MFS r352754: Add WITH_PIE knob to build Position Independent ExecutablesMFC r344179: Add WITH_PIE knob to build Position Independent ExecutablesBuilding binaries as PIE allows the executable itself to be loaded at arandom address when ASLR is enabled (not just its shared libraries).With this change PIE objects have a .pieo extension and INTERNALLIBlibraries libXXX_pie.a.MK_PIE is disabled for some kerberos5 tools, Clang, and Subversion, asthey explicitly reference .a libraries in their Makefiles. These canbe addressed on an individual basis later. MK_PIE is also disabled forrtld-elf because it is already position-independent using bespokeMakefile rules.Currently only dynamically linked binaries will be built as PIE.MFC r344181: Fix Makefile conditional after r344179MFC r344182: Use make's :tl instead of checking "no" and "NO"MFC r344189: Fixup bsd.prog.mk after r344182MFC r344211: wlandebug: disable PIE to fix build failurelibifconfig is built as a static-only PRIVATELIB (and there is no _pie.aversion) so disable PIE in libifconfig's consumer.r345489: Fix GNU objdump build under WITH_PIEExplicitly specified bare .a libraries need ${PIE_SUFFIX}.r345490: Apply WITH_PIE changes to other binutils componentsFollowon to r345489, explicitly specified bare .a libraries need${PIE_SUFFIX} (although these still built).r345778: Fix gdb/kgdb build under WITH_PIEExplicitly specified bare .a libraries need ${PIE_SUFFIX}.Approved by: re (gjb)Sponsored by: The FreeBSD Foundation List of files: /freebsd-12.1/gnu/usr.bin/binutils/ld/Makefile

Rework how the ld link is handled in WORLDTMP from r322811.LLD_BOOTSTRAP (build) is independent of LLD_IS_LD (installed) so theyshould not be based on each other.This is related to upcoming WITH_SYSTEM_LINKER work.Reviewed by: emasteSponsored by: Dell EMCDifferential Revision: https://reviews.freebsd.org/D15836 List of files: /freebsd-12.1/gnu/usr.bin/binutils/ld/Makefile

Add WITH_LLD_AS_LD build knobIf set it installs LLD as /usr/bin/ld. LLD (as of version 3.9) is notcapable of linking the world and kernel, but can self-host and link manysubstantial applications. GNU ld continues to be used for the world andkernel build, regardless of how this knob is set.It is on by default for arm64, and off for all other CPU architectures.Sponsored by: The FreeBSD Foundation List of files: /freebsd-12.1/gnu/usr.bin/binutils/ld/Makefile

Switch GNU ld to be installed as ld.bfd and linked as ldWe intend to replace GNU ld with LLVM's lld, and on the path to therewe'll experiment with having lld installed or linked as /usr/bin/ld.Thus, make ld.bfd the primary install target for GNU ld, to laterfacilitate making the ld link optional.Reviewed by: davide, dimDifferential Revision: https://reviews.freebsd.org/D4790 List of files: /freebsd-12.1/gnu/usr.bin/binutils/ld/Makefile

b791fbe6 - META MODE: Don't create .meta files when symlinking sources into the obj directory.

Wed, 25 Nov 2015 19:44:43 +0000

META MODE: Don't create .meta files when symlinking sources into the obj directory.Tracking these leads to situations where meta mode will consider thefile to be out of date if /bin/sh or /bin/ln are newer than the sourcefile. There's no reason for meta mode to do this as make is alreadyhandling the rebuild dependency fine.Sponsored by: EMC / Isilon Storage Division List of files: /freebsd-12.1/gnu/usr.bin/binutils/ld/Makefile

8b2b71b4 - Fix ld not respecting --sysroot.

Tue, 24 Nov 2015 00:49:29 +0000

Fix ld not respecting --sysroot.ld(1) uses the /usr/libdata/ldscripts when linking. These scripts add in thedefault search paths of /lib and /usr/lib via 'SEARCH_DIR("DIR")'. Theseneed to be prefixed by '=' so that the --sysroot flag is respected. Thisis not a problem with buildworld since the TOOLS_PREFIX is baked into thecross-ld. However it is a problem when trying to use ld(1) with --sysrootanywhere else as it ends up still reading /lib and /usr/lib despite --sysroot.The default --sysroot (TARGET_SYSTEM_ROOT) is '/' for /usr/bin/ld.I found this while building with META MODE with uses only --sysroot with/usr/bin/ld, and found that libraries that I had not built in its sysrootdirectory were leaking in. This didn't happen with ports binutils either. Thiswould also impact external compiler support.Reviewed by: bapt, brooksMFC after: 2 weeksSponsored by: EMC / Isilon Storage DivisionDifferential Revision: https://reviews.freebsd.org/D4262 List of files: /freebsd-12.1/gnu/usr.bin/binutils/ld/Makefile
