2021-12-28driver: Improve option diagnostics [PR103465]Martin Liska1-57/+68
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); ...

2021-12-18PR target/32803: Add -Oz option for improved clang compatibility.Roger Sayle1-0/+10
This patch adds support for an -Oz command line option, aggressively optimizing for size at the expense of performance. GCC's current -Os provides a reasonable balance of size and performance, whereas -Oz is probably only useful for code size benchmarks such as CSiBE. Or so I thought until I read in https://news.ycombinator.com/item?id=25408853 that clang's -Oz sometimes outperforms -O[23s]; I suspect modern instruction decode stages can treat "pushq $1; popq %rax" as a short uop encoding. Instead of introducing a new global variable, this patch simply abuses the existing optimize_size by setting its value to 2. The only change in behaviour is the tweak to the i386 backend implementing the suggestion in PR target/32803 to use a short push/pop sequence for loading small immediate values (-128..127) on x86, matching the behaviour of LLVM. On x86_64, the simple function: int foo() { return 25; } currently generates with -Os: foo: movl $25, %eax // 5 bytes ret With the proposed -Oz, it generates: foo: pushq $25 // 2 bytes popq %rax // 1 byte ret On CSiBE, this results in a 0.94% improvement (3703513 bytes total down to 3668516 bytes). 2021-12-18 Roger Sayle <roger@nextmovesoftware.com> gcc/ChangeLog PR target/32803 * common.opt (Oz): New command line option. * doc/invoke.texi: Document the new -Oz option. * lto-wrapper.c (merge_and_complain, append_compiler_options): Treat OPT_Oz as synonymous with OPT_Os. * optc-save-gen.awk: Increase maximum value of optimize_size to 2. * opts.c (default_options_optimization) [OPT_Oz]: Handle OPT_Oz just like OPT_Os, except set opt->x_optimize_size to 2.

2021-11-19options: Make -Ofast switch off -fsemantic-interpositionMartin Jambor1-0/+1
Using -fno-semantic-interposition has been reported by various people to bring about considerable speed up at the cost of strict compliance to the ELF symbol interposition rules See for example https://fedoraproject.org/wiki/Changes/PythonNoSemanticInterpositionSpeedup As such I believe it should be implied by our -Ofast optimization level, not only so that benchmarks that can benefit run faster, but also so that people looking at -Ofast documentation for options that could speed their programs find it. gcc/ChangeLog: 2021-11-12 Martin Jambor <mjambor@suse.cz> * opts.c (default_options_table): Switch off flag_semantic_interposition at Ofast. * doc/invoke.texi (Optimize Options): Document that Ofast switches off -fsemantic-interposition.
2021-11-10attribs: Implement -Wno-attributes=vendor::attr [PR101940]Marek Polacek1-0/+20
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.

2021-11-01diagnostics: escape non-ASCII source bytes for certain diagnosticsDavid Malcolm1-0/+4
This patch adds support to GCC's diagnostic subsystem for escaping certain bytes and Unicode characters when quoting source code. Specifically, this patch adds a new flag rich_location::m_escape_on_output which is a hint from a diagnostic that non-ASCII bytes in the pertinent lines of the user's source code should be escaped when printed. The patch sets this for the following diagnostics: - when complaining about stray bytes in the program (when these are non-printable) - when complaining about "null character(s) ignored"); - for -Wnormalized= (and generate source ranges for such warnings) The escaping is controlled by a new option: -fdiagnostics-escape-format=[unicode|bytes] For example, consider a diagnostic involing a source line containing the string "before" followed by the Unicode character U+03C0 ("GREEK SMALL LETTER PI", with UTF-8 encoding 0xCF 0x80) followed by the byte 0xBF (a stray UTF-8 trailing byte), followed by the string "after", where the diagnostic highlights the U+03C0 character. By default, this line will be printed verbatim to the user when reporting a diagnostic at it, as: beforeπXafter ^ (using X for the stray byte to avoid putting invalid UTF-8 in this commit message) If the diagnostic sets the "escape" flag, it will be printed as: before<U+03C0><BF>after ^~~~~~~~ with -fdiagnostics-escape-format=unicode (the default), or as: before<CF><80><BF>after ^~~~~~~~ if the user supplies -fdiagnostics-escape-format=bytes. This only affects how the source is printed; it does not affect how column numbers that are printed (as per -fdiagnostics-column-unit= and -fdiagnostics-column-origin=). gcc/c-family/ChangeLog: * c-lex.c (c_lex_with_flags): When complaining about non-printable CPP_OTHER tokens, set the "escape on output" flag. gcc/ChangeLog: * common.opt (fdiagnostics-escape-format=): New.

2021-01-14Add GCC_EXTRA_DIAGNOSTIC_OUTPUT environment variable for fix-it hintsDavid Malcolm1-1/+3
GCC has had the ability to emit fix-it hints in machine-readable form since GCC 7 via -fdiagnostics-parseable-fixits and -fdiagnostics-generate-patch. The former emits additional specially-formatted lines to stderr; the option and its format were directly taken from a pre-existing option in clang. Ideally this could be used by IDEs so that the user can select specific fix-it hints and have the IDE apply them to the user's source code (perhaps turning them into clickable elements, perhaps with an "Apply All" option, etc). Eclipse CDT has supported this option in this way for a few years: https://bugs.eclipse.org/bugs/show_bug.cgi?id=497670 As a user of Emacs I would like Emacs to support such a feature. https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25987 tracks supporting GCC fix-it output in Emacs. The discussion there identifies two issues with the existing option: (a) columns in the output are specified as byte-offsets within the line (for exact compatibility with the option in clang), whereas emacs would prefer to consume them as what GCC 11 calls "display columns". https://gcc.gnu.org/onlinedocs/gcc/Diagnostic-Message-Formatting-Options.html#index-fdiagnostics-column-unit (b) injecting a command-line option into the build is a fiddly manual step, varying between build systems. It's far easier for the user if Emacs simply sets an environment variable when compiling, GCC uses this to enable the option if it recognizes the value, and the emacs compilation buffer decodes the additional lines of output and adds appropriate widgets. In some ways it is a workaround for not having a language server. Doing it this way means that for the various combinations of older and newer GCC and older and newer Emacs that a sufficiently modern combination of both can automatically support the rich fix-it UI, whereas other combinations will either not provide the envvar, or silently ignore it, gracefully doing nothing extra. Hence this patch adds a new GCC_EXTRA_DIAGNOSTIC_OUTPUT environment variable to GCC which enables output of machine-parseable fix-it hints. GCC_EXTRA_DIAGNOSTIC_OUTPUT=fixits-v1 is equivalent to the existing -fdiagnostics-parseable-fixits option. GCC_EXTRA_DIAGNOSTIC_OUTPUT=fixits-v2 is the same, but changes the column output mode to "display columns" rather than bytes, as required by Emacs. The discussion in that Emacs bug has some concerns about the encoding of these lines, and, indeed, the encoding of GCC's stderr in general: currently we emit a mixture of bytes and UTF-8; I believe we emit filenames as bytes, diagnostic messages as UTF-8, and quote source code in the original encoding (PR other/93067 covers converting it to UTF-8 on output). This patch prints octal-escaped bytes for bytes within filenames and replacement text that aren't printable (as per -fdiagnostics-parseable-fixits). gcc/ChangeLog: * diagnostic.c (diagnostic_initialize): Eliminate parseable_fixits_p in favor of initializing extra_output_kind from GCC_EXTRA_DIAGNOSTIC_OUTPUT.

2020-11-25libsanitizer: options: Add hwasan flags and argument parsingMatthew Malcomson1-16/+82
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.

2020-11-24Fix -ffast-math flags handling inconsistenciesUlrich Weigand1-26/+32
This patch implements the following set of changes: 1. If a component flag of -ffast-math (or -funsafe-math-optimizations) is explicitly set (or reset) on the command line, this should override any implicit change due to -f(no-)fast-math, no matter in which order the flags come on the command line. This change affects all flags. 2. Any component flag modified from its default by -ffast-math should be reset to the default by -fno-fast-math. This was previously not done for the following flags: -fcx-limited-range -fexcess-precision= 3. Once -ffinite-math-only is true, the -f(no-)signaling-nans flag has no meaning (if we have no NaNs at all, it does not matter whether there is a difference between quiet and signaling NaNs). Therefore, it does not make sense for -ffast-math to imply -fno-signaling-nans. (This is also a documentation change.) 4. -ffast-math is documented to imply -fno-rounding-math, however the latter setting is the default anyway; therefore it does not make sense to try to modify it from its default setting. 5. The __FAST_MATH__ preprocessor macro should be defined if and only if all the component flags of -ffast-math are set to the value that is documented as the effect of -ffast-math. The following flags were currently *not* so tested: -fcx-limited-range -fassociative-math -freciprocal-math -frounding-math (Note that we should still *test* for -fno-rounding-math here even though it is not set as to 4. -ffast-math -frounding-math should not set the __FAST_MATH__ macro.) This is also a documentation change. 2020-11-24 Ulrich Weigand <uweigand@de.ibm.com> gcc/ * doc/invoke.texi (-ffast-math): Remove mention of -fno-signaling-nans. Clarify conditions when __FAST_MATH__ preprocessor macro is defined. * opts.c (common_handle_option): Pass OPTS_SET to set_fast_math_flags and set_unsafe_math_optimizations_flags. (set_fast_math_flags): Add OPTS_SET argument, and use it to avoid setting flags already explicitly set on the command line. In the !set case, also reset x_flag_cx_limited_range and x_flag_excess_precision. Never reset x_flag_signaling_nans or x_flag_rounding_math.

2020-11-16gcov: Add -fprofile-info-section supportSebastian Huber1-0/+4
Register the profile information in the specified section instead of using a constructor/destructor. A pointer to the profile information generated by -fprofile-arcs or -ftest-coverage is placed in the specified section for each translation unit. This option disables the profile information registration through a constructor and it disables the profile information processing through a destructor. I am not sure how I can test this option. One approach would be to assemble a test file, then scan it and check that a .gcov_info section is present and no __gcov_init() and __gcov_exit() calls are present.

2020-11-10opts: Change `is incompatible with` messages to have standard parametrised formMatthew Malcomson1-56/+50
Hello, In a recent review for one of the hwasan patches Richard S. noticed there are quite a few errors of the form "%<someflag%> is incompatible with <otherflag%>". https://gcc.gnu.org/pipermail/gcc-patches/2020-October/556137.html In order to avoid this creating extra work for translators we would like to change these error messages to use the form "%qs is incompatible with %qs" and pass the flag as format arguments. This patch implements that change. There is only one change in the output the compiler produces from this patch, an error message of "-fsanitize=address and -fsanitize=kernel-address are incompatible with -fsanitize=thread" has been changed to "-fsanitize=thread is incompatible with -fsanitize=address|kernel-address". This matches the similar error messages for live patching which use the messages "-f<something> is incompatible with -flive-patching=inline-only-static|inline-clone". Ok for trunk? gcc/ChangeLog: * opts.c (control_options_for_live_patching): Reform 'is incompatible with' error messages to use a standard message with differing format arguments.

2020-08-12Fix up flag_cunroll_grow_size handling in presence of optimize attr [PR96535]Jakub Jelinek1-5/+15
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 Jambor1-29/+2
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 Oliva1-35/+0
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.

While testing the --with-documentation-root-url= changes, I run into [Wreturn-type] URL pointing to gfortran documentation where it obviously isn't documented. The following patch updates the list of options to match reality (on the other side -Wconversion-extra is gfortran only option documented in gfortran.texi). Or, perhaps better use the attached patch instead, which doesn't have a hardcoded list and instead uses the flags? I went through options.c and the updated list of options matches exactly the cases where CL_Fortran is set for "-W*" options together with CL_C and/or CL_CXX (ok, there is also -Wall and -Wextra, but hopefully we don't emit [Wall] or [Wextra] for anything). 2020-05-04 Jakub Jelinek <jakub@redhat.com> * opts.c (get_option_html_page): Instead of hardcoding a list of options common between C/C++ and Fortran only use gfortran/ documentation for warnings that have CL_Fortran set but not CL_C or CL_CXX.
