2018-08-20Add support for grouping of related diagnostics (PR other/84889)David Malcolm
We often emit logically-related groups of diagnostics. A relatively simple case is this: if (warning_at (body_loc, OPT_Wmultistatement_macros, "macro expands to multiple statements")) inform (guard_loc, "some parts of macro expansion are not guarded by " "this %qs clause", guard_tinfo_to_string (keyword)); where the "note" diagnostic issued by the "inform" call is guarded by the -Wmultistatement_macros warning. More complicated examples can be seen in the C++ frontend, where e.g. print_z_candidates can lead to numerous "note" diagnostics being emitted. I'm looking at various ways to improve how we handle such related diagnostics, but, prior to this patch, there was no explicit relationship between these diagnostics: the diagnostics subsystem had no way of "knowing" that these were related. This patch introduces a simple way to group the diagnostics: an auto_diagnostic_group class: all diagnostics emitted within the lifetime of an auto_diagnostic_group instance are logically grouped. Hence in the above example, the two diagnostics can be grouped by simply adding an auto_diagnostic_group instance: auto_diagnostic_group d; if (warning_at (body_loc, OPT_Wmultistatement_macros, "macro expands to multiple statements")) inform (guard_loc, "some parts of macro expansion are not guarded by " "this %qs clause", guard_tinfo_to_string (keyword)); Some more awkard cases are of the form: if (some_condition && warning_at (...) && more_conditions) inform (...); which thus need restructuring to: if (some_condition) { auto_diagnostic_group d; warning_at (...); if (more_conditions) inform (...); } so that the lifetime of the auto_diagnostic_group groups the warning_at and the inform call. Nesting is handled by simply tracking a nesting depth within the diagnostic_context.: all diagnostics are treated as grouped until the final auto_diagnostic_group is popped. diagnostic.c uses this internally, so that all diagnostics are part of a group - those that are "by themselves" are treated as being part of a group with one element. The diagnostic_context gains optional callbacks for displaying the start of a group (when the first diagnostic is emitted within it), and the end of a group (for when the group was non-empty); these callbacks are unused by default, but a test plugin demonstrates them (and verifies that the machinery is working). As noted above, I'm looking at various ways to use the grouping to improve how we output the diagnostics. FWIW, I experimented with a more involved implementation, of the form: diagnostic_group d; if (d.warning_at (body_loc, OPT_Wmultistatement_macros, "macro expands to multiple statements")) d.inform (guard_loc, "some parts of macro expansion are not guarded by " "this %qs clause", guard_tinfo_to_string (keyword)); which had the advantage of allowing auto-detection of the places where groups were needed (by converting ::warning_at's return type to bool), but it was a much more invasive patch, especially when dealing with the places in the C++ frontend that can emit numerous notes after an error or warning (and thus having to pass the group around) Hence I went with this simpler approach. gcc/c-family/ChangeLog: PR other/84889 * c-attribs.c (common_handle_aligned_attribute): Add auto_diagnostic_group instance. * c-indentation.c (warn_for_misleading_indentation): Likewise. * c-opts.c (c_common_post_options): Likewise. * c-warn.c (warn_logical_not_parentheses): Likewise.

2017-09-21enable handling of -gno- command-line options as negated prefixesAlexandre Oliva
This patch that adds -g to the set of negatable prefixes along with -f, -m and -W. Besides the mapping from -gno- to negated -g in option_map and adding g to the [fmW] matches for negatable options, I had to introduce gno- as an remapping prefix, for the option searching machinery to backtrack to and recognize as a remapping prefix, instead of backtracking to -g and stopping at it as if no-* was its Joined argument. Adding such remapping prefixes to preempt further backtracking can be accomplished by introducing the prefix as an Undocumented option with a Joined argument and without Driver, Target, Common, or any language-specific option. Whenever we match such a fake options prefix, we abandon further backtracking (it matches, after all), but find_opt returns the same code it would if it hadn't found any match, so that we resort to option mapping. I've arranged for such remapping prefixes to not be considered when looking for and suggesting a correct spelling for misspelled options. While testing that, I found a few -W-started options that were not marked as RejectNegative but should (-Wno-a, is not something we'd like to suggest ;-) I've also marked as such -g-started options that it makes no sense to negate, and removed the explicit -gno- ones, allowing their opposites to be negated. for gcc/ChangeLog * common.opt (Wa, Wl, Wp, g, gz=): Add RejectNegative.

2012-11-17This patch rewrites the old VEC macro-based interface into a new one based ↵Diego Novillo
on the template class 'vec'. This patch rewrites the old VEC macro-based interface into a new one based on the template class 'vec'. The user-visible changes are described in http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec. I have tested the patch pretty extensively: - Regular bootstraps on x86_64, ppc, ia64, sparc and hppa. - Bootstraps with --enable-checking=release - Bootstraps with --enable-checking=gc,gcac - Basic builds on all targets (using contrib/config-list.mk). We no longer access the vectors via VEC_* macros. The pattern is "VEC_operation (T, A, V, args)" becomes "V.operation (args)". The only thing I could not do is create proper ctors and dtors for the vec class. Since these vectors are stored in unions, we have to keep them as PODs (C++03 does not allow non-PODs in unions). This means that creation and destruction must be explicit. There is a new method vec<type, allocation, layout>::create() and another vec<type, allocation, layout>::destroy() to allocate the internal vector. For vectors that must be pointers, there is a family of free functions that implement the operations that need to tolerate NULL vectors. These functions all start with the prefix 'vec_safe_'. See the wiki page for details. The gengtype change removes the special handling for VEC() that used to exist in gengtype. Additionally, it allows gengtype to recognize templates of more than one argument and introduces the concept of an undefined type (useful for template arguments that may or may not be types). When a TYPE_UNDEFINED is reached, gengtype will ignore it if it happens inside a type marked with GTY((user)). Otherwise, it will emit an error. Finally, gengtype rejects root types marked GTY((user)) that are not first class pointers. 2012-11-16 Diego Novillo <dnovillo@google.com> VEC API overhaul (http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec) * vec.c (register_overhead): Convert it into member function of vec_prefix.

2012-09-10Remove unnecessary VEC function overloads.Diego Novillo
Several VEC member functions that accept an element 'T' used to have two overloads: one taking 'T', the second taking 'T *'. This used to be needed because of the interface dichotomy between vectors of objects and vectors of pointers. In the past, vectors of pointers would use pass-by-value semantics, but vectors of objects would use pass-by-reference semantics. This is no longer necessary, but the distinction had remained. The main side-effect of this change is some code reduction in code that manipulates vectors of objects. For instance, - struct iterator_use *iuse; - - iuse = VEC_safe_push (iterator_use, heap, iterator_uses, NULL); - iuse->iterator = iterator; - iuse->ptr = ptr; + struct iterator_use iuse = {iterator, ptr}; + VEC_safe_push (iterator_use, heap, iterator_uses, iuse); Compile time performance was not affected. Tested on x86_64 and ppc64. Also built all-gcc on all targets using VEC routines: arm, bfin, c6x, epiphany, ia64, mips, sh, spu, and vms. 2012-09-10 Diego Novillo <dnovillo@google.com> * vec.h (vec_t::quick_push): Remove overload that accepts 'T *'.
