This can produce up to 25% more compact debug<br/> information compared to earlier versions.<br/>- Many optimisations.<br/>- The existing malloc attribute has been extended so that it can be<br/> used to identify allocator/deallocator API pairs. A pair of new<br/> -Wmismatched-dealloc and -Wmismatched-new-delete warnings are added.<br/>- Other new warnings:<br/> -Wsizeof-array-div, enabled by -Wall, warns about divisions of two<br/> sizeof operators when the first one is applied to an array and the<br/> divisor does not equal the size of the array element.<br/> -Wstringop-overread, enabled by default, warns about calls to string<br/> functions reading past the end of the arrays passed to them as<br/> arguments.<br/> -Wtsan, enabled by default, warns about unsupported features in<br/> ThreadSanitizer (currently std::atomic_thread_fence).<br/>- Enchanced warnings:<br/> -Wfree-nonheap-object detects many more instances of calls to<br/> deallocation functions with pointers not returned from a dynamic<br/> memory allocation function.<br/> -Wmaybe-uninitialized diagnoses passing pointers or references to<br/> uninitialized memory to functions taking const-qualified arguments.<br/> -Wuninitialized detects reads from uninitialized dynamically<br/> allocated memory.<br/> -Warray-parameter warns about functions with inconsistent array forms.<br/> -Wvla-parameter warns about functions with inconsistent VLA forms.<br/>- Several new features from the upcoming C2X revision of the ISO C<br/> standard are supported with -std=c2x and -std=gnu2x.<br/>- Several C++20 features have been implemented.<br/>- The C++ front end has experimental support for some of the upcoming<br/> C++23 draft.<br/>- Several new C++ warnings.<br/>- Enhanced Arm, AArch64, x86, and RISC-V CPU support.<br/>- The implementation of how program state is tracked within<br/> -fanalyzer has been completely rewritten with many enhancements.<br/><br/>see https://gcc.gnu.org/gcc-11/changes.html for a full list.<br/><br/>major changes in GCC 12 include:<br/><br/>- An ABI incompatibility between C and C++ when passing or returning<br/> by value certain aggregates containing zero width bit-fields has<br/> been discovered on various targets. x86-64, ARM and AArch64<br/> will always ignore them (so there is a C ABI incompatibility<br/> between GCC 11 and earlier with GCC 12 or later), PowerPC64 ELFv2<br/> always take them into account (so there is a C++ ABI<br/> incompatibility, GCC 4.4 and earlier compatible with GCC 12 or<br/> later, incompatible with GCC 4.5 through GCC 11). RISC-V has<br/> changed the handling of these already starting with GCC 10. As<br/> the ABI requires, MIPS takes them into account handling function<br/> return values so there is a C++ ABI incompatibility with GCC 4.5<br/> through 11.<br/>- STABS: Support for emitting the STABS debugging format is<br/> deprecated and will be removed in the next release. All ports now<br/> default to emit DWARF (version 2 or later) debugging info or are<br/> obsoleted.<br/>- Vectorization is enabled at -O2 which is now equivalent to the<br/> original -O2 -ftree-vectorize -fvect-cost-model=very-cheap.<br/>- GCC now supports the ShadowCallStack sanitizer.<br/>- Support for __builtin_shufflevector compatible with the clang<br/> language extension was added.<br/>- Support for attribute unavailable was added.<br/>- Support for __builtin_dynamic_object_size compatible with the<br/> clang language extension was added.<br/>- New warnings:<br/> -Wbidi-chars warns about potentially misleading UTF-8<br/> bidirectional control characters.<br/> -Warray-compare warns about comparisons between two operands of<br/> array type.<br/>- Some new features from the upcoming C2X revision of the ISO C<br/> standard are supported with -std=c2x and -std=gnu2x.<br/>- Several C++23 features have been implemented.<br/>- Many C++ enhancements across warnings and -f options.<br/><br/>see https://gcc.gnu.org/gcc-12/changes.html for a full list. /src/external/gpl3/gcc/dist/libgfortran/generated/product_r16.c - 1.1.1.3 Sun Jul 30 05:21:29 UTC 2023 mrg initial import of GCC 10.3.0. main changes include:<br/><br/>caveats:<br/>- ABI issue between c++14 and c++17 fixed<br/>- profile mode is removed from libstdc++<br/>- -fno-common is now the default<br/><br/>new features:<br/>- new flags -fallocation-dce, -fprofile-partial-training,<br/> -fprofile-reproducible, -fprofile-prefix-path, and -fanalyzer<br/>- many new compile and link time optimisations<br/>- enhanced drive optimisations<br/>- openacc 2.6 support<br/>- openmp 5.0 features<br/>- new warnings: -Wstring-compare and -Wzero-length-bounds<br/>- extended warnings: -Warray-bounds, -Wformat-overflow,<br/> -Wrestrict, -Wreturn-local-addr, -Wstringop-overflow,<br/> -Warith-conversion, -Wmismatched-tags, and -Wredundant-tags<br/>- some likely C2X features implemented<br/>- more C++20 implemented<br/>- many new arm & intel CPUs known<br/><br/>hundreds of reported bugs are fixed. full list of changes<br/>can be found at:<br/><br/> https://gcc.gnu.org/gcc-10/changes.html /src/external/gpl3/gcc/dist/libgfortran/generated/product_r16.c - 1.1.1.2 Sat Apr 10 22:10:14 UTC 2021 mrg initial import of GCC 9.3.0. changes include:<br/><br/>- live patching support<br/>- shell completion help<br/>- generally better diagnostic output (less verbose/more useful)<br/>- diagnostics and optimisation choices can be emitted in json<br/>- asan memory usage reduction<br/>- many general, and specific to switch, inter-procedure,<br/> profile and link-time optimisations. from the release notes:<br/> "Overall compile time of Firefox 66 and LibreOffice 6.2.3 on<br/> an 8-core machine was reduced by about 5% compared to GCC 8.3"<br/>- OpenMP 5.0 support<br/>- better spell-guesser<br/>- partial experimental support for c2x and c++2a<br/>- c++17 is no longer experimental<br/>- arm AAPCS GCC 6-8 structure passing bug fixed, may cause<br/> incompatibility (restored compat with GCC 5 and earlier.)<br/>- openrisc support /src/external/gpl3/gcc/dist/libgfortran/generated/product_r16.c - 1.1.1.1 Sat Sep 05 07:52:55 UTC 2020 mrg
