* remove GCC 4.2.1 build infrastructureEd Maste2020-02-292-79/+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 GCC has served us well, but version 4.2.1 is obsolete and not used by default on any architecture in FreeBSD.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.

* Convert gnu to using SRCTOPWarner Losh2017-03-121-3/+3
| | | | | | | | | | | | | | | 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.

* When MAKEOBJDIRPREFIX points to a case-insensitive file system, theMarcel Moolenaar2016-09-241-1/+1
| | | | | | | | | | | | | | | | | build can break when different source files create the same target files (case-insensitivity speaking). This is the case for object files compiled with -fpic and shared libraries. The former uses an extension of ".So", and the latter an extension ".so". Rename shared object files from *.So to *.pico to match what NetBSD does.

* Follow-up r297842: Rework header generation to fix always rebuilding.Bryan Drewery2016-04-181-5/+5
| | | | | | | | | | | | | This reworks the handling of common headers to just include the needed logic rather than invoke MAKE. This avoids the problem listed in r297842 and avoids other dependency tracking issues.

* META_MODE: Avoid changed build command every build.Bryan Drewery2016-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Because the file is generated with -f using another Makefile, 2 different Makefiles are trying to handle the .meta file for the target. The obvious .NOMETA_CMP or .NOMETA on the ${MAKE} targets don't work as they are very limited in scope in bmake. Using .PHONY fixes the problem and ensures that the ${MAKE} command is always ran to check if it is outdated in the sub-make. An example of the problem in gnu/lib/libgcc (with make -dM): /usr/obj/root/git/freebsd/gnu/lib/libgcc/tm.h.meta: 2: a build command has changed TARGET_CPU_DEFAULT="" HEADERS="options.h i386/biarch64.h i386/i386.h i386/unix.h i386/att.h dbxelf.h elfos-undef.h elfos.h freebsd-native.h freebsd-spec.h freebsd.h i386/x86-64.h i386/freebsd.h i386/freebsd64.h defaults.h" DEFINES="" /bin/sh /root/git/freebsd/gnu/lib/libgcc/../../../contrib/gcc/mkconfig.sh tm.h vs (cd /root/git/freebsd/gnu/lib/libgcc; make -f /root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile MFILE=/root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile GCCDIR=/root/git/freebsd/gnu/lib/libgcc/../../../contrib/gcc tm.h) Skipping meta for tm.h: .NOMETA (cd /root/git/freebsd/gnu/lib/libgcc; make -f /root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile MFILE=/root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile GCCDIR=/root/git/freebsd/gnu/lib/libgcc/../../../contrib/gcc tm.h) `tm.h' is up to date.

* Update bmake glue to build GCC 4.2.Alexander Kabaev2007-05-191-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | 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
