [[_Noreturn]] for use with <stdnoreturn.h>), so allowing non-returning functions to be declared in a manner compatible with C++; the _Noreturn function specifier remains available but is marked obsolescent. Implement this attribute. It's more restricted than GNU __attribute__ ((noreturn)) - that allows function pointers but using the standard attribute on a function pointer is a constraint violation. Thus, the attribute gets its own handler that checks for a FUNCTION_DECL before calling the handler for the GNU attribute. Tests for the attribute are based on those for C11 _Noreturn and for other C2x attributes.

2022-09-27c++: Implement P1467R9 - Extended floating-point types and standard names ↵Jakub Jelinek1-2/+18
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.

2022-09-02c/c++: new warning: -Wxor-used-as-pow [PR90885]David Malcolm1-1/+5
PR c/90885 notes various places in real-world code where people have written C/C++ code that uses ^ (exclusive or) where presumbably they meant exponentiation. For example https://codesearch.isocpp.org/cgi-bin/cgi_ppsearch?q=2%5E32&search=Search currently finds 11 places using "2^32", and all of them appear to be places where the user means 2 to the power of 32, rather than 2 exclusive-orred with 32 (which is 34). This patch adds a new -Wxor-used-as-pow warning to the C and C++ frontends to complain about ^ when the left-hand side is the decimal constant 2 or the decimal constant 10. This is the same name as the corresponding clang warning: https://clang.llvm.org/docs/DiagnosticsReference.html#wxor-used-as-pow As per the clang warning, the warning suggests converting the left-hand side to a hexadecimal constant if you really mean xor, which suppresses the warning (though this patch implements a fix-it hint for that, whereas the clang implementation only has a fix-it hint for the initial suggestion of exponentiation). I initially tried implementing this without checking for decimals, but this version had lots of false positives. Checking for decimals requires extending the lexer to capture whether or not a CPP_NUMBER token was decimal. I added a new DECIMAL_INT flag to cpplib.h for this. Unfortunately, c_token and cp_tokens both have only an unsigned char for their flags (as captured by c_lex_with_flags), whereas this would add the 12th flag to cpp_tokens. Of the first 8 flags, all but BOL are used in the C or C++ frontends, but BOL is not, so I moved that to a higher position, using its old value for the new DECIMAL_INT flag, so that it is representable within an unsigned char. Example output: demo.c:5:13: warning: result of '2^8' is 10; did you mean '1 << 8' (256)? [-Wxor-used-as-pow] 5 | int t2_8 = 2^8; | ^ | -- | 1<< demo.c:5:12: note: you can silence this warning by using a hexadecimal constant (0x2 rather than 2) 5 | int t2_8 = 2^8; | ^ | 0x2 demo.c:21:15: warning: result of '10^6' is 12; did you mean '1e6'?

2022-08-31c: C2x attributes fixes and updatesJoseph Myers1-3/+5
Implement some changes to the currently supported C2x standard attributes that have been made to the specification since they were first implemented in GCC, and some consequent changes: * maybe_unused is now supported on labels. In fact that was already accidentally supported in GCC as a result of sharing the implementation with __attribute__ ((unused)), but needed to be covered in the tests. * As part of the support for maybe_unused on labels, its __has_c_attribute value changed. * The issue of maybe_unused accidentally being already supported on labels showed up the lack of tests for other standard attributes being incorrectly applied to labels; add such tests. * Use of fallthrough or nodiscard attributes on labels already properly resulted in a pedwarn. For the deprecated attribute, however, there was only a warning, and the wording "'deprecated' attribute ignored for 'void'" included an unhelpful "for 'void'". Arrange for the case of the deprecated attribute on a label to be checked for separately and result in a pedwarn. As with inappropriate uses of fallthrough (see commit 6c80b1b56dec2691436f3e2676e3d1b105b01b89), it seems reasonable for this pedwarn to apply regardless of whether [[]] or __attribute__ was used and regardless of whether C or C++ is being compiled. * Attributes on case or default labels (the standard syntax supports attributes on all kinds of labels) were quietly ignored, whether or not appropriate for use in such a context, because they weren't passed to decl_attributes at all. (Note where I'm changing the do_case prototype that such a function is actually only defined in the C front end, not for C++, despite the declaration being in c-common.h.) * A recent change as part of the editorial review in preparation for the C2x CD ballot has changed the __has_c_attribute value for fallthrough to 201910 to reflect when that attribute was actually voted into the working draft. Bootstrapped with no regressions for x86_64-pc-linux-gnu. gcc/c-family/ * c-attribs.cc (handle_deprecated_attribute): Check and pedwarn for LABEL_DECL. * c-common.cc (c_add_case_label): Add argument ATTRS.
