GPL Software in the Base System
One of the ongoing goals for the FreeBSD base system is a migration to modern, copyfree or at least more permissively licensed components. This page aims to summarise the aged or unmaintained GPL components in the base system, potential replacements, and progress.
Unowned Components
The following may have potential replacements but integrating them is not yet planned. If you are looking for a project, please evaluate how feasible the replacement is, or if there are any other alternatives.

Potential Replacement |
Comment |
as |
create new llvm-based as, create new elftoolchain as, or just remove |
Was not required for amd64 buildworld but now is for skein_block_asm.s. On i386 as is used for secure/lib/libcrypto/i386/*.s. 11 ports fail to build when /usr/bin/as does not exist. llvm-mc is a very basic assembler driver |
dialog |
LGPL. WITHOUT_DIALOG added in r306375 but removes bsdinstall, bsdconfig, dpv |
|
libssp |
It appears it may be removed |
This is part of GCC. NetBSD and Bionic libc have something called libssp but it is unclear if the functionality is the same. See SummerOfCode2015/FreeBSDLibcSecurityExtensions |

Switched to BSDL reimplementation by theraven@ in r320127 when compiler supports C++11 |
theraven@, emaste@ |
ld |
90% |
Is the default on arm64, armv7, and amd64, and bootstrap linker on i386. Ports are in good shape with lld, with some outstanding work to fix issues on i386. Other archs less well supported. See LLVM PR23214 for details. |
emaste@ |
|
libgomp |
70% |
Reported to be production quality as of LLVM 3.5+ |
dim@, emaste@ |
|
gcc |
90% |
Default compiler for tier 1, other archs in progress, needs external toolchain support before gcc can be removed from tier 2. Also see PortsAndClang. |
dim@ |
|
gcov |
llvm-cov |
75% |
llvm-cov can be installed as gcov and should function mostly as a drop-in replacement |
emaste@ |
gdb |
lldb, ports gdb |
80% |
Basic functionality works for amd64 and arm targets. See GdbRetirement and lldb. Ports gdb includes kgdb. |
emaste@, jhb@ |
grep |
80% |
BSD grep has been imported into HEAD, but GNU grep is still default. Use WITH_BSD_GREP to test. Optimization and bugfixing needed. Tracking PR |
gabor@, KyleEvans |
|
objdump |
llvm-objdump |
75% |
Some differences from GNU objdump including formatting, but broadly compatible. Not required by the build. |
dim@, emaste@ |
Sunset Components
The following are dependencies of other components, and will be removed when all dependent components are removed.

Switch to LLVM libgcc_eh, libgcc_s |
Ports exp-runs are requested for these changes:
Description |
Exp-run link |
Remove /usr/bin/as |
|
Remove /usr/bin/objdump |
|
lld as /usr/bin/ld |
