2021-12-28driver: Improve option diagnostics [PR103465]Martin Liska1-0/+2
It happens that options are parsed and various diagnostics happen in finish_options. That's a proper place as the function is also called for optimize/target attributes (pragmas). However, it is possible that target overwrites an option from command line and so the diagnostics does not happen. That's fixed in the patch. - options are parsed and finish_options is called: if (opts->x_flag_unwind_tables && !targetm_common.unwind_tables_default && opts->x_flag_reorder_blocks_and_partition && (ui_except == UI_SJLJ || ui_except >= UI_TARGET)) { if (opts_set->x_flag_reorder_blocks_and_partition) inform (loc, "%<-freorder-blocks-and-partition%> does not support " "unwind info on this architecture"); opts->x_flag_reorder_blocks_and_partition = 0; opts->x_flag_reorder_blocks = 1; } It's not triggered because of opts->x_flag_unwind_tables is false by default, but the option is overwritten in target: ... if (TARGET_64BIT_P (opts->x_ix86_isa_flags)) { if (opts->x_optimize >= 1) SET_OPTION_IF_UNSET (opts, opts_set, flag_omit_frame_pointer, !USE_IX86_FRAME_POINTER); if (opts->x_flag_asynchronous_unwind_tables && TARGET_64BIT_MS_ABI) SET_OPTION_IF_UNSET (opts, opts_set, flag_unwind_tables, 1); ...

2021-11-10attribs: Implement -Wno-attributes=vendor::attr [PR101940]Marek Polacek1-0/+2
It is desirable for -Wattributes to warn about e.g. [[deprecate]] void g(); // typo, should warn However, -Wattributes also warns about vendor-specific attributes (that's because lookup_scoped_attribute_spec -> find_attribute_namespace finds nothing), which, with -Werror, causes grief. We don't want the -Wattributes warning for [[company::attr]] void f(); GCC warns because it doesn't know the "company" namespace; it only knows the "gnu" and "omp" namespaces. We could entirely disable warning about attributes in unknown scopes but then the compiler would also miss typos like [[company::attrx]] void f(); or [[gmu::warn_used_result]] int write(); so that is not a viable solution. A workaround is to use a #pragma: #pragma GCC diagnostic push #pragma GCC diagnostic ignored "-Wattributes" [[company::attr]] void f() {} #pragma GCC diagnostic pop but that's a mouthful and awkward to use and could also hide typos. In fact, any macro-based solution doesn't seem like a way forward. This patch implements -Wno-attributes=, which takes these arguments: company::attr company:: This option should go well with using @file: the user could have a file containing -Wno-attributes=vendor::attr1,vendor::attr2 and then invoke gcc with '@attrs' or similar. I've also added a new pragma which has the same effect: The pragma along with the new option should help with various static analysis tools.

2021-10-15Always default to DWARF2_DEBUG if not specified, warn about deprecated STABSRichard Biener1-0/+5
This makes defaults.h choose DWARF2_DEBUG if PREFERRED_DEBUGGING_TYPE is not specified by the target and errors out if DWARF DWARF is not supported. It also makes us warn when STABS is enabled but not the preferred debugging type and removes the corresponding diagnostic from the Ada frontend. The warnings are pruned from the testsuite output via prune_gcc_output. The following target configurations now explicitely default to STABS: pdp11-*-* pdp11 is a.out, dwarf support is difficult hppa[12]*-*-hpux10* does not support DWARF hppa[12]*-*-hpux11* likewise note that the hppa configs have been deprecated. Targets with DWARF support will now see > ./cc1 -quiet t.c -gstabs t.c: warning: STABS debugging information is obsolete and not supported anymore that is, -gstabs will still generate STABS but use will be diagnosed on targets where DWARF is available.

CTF is supported for C only. Currently, a warning is emitted if the -gctf command line option is specified for a non-C frontend. This warning is also used by the GCC testsuite framework - it skips adding -gctf to the list of debug flags for automated testing, if CTF is not supported for the frontend.

2021-07-19debug: Allow means for targets to opt out of CTF/BTF supportIndu Bhagat1-2/+9
CTF/BTF debug formats can be safely enabled for all ELF-based targets by default in GCC. CTF/BTF debug formats now adopt a similar approach as taken for DWARF debug format via the DWARF2_DEBUGGING_INFO. - By default, CTF/BTF formats can be enabled for all ELF-based targets. - By default, CTF/BTF formats can be disabled for all non ELF-based targets. - If the user passed a -gctf but CTF is not enabled for the target, GCC issues an error to the user (as is done currently with other debug formats) - "target system does not support the 'ctf' debug format". Analogous behavior for -gbtf command line option. A previous commit disabled the CTF and BTF testcases on the AIX platform. This is not necessary now that CTF and BTF debug formats are disabled by default on all non-ELF targets. GCC emits an error message when -gctf/-gbtf is used on such platforms and these tests will be skipped. gcc/ * config/elfos.h (CTF_DEBUGGING_INFO): New definition.

2021-06-28ipa-sra: Restructure how cloning and call redirection communicate (PR 93385)Martin Jambor1-0/+2
I was asked by Richi to split my fix for PR 93385 for easier review into IPA-SRA materialization refactoring and the actual DCE addition. Fortunately it was mostly natural except for a temporary weird condition in ipa_param_body_adjustments::modify_call_stmt. Additionally. In addition to the patch I posted previously, this one also deallocated the newly added summary in toplev::finalize and fixes a mistakenly uninitialized field. This is the first part which basically replaces performed_splits in clone_info and the code which generates it, keeps it up-to-date and consumes it with new edge summaries which are much nicer. It simply contains 1) a mapping from the original argument indices to the actual indices in the call statement as it is now, 2) information needed to identify arguments representing pass-through IPA-SRA splits with which have been added to the call arguments in place of an original argument/reference and 3) a delta to the index where va_args may start - so basically directly all the information that the consumer of performed_splits had to compute and we also do not need the weird dummy declarations. The main disadvantage is that the information has to be created (and kept up-to-date) for all call graph edges associated with the given statement from all clones (including inline clones) of the clone where splitting or removal happened first. But all of this happens during clone materialization so the only effect on WPA memory consumption is the removal of a pointer from clone_info. The statement modification code also has to know the statement from the original function in order to be able to locate the edge summaries which at this point are still keyed to these. However, the code is already quite heavily dependant on how things are structured in tree-inline.c and in order to fix bugs like these it probably has to be. The subsequent patch needs this new information to be able to remove arguments from calls during materialization and communicate this information to the call redirection. gcc/ChangeLog: 2021-05-17 Martin Jambor <mjambor@suse.cz> PR ipa/93385 * symtab-clones.h (clone_info): Removed member param_adjustments. * ipa-param-manipulation.h: Adjust initial comment to reflect how we deal with pass-through splits now.

2020-11-25libsanitizer: Add hwasan pass and associated gimple changesMatthew Malcomson1-1/+1
There are four main features to this change: 1) Check pointer tags match address tags. When sanitizing for hwasan we now put HWASAN_CHECK internal functions before memory accesses in the `asan` pass. This checks that a tag in the pointer being used match the tag stored in shadow memory for the memory region being used. These internal functions are expanded into actual checks in the sanopt pass that happens just before expansion into RTL. We use the same mechanism that currently inserts ASAN_CHECK internal functions to insert the new HWASAN_CHECK functions. 2) Instrument known builtin function calls. Handle all builtin functions that we know use memory accesses. This commit uses the machinery added for ASAN to identify builtin functions that access memory. The main differences between the approaches for HWASAN and ASAN are: - libhwasan intercepts much less builtin functions. - Alloca needs to be transformed differently (instead of adding redzones it needs to tag shadow memory and return a tagged pointer). - stack_restore needs to untag the shadow stack between the current position and where it's going. - `noreturn` functions can not be handled by simply unpoisoning the entire shadow stack -- there is no "always valid" tag. (exceptions and things such as longjmp need to be handled in a different way, usually in the runtime). For hardware implemented checking (such as AArch64's memory tagging extension) alloca and stack_restore will need to be handled by hooks in the backend rather than transformation at the gimple level. This will allow architecture specific handling of such stack modifications. 3) Introduce HWASAN block-scope poisoning Here we use exactly the same mechanism as ASAN_MARK to poison/unpoison variables on entry/exit of a block. In order to simply use the exact same machinery we're using the same internal functions until the SANOPT pass. This means that all handling of ASAN_MARK is the same. This has the negative that the naming may be a little confusing, but a positive that handling of the internal function doesn't have to be duplicated for a function that behaves exactly the same but has a different name. gcc/ChangeLog: * asan.c (asan_instrument_reads): New.

2020-11-25libsanitizer: mid-end: Introduce stack variable handling for HWASANMatthew Malcomson1-0/+3
Handling stack variables has three features. 1) Ensure HWASAN required alignment for stack variables When tagging shadow memory, we need to ensure that each tag granule is only used by one variable at a time. This is done by ensuring that each tagged variable is aligned to the tag granule representation size and also ensure that the end of each object is aligned to ensure the start of any other data stored on the stack is in a different granule. This patch ensures the above by forcing the stack pointer to be aligned before and after allocating any stack objects. Since we are forcing alignment we also use `align_local_variable` to ensure this new alignment is advertised properly through SET_DECL_ALIGN. 2) Put tags into each stack variable pointer Make sure that every pointer to a stack variable includes a tag of some sort on it. The way tagging works is: 1) For every new stack frame, a random tag is generated. 2) A base register is formed from the stack pointer value and this random tag. 3) References to stack variables are now formed with RTL describing an offset from this base in both tag and value. The random tag generation is handled by a backend hook. This hook decides whether to introduce a random tag or use the stack background based on the parameter hwasan-random-frame-tag. Using the stack background is necessary for testing and bootstrap. It is necessary during bootstrap to avoid breaking the `configure` test program for determining stack direction. Using the stack background means that every stack frame has the initial tag of zero and variables are tagged with incrementing tags from 1, which also makes debugging a bit easier. Backend hooks define the size of a tag, the layout of the HWASAN shadow memory, and handle emitting the code that inserts and extracts tags from a pointer. 3) For each stack variable, tag and untag the shadow stack on function prologue and epilogue. On entry to each function we tag the relevant shadow stack region for each stack variable. This stack region is tagged to match the tag added to each pointer to that variable. This is the first patch where we use the HWASAN shadow space, so we need to add in the libhwasan initialisation code that creates this shadow memory region into the binary we produce. This instrumentation is done in `compile_file`. When exiting a function we need to ensure the shadow stack for this function has no remaining tags. Without clearing the shadow stack area for this stack frame, later function calls could get false positives when those later function calls check untagged areas (such as parameters passed on the stack) against a shadow stack area with left-over tag. Hence we ensure that the entire stack frame is cleared on function exit. config/ChangeLog: * bootstrap-hwasan.mk: Disable random frame tags for stack-tagging during bootstrap. gcc/ChangeLog: * asan.c (struct hwasan_stack_var): New.

2020-11-25libsanitizer: options: Add hwasan flags and argument parsingMatthew Malcomson1-0/+9
These flags can't be used at the same time as any of the other sanitizers. We add an equivalent flag to -static-libasan in -static-libhwasan to ensure static linking. The -fsanitize=kernel-hwaddress option is for compiling targeting the kernel. This flag has defaults to match the LLVM implementation and sets some other behaviors to work in the kernel (e.g. accounting for the fact that the stack pointer will have 0xff in the top byte and to not call the userspace library initialisation routines). The defaults are that we do not sanitize variables on the stack and always recover from a detected bug. Since we are introducing a few more conflicts between sanitizer flags we refactor the checking for such conflicts to use a helper function which makes checking for such conflicts more easy and consistent. We introduce a backend hook `targetm.memtag.can_tag_addresses` that indicates to the mid-end whether a target has a feature like AArch64 TBI where the top byte of an address is ignored. Without this feature hwasan sanitization is not done. gcc/ChangeLog: * common.opt (flag_sanitize_recover): Default for kernel hwaddress. (static-libhwasan): New cli option. * config/aarch64/aarch64.c (aarch64_can_tag_addresses): New.

So, I've tried under debugger how it behaves and seems global_options_set is really an or of whether an option has been ever seen as explicit, either on the command line or in any of the option pragmas or optimize/target attributes seen so far, so it isn't something that can be relied on. The following patch implements the saving/restoring of the opts_set bits (though only for the options/variables saved by the generic options-save.c code, for the target specific stuff that isn't handled by the generic code the opts_set argument is now passed to the hook and the backends can choose e.g. to use a TargetSave variable to save the flags either individually or together in some bitmask (or ignore it if they never need opts_set for the options).

2020-08-12Fix up flag_cunroll_grow_size handling in presence of optimize attr [PR96535]Jakub Jelinek1-10/+0
As the testcase in the PR shows (not included in the patch, as it seems quite fragile to observe unrolling in the IL), the introduction of flag_cunroll_grow_size broke optimize attribute related to loop unrolling. The problem is that the new option flag is set (if not set explicitly) only in process_options and in rs6000_option_override_internal (and there only if global_init_p). So, this means that while it is Optimization option, it will only be set based on the command line -funroll-loops/-O3/-fpeel-loops or -funroll-all-loops, which means that if command line does include any of those, it is enabled even for functions that will through optimize attribute have all of those disabled, and if command line does not include those, it will not be enabled for functions that will through optimize attribute have any of those enabled. process_options is called just once, so IMHO it should be handling only non-Optimization option adjustments (various other options suffer from that too, but as this is a regression from 10.1 on the 10 branch, changing those is not appropriate). Similarly, rs6000_option_override_internal is called only once (with global_init_p) and then for target attribute handling, but not for optimize attribute handling. This patch moves the unrolling related handling from process_options into finish_options which is invoked whenever the options are being finalized, and the rs6000 specific parts into the override_options_after_change hook which is called for optimize attribute handling (and unfortunately also th cfun changes, but what the hook does is cheap) and I've added a call to that from rs6000_override_options_internal, so it is also called on cmdline processing and for target attribute. Furthermore, it stops using AUTODETECT_VALUE, which can work only once, and instead uses the global_options_set.x_... flags. 2020-08-12 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/96535 * toplev.c (process_options): Move flag_unroll_loops and flag_cunroll_grow_size handling from here to ... * opts.c (finish_options): ... here.

2020-08-03Removal of HSA offloading from gcc and libgompMartin Jambor1-3/+0
This patch removes the generation of HSAIL from the compiler, the HSA offloading plugin from libgomp and the associated testsuite tests and infrastructure bits from the respective testsuites. Apart from removal of the obvious files, I removed bits that I found by searching for HSA related terms and by re-tracing my steps and looking at the patches that introduced HSA in the first place. I did not remove everything these patches brought in, for example: - the mechanism to pass offload-target specific info from the application to the offloading plugin - but the same mechanism is also used to communicate number of teams and the thread limit to all offload targets. - run_func hook in gomp_device_descr stays too, although now it is not used. If some future offload target would like the ability to refuse to offload some functions, it can use it. It is easy to remove as a follow-up if it is considered clutter, though. - configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too. - Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant from gomp-constants.h) appears in the source of the amdgcn libgomp plugin, although I tend to think that code path is not ever used and this patch certainly removes it from the compiler. Nevertheless, it seems it has potential value beyond HSAIL and so I've kept it, it can of course always be easily removed in the future of GCN folk abandon it too. - I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA need to stay indefinitely too just so that no future offload target picks that number. - I have kept dg-require-effective-target offload_device_nonshared_as requirement of thests which have it. It is quite probable I missed some small HSA artifacts but those should be easy to remove later as we find them. include/ChangeLog: 2020-07-24 Martin Jambor <mjambor@suse.cz> * gomp-constants.h (GOMP_VERSION_HSA): Remove. gcc/ChangeLog: 2020-07-24 Martin Jambor <mjambor@suse.cz> * hsa-brig-format.h: Moved to brig/brigfrontend. * hsa-brig.c: Removed. * hsa-builtins.def: Likewise. * hsa-common.c: Likewise. * hsa-common.h: Likewise. * hsa-dump.c: Likewise. * hsa-gen.c: Likewise. * hsa-regalloc.c: Likewise. * ipa-hsa.c: Likewise. * omp-grid.c: Likewise. * omp-grid.h: Likewise. * Makefile.in (BUILTINS_DEF): Remove hsa-builtins.def.

2020-05-26revamp dump and aux output namesAlexandre Oliva1-18/+44
This patch simplifies (!!!) the logic governing the naming of dump files and auxiliary output files in the driver, in the compiler, and in the LTO wrapper. No changes are made to the naming of primary outputs, there are often ways to restore past behavior, and a number of inconsistencies are fixed. Some internal options are removed (-auxbase and -auxbase-strip), sensible existing uses of -dumpdir and -dumpbase options remain unchanged, additional useful cases are added, making for what is still admittedly quite complex. Extensive documentation and testcases provide numerous examples, from normal to corner cases. The most visible changes are: - aux and dump files now always go in the same directory, that defaults to the directory of the primary output, but that can be overridden with -dumpdir, -save-temps=*, or, preserving past behavior, with a -dumpbase with a directory component. - driver and compiler now have the same notion of naming of auxiliary outputs, e.g. .dwo files will no longer be in one location while the debug info suggests they are elsewhere, and -save-temps and .dwo auxiliary outputs now go in the same location as .su, .ci and coverage data, with consistent naming. - explicitly-specified primary output names guide not only the location of aux and dump outputs: the output base name is also used in their base name, as a prefix when also linking (e.g. foo.c bar.c -o foobar creates foobar-foo.dwo and foobar-bar.dwo with -gsplit-dwarf), or as the base name instead of the input name (foo.c -c -o whatever.o creates whatever.su rather than foo.su with -fstack-usage). The preference for the input file base name, quite useful for our testsuite, can be restored with -dumpbase "". When compiling and linking tests in the testsuite with additional inputs, we now use this flag. Files named in dejagnu board ldflags, libs, and ldscripts are now quoted in the gcc testsuite with -Wl, so that they are not counted as additional inputs by the compiler driver. - naming a -dumpbase when compiling multiple sources used to cause dumps from later compiles to overwrite those of earlier ones; it is now used as a prefix when compiling multiple sources, like an executable name above. - the dumpbase, explicitly specified or computed from output or input names, now also governs the naming of aux outputs; since aux outputs usually replaced the suffix from the input name, while dump outputs append their own additional suffixes, a -dumpbase-ext option is introduced to enable a chosen suffix to be dropped from dumpbase to form aux output names. - LTO dump and aux outputs were quite a mess, sometimes leaking temporary output names into -save-temps output names, sometimes conversely generating desirable aux outputs in temporary locations. They now obey the same logic of compiler aux and dump outputs, landing in the expected location and taking the linker output name or an explicit dumpbase overrider into account. - Naming of -fdump-final-insns outputs now follows the dump file naming logic for the .gkd files, and the .gk dump files generated in the second -fcompare-debug compilation get the .gk inserted before the suffix that -dumpbase-ext drops in aux outputs. gcc/ChangeLog: * common.opt (aux_base_name): Define.

For example, the following (hypothetical) error has a 3-event intraprocedural path: test.c: In function 'demo': test.c:29:5: error: passing NULL as argument 1 to 'PyList_Append' which requires a non-NULL parameter 29 | PyList_Append(list, item); | ^~~~~~~~~~~~~~~~~~~~~~~~~ 'demo': events 1-3 | | 25 | list = PyList_New(0); | | ^~~~~~~~~~~~~ | | | | | (1) when 'PyList_New' fails, returning NULL | 26 | | 27 | for (i = 0; i < count; i++) { | | ~~~ | | | | | (2) when 'i < count' | 28 | item = PyLong_FromLong(random()); | 29 | PyList_Append(list, item); | | ~~~~~~~~~~~~~~~~~~~~~~~~~ | | | | | (3) when calling 'PyList_Append', passing NULL from (1) as argument 1 | The patch adds a new "%@" format code for printing event IDs, so that in the above, the description of event (3) mentions event (1), showing the user where the bogus NULL value comes from (the event IDs are colorized to draw the user's attention to them). There is a separation between data vs presentation: the above shows how the diagnostic-printing code has consolidated the path into a single run of events, since all the events are near each other and within the same function; more complicated examples (such as interprocedural paths) might be printed as multiple runs of events. Examples of how interprocedural paths are printed can be seen in the test suite (which uses a plugin to exercise the code without relying on specific warnings using this functionality). Other output formats include - JSON, - printing each event as a separate "note", and - to not emit paths. gcc/ChangeLog: * Makefile.in (OBJS): Add tree-diagnostic-path.o. * common.opt (fdiagnostics-path-format=): New option.

2019-12-18Add diagnostic_metadata and CWE supportDavid Malcolm1-0/+2
This patch adds support for associating a diagnostic message with an optional diagnostic_metadata object, so that plugins can add extra data to their diagnostics (e.g. mapping a diagnostic to a taxonomy or coding standard such as from CERT or MISRA). Currently this only supports associating a CWE identifier with a diagnostic (which is what I'm using for the warnings in the analyzer patch kit), but adding a diagnostic_metadata class allows for future growth in this area without an explosion of further "warning_at" overloads for all of the different kinds of custom data that a plugin might want to add. This version of the patch renames the overly-general -fdiagnostics-show-metadata to -fdiagnostics-show-cwe and adds test coverage for it via a plugin. It also adds a note to the documentation that no GCC diagnostics currently use this; it's a feature for plugins (and, at some point, I hope, the analyzer). gcc/ChangeLog: * common.opt (fdiagnostics-show-cwe): Add. * diagnostic-core.h (class diagnostic_metadata): New forward decl. (warning_at): Add overload taking a const diagnostic_metadata &. (emit_diagnostic_valist): Add overload taking a const diagnostic_metadata *. * diagnostic-format-json.cc: Include "diagnostic-metadata.h". (json_from_metadata): New function. (json_end_diagnostic): Call it to add "metadata" child for diagnostics with metadata. (diagnostic_output_format_init): Clear context->show_cwe. * diagnostic-metadata.h: New file. * diagnostic.c: Include "diagnostic-metadata.h". (diagnostic_impl): Add const diagnostic_metadata * param. (diagnostic_n_impl): Likewise. (diagnostic_initialize): Initialize context->show_cwe. (diagnostic_set_info_translated): Initialize diagnostic->metadata. (get_cwe_url): New function. (print_any_cwe): New function. (diagnostic_report_diagnostic): Call print_any_cwe if the diagnostic has non-NULL metadata. (emit_diagnostic): Pass NULL as the metadata in the call to diagnostic_impl. (emit_diagnostic_valist): Likewise. (emit_diagnostic_valist): New overload taking a const diagnostic_metadata *. (inform): Pass NULL as the metadata in the call to diagnostic_impl.

2019-11-20drop attempt to reuse cgraph callees for -fcallgraph-infoAlexandre Oliva1-8/+0
The information in cgraph callees is released long before we get to the point in which -fcallgraph-info edges are dumped, or even expanded. It doesn't make sense to retain it longer: the edges created for -fcallgraph-info are much smaller, and they don't even coexist, so not even peak use grows. for gcc/ChangeLog * function.h (CALLEE_FROM_CGRAPH_P): Remove. * function.c (record_final_call): Record even calls that might have been in the cgraph. * toplev.c (dump_final_node_vcg): Skip iteration over cgraph callees.
