* remove GCC 4.2.1 build infrastructureEd Maste2020-02-291-1109/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | As described in Warner's email message[1] to the FreeBSD-arch mailing list we have reached GCC 4.2.1's retirement date. At this time all supported architectures either use in-tree Clang, or rely on external toolchain (i.e., a contemporary GCC version from ports). GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later that year, in r171825. GCC has served us well, but version 4.2.1 is obsolete and not used by default on any architecture in FreeBSD. It does not support modern C and does not support arm64 or RISC-V. Thanks to everyone responsible for maintaining, updating, and testing GCC in the FreeBSD base system over the years. So long, and thanks for all the fish.

* Update libstdc++ configuration.Pedro F. Giffuni2018-07-161-20/+17
| | | | | | | | | | | | | Its been quite a while since the last time we updated this and since then we have grown iconv and a bunch of complex math functions. This only applies to the platforms which still use GCC 4.2.1 in the toolchain. Differential Revision: https://reviews.freebsd.org/D16289 Notes: svn path=/head/; revision=336351

| | | | | | | | | | | | | | to be gcc's default before r198344, calls to atomic builtins will not be expanded inline. Instead, they will be generated as calls to external functions (e.g. __sync_fetch_and_add_N), leading to linking errors later on. Put in a seatbelt that disables use of atomic builtins in libstdc++ and llvm, when tuning specifically for the real i386 CPU. This does not protect against all possible issues, but it is better than nothing. Notes: svn path=/head/; revision=227215

* GCC defines built-ins for atomic instructions found on i486 and higher.Tijl Coosemans2010-09-071-1/+1
| | | | | | | | | | | | | | | | | Because FreeBSD no longer supports the 80386 cpu all code targeting FreeBSD/i386 necessarily runs on i486 or higher so the compiler built-ins can be used by default inside libstdc++ and in C++ headers. This allows newly compiled C++ code to inline some atomic operations. Old binaries continue to use libstdc++ functions.

* Update bmake glue to build GCC 4.2.Alexander Kabaev2007-05-191-464/+353
| | | | | | | | | | | | | | | | | | | | | | | | Also: Switch FreeBSD to use libgcc_s.so.1. Use dl_iterate_phdr to locate shared objects' exception frame info instead of depending on older register_frame_info machinery. This allows us to avoid depending on libgcc_s.so.1 in binaries that do not use exception handling directly. As an additional benefit it breaks circular libc <=> libgcc_s.so.1 dependency too. Build newly added libgomp.so.1 library, the runtime support bits for OpenMP. Build LGPLed libssp library. Our libc provides our own BSD-licensed SSP callbacks implementation, so this library is only built to benefit applications that have hadcoded knowledge of libssp.so and libssp_nonshared.a. When linked in from command line, these libraries override libc implementation. Notes: svn path=/head/; revision=169718
