2024-10-23diagnostics: implement buffering for non-textual formats [PR105916]David Malcolm1-11/+113
PR fortran/105916 reports stray diagnostics appearing in JSON and SARIF output from gfortran. In order to handle various awkard parsing issues, the Fortran frontend implements buffering of diagnostics, so that diagnostics reported to global_dc can be either: (a) immediately issued, or (b) speculatively reported to global_dc, and stored in a buffer, to either be issued later or discarded. This buffering code in gcc/fortran/error.cc directly manipulates implementation details of the diagnostic_context such as the pretty_printer's buffer, and the counts of how many diagnostics have been issued. The issue is that this manipulation of pretty_printer's buffer doesn't work for formats such as JSON and SARIF where diagnostics are handled in a different way (such as by accumulating json::object instances in an array). This patch moves responsibility for such buffering of diagnostics from fortran's error.cc to the diagnostic subsystem. It introduces a new class diagnostic_buffer representing a particular buffer of diagnostics that have been reported but not yet issued. Each diagnostic output format implements buffering in a different way, and so there is a new class hierarchy, diagnostic_per_format_buffer, representing the various format-specific ways that buffering is to be implemented. This is hidden as an implementation detail of diagnostic_buffer. The patch also updates how diagnostics of each kind (e.g. warnings vs errors) are counted, so that if buffering is enabled, the count is incremented within the buffer, and the counts in the diagnostic_context are only updated if and when the buffer is flushed; checking for max_errors is similarly updated to support both buffered and unbuffered cases. For ease of debugging, the patch extends the "dump" functions within the diagnostics subsystem, so that e.g. global_dc->dump () now prints the buffering status, e.g.: (gdb) call global_dc->dump() diagnostic_context: counts: (none) output format: sarif_output_format printer: m_show_color: false m_url_format: bel m_buffer: m_formatted_obstack current object: length 0: m_chunk_obstack current object: length 0: diagnostic buffer: m_per_format_buffer: counts: error: 1 diagnostic_sarif_format_buffer: result[0]: {"ruleId": "error", "level": "error", "message": {"text": "Function ‘program’ requires an argument list at (1)"}, "locations": [{"physicalLocation": {"artifactLocation": {"uri": "../../src/gcc/testsuite/gfortran.dg/pr105954.f90", "uriBaseId": "PWD"}, "region": {"startLine": 6, "startColumn": 8, "endColumn": 9}, "contextRegion": {"startLine": 6, "snippet": {"text": "program p\n"}}}}]} which shows that no diagnostics have been issued yet, but the active diagnostic_buffer has a single error buffered within it, in SARIF form. Similarly, it's possible to use "dump" on a diagnostic_buffer to directly query its contents; here's the same example, this time with the text output format: (gdb) call error_buffer.buffer.dump() m_per_format_buffer: counts: error: 1 diagnostic_text_format_buffer: m_formatted_obstack current object: length 232: 00000000: 1b 5b 30 31 6d 1b 5b 4b 2e 2e 2f 2e 2e 2f 73 72 | .[01m.[K../../sr 00000010: 63 2f 67 63 63 2f 74 65 73 74 73 75 69 74 65 2f | c/gcc/testsuite/ 00000020: 67 66 6f 72 74 72 61 6e 2e 64 67 2f 70 72 31 30 | gfortran.dg/pr10 00000030: 35 39 35 34 2e 66 39 30 3a 36 3a 38 3a 1b 5b 6d | 5954.f90:6:8:.[m 00000040: 1b 5b 4b 0a 0a 20 20 20 20 36 20 7c 20 70 72 6f | .[K.. 6 | pro 00000050: 67 72 61 6d 20 70 0a 20 20 20 20 20 20 7c 20 20 | gram p. | 00000060: 20 20 20 20 20 20 1b 5b 30 31 3b 33 31 6d 1b 5b | .[01;31m.[ 00000070: 4b 31 1b 5b 6d 1b 5b 4b 0a 1b 5b 30 31 3b 33 31 | K1.[m.[K..[01;31 00000080: 6d 1b 5b 4b 45 72 72 6f 72 3a 1b 5b 6d 1b 5b 4b | m.[KError:.[m.[K 00000090: 20 46 75 6e 63 74 69 6f 6e 20 e2 80 98 1b 5b 30 | Function ....[0 000000a0: 31 6d 1b 5b 4b 70 72 6f 67 72 61 6d 1b 5b 6d 1b | 1m.[Kprogram.[m. 000000b0: 5b 4b e2 80 99 20 72 65 71 75 69 72 65 73 20 61 | [K... requires a 000000c0: 6e 20 61 72 67 75 6d 65 6e 74 20 6c 69 73 74 20 | n argument list 000000d0: 61 74 20 1b 5b 30 31 3b 33 31 6d 1b 5b 4b 28 31 | at .[01;31m.[K(1 000000e0: 29 1b 5b 6d 1b 5b 4b 0a | ).[m.[K. m_chunk_obstack current object: length 0: showing that we have an error in error_buffer, with colorized text. gcc/ChangeLog: PR fortran/105916 * diagnostic-buffer.h: New file. * diagnostic-format-json.cc: Define INCLUDE_VECTOR.

2024-10-18diagnostics: add debug dump functionsDavid Malcolm1-0/+6
This commit expands on r15-3973-g4c7a58ac2617e2, which added debug "dump" member functiosn to pretty_printer and output_buffer. This followup adds "dump" member functions to diagnostic_context and diagnostic_format, extends the existing dump functions and adds indentation to make it much easier to see the various relationships between context, format, printer, etc. Hence you can now do: (gdb) call global_dc->dump () and get a useful summary of what the diagnostic subsystem is doing; for example: (gdb) call global_dc->dump() diagnostic_context: counts: output format: sarif_output_format printer: m_show_color: false m_url_format: bel m_buffer: m_formatted_obstack current object: length 0: m_chunk_obstack current object: length 0: pp_formatted_chunks: depth 0 0: TEXT("Function ")] 1: BEGIN_QUOTE, TEXT("program"), END_QUOTE] 2: TEXT(" requires an argument list at ")] 3: TEXT("(1)")] showing the counts of all diagnostic kind that are non-zero (none yet), that we have a sarif output format, and the printer is part-way through formatting a string. gcc/ChangeLog: * diagnostic-format-json.cc (json_output_format::dump): New. * diagnostic-format-sarif.cc (sarif_output_format::dump): New.

2024-10-16diagnostics: capture backtraces in SARIF notifications [PR116602]David Malcolm2-0/+14
This patch makes the SARIF output's crash handler attempt to capture a backtrace in JSON form within the notification's property bag. The precise format of the property is subject to change, but, for example, in one of the test cases I got output like this: "properties": {"gcc/backtrace": {"frames": [{"pc": "0x7f39c610a32d", "function": "pass_crash_test::execute(function*)", "filename": "/home/david/gcc-newgit/src/gcc/testsuite/gcc.dg/plugin/crash_test_plugin.c", "lineno": 98}]}}}], The backtrace code is based on that in diagnostic.cc. gcc/ChangeLog: PR other/116602 * diagnostic-format-sarif.cc: Include "demangle.h" and "backtrace.h".

2024-10-16testsuite: Prepare for -std=gnu23 defaultJoseph Myers1-1/+1
Now that C23 support is essentially feature-complete, I'd like to switch the default language version for C compilation to -std=gnu23. This requires updating a large number of testcases that fail with the new language version if left unchanged. In this patch, update most of the tests for which there is a safe change that works both before and after the update to default language version - typically adding the option -std=gnu17 or -Wno-old-style-definition to the tests. (There are also a few tests where I'd like to investigate further why they fail with -std=gnu23, or where I think such failures show an actual bug to fix before changing the default language version, or where it seems more appropriate to make a testcase change that would result in failures in the absence of the language version change rather than just adding an option that does nothing with the gnu17 default.) The libffi test fixes have also been submitted upstream: <https://github.com/libffi/libffi/pull/861>. Most of the failures requiring such changes are for one of two reasons: * Unprototyped function declarations with () (meaning the same as (void) in C23 mode) for a function then called with arguments. * Old-style function definitions, which warn by default in C23 mode, so resulting in test failures for the unexpected warnings. Other reasons for failures include: * Tests with their own definitions of bool, true and false. * Tests of diagnostics (often with -pedantic) in cases where C23 has changed semantics, such as: - tag compatibility for structs; - enum values out of range of int; - handing of qualified array types; - decimal floating types formerly needing -pedantic diagnostics, but being standard in C23.

2024-10-02diagnostics: support SARIF 2.2 output, undocumented for now [PR116301]David Malcolm6-0/+164
GCC currently supports outputting SARIF v2.1.0 Version 2.2 of the SARIF spec is not yet official, but the draft has already gained features we might might want to use. This patch extends the SARIF output code to accept a enum sarif_version parameter internally, representing 2.1.0 or a prerelease of 2.2 The patch updates the SARIF output selftests so that they are run for all such versions. I hope to expose this "properly" via the mechanism described in comment #13 of PR116613. In the meantime, the patch adds a new -fdiagnostics-format=sarif-file-2.2-prerelease for use by the DejaGnu testsuite, deliberately left undocumented for now. The copy of the 2.2 draft schema in the testsuite was downloaded from https://raw.githubusercontent.com/oasis-tcs/sarif-spec/refs/tags/2.2-prerelease-2024-08-08/sarif-2.2/schema/sarif-2-2.schema.json The patch adds support for capturing related locations within an ICE notification for SARIF 2.2 onwards, thus capturing "include chain" information for SARIF-based reports of ICEs that occur within a header; see https://github.com/oasis-tcs/sarif-spec/issues/540 The patch does *not* add support for the "scannedFile" role, leaving it to followup work; see https://github.com/oasis-tcs/sarif-spec/issues/459 gcc/ChangeLog: PR other/116301 * common.opt (sarif-file-2.2-prerelease): New value for -fdiagnostics-format=. * diagnostic-format-sarif.cc (sarif_location_manager::sarif_location_manager): Move initialization of m_related_locations_arr here from sarif_result's ctor.

2024-09-30diagnostics: isolate diagnostic_context with interface classes [PR116613]David Malcolm1-4/+5
As work towards supporting multiple diagnostic outputs (where each output has its own pretty_printer), avoid passing around diagnostic_context to the various printing routines, so that we can be more explicit about which pretty_printer is in use. Introduce a set of "policy" classes that capture the parts of diagnostic_context that are needed, and use these rather than diagnostic_context *. Pass around pretty_printer & rather than taking value from context. Split out the pretty_printer-using code from class layout into a new class layout_printer, separating the responsibilities of determining layout when quoting source versus actually printing the source.

The diagnostic_starter and diagnostic_finalizer callbacks and most of their support subroutines are only used by the "text" output format.

2024-08-26testsuite: generalize support for Python tests for SARIF outputDavid Malcolm5-15/+187
In r15-2354-g4d1f71d49e396c I added the ability to use Python to write tests of SARIF output via a new "run-sarif-pytest" based on "run-gcov-pytest", with a sarif.py support script in testsuite/gcc.dg/sarif-output. This followup patch: (a) removes the limitation of such tests needing to be in testsuite/gcc.dg/sarif-output by moving sarif.py to testsuite/lib and adding logic to add that directory to PYTHONPATH when invoking pytest. (b) uses this to replace fragile regexp-based tests in gcc.dg/plugin/diagnostic-test-paths-multithreaded-sarif.c with Python logic that verifies the structure within the generated JSON, and to add test coverage for SARIF output relating to GCC plugins. gcc/ChangeLog: * diagnostic-format-sarif.cc: Add comments noting that we don't yet capture any diagnostic_metadata::rules associated with a diagnostic. gcc/testsuite/ChangeLog: * gcc.dg/plugin/diagnostic-test-metadata-sarif.c: New test, based on diagnostic-test-metadata.c. * gcc.dg/plugin/diagnostic-test-metadata-sarif.py: New script. * gcc.dg/plugin/diagnostic-test-paths-multithreaded-sarif.c: Replace scan-sarif-file directives with run-sarif-pytest, to run... * gcc.dg/plugin/diagnostic-test-paths-multithreaded-sarif.py: ...this new test. * gcc.dg/plugin/plugin.exp (plugin_test_list): Add diagnostic-test-metadata-sarif.c. * gcc.dg/sarif-output/sarif.py: Move to... * lib/sarif.py: ...here. * lib/scansarif.exp (run-sarif-pytest): Prepend "lib" to PYTHONPATH before running python scripts.

2024-07-24diagnostics: SARIF output: potentially add escaped renderings of source ↵David Malcolm1-0/+1
(§3.3.4) This patch adds support to our SARIF output for cases where rich_loc.escape_on_output_p () is true, such as for -Wbidi-chars. In such cases, the pertinent SARIF "location" object gains a property bag with property "gcc/escapeNonAscii": true, and the "artifactContent" within the location's physical location's snippet" gains a "rendered" property (§3.3.4) that escapes non-ASCII text in the snippet, such as: "rendered": {"text": where "text" has a string value such as (for a "trojan source" attack): "9 | /*<U+202E> } <U+2066>if (isAdmin)<U+2069> <U+2066> begin admins only */\n" " | ~~~~~~~~ ~~~~~~~~ ^\n" " | | | |\n" " | | | end of bidirectional context\n" " | U+202E (RIGHT-TO-LEFT OVERRIDE) U+2066 (LEFT-TO-RIGHT ISOLATE)\n" where the escaping is affected by -fdiagnostics-escape-format=; with -fdiagnostics-escape-format=bytes, the rendered text of the above is: "9 | /*<e2><80><ae> } <e2><81><a6>if (isAdmin)<e2><81><a9> <e2><81><a6> begin admins only */\n" " | ~~~~~~~~~~~~ ~~~~~~~~~~~~ ^\n" " | | | |\n" " | U+202E (RIGHT-TO-LEFT OVERRIDE) U+2066 (LEFT-TO-RIGHT ISOLATE) end of bidirectional context\n" The patch also refactors/adds enough selftest machinery to be able to test the snippet generation from within the selftest framework, rather than just within DejaGnu (where the regex-based testing isn't sophisticated enough to verify such properties as the above). gcc/ChangeLog: * Makefile.in (OBJS-libcommon): Add selftest-json.o. * diagnostic-format-sarif.cc: Include "selftest.h", "selftest-diagnostic.h", "selftest-diagnostic-show-locus.h", "selftest-json.h", and "text-range-label.h".

2024-07-13diagnostics: add highlight-a vs highlight-b in colorization and pp_markupDavid Malcolm1-1/+1
Since r6-4582-g8a64515099e645 (which added class rich_location), ranges of quoted source code have been colorized using the following rules: - the primary range used the same color of the kind of the diagnostic i.e. "error" vs "warning" etc (defaulting to bold red and bold magenta respectively) - secondary ranges alternate between "range1" and "range2" (defaulting to green and blue respectively) This works for cases with large numbers of highlighted ranges, but is suboptimal for common cases. The following patch adds a pair of color names: "highlight-a" and "highlight-b", and uses them whenever it makes sense to highlight and contrast two different things in the source code (e.g. a type mismatch). These are used by diagnostic-show-locus.cc for highlighting quoted source. In addition the patch adds colorization to fragments within the corresponding diagnostic messages themselves, using consistent colorization between the message and the quoted source code for the two different things being contrasted. For example, consider: demo.c: In function ‘test_bad_format_string_args’: ../../src/demo.c:25:18: warning: format ‘%i’ expects argument of type ‘int’, but argument 2 has type ‘const char *’ [-Wformat=] 25 | printf("hello %i", msg); | ~^ ~~~ | | | | int const char * | %s Previously, the types within the message in quotes would be in bold but not colorized, and the labelled ranges of quoted source code would use bold magenta for the "int" and non-bold green for the "const char *". With this patch: - the "%i" and "int" in the message and the "int" in the quoted source are all colored bold green - the "const char *" in the message and in the quoted source are both colored bold blue so that the consistent use of contrasting color draws the reader's eyes to the relationships between the diagnostic message and the source. I've tried this with gnome-terminal with many themes, including a variety of light versus dark backgrounds, solarized versus non-solarized themes, etc, and it was readable in all. My initial version of the patch used the existing %r and %R facilities within pretty-print.cc for the messages, but this turned out to be very uncomfortable, leading to error-prone format strings such as: error_at (richloc, "invalid operands to binary %s (have %<%r%T%R%> and %<%r%T%R%>)", opname, "highlight-a", type0, "highlight-b", type1); To avoid requiring monstrosities such as the above, the patch adds a new "%e" format code to pretty-print.cc, which expects a pp_element *, where pp_element is a new abstract base class (actually a pp_markup::element), along with various useful subclasses. This lets the above be written as: pp_markup::element_quoted_type element_0 (type0, highlight_colors::lhs); pp_markup::element_quoted_type element_1 (type1, highlight_colors::rhs); error_at (richloc, "invalid operands to binary %s (have %e and %e)", opname, &element_0, &element_1); which I feel is maintainable and clear to translators; the use of %e and pp_element * captures the type-unsafe part of the variadic call, and the subclasses allow for type-safety (so e.g. an element_quoted_type expects a type and a highlighting color). This approach allows for some nice simplifications within c-format.cc. The patch also extends -Wformat to "teach" it about the new %e and pp_element *. Doing so requires c-format.cc to be able to determine if a T * is a pp_element * (i.e. if T is a subclass). To do so I added a new comp_types callback for comparing types, where the C++ frontend supplies a suitable implementation (and %e will always be wrong for C). I've manually tested this on many diagnostics with both C and C++ and it seems a subtle but significant improvement in readability. I've added a new option -fno-diagnostics-show-highlight-colors in case people prefer the old behavior. gcc/c-family/ChangeLog: * c-common.cc: Include "tree-pretty-print-markup.h". (binary_op_error): Use pp_markup::element_quoted_type and %e.

2024-05-30Add new text_art::tree_widget and use it in analyzerDavid Malcolm4-0/+4
This patch adds a new text_art::tree_widget, which makes it easy to generate hierarchical visualizations using either ASCII: +- Child 0 | +- Grandchild 0 0 | +- Grandchild 0 1 | `- Grandchild 0 2 +- Child 1 | +- Grandchild 1 0 | +- Grandchild 1 1 | `- Grandchild 1 2 `- Child 2 +- Grandchild 2 0 +- Grandchild 2 1 `- Grandchild 2 2 or Unicode: Root ├─ Child 0 │ ├─ Grandchild 0 0 │ ├─ Grandchild 0 1 │ ╰─ Grandchild 0 2 ├─ Child 1 │ ├─ Grandchild 1 0 │ ├─ Grandchild 1 1 │ ╰─ Grandchild 1 2 ╰─ Child 2 ├─ Grandchild 2 0 ├─ Grandchild 2 1 ╰─ Grandchild 2 2 potentially with colorization of the connecting lines. It adds a new template for typename T: void text_art::dump<T> (const T&); for using this to dump any object to stderr that supports a make_dump_widget method, with similar templates for dumping to a pretty_printer * and a FILE *. It uses this within the analyzer to add two new families of dumping methods: one for program states, e.g.: (gdb) call state->dump() State ├─ Region Model │ ├─ Current Frame: frame: ‘calls_malloc’@2 │ ├─ Store │ │ ├─ m_called_unknown_fn: false │ │ ├─ frame: ‘test’@1 │ │ │ ╰─ _1: (INIT_VAL(n_2(D))*(size_t)4) │ │ ╰─ frame: ‘calls_malloc’@2 │ │ ├─ result_4: &HEAP_ALLOCATED_REGION(27) │ │ ╰─ _5: &HEAP_ALLOCATED_REGION(27) │ ╰─ Dynamic Extents │ ╰─ HEAP_ALLOCATED_REGION(27): (INIT_VAL(n_2(D))*(size_t)4) ╰─ ‘malloc’ state machine ╰─ 0x468cb40: &HEAP_ALLOCATED_REGION(27): unchecked ({free}) (‘result_4’) and the other for showing the detail of the recursive makeup of svalues and regions, e.g. the (INIT_VAL(n_2(D))*(size_t)4) from above: (gdb) call size_in_bytes->dump() (17): ‘long unsigned int’: binop_svalue(mult_expr: ‘*’) ├─ (15): ‘size_t’: initial_svalue │ ╰─ m_reg: (12): ‘size_t’: decl_region(‘n_2(D)’) │ ╰─ parent: (9): frame_region(‘test’, index: 0, depth: 1) │ ╰─ parent: (1): stack region │ ╰─ parent: (0): root region ╰─ (16): ‘size_t’: constant_svalue (‘4’) I've already found both of these useful when debugging analyzer issues. The patch uses the former to update the output of -fdump-analyzer-exploded-nodes-2 and -fdump-analyzer-exploded-nodes-3. The older dumping functions within the analyzer are retained in case they turn out to still be useful for debugging. gcc/ChangeLog: * Makefile.in (OBJS-libcommon): Add text-art/tree-widget.o. * doc/analyzer.texi: Rewrite discussion of dumping state to cover the text_art::tree_widget-based dumps, with a more interesting example. * text-art/dump-widget-info.h: New file. * text-art/dump.h: New file. * text-art/selftests.cc (selftest::text_art_tests): Call text_art_tree_widget_cc_tests. * text-art/selftests.h (selftest::text_art_tree_widget_cc_tests): New decl. * text-art/theme.cc (ascii_theme::get_cppchar): Handle the various cell_kind::TREE_*.

2024-05-15diagnostics: simplify output of purely intraprocedural execution pathsDavid Malcolm1-16/+14
Diagnostic path printing was added in r10-5901-g4bc1899b2e883f. As of that commit, with -fdiagnostics-path-format=inline-events (the default), we print a vertical line to the left of the source line numbering, visualizing the stack depth and interprocedural calls and returns as indentation changes. For cases where the events on a thread are purely interprocedural, this line does nothing except take up space and complicate the output. This patch adds logic to omit it for such cases, simpifying the output, and, I believe, improving readability. gcc/ChangeLog: * diagnostic-path.h: Update leading comment to reflect intraprocedural cases. Fix typo in comment. * doc/invoke.texi: Update intraprocedural example. gcc/testsuite/ChangeLog: * c-c++-common/analyzer/allocation-size-multiline-1.c: Update expected results for purely intraprocedural path. * c-c++-common/analyzer/allocation-size-multiline-2.c: Likewise. * c-c++-common/analyzer/allocation-size-multiline-3.c: Likewise. * c-c++-common/analyzer/analyzer-verbosity-0.c: Likewise. * c-c++-common/analyzer/analyzer-verbosity-1.c: Likewise. * c-c++-common/analyzer/analyzer-verbosity-2.c: Likewise. * c-c++-common/analyzer/analyzer-verbosity-3.c: Likewise. * c-c++-common/analyzer/malloc-macro-inline-events.c: Likewise. Doing so for this file requires a rewrite since the paths prefixing the "in expansion of macro" lines become the only thing on their line and so are no longer pruned by multiline.exp logic for pruning extra content on non-blank lines. * c-c++-common/analyzer/malloc-paths-9-noexcept.c: Likewise. * c-c++-common/analyzer/setjmp-2.c: Likewise. * gcc.dg/analyzer/malloc-paths-9.c: Likewise. * gcc.dg/analyzer/out-of-bounds-multiline-2.c: Likewise. * gcc.dg/plugin/diagnostic-test-paths-2.c: Likewise. gcc/ChangeLog: * tree-diagnostic-path.cc (per_thread_summary::interprocedural_p): New.

PR analyzer/112974 and PR analyzer/112975 record false positives from the analyzer's taint detection where sanitization of the form if (VALUE CMP VALUE-OF-WIDER-TYPE) happens, but wasn't being "noticed" by the taint checker, due to the test being: (WIDER_TYPE)VALUE CMP VALUE-OF-WIDER-TYPE at the gimple level, and thus taint_state_machine recording sanitization of (WIDER_TYPE)VALUE, but not of VALUE.

2024-01-24analyzer kernel plugin: implement __check_object_size [PR112927]David Malcolm3-1/+69
PR analyzer/112927 reports a false positive from -Wanalyzer-tainted-size seen on the Linux kernel's drivers/char/ipmi/ipmi_devintf.c with the analyzer kernel plugin. The issue is that in: (A): if (msg->data_len > 272) { return -90; } (B): n = msg->data_len; __check_object_size(to, n); n = copy_from_user(to, from, n); the analyzer is treating __check_object_size as having arbitrary side effects, and, in particular could modify msg->data_len. Hence the sanitization that occurs at (A) above is treated as being for a different value than the size obtained at (B), hence the bogus warning at the call to copy_from_user. Fixed by extending the analyzer kernel plugin to "teach" it that __check_object_size has no side effects. gcc/testsuite/ChangeLog: PR analyzer/112927 * gcc.dg/plugin/analyzer_kernel_plugin.c (class known_function___check_object_size): New.

2023-12-06analyzer: fix taint false positives with UNKNOWN [PR112850]David Malcolm9-9/+210
PR analyzer/112850 reports a false positive from -Wanalyzer-tainted-allocation-size on the Linux kernel [1] where -fanalyzer complains that an allocation size is attacker-controlled despite the value being correctly sanitized against upper and lower limits. The root cause is that the expression is sufficiently complex to exceed the -param=analyzer-max-svalue-depth= threshold, currently at 12, with depth 13, and so it is treated as UNKNOWN. Hence the sanitizations are seen as comparisons of an UNKNOWN symbolic value against constants, and these were being ignored by the taint state machine. The expression in question is relatively typical for those seen in Linux kernel ioctl handlers, and I was surprised that it had exceeded the analyzer's default expression complexity limit. This patch addresses this problem in three ways: (a) the default value of the threshold parameter is increased, from 12 to 18, so that such expressions are precisely handled (b) adding a new -Wanalyzer-symbol-too-complex to warn when the symbol complexity limit is reached. This is off by default for users, and on by default in the test suite. (c) the taint state machine handles comparisons against UNKNOWN svalues by dropping all taint information on that execution path, so that if the complexity limit has been exceeded we don't generate false positives As well as fixing the taint false positive (PR analyzer/112850), the patch also fixes a couple of leak false positives seen on flex-generated scanners (PR analyzer/103546).

2023-12-06diagnostics: prettify JSON output formatsDavid Malcolm1-4/+41
Previously our JSON output emitted the JSON all on one line, with no indentation to show the structure of the values. Although it's easy to reformat such output (e.g. with "python -m json.tool"), I've found it's a pain to need to do so e.g. my text editor sometimes hangs when opening a multimegabyte json file all on one line. Similarly diff-ing is easier if the json is already formatted. This patch add whitespace to json output to show the structure. It turned out to be fairly easy to implement using pretty_printer's existing indentation machinery. The patch uses this formatting for the various JSON-based diagnostic output formats. For example, with this patch, the output from fdiagnostics-format=json-stderr looks like: [{"kind": "warning", "message": "stack-based buffer overflow", "option": "-Wanalyzer-out-of-bounds", "option_url": "https://gcc.gnu.org/onlinedocs/gcc/Static-Analyzer-Options.html#index-Wanalyzer-out-of-bounds", "children": [{"kind": "note", "message": "write of 350 bytes to beyond the end of ‘buf’", "locations": [{"caret": {"file": "../../src/gcc/testsuite/gcc.dg/analyzer/out-of-bounds-diagram-19.c", "line": 20, "display-column": 3, "byte-column": 3, "column": 3}, "finish": {"file": "../../src/gcc/testsuite/gcc.dg/analyzer/out-of-bounds-diagram-19.c", "line": 20, "display-column": 27, "byte-column": 27, "column": 27}}], "escape-source": false}, {"kind": "note", "message": "valid subscripts for ‘buf’ are ‘[0]’ to ‘[99]’", "locations": [{"caret": {"file": "../../src/gcc/testsuite/gcc.dg/analyzer/out-of-bounds-diagram-19.c", "line": 20, "display-column": 3, "byte-column": 3, "column": 3}, "finish": {"file": "../../src/gcc/testsuite/gcc.dg/analyzer/out-of-bounds-diagram-19.c", "line": 20, "display-column": 27, "byte-column": 27, "column": 27}}], "escape-source": false}], "column-origin": 1, ...snip...] I was able to update almost all of our DejaGnu test cases for JSON to handle this format tweak, and IMHO it improved the readability of these test cases, but a couple were more awkward.

2023-12-01diagnostics, analyzer: add optional per-diagnostic property bags to SARIFDavid Malcolm2-23/+15
I've found it useful in debugging the analyzer for the SARIF output to contain extra analyzer-specific data in each diagnostic. This patch: * adds a way for a diagnostic_metadata to populate a property bag within a SARIF "result" object based on a new vfunc * reworks how diagnostics are emitted within the analyzer so that a custom diagnostic_metadata subclass is used, which populates the property bag with information from the saved_diagnostic, and with a vfunc hook allowing for per-pending_diagnotic-subclass extra properties. Doing so makes it trivial to go from the SARIF output back to pertinent parts of the analyzer's internals (e.g. the index of the diagnostic within the ana::diagnostic_manager, the index of the ana::exploded_node, etc). It also replaces a lot of boilerplate in the "emit" implementations in the various pending_diagnostics subclasses. In particular, doing so fixes missing CVE metadata for -Wanalyzer-fd-phase-mismatch (where sm-fd.cc's fd_phase_mismatch::emit was failing to use its diagnostic_metadata instance). gcc/analyzer/ChangeLog: * analyzer.h (class saved_diagnostic): New forward decl. * bounds-checking.cc: Update for changes to pending_diagnostic::emit. * call-details.cc: Likewise. * diagnostic-manager.cc: Include "diagnostic-format-sarif.h".

2023-11-14input.h: eliminate implicit users of global_dc's file_cacheDavid Malcolm2-2/+3
This patch eliminates the following functions that implicitly used global_dc's file cache: extern char_span location_get_source_line (const char *file_path, int line); extern char_span get_source_file_content (const char *file_path); extern bool location_missing_trailing_newline (const char *file_path); in favor of explicitly using a specific file_cache throughout, and only using global_dc's file_cache in gcc-specific code. Rather than creating global_dc's file_cache the first time its needed, this patch simply creates one when a diagnostic_context is initialized, and eliminates diagnostic_file_cache_init.

2023-11-03diagnostics: convert diagnostic_context to a classDavid Malcolm2-3/+3
This patch: - converts "struct diagnostic_context" to "class diagnostic_context". - ensures all data members have an "m_" prefix, except for "printer", which has so many uses that renaming would be painful. - makes most of the data members private - converts much of the diagnostic_* functions to member functions of diagnostic_context, adding compatibility wrappers for users such as the Fortran frontend, and making as many as possible private.

2023-09-29Remove poly_int_podRichard Sandiford1-3/+3
poly_int was written before the switch to C++11 and so couldn't use explicit default constructors. This led to an awkward split between poly_int_pod and poly_int. poly_int simply inherited from poly_int_pod and added constructors, with the argumentless constructor having an empty body. But inheritance meant that poly_int had to repeat the assignment operators from poly_int_pod (again, no C++11, so no "using" to inherit base-class implementations). All that goes away if we switch to using default constructors. The main complication is ensuring that braced initialisation still gives a constexpr, so that static variables can be initialised without runtime code. The two problems here are: (1) When initialising a poly_int<N, wide_int> with fewer than N coefficients, the other coefficients need to be a zero of the same precision as the explicit coefficients. This was previously done in a for loop using wi::ints_for<...>::zero, but C++11 constexpr constructors can't have function bodies. The patch instead uses a series of delegated initialisers to fill in the implicit coefficients. (2) The initialisation in: void f(int x) { unsigned int foo {x}; } produces the warning: warning: narrowing conversion of 'x' from 'int' to 'unsigned int' [-Wnarrowing] whereas: void f(int x) { unsigned int foo = x; } does not. So switching to direct initialisation of the coeffs array would mean that: poly_uin64_t x = 0; would trigger a warning for using 0 rather than 0u. That seemed overly pedantic, so the patch adds explicit casts to the constructor. The complication is to do that without adding extra code to wide-int versions. The patch uses a new init_cast type for that. gcc/ * poly-int.h (poly_int_pod): Delete. (poly_coeff_traits::init_cast): New type. (poly_int_full, poly_int_hungry, poly_int_fullness): New structures. (poly_int): Replace constructors that take 1 and 2 coefficients with a general one that takes an arbitrary number of coefficients. Delegate initialization to two new private constructors, one of which uses the coefficients as-is and one of which adds an extra zero of the appropriate type (and precision, where applicable).

2023-09-14diagnostics: support multithreaded diagnostic pathsDavid Malcolm5-5/+217
This patch extends the existing diagnostic_path class so that as well as list of events, there is a list of named threads, with each event being associated with one of the threads. No GCC diagnostics take advantage of this, but GCC plugins may find a use for this; an example is provided in the testsuite. Given that there is still a single list of events within a diagnostic_path, the events in a diagnostic_path have a specific global ordering even if they are in multiple threads. Within the SARIF serialization, the patch adds the "executionOrder" property to threadFlowLocation objects (SARIF v2.1.0 3.38.11). This is 1-based in order to match the human-readable numbering of events shown in messages emitted by pretty-printer.cc's "%@". With -fdiagnostics-path-format=separate-events, the threads are not shown. With -fdiagnostics-path-format=inline-events, the threads and the per-thread stack activity are tracked and visalized separately. An example can be seen in the testsuite. gcc/analyzer/ChangeLog: * checker-event.h (checker_event::get_thread_id): New. * checker-path.h (class checker_path): Implement thread-related vfuncs via a single simple_diagnostic_thread instance named "main". gcc/ChangeLog: * diagnostic-event-id.h (diagnostic_thread_id_t): New typedef. * diagnostic-format-sarif.cc (class sarif_thread_flow): New.
