2021-11-01diagnostics: escape non-ASCII source bytes for certain diagnosticsDavid Malcolm1-1/+5
This patch adds support to GCC's diagnostic subsystem for escaping certain bytes and Unicode characters when quoting source code. Specifically, this patch adds a new flag rich_location::m_escape_on_output which is a hint from a diagnostic that non-ASCII bytes in the pertinent lines of the user's source code should be escaped when printed. The patch sets this for the following diagnostics: - when complaining about stray bytes in the program (when these are non-printable) - when complaining about "null character(s) ignored"); - for -Wnormalized= (and generate source ranges for such warnings) The escaping is controlled by a new option: -fdiagnostics-escape-format=[unicode|bytes] For example, consider a diagnostic involing a source line containing the string "before" followed by the Unicode character U+03C0 ("GREEK SMALL LETTER PI", with UTF-8 encoding 0xCF 0x80) followed by the byte 0xBF (a stray UTF-8 trailing byte), followed by the string "after", where the diagnostic highlights the U+03C0 character. By default, this line will be printed verbatim to the user when reporting a diagnostic at it, as: beforeπXafter ^ (using X for the stray byte to avoid putting invalid UTF-8 in this commit message) If the diagnostic sets the "escape" flag, it will be printed as: before<U+03C0><BF>after ^~~~~~~~ with -fdiagnostics-escape-format=unicode (the default), or as: before<CF><80><BF>after ^~~~~~~~ if the user supplies -fdiagnostics-escape-format=bytes. This only affects how the source is printed; it does not affect how column numbers that are printed (as per -fdiagnostics-column-unit= and -fdiagnostics-column-origin=). gcc/c-family/ChangeLog: * c-lex.c (c_lex_with_flags): When complaining about non-printable CPP_OTHER tokens, set the "escape on output" flag. gcc/ChangeLog: * common.opt (fdiagnostics-escape-format=): New.

2020-11-18preprocessor: C++ module-directivesNathan Sidwell1-1/+4
C++20 modules introduces a new kind of preprocessor directive -- a module directive. These are directives but without the leading '#'. We have to detect them by sniffing the start of a logical line. When detected we replace the initial identifiers with unspellable tokens and pass them through to the language parser the same way deferred pragmas are. There's a PRAGMA_EOL at the logical end of line too. One additional complication is that we have to do header-name lexing after the initial tokens, and that requires changes in the macro-aware piece of the preprocessor. The above sniffer sets a counter in the lexer state, and that triggers at the appropriate point. We then do the same header-name lexing that occurs on a #include directive or has_include pseudo-macro. Except that the header name ends up in the token stream. A couple of token emitters need to deal with the new token possibility. gcc/c-family/ * c-lex.c (c_lex_with_flags): CPP_HEADER_NAMEs can now be seen. libcpp/ * include/cpplib.h (struct cpp_options): Add module_directives option.

2020-11-12c: C2x __has_c_attributeJoseph Myers1-28/+39
C2x adds the __has_c_attribute preprocessor operator, similar to C++ __has_cpp_attribute. GCC implements __has_cpp_attribute as exactly equivalent to __has_attribute. (The documentation says they differ regarding the values returned for standard attributes, but that's actually only a matter of the particular nonzero value returned not being specified in the documentation for __has_attribute; the implementation makes no distinction between the two.) I don't think having them exactly equivalent is actually correct, either for __has_cpp_attribute or for __has_c_attribute. Specifically, I think it is only correct for __has_cpp_attribute or __has_c_attribute to return nonzero if the given attribute is supported, with the particular pp-tokens passed to __has_cpp_attribute or __has_c_attribute, with [[]] syntax, not if it's only accepted in __attribute__ or with gnu:: added in [[]]. For example, they should return nonzero for gnu::packed, but zero for plain packed, because [[gnu::packed]] is accepted but [[packed]] is ignored as not a standard attribute. This patch implements that for __has_c_attribute, leaving any changes to __has_cpp_attribute for the C++ maintainers. A new BT_HAS_STD_ATTRIBUTE is added for __has_c_attribute (which I think, based on the above, would actually be correct to use for __has_cpp_attribute as well). The code in c_common_has_attribute that deals with scopes has its C++ conditional removed; instead, whether the language is C or C++ is used only to determine the numeric values returned for standard attributes (and which standard attributes are handled there at all). A new argument is passed to c_common_has_attribute to distinguish BT_HAS_STD_ATTRIBUTE from BT_HAS_ATTRIBUTE, and that argument is used to stop attributes with no scope specified from being accepted with __has_c_attribute unless they are one of the known standard attributes and so handled specially. Although the standard specify constants ending with 'L' as the values for the standard attributes, there is no correctness issue with the lack of code in GCC to add that 'L' to the expansion: __has_c_attribute and __has_cpp_attribute are expanded in #if after other macro expansion has occurred, with no semantics being specified if they occur outside #if, so there is no way for a conforming program to inspect the exact text of the expansion of those macros, only to use the resulting pp-number in a #if expression, where long and int have the same set of values.

2020-11-01Objective-C/C++ : Improve '@' keyword locations.Iain Sandoe1-0/+4
When we are lexing tokens for Objective-C, we combine '@' tokens with a following keyword (when that keyword is a valid Objective-C one or, for Objective-C, one of the C++ keywords that can appear in this position). The responsibility is passed on to the parser to validate the resulting combination. The combination of tokens was being done without applying the rule to their locations - so that we get: @property ^ instead of what the user might expect: @property ^~~~~~~~~ This patch combines the source range of the keyword with that of the '@' sign - which improves diagnostics. gcc/c-family/ChangeLog: * c-lex.c (c_lex_with_flags): When combining '@' with a keyword for Objective-C, combine the location ranges too.

2019-11-25Prevent all uses of DFP when unsupported (PR c/91985).Joseph Myers1-1/+6
Code that directly uses _Decimal* types on architectures not supporting DFP is properly diagnosed ("error: decimal floating-point not supported for this target"), via a call to targetm.decimal_float_supported_p, if the _Decimal32, _Decimal64 or _Decimal128 keywords are used to access it. Use via mode attributes is also diagnosed ("unable to emulate 'SD'"); so is use of the FLOAT_CONST_DECIMAL64 pragma. However, it is possible to access those types via typeof applied to constants or built-in functions without such an error. I expect that there are ways to get an ICE from this; certainly it uses a completely undefined ABI. This patch arranges for the types not to exist in the compiler at all when DFP is not supported. As is done with unsupported _FloatN / _FloatNx types, the global tree nodes are left as NULL_TREE, and the built-in function machinery is made to use error_mark_node for them in that case in builtin-types.def, so that the built-in functions are unavailable. Code handling constants is adjusted to give an error, and other code that might not work with the global tree nodes being NULL_TREE is also updated. Bootstrapped with no regressions for x86_64-pc-linux-gnu. Also tested with no regressions for cross to aarch64-linux-gnu, as a configuration without DFP support.

2019-11-14Support UTF-8 character constants for C2x.Joseph Myers1-1/+3
C2x adds u8'' character constants to C. This patch adds the corresponding GCC support. Most of the support was already present for C++ and just needed enabling for C2x. However, in C2x these constants have type unsigned char, which required corresponding adjustments in the compiler and the preprocessor to give them that type for C. For C, it seems clear to me that having type unsigned char means the constants are unsigned in the preprocessor (and thus treated as having type uintmax_t in #if conditionals), so this patch implements that. I included a conditional in the libcpp change to avoid affecting signedness for C++, but I'm not sure if in fact these constants should also be unsigned in the preprocessor for C++ in which case that !CPP_OPTION (pfile, cplusplus) conditional would not be needed.

2019-08-23[PATCH, c-family] Fix a PCH thinko (and thus PR61250).Iain Sandoe1-7/+0
When we are parsing a source file, the very first token might be a PRAGMA_GCC_PCH_PREPROCESS. This indicates that we are going read in a PCH file (named as the value of the pragma). If we don't see this pragma, then we know that it's OK to release any resources that the host might have set aside for the PCH file. This fixes a thinko in the current implementation, in that the decision to release resources was happening unconditionally right after the first token is extracted but before it's been checked or acted upon. This leads to the pch bug (seen on Darwin), because we actually do release resources - which are subsequently (reasonably) assumed to be available when reading a PCH file. We then get random crashes or hangs depending on the interaction between unmmap and malloc. The bug is present everywhere but doesn't show on (say) Linux, since the release of PCH resources is a NOP there. This effects all the c-family front ends, because they all use c_lex_with_flags () to implement this. The solution is to check for the PRAGMA_GCC_PCH_PREPROCESS and only call c_common_no_more_pch () when that is not the first token. A secondary effect of the collection is that the name of the PCH file can be collected during the ggc_pch_read() reset of state. Therefore we should issue any diagnostic that might name the file before the collections are triggered. gcc/c-family/ 2019-08-23 Iain Sandoe <iain@sandoe.co.uk> PR pch/61250 * c-lex.c (c_lex_with_flags): Don't call c_common_no_more_pch () from here. gcc/c/ 2019-08-23 Iain Sandoe <iain@sandoe.co.uk> PR pch/61250 * c-parser.c (c_parse_file): Call c_common_no_more_pch () after determining that the first token is not PRAGMA_GCC_PCH_PREPROCESS. gcc/cp/ 2019-08-23 Iain Sandoe <iain@sandoe.co.uk> PR pch/61250 * parser.c (cp_parser_initial_pragma): Call c_common_no_more_pch () after determining that the first token is not PRAGMA_GCC_PCH_PREPROCESS. gcc/ 2019-08-23 Iain Sandoe <iain@sandoe.co.uk> PR pch/61250 * ggc-page.c (ggc_pch_read): Read the ggc_pch_ondisk structure and issue any diagnostics needed before collecting the pre-PCH state.

2018-11-16Implement P0479R5, [[likely]] and [[unlikely]].Jason Merrill1-1/+3
[[likely]] and [[unlikely]] are equivalent to the GNU hot/cold attributes, except that they can be applied to arbitrary statements as well as labels; this is most likely to be useful for marking if/else branches as likely or unlikely. Conveniently, PREDICT_EXPR fits the bill nicely as a representation. I also had to fix marking case labels as hot/cold, which didn't work before. Which then required me to force __attribute ((fallthrough)) to apply to the statement rather than the label. gcc/ * gimplify.c (gimplify_case_label_expr): Handle hot/cold attributes. gcc/c-family/ * c-lex.c (c_common_has_attribute): Handle likely/unlikely. * c-attribs.c (attr_cold_hot_exclusions): Make public. gcc/cp/ * tree.c (handle_likeliness_attribute): New.

2017-08-24C: fix logic within c_expr::get_locationDavid Malcolm1-1/+1
In r251239 I added a c_expr::get_location method for use by c_parser_expr_list for building the vec<location_t> for an expression list, rather than using the location of the first token. When determining whether to use the location within the tree node, or fall back to the range in the c_expr, I used EXPR_CAN_HAVE_LOCATION, rather than EXPR_HAS_LOCATION. This meant that any tree nodes of kinds that *can* have a location but which erroneously had EXPR_LOCATION (value) == UNKNOWN_LOCATION had that value added to the vec<location_t>, leading to missing location information when reporting on the issue (seen with gcc.dg/Wtraditional-conversion-2.c for m68k). This patch addresses this in two ways: (a) it fixes the specific issue in this failing test case, by setting up the location properly on the EXCESS_PRECISION_EXPR. (b) updating c_expr::get_location by only using the EXPR_LOCATION if it's sane. Arguably this is papering over bugs, but they are pre-existing ones exposed by r251239, and I'd rather have this fix in place than play whack-a-mole on any other such "missing location" bugs that are lurking in the codebase. gcc/c/ChangeLog: * c-tree.h (c_expr::get_location) Use EXPR_HAS_LOCATION rather than CAN_HAVE_LOCATION_P when determining whether to use the location_t value within "value". gcc/c-family/ChangeLog: * c-lex.c (interpret_float): Use token location when building an EXCESS_PRECISION_EXPR.

2016-08-19Implement C _FloatN, _FloatNx types.Joseph Myers1-0/+31
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).
