On ARM targets (arm*-*-*), a bug introduced in GCC 5 that affects conformance to the procedure call standard (AAPCS) has been fixed. Many optimiser improvements DWARF-5 support. Many new and enhanced warnings. Warnings about format strings now underline the pertinent part of the string, and can offer suggested fixes. Several new warnings related to buffer overflows and buffer truncation. New __builtin_add_overflow_p, __builtin_sub_overflow_p, __builtin_mul_overflow_p built-ins added that test for overflow. The C++ front end has experimental support for all of the current C++17 draft. The -fverbose-asm option has been expanded to prints comments showing the source lines that correspond to the assembly. The gcc and g++ driver programs will now provide suggestions for misspelled arguments to command-line options. AArch64 specific: GCC has been updated to the latest revision of the procedure call standard (AAPCS64) to provide support for parameter passing when data types have been over-aligned. The ARMv8.2-A and ARMv8.3-A architecture are now supported. ARM specific: Support for the ARMv5 and ARMv5E architectures has been deprecated (which have no known implementations). A new command-line option -mpure-code has been added. It does not allow constant data to be placed in code sections. x86 specific: Support for the AVX-512 4FMAPS, 4VNNIW, VPOPCNTDQ and Software Guard Extensions (SGX) ISA extensions has been added. PPC specific: GCC now diagnoses inline assembly that clobbers register r2. RISC-V specific: Support for the RISC-V instruction set has been added. SH specific: Support for SH5/SH64 has been removed. Support for SH2A has been enhanced. /src/external/gpl3/gcc/dist/maintainer-scripts/gcc_release - 1.1.1.5 Sat Jan 19 10:14:14 UTC 2019 mrg branches: 1.1.1.4.2; 1.1.1.4.4; import GCC 6.4.0. see this url for details which are too large to include here: http://gcc.gnu.org/gcc-6/changes.html the main visible changes appear to be: - The default mode for C++ is now -std=gnu++14 instead of -std=gnu++98. - The C and C++ compilers now support attributes on enumerators. - Diagnostics can now contain "fix-it hints" - more warnings (some added to -Wall) /src/external/gpl3/gcc/dist/maintainer-scripts/gcc_release - 1.1.1.4 Fri Feb 02 01:59:07 UTC 2018 mrg import GCC 4.8.3 at r208254. these GCC PRs are fixed since r206687: c++/37140 c++/41174 c++/54652 c++/55800 c++/57043 c++/57524 c++/57899 c++/58466 c++/58504 c++/58606 c++/58632 c++/58639 c++/58672 c++/58812 c++/58814 c++/58835 c++/58837 c++/58845 c++/58873 c++/58965 c++/59097 c++/59224 c++/59646 c++/59838 c++/59989 c++/60046 c++/60108 c++/60146 c++/60182 c++/60187 c++/60216 c++/60219 c++/60248 c++/60272 c++/60274 c/59891 driver/60233 ipa/55260 libgcc/60166 middle-end/58809 middle-end/59860 middle-end/60004 middle-end/60221 middle-end/60291 objc/56870 other/56653 rtl-optimization/57422 rtl-optimization/60116 target/55426 target/57896 target/58710 target/59142 target/59379 target/59462 target/59695 target/59718 target/59777 target/59794 target/59826 target/59880 target/60017 target/60193 target/60207 tree-optimization/59903 tree-optimization/60115 tree-optimization/60183 tree-optimization/60276 /src/external/gpl3/gcc/dist/maintainer-scripts/gcc_release - 1.1.1.3 Mon Mar 03 02:43:18 UTC 2014 mrg import GCC 4.8 branch at r206687. highlights from: http://gcc.gnu.org/gcc-4.6/changes.html GCC now has stricter checks for invalid command-line options New -Wunused-but-set-variable and -Wunused-but-set-parameter warnings Many platforms have been obsoleted Link-time optimization improvements A new switch -fstack-usage has been added A new function attribute leaf was introduced A new warning, enabled by -Wdouble-promotion Support for selectively enabling and disabling warnings via #pragma GCC diagnostic has been added There is now experimental support for some features from the upcoming C1X revision of the ISO C standard Improved experimental support for the upcoming C++0x ISO C++ standard G++ now issues clearer diagnostics in several cases Updates for ARM, x86, MIPS, PPC/PPC64, SPARC Darwin, FreeBSD, Solaris 2, MinGW and Cygwin now all support __float128 on 32-bit and 64-bit x86 targets.
