Older versions of LLD fail with big-endian compressed debug sections. This was fixed in LLD upstream (commit c6ebc651b6fa) and merged to FreeBSD main (commit d69d07569ee2) by dim. External toolchains (e.g. the llvm12 package) will not yet have the fix. These may be used to link against base system .a archives, so compressed debug sections would cause trouble even though the base system is fixed. Enable compressed debug sections again, for little-endian targets only. As discussed on freebsd-hackers I expect to undo this in the future (using compressed debug everywhere), once fixed versions of lld are widely available. Note that to be pedantically correct we should check both the compiler and the linker for compressed debug support, but given the external toolchain constraint the extra complexity does not seem worthwhile.  https://lists.freebsd.org/archives/freebsd-hackers/2021-August/000188.html PR: 257638 Reported by: jrtc27 [impact of .a archives] Discussed with: imp Relnotes: Yes Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D31454 Revert "Disable compressed debug by default" This reverts commit 89ed2ecb14ceabc27883282cf96559a9e7d52717. share/mk/bsd.compiler.mk | 9 ++++++++- share/mk/bsd.sys.mk | 2 +- 2 files changed, 9 insertions(+), 2 deletions(-) -- You are receiving this mail because: You are the assignee for the bug.
