2019-02-06Fix type of extern array declared in inner scope with outer initialization ↵Joseph Myers2-2/+13
shadowed (PR c/88584). As reported in bug 88584, if you have a file-scope array with external linkage, initialized at file scope, and that array is shadowed at block scope, and is declared again with external linkage and an incomplete type in an inner scope, it is wrongly given a complete type in that inner scope when the correct C semantics give it an incomplete type (only the visible declarations contribute to the type in a given scope). In general, issues with the types of external linkage declarations being different in different scopes were addressed by my fixes for bug 13801, for GCC 4.0. In this case, however, the code in pushdecl dealing with giving declarations the right type in each scope works fine, and the type is subsequently modified by complete_array_type called from finish_decl: finish_decl is trying to complete an array type based on an initializer, but that's only correct for the original initialization at file scope, not for such a declaration in an inner scope (it's harmless but unnecessary in the case where the original declaration is still visible in the inner scope). Thus, this patch changes finish_decl to stop this logic applying for such an external declaration in an inner scope. (An erroneous attempt to include an initializer for an extern variable in an inner scope is diagnosed elsewhere.) This is a regression from GCC 3.4, which properly rejected the code in question (quite likely by accident). Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc/c: PR c/88584 * c-decl.c (finish_decl): Do not complete array types for arrays with external linkage not at file scope. gcc/testsuite: PR c/88584 * gcc.dg/redecl-18.c: New test.

2019-01-07Fix diagnostics for never-defined inline and nested functions (PR c/88720, ↵Joseph Myers2-2/+12
PR c/88726). Bugs 88720 and 88726 report issues where a function is declared inline in an inner scope, resulting in spurious diagnostics about it being declared but never defined when that scope is left (possibly in some cases also wrongly referring to the function as a nested function). These are regressions that were introduced with the support for C99 inline semantics in 4.3 (they don't appear with 4.2; it's possible some aspects of the bugs might have been introduced later than 4.3). For the case of functions being wrongly referred to as nested, DECL_EXTERNAL was not the right condition for a function being non-nested; TREE_PUBLIC is appropriate for the case of non-nested functions with external linkage, while !b->nested means this is the outermost scope in which the function was declared and so avoids catching the case of a file-scope static being redeclared inline inside a function. For the non-nested, external-linkage case, the code attempts to avoid duplicate diagnostics by diagnosing only when scope != external_scope, but actually scope == external_scope is more appropriate, as it's only when the file and external scopes are popped that the code can actually tell whether a function ended up being defined, and all such functions will appear in the (GCC-internal) external scope. Bootstrapped with no regressions on x86_64-pc-linux-gnu.

2018-12-19C++: improvements to binary operator diagnostics (PR c++/87504)David Malcolm2-38/+11
The C frontend is able (where expression locations are available) to print problems with binary operators in 3-location form, labelling the types of the expressions: arg_0 op arg_1 ~~~~~ ^~ ~~~~~ | | | arg1 type arg0 type The C++ frontend currently just shows the combined location: arg_0 op arg_1 ~~~~~~^~~~~~~~ and fails to highlight where the subexpressions are, or their types. This patch introduces a op_location_t struct for handling the above operator-location vs combined-location split, and a new class binary_op_rich_location for displaying the above, so that the C++ frontend is able to use the more detailed 3-location form for type mismatches in binary operators, and for -Wtautological-compare (where types are not displayed). Both forms can be seen in this example: bad-binary-ops.C:69:20: error: no match for 'operator&&' (operand types are 's' and 't') 69 | return ns_4::foo && ns_4::inner::bar; | ~~~~~~~~~ ^~ ~~~~~~~~~~~~~~~~ | | | | s t bad-binary-ops.C:69:20: note: candidate: 'operator&&(bool, bool)' <built-in> 69 | return ns_4::foo && ns_4::inner::bar; | ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~ The patch also allows for some uses of macros in -Wtautological-compare, where both sides of the comparison have been spelled the same way, e.g.: Wtautological-compare-ranges.c:23:11: warning: self-comparison always evaluates to true [-Wtautological-compare] 23 | if (FOO == FOO); | ^~ gcc/c-family/ChangeLog: PR c++/87504 * c-common.h (warn_tautological_cmp): Convert 1st param from location_t to const op_location_t &. * c-warn.c (find_array_ref_with_const_idx_r): Call fold_for_warn when testing for INTEGER_CST.

2018-12-06asm qualifiers (PR55681)Segher Boessenkool2-31/+49
PR55681 observes that currently only one qualifier is allowed for inline asm, so that e.g. "volatile asm" is allowed, "const asm" is also okay (with a warning), but "const volatile asm" gives an error. Also "goto" has to be last. This patch changes things so that only "asm-qualifiers" are allowed, that is "volatile" and "goto", in any combination, in any order, but without repetitions.

2018-10-29C++: simplify output from suggest_alternatives_forDavid Malcolm3-18/+26
In the C++ FE, after emitting various errors about unrecognized names, the parser can call suggest_alternatives_for and/or suggest_alternative_in_explicit_scope. These can issue zero or more suggestions for the unrecognized name, or various other "note" diagnostics suggesting how to fix the problem. For example, currently g++ emits: t.cc:12:3: error: 'gtk_widget_showall' was not declared in this scope 12 | gtk_widget_showall (w); | ^~~~~~~~~~~~~~~~~~ t.cc:12:3: note: suggested alternative: 'gtk_widget_show_all' 12 | gtk_widget_showall (w); | ^~~~~~~~~~~~~~~~~~ | gtk_widget_show_all This patch consolidates the common case when there is a single candidate, so that the error can issue a fix-it hint directly. This simplifies the above to: t.cc:12:3: error: 'gtk_widget_showall' was not declared in this scope; did you mean 'gtk_widget_show_all'? 12 | gtk_widget_showall (w); | ^~~~~~~~~~~~~~~~~~ | gtk_widget_show_all omitting the second "note" diagnostic. Doing so requires changing the above "suggest_" functions so that rather than being called after "error" and emitting a note directly, they are called before the "error", and return a name_hint, which can contain a suggestion and/or a deferred diagnostic. The "single candidate" case is handled via a suggestion, and the "multiple candidates" case via a new subclass of deferred_diagnostic. There was some complication due to the fact that we don't always have enough location information to issue a fix-it hint. Specifically, for the case in qualified_name_lookup_error, the location is that of the name, but the location of the qualifier prefix isn't reliably available. For some hints, e.g. spell-corrections, the replacement is of the name, and for others, e.g. parent namespaces, it's for the qualified name. The patch addresses this by splitting this case out into a new "suggest_alternatives_in_other_namespaces" function, for which fix-it hints aren't issued. Another complication is that of emitting a note when --param cxx-max-namespaces-for-diagnostic-help is reached. The patch emulates the existing behavior by emitting the note from a deferred_diagnostic. This potentially needs to co-exist with another deferred_diagnostic, so it works as a decorator around any other such deferred_diagnostic. Doing so requires slightly extending class name_hint. On adding test coverage for the various cases, I discovered that after emitting a "FOO is not a namespace-name" error, we also emit a "expected namespace-name before" error. The patch removes this second error for the case where it's redundant, simplifying this case from e.g.: spellcheck-ns.C:10:24: error: 'inner_ms' is not a namespace-name 10 | using namespace outer::inner_ms; | ^~~~~~~~ spellcheck-ns.C:10:24: note: suggested alternative: 'inner_ns' 10 | using namespace outer::inner_ms; | ^~~~~~~~ | inner_ns spellcheck-ns.C:10:32: error: expected namespace-name before ';' token 10 | using namespace outer::inner_ms; | ^ to: spellcheck-ns.C:10:24: error: 'inner_ms' is not a namespace-name; did you mean 'inner_ns'? 10 | using namespace outer::inner_ms; | ^~~~~~~~ | inner_ns include/ChangeLog: * unique-ptr.h (gnu::move): Generalize so it applies to all lvalue references, rather than just to unique_ptr values. gcc/c-family/ChangeLog: * name-hint.h (name_hint::take_deferred): New member function. gcc/c/ChangeLog: * c-decl.c (implicit_decl_warning): Update "is there a suggestion" logic for change to name_hint::operator bool.

2018-10-18Add -std=c2x, -std=gnu2x, -Wc11-c2x-compat, C2X _Static_assert support.Joseph Myers4-20/+91
Now new features are starting to be added to a C2X draft (in the C2x branch of the C standard git repository, no public WG14 document yet), it's time to add -std=c2x and associated options to GCC for use in enabling C2X features. This patch adds the expected set of options: -std=c2x, -std=gnu2x, -Wc11-c2x-compat. A first C2X feature is added (the only one so far in the repository that's obviously relevant to GCC): support (as in C++) for the string constant to be omitted in _Static_assert. This feature is duly also supported as an extension in earlier standard modes (diagnosed with -pedantic, unless -Wno-c11-c2x-compat is given, or with -Wc11-c2x-compat even in C2X mode).

2018-09-26Support excess precision for integer / floating-point comparisons (PR c/87390).Joseph Myers2-0/+20
In C11, implicit conversions from integer to floating-point types produce results with the range and precision of the corresponding evaluation format rather than only those of the type implicitly converted to. This patch implements that case of C11 excess precision semantics in the case of a comparison between integer and floating-point types, previously missed when implementing other cases of excess precision for such implicit conversions. As with other such fixes, this patch conservatively follows the reading of C99 where conversions from integer to floating-point do not produce results with excess precision and so the change is made for C11 mode only. Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc/c: PR c/87390 * c-typeck.c (build_binary_op): Use excess precision for comparisons of integers and floating-point for C11 and later. gcc/testsuite: PR c/87390 * gcc.target/i386/excess-precision-9.c, gcc.target/i386/excess-precision-10.c: New tests.
