2020-02-29remove GCC 4.2.1 build infrastructureEd Maste
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 GCC has served us well, but version 4.2.1 is obsolete and not used by default on any architecture in FreeBSD.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.

2017-03-12Convert gnu to using SRCTOPWarner Losh
Prefer SRCTOP over CURDIR/../../contrib, etc. However, retain the "up one level" instances of ../ because they are really relative to this part of the tree and not a means to find the root of the tree. As such, it's better to leave them since that further the goal of being able to move directories if watned to in the future.

2015-11-25META MODE: Don't create .meta files when symlinking sources into the obj ↵Bryan Drewery
directory. Tracking these leads to situations where meta mode will consider the file to be out of date if /bin/sh or /bin/ln are newer than the source file.

2013-09-12After r255321, clang uses libc++ by default. This leads to a lot ofDimitry Andric
errors when you enable WITH_GNUCXX to build libstdc++, since it will include C++ headers from the libc++ installation under ${WORLDTMP}, and those are not compatible with libstdc++ at all.

2011-11-06When one attempts to compile the tree with -march=i386, which also usedDimitry Andric
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

2010-09-07GCC defines built-ins for atomic instructions found on i486 and higher.Tijl Coosemans
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.
