I'm trying to compile dynamic linker with `gold' linker.
During build with normal ld(1) there is a warning
cc [...] -elf -o ld-elf.so.1
LOCALBASE/bin/ld: warning: cannot find entry symbol lf; defaulting to 00000000000034d0
While it doesn't seem to affect `ld' it does for `gold'. The binary produced
by `gold' segfaults, e.g.
# from /head@215110
Core was generated by `sh'.
Program terminated with signal 11, Segmentation fault.
#0 .rtld_start () at /usr/src/libexec/rtld-elf/amd64/rtld_start.S:33
33 xorq %rbp,%rbp # Clear frame pointer for good form
(gdb) bt
#0 .rtld_start () at /usr/src/libexec/rtld-elf/amd64/rtld_start.S:33
#1 0x0000000000000001 in ?? ()
#2 0x00007fffffff0fe0 in ?? ()
#3 0x0000000000000000 in ?? ()
So, is `-elf' intended or it can be removed?
