https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276597 --- Comment #5 from Dimitry Andric <dim@FreeBSD.org> --- (In reply to Mark Johnston from comment #4) The optimization to avoid building some cpp files works often, but not alwa= ys, due to subtle reasons. In some cases, if you turn on debug information, or change optimization levels, previously unreferenced symbols now do get referenced. In any case, I'm getting different errors here: --- all_subdir_libexec --- ld: error: undefined symbol: __asan_option_detect_stack_use_after_return >>> referenced by reloc.c:64 (/home/dim/src/freebsd/src/libexec/rtld-elf/am= d64/reloc.c:64) >>> reloc.o:(do_copy_relocations) >>> referenced by reloc.c:129 (/home/dim/src/freebsd/src/libexec/rtld-elf/a= md64/reloc.c:129) >>> reloc.o:(reloc_non_plt) >>> referenced by reloc.c:361 (/home/dim/src/freebsd/src/libexec/rtld-elf/a= md64/reloc.c:361) >>> reloc.o:(reloc_jmpslots) >>> referenced 53 more times ld: error: undefined symbol: __asan_stack_malloc_1 >>> referenced by reloc.c:64 (/home/dim/src/freebsd/src/libexec/rtld-elf/am= d64/reloc.c:64) >>> reloc.o:(do_copy_relocations) >>> referenced by rtld.c:1976 (/home/dim/src/freebsd/src/libexec/rtld-elf/r= tld.c:1976) >>> rtld.o:(find_symdef) >>> referenced by rtld.c:4028 (/home/dim/src/freebsd/src/libexec/rtld-elf/r= tld.c:4028) >>> rtld.o:(dlvsym) >>> referenced 10 more times ld: error: undefined symbol: __asan_report_load8_noabort >>> referenced by reloc.c:70 (/home/dim/src/freebsd/src/libexec/rtld-elf/am= d64/reloc.c:70) >>> reloc.o:(do_copy_relocations) >>> referenced by reloc.c:70 (/home/dim/src/freebsd/src/libexec/rtld-elf/am= d64/reloc.c:70) >>> reloc.o:(do_copy_relocations) >>> referenced by reloc.c:72 (/home/dim/src/freebsd/src/libexec/rtld-elf/am= d64/reloc.c:72) >>> reloc.o:(do_copy_relocations) >>> referenced 1769 more times in stage 4.4: building everything. --=20 You are receiving this mail because: You are the assignee for the bug.=
