2021-08-16gcov: Add TARGET_GCOV_TYPE_SIZE target hookSebastian Huber1-1/+1
If -fprofile-update=atomic is used, then the target must provide atomic operations for the counters of the type returned by get_gcov_type(). This is a 64-bit type for targets which have a 64-bit long long type. On 32-bit targets this could be an issue since they may not provide 64-bit atomic operations. Allow targets to override the default type size with the new TARGET_GCOV_TYPE_SIZE target hook. If a 32-bit gcov type size is used, then there is currently a warning in libgcov-driver.c in a dead code block due to sizeof (counter) == sizeof (gcov_unsigned_t): libgcc/libgcov-driver.c: In function 'dump_counter': libgcc/libgcov-driver.c:401:46: warning: right shift count >= width of type [-Wshift-count-overflow] 401 | dump_unsigned ((gcov_unsigned_t)(counter >> 32), dump_fn, arg); | ^~ gcc/c-family/ * c-cppbuiltin.c (c_cpp_builtins): Define __LIBGCC_GCOV_TYPE_SIZE if flag_building_libgcc is true. gcc/ * config/sparc/rtemself.h (SPARC_GCOV_TYPE_SIZE): Define. * config/sparc/sparc.c (sparc_gcov_type_size): New.

If the -fprofile-info-section is used, then the gcov information is registered in a linker set. This is done by build_gcov_info_var_registration().

2020-11-16gcov: Add -fprofile-info-section supportSebastian Huber1-2/+26
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. Is there an example for this in the test suite? gcc/ * common.opt (fprofile-info-section): New. * coverage.c (build_gcov_info_var_registration): New.

2020-04-16Make it possible to have different instrumented and feedback builds without ↵Jan Hubicka1-0/+14
copying gcda files around [pr93401] Hi, in GCC 8 we changed -fprofile-generate=<path> to use mangled absolute paths in the <path> directory. This was necessary to avoid clashes of files when gcc is executed from different directories to build different sources of same filename. However this made it difficult to build projects on setups where instrumented build is done in one directory, feedback build in different and possibly training happens in yet another directory structure. This happens i.e. for Firefox builds for month or two. This patch adds -fprofile-prefix-path that can be used to inform gcc where the root of build directory is and strip it form the gcda filenames. This is similar to exisitng debug-prefix-map but without the map feature since it seems useless for profile data. We spent quite some time with Maritn Liska discussing options and found no better solution. I was looking how this work on LLVM and they produce single profdata file which is then transformed into kind of simple database by llvmprofdata tool. This database keys functions by filename and symbol name. If you arrane two files with same name define static variable with same symbol name this gets messedup and result in wrong info. So I think this is not very good solution and preffer the extra option. Bootstrapped/regtested x86_64-linux. I plan to commit it later today if there are no complains. I suppose our manual could have some central section on profile feedback explaining the whole setup at one place.

2018-09-28dumpfile.c: use prefixes other than 'note: ' for ↵David Malcolm1-5/+5
MSG_{OPTIMIZED_LOCATIONS|MISSED_OPTIMIZATION} As noted at Cauldron, dumpfile.c currently emits "note: " for all kinds of dump message, so that (after filtering) there's no distinction between MSG_OPTIMIZED_LOCATIONS vs MSG_NOTE vs MSG_MISSED_OPTIMIZATION in the textual output. This patch changes dumpfile.c so that the "note: " varies to show which MSG_* was used, with the string prefix matching that used for filtering in -fopt-info, hence e.g. directive_unroll_3.f90:24:0: optimized: loop unrolled 7 times and: pr19210-1.c:24:3: missed: missed loop optimization: niters analysis ends up with assumptions. The patch adds "dg-optimized" and "dg-missed" directives for use in the testsuite for matching these (with -fopt-info on stderr; they don't help for dumpfile output). The patch also converts the various problem-reporting dump messages in coverage.c:get_coverage_counts to use MSG_MISSED_OPTIMIZATION rather than MSG_OPTIMIZED_LOCATIONS, as the docs call out "optimized" as "information when an optimization is successfully applied", whereas "missed" is for "information about missed optimizations", and problems with profile data seem to me to fall much more into the latter category than the former. Doing so requires converting a few tests from using "-fopt-info" (which is implicitly "-fopt-info-optimized-optall") to getting the "missed" optimizations. Changing them to "-fopt-info-missed" added lots of noise from the vectorizer, so I changed these tests to use "-fopt-info-missed-ipa". gcc/ChangeLog: * coverage.c (get_coverage_counts): Convert problem-reporting dump messages from MSG_OPTIMIZED_LOCATIONS to MSG_MISSED_OPTIMIZATION. * dumpfile.c (kind_as_string): New function.

2017-08-30[19/77] Add a smallest_int_mode_for_size helper functionRichard Sandiford1-3/+3
This patch adds a wrapper around smallest_mode_for_size for cases in which the mode class is MODE_INT. Unlike (int_)mode_for_size, smallest_mode_for_size always returns a mode of the specified class, asserting if no such mode exists. smallest_int_mode_for_size therefore returns a scalar_int_mode rather than an opt_scalar_int_mode. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * machmode.h (smallest_mode_for_size): Fix formatting.
