This can produce up to 25% more compact debug information compared to earlier versions.- Many optimisations.- The existing malloc attribute has been extended so that it can be used to identify allocator/deallocator API pairs. A pair of new -Wmismatched-dealloc and -Wmismatched-new-delete warnings are added.- Other new warnings: -Wsizeof-array-div, enabled by -Wall, warns about divisions of two sizeof operators when the first one is applied to an array and the divisor does not equal the size of the array element. -Wstringop-overread, enabled by default, warns about calls to string functions reading past the end of the arrays passed to them as arguments. -Wtsan, enabled by default, warns about unsupported features in ThreadSanitizer (currently std::atomic_thread_fence).- Enchanced warnings: -Wfree-nonheap-object detects many more instances of calls to deallocation functions with pointers not returned from a dynamic memory allocation function. -Wmaybe-uninitialized diagnoses passing pointers or references to uninitialized memory to functions taking const-qualified arguments. -Wuninitialized detects reads from uninitialized dynamically allocated memory. -Warray-parameter warns about functions with inconsistent array forms. -Wvla-parameter warns about functions with inconsistent VLA forms.- Several new features from the upcoming C2X revision of the ISO C standard are supported with -std=c2x and -std=gnu2x.- Several C++20 features have been implemented.- The C++ front end has experimental support for some of the upcoming C++23 draft.- Several new C++ warnings.- Enhanced Arm, AArch64, x86, and RISC-V CPU support.- The implementation of how program state is tracked within -fanalyzer has been completely rewritten with many enhancements.see https://gcc.gnu.org/gcc-11/changes.html for a full list.major changes in GCC 12 include:- An ABI incompatibility between C and C++ when passing or returning by value certain aggregates containing zero width bit-fields has been discovered on various targets. x86-64, ARM and AArch64 will always ignore them (so there is a C ABI incompatibility between GCC 11 and earlier with GCC 12 or later), PowerPC64 ELFv2 always take them into account (so there is a C++ ABI incompatibility, GCC 4.4 and earlier compatible with GCC 12 or later, incompatible with GCC 4.5 through GCC 11). RISC-V has changed the handling of these already starting with GCC 10. As the ABI requires, MIPS takes them into account handling function return values so there is a C++ ABI incompatibility with GCC 4.5 through 11.- STABS: Support for emitting the STABS debugging format is deprecated and will be removed in the next release. All ports now default to emit DWARF (version 2 or later) debugging info or are obsoleted.- Vectorization is enabled at -O2 which is now equivalent to the original -O2 -ftree-vectorize -fvect-cost-model=very-cheap.- GCC now supports the ShadowCallStack sanitizer.- Support for __builtin_shufflevector compatible with the clang language extension was added.- Support for attribute unavailable was added.- Support for __builtin_dynamic_object_size compatible with the clang language extension was added.- New warnings: -Wbidi-chars warns about potentially misleading UTF-8 bidirectional control characters. -Warray-compare warns about comparisons between two operands of array type.- Some new features from the upcoming C2X revision of the ISO C standard are supported with -std=c2x and -std=gnu2x.- Several C++23 features have been implemented.- Many C++ enhancements across warnings and -f options.see https://gcc.gnu.org/gcc-12/changes.html for a full list.

The o32 64-bit floating-point register support is now obsolete and has been removed. It has been replaced by three ABI extensions FPXX, FP64A, and FP64. The meaning of the -mfp64 command-line option has changed. It is now used to enable the FP64A and FP64 ABI extensions.
