https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241257 --- Comment #8 from Dimitry Andric <dim@FreeBSD.org> --- (In reply to Mike Cui from comment #5) > Because the base toolchain binaries are static I can almost always run ne= wer version on older systems. When I tried this going to 12.1 RC it didn't = work because ld.lld depended on a libc symbol I didn't have in 11. I understand that it can be a time-saver, but in general, even a statically linked binary from a newer release (and certainly a major release) is not guaranteed to run on an older kernel, specifically because there may have b= een changes in syscalls. That said, compilers and linkers tend to use a relatively minor set of thos= e, and also the ones that don't change behavior very often (e.g. reading/writi= ng files, basic process management). So these are less likely to break. :) --=20 You are receiving this mail because: You are the assignee for the bug.=
