2018-01-10Preserving locations for variable-uses and constants (PR c++/43486)David Malcolm1-7/+76
This patch implements location wrapper nodes, preserving source locations of the uses of variables and constants in various places in the C++ frontend: at the arguments at callsites, and for typeid, alignof, sizeof, and offsetof. For example, it allows the C++ FE to underline the pertinent argument for mismatching calls, for such expressions, improving: extern int callee (int one, const char *two, float three); int caller (int first, int second, float third) { return callee (first, second, third); } from test.cc: In function 'int caller(int, int, float)': test.cc:5:38: error: invalid conversion from 'int' to 'const char*' [-fpermissive] return callee (first, second, third); ^ test.cc:1:41: note: initializing argument 2 of 'int callee(int, const char*, float)' extern int callee (int one, const char *two, float three); ~~~~~~~~~~~~^~~ to: test.cc: In function 'int caller(int, int, float)': test.cc:5:25: error: invalid conversion from 'int' to 'const char*' [-fpermissive] return callee (first, second, third); ^~~~~~ test.cc:1:41: note: initializing argument 2 of 'int callee(int, const char*, float)' extern int callee (int one, const char *two, float three); ~~~~~~~~~~~~^~~ This is the combination of the following patches: "[PATCH 01/14] C++: preserve locations within build_address" https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00883.html "[PATCH v2.4 of 02/14] Support for adding and stripping location_t wrapper nodes" https://gcc.gnu.org/ml/gcc-patches/2018-01/msg00591.html "[PATCH] Eliminate location wrappers in tree_nop_conversion/STRIP_NOPS" https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01330.html "[PATCH v4 of 03/14] C++: add location_t wrapper nodes during parsing (minimal impl)" https://gcc.gnu.org/ml/gcc-patches/2018-01/msg00660.html "[PATCH 04/14] Update testsuite to show improvements" https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00891.html "[v3 of 05/14] C++: handle locations wrappers when calling warn_for_memset" https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01378.html "[PATCH 07/14] reject_gcc_builtin: strip any location wrappers" https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00886.html "[v3 of PATCH 08/14] cp/tree.c: strip location wrappers in lvalue_kind" https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01433.html "[PATCH 09/14] Strip location wrappers in null_ptr_cst_p" https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00888.html "[PATCH 11/14] Handle location wrappers in string_conv_p" https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00890.html "[PATCH 12/14] C++: introduce null_node_p" https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00894.html "[v3 of PATCH 13/14] c-format.c: handle location wrappers" https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01494.html "[PATCH 14/14] pp_c_cast_expression: don't print casts for location wrappers" https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00893.html "[v3 of PATCH 15/14] Use fold_for_warn in get_atomic_generic_size" https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01380.html "[PATCH] Add selftest for "fold_for_warn (error_mark_node)"" https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01385.html gcc/c-family/ChangeLog: PR c++/43486 * c-common.c: Include "selftest.h".

This patch completes the infrastructure for the introduction of statement frontiers in C-family languages. It brings in all the code remaining code needed to introduce and transform begin stmt trees, gimple stmts, insns and notes, and ultimately use them to generate the is_stmt column in DWARF2+ line number tables/programs, however none of it is activated: the option that would do so will be introduced in a subsequent patch.

2017-10-31diagnostics: get rid of *_at_rich_loc in favor of overloadingDavid Malcolm1-3/+3
Adding a fix-it hint currently involves changing e.g.: error_at (token->location, "unknown type name %qE; did you mean %qs?", token->value, hint); to: gcc_rich_location richloc (token->location); richloc.add_fixit_replace (hint); error_at_rich_loc (&richloc, "unknown type name %qE; did you mean %qs?", token->value, hint); to make the change from taking a location_t to a rich_location *. This patch renames the "*_at_rich_loc" diagnostic entrypoints to use the same function names for rich_location * as for location_t, via overloading, to simplify the above change to just changing from: error_at (token->location, "unknown type name %qE; did you mean %qs?", token->value, hint); to: gcc_rich_location richloc (token->location); richloc.add_fixit_replace (hint); error_at (&richloc, "unknown type name %qE; did you mean %qs?", token->value, hint); thus saving space (and typing) and usually avoiding the need to reindent the "error_at" invocation. With this change, 0 is no longer acceptable as a location_t to these entrypoints, as e.g.: ../../src/gcc/auto-profile.c:855:37: error: call of overloaded 'inform(int, const char [18])' is ambiguous inform (0, "Not expected TAG."); ^ In file included from ../../src/gcc/auto-profile.c:35:0: ../../src/gcc/diagnostic-core.h:88:13: note: candidate: 'void inform(location_t, const char*, ...)' extern void inform (location_t, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3); ^~~~~~ ../../src/gcc/diagnostic-core.h:89:13: note: candidate: 'void inform(rich_location*, const char*, ...)' extern void inform (rich_location *, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3); ^~~~~~ Such locations now need to be spelled out as UNKNOWN_LOCATION, rather than 0. I considered making the API take a rich_location & rather than a rich_location *, but doing so would mean replacing diagnostic_set_info and diagnostic_set_info_translated with a constructor for diagnostic_info, which was a more invasive change.
