2022-01-11c-family: Fix up -W*conversion on bitwise &/|/^ [PR101537]Jakub Jelinek1-0/+28
The following testcases emit a bogus -Wconversion warning. This is because conversion_warning function doesn't handle BIT_*_EXPR (only unsafe_conversion_p that is called during the default: case, and that one doesn't handle SAVE_EXPRs added because the unsigned char & or | operands promoted to int have side-effects and =| or =& is used. The patch handles BIT_IOR_EXPR/BIT_XOR_EXPR like the last 2 operands of COND_EXPR by recursing on the two operands, if either of them doesn't fit into the narrower type, complain. BIT_AND_EXPR too, but first it needs to handle some special cases that unsafe_conversion_p does, namely when one of the two operands is a constant. This fixes completely the pr101537.c test and for C also pr103881.c and doesn't regress anything in the testsuite, for C++ pr103881.c still emits the bogus warnings. This is because while the C FE emits in that case a SAVE_EXPR that conversion_warning can handle already, C++ FE emits TARGET_EXPR <D.whatever, ...>, something | D.whatever etc. and conversion_warning handles COMPOUND_EXPR by "recursing" on the rhs. To handle that case, we'd need for TARGET_EXPR on the lhs remember in some hash map the mapping from D.whatever to the TARGET_EXPR and when we see D.whatever, use corresponding TARGET_EXPR initializer instead. 2022-01-11 Jakub Jelinek <jakub@redhat.com> PR c/101537 PR c/103881 gcc/c-family/ * c-warn.c (conversion_warning): Handle BIT_AND_EXPR, BIT_IOR_EXPR and BIT_XOR_EXPR. gcc/testsuite/ * c-c++-common/pr101537.c: New test. * c-c++-common/pr103881.c: New test.

This patch addresses one of my leftovers from GCC 11. C++20 introduced [depr.array.comp]: "Equality and relational comparisons between two operands of array type are deprecated." so this patch adds -Warray-compare. Since the code in question is dubious (the comparison doesn't actually compare the array elements), I've added this warning for C too, and enabled it in all C++ modes.

2021-06-08c++: remove redundant warning [PR100879]Jason Merrill1-12/+0
Before my r277864, build_new_op promoted enums to int before passing them on to cp_build_binary_op; after that commit, it doesn't, so warn_for_sign_compare sees the enum operands and gives a redundant warning. This warning dates back to 1995, and seems to have been dead code for a long time--likely since build_new_op was added in 1997--so let's just remove it.

Honza has fairly recently changed operand_equal_p to compare DECL_FIELD_OFFSET for COMPONENT_REFs when comparing addresses. As the first testcase in this patch shows, while that is very nice for optimizations, for the -Wduplicated-branches warning it causes regressions. Pedantically a union in both C and C++ has only one active member at a time, so using some other union member even if it has the same type is UB, so I think the warning shouldn't warn when it sees access to different fields that happen to have the same offset and should consider them different. In my first attempt to fix this I've keyed the old behavior on OEP_LEXICOGRAPHIC, but unfortunately that has various problems, the warning has a quick non-lexicographic compare in build_conditional_expr* and another lexicographic more expensive one later during genericization and turning the first one into lexicographic would mean wasting compile time on large conditionals. So, this patch instead introduces a new OEP_ flag and makes sure to pass it to operand_equal_p in all -Wduplicated-branches cases. The cvt.c changes are because on the other testcase we were warning with UNKNOWN_LOCATION, so the user wouldn't really know where the questionable code is. 2021-03-25 Jakub Jelinek <jakub@redhat.com> PR c++/99565 * tree-core.h (enum operand_equal_flag): Add OEP_ADDRESS_OF_SAME_FIELD. * fold-const.c (operand_compare::operand_equal_p): Don't compare field offsets if OEP_ADDRESS_OF_SAME_FIELD. * c-warn.c (do_warn_duplicated_branches): Pass also OEP_ADDRESS_OF_SAME_FIELD to operand_equal_p. * c-typeck.c (build_conditional_expr): Pass OEP_ADDRESS_OF_SAME_FIELD to operand_equal_p. * call.c (build_conditional_expr_1): Pass OEP_ADDRESS_OF_SAME_FIELD to operand_equal_p. * cvt.c (convert_to_void): Preserve location_t on COND_EXPR or or COMPOUND_EXPR. * g++.dg/warn/Wduplicated-branches6.C: New test. * g++.dg/warn/Wduplicated-branches7.C: New test.

2020-11-10c, c++: Fix up -Wunused-value on COMPLEX_EXPRs [PR97748]Jakub Jelinek1-2/+11
The -Wunused-value warning in both C and C++ FEs (implemented significantly differently between the two) sees the COMPLEX_EXPRs created e.g. for complex pre/post increment and many other expressions as useless and warns about it. For the C warning implementation, on e.g. COMPLEX_EXPR < ++REALPART_EXPR <x>, IMAGPART_EXPR <x>>; would warn even on the IMAGPART_EXPR <x> there alone etc., so what works is check if we'd warn about both operands of COMPLEX_EXPR and if yes, warn on the whole COMPLEX_EXPR, otherwise don't warn. The C++ warning implementation is significantly different and for that one the only warn if both would be warned about doesn't really work, we then miss warnings e.g. about COMPLEX_EXPR <REALPART_EXPR <SAVE_EXPR <x>> + 1.0e+0, IMAGPART_EXPR <SAVE_EXPR <x>>> >>>>> The patch replaces the warning_at call with call to the c-family warn_if_unused_value function. On the testcase which after the initial new tests contains pretty much everything from gcc.dg/Wunused-value-1.c both approaches seem to work nicely. 2020-11-10 Jakub Jelinek <jakub@redhat.com> PR c/97748 gcc/c-family/ * c-common.h (warn_if_unused_value): Add quiet argument defaulted to false. * c-warn.c (warn_if_unused_value): Likewise.

2020-10-23c, c++: Implement -Wsizeof-array-div [PR91741]Marek Polacek1-0/+47
This patch implements a new warning, -Wsizeof-array-div. It warns about code like int arr[10]; sizeof (arr) / sizeof (short); where we have a division of two sizeof expressions, where the first argument is an array, and the second sizeof does not equal the size of the array element. See e.g. <https://www.viva64.com/en/examples/v706/>. Clang makes it possible to suppress the warning by parenthesizing the second sizeof like this: sizeof (arr) / (sizeof (short)); so I followed suit. In the C++ FE this was rather easy, because finish_parenthesized_expr already set TREE_NO_WARNING. In the C FE I've added a new tree code, PAREN_SIZEOF_EXPR, to discern between the non-() and () versions. This warning is enabled by -Wall. An example of the output: x.c:5:23: warning: expression does not compute the number of elements in this array; element type is ‘int’, not ‘short int’ [-Wsizeof-array-div] 5 | return sizeof (arr) / sizeof (short); | ~~~~~~~~~~~~~^~~~~~~~~~~~~~~~ x.c:5:25: note: add parentheses around ‘sizeof (short int)’ to silence this warning 5 | return sizeof (arr) / sizeof (short); | ^~~~~~~~~~~~~~ | ( ) x.c:4:7: note: array ‘arr’ declared here 4 | int arr[10]; | ^~~ gcc/c-family/ChangeLog: PR c++/91741 * c-common.c (verify_tree): Handle PAREN_SIZEOF_EXPR.

2020-03-23c++: Handle COMPOUND_EXPRs in get_narrower and ↵Jakub Jelinek1-0/+5
warnings_for_convert_and_check [PR91993] As the testcases shows, the -Wconversion warning behaves quite differently when -fsanitize=undefined vs. when not sanitizing, but in the end it is not something specific to sanitizing, if a user uses return static_cast<uc>(static_cast<uc>((d++, a) << 1U) | b) | c; instead of return static_cast<uc>(static_cast<uc>(a << 1U) | b) | c; and thus there is some COMPOUND_EXPR involved, cp_build_binary_op behaves significantly different, e.g. shorten_binary_op will have different result (uc for the case without COMPOUND_EXPR, int with it), but it isn't limited to that. > How about improving get_narrower to handle COMPOUND_EXPR? I'd think that > would do the trick without affecting evaluation order. Not completely, had to change also warnings_for_convert_and_check, but with that it works. The float-cast-overflow* changes are needed because now with -O1+ we emit lots of -Woverflow warnings on the testcase, but we do emit those warnings on the testcase even when compiling just with -O1 and without -fsanitize=float-cast-overflow, so it seems to me a change in the right direction, having -fsanitize= or explicit comma expressions smaller effect on the warnings that are emitted. 2020-03-23 Jakub Jelinek <jakub@redhat.com> PR c++/91993 * tree.c (get_narrower): Handle COMPOUND_EXPR by recursing on ultimate rhs and if returned something different, reconstructing the COMPOUND_EXPRs. * c-warn.c (warnings_for_convert_and_check): For expr and/or result being COMPOUND_EXPRs, skip to ultimate rhs. * g++.dg/warn/Wconversion-pr91993.C: New test. * g++.dg/ubsan/pr91993.C: New test. * c-c++-common/ubsan/float-cast-overflow-1.c: Add -Wno-overflow to dg-options. * c-c++-common/ubsan/float-cast-overflow-2.c: Likewise. * c-c++-common/ubsan/float-cast-overflow-4.c: Likewise.

Also, to fix the PR 40752 testcases on -funsigned-char targets, don't consider -Wsign-conversion for the second operand of PLUS_EXPR, especially since fold changes "x - 5" to "x + (-5)".

2019-04-26Fix use of COMPLETE_TYPE_P for -Wstrict-aliasing=1Richard Sandiford1-1/+1
The handling of -Wstrict-aliasing=1 applied COMPLETE_TYPE_P to the pointer type rather than the pointer target, so missed the warnings for "struct incomplete" in the testcase. I couldn't find any existing C tests for -Wstrict-aliasing=1, so I added a few extra tests besides the ones fixed by the patch. I'm sure there's lots more we could test -- this is just supposed to be better than the status quo (i.e. nothing). 2019-04-26 Richard Sandiford <richard.sandiford@arm.com> gcc/c-family/ * c-warn.c (strict_aliasing_warning): Apply COMPLETE_TYPE_P to the pointer target rather than the pointer itself. gcc/testsuite/ * gcc.dg/alias-16.c: New test.

2018-12-19C++: improvements to binary operator diagnostics (PR c++/87504)David Malcolm1-10/+47
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.

2018-12-19C++: more location wrapper nodes (PR c++/43064, PR c++/43486)David Malcolm1-27/+44
This is v6 of the patch, as posted to: https://gcc.gnu.org/ml/gcc-patches/2018-12/msg01331.html The C++ frontend gained various location wrapper nodes in r256448 (GCC 8). That patch: https://gcc.gnu.org/ml/gcc-patches/2018-01/msg00799.html added wrapper nodes around all nodes with !CAN_HAVE_LOCATION_P for: * arguments at callsites, and for * typeid, alignof, sizeof, and offsetof. This is a followup to that patch, adding many more location wrappers to the C++ frontend. It adds location wrappers for nodes with !CAN_HAVE_LOCATION_P to: * all literal nodes (in cp_parser_primary_expression) * all id-expression nodes (in finish_id_expression), except within a decltype. * all mem-initializer nodes within a mem-initializer-list (in cp_parser_mem_initializer) However, the patch also adds some suppressions: regions in the parser for which wrapper nodes will not be created: * within a template-parameter-list or template-argument-list (in cp_parser_template_parameter_list and cp_parser_template_argument_list respectively), to avoid encoding the spelling location of the nodes in types. For example, "array<10>" and "array<10>" are the same type, despite the fact that the two different "10" tokens are spelled in different locations in the source. * within a gnu-style attribute (none of are handlers are set up to cope with location wrappers yet) * within various OpenMP clauses The patch enables various improvements to locations for bad initializations, for -Wchar-subscripts, and enables various other improvements in the followup patch. For example, given the followup buggy mem-initializer: class X { X() : bad(42), good(42) { } void* bad; int good; }; previously, our diagnostic was on the final close parenthesis of the mem-initializer-list, leaving it unclear where the problem is: t.cc: In constructor 'X::X()': t.cc:3:16: error: invalid conversion from 'int' to 'void*' [-fpermissive] 3 | good(42) | ^ | | | int whereas with the patch we highlight which expression is bogus: t.cc: In constructor 'X::X()': t.cc:2:13: error: invalid conversion from 'int' to 'void*' [-fpermissive] 2 | X() : bad(42), | ^~ | | | int Similarly, the diagnostic for this bogus initialization: i.cc:1:44: error: initializer-string for array of chars is too long [-fpermissive] 1 | char test[3][4] = { "ok", "too long", "ok" }; | ^ is improved by the patch so that it indicates which string is too long: i.cc:1:27: error: initializer-string for array of chars is too long [-fpermissive] 1 | char test[3][4] = { "ok", "too long", "ok" }; | ^~~~~~~~~~ gcc/c-family/ChangeLog: PR c++/43064 PR c++/43486 * c-common.c (unsafe_conversion_p): Fold any location wrapper.
