## Check that N_WEAK_DEF isn't set in the symbol table.
|
|
## This is different from ld64, which makes private extern weak symbols non-weak
|
|
## for binds and relocations, but it still marks them as weak in the symbol table.
|
|
## Since `nm -m` doesn't look at N_WEAK_DEF for N_PEXT symbols this is not
|
|
## observable via nm, but it feels slightly more correct.
|
|
## (It is observable in `llvm-objdump --syms` output.)
