 # REQUIRES: x86
 
-# LLD used to crash when linking against a DSO with an undefined STB_LOCAL
-# symbol in the global part of the dynamic symbol table (i.e. an STB_LOCAL
-# symbol with an index >= the sh_info of the dynamic symbol table section). Such
-# a DSO is very broken, because local symbols should precede all global symbols
-# in the symbol table, and because having a symbol that's both undefined and
-# STB_LOCAL is a nonsensical combination. Nevertheless, we should warn on such
-# input files instead of crashing.
-
-# We've found actual broken DSOs of this sort in the wild, but for this test, we
-# created a reduced broken input file. There are no tools capable of producing a
-# broken DSO of this nature, so instead we created a valid DSO with an undefined
-# global symbol in the dynamic symbol table and then manually edited the binary
-# to make that symbol local. The valid DSO was created as follows:
-
-```
-% cat undef.s
-.hidden bar
-bar:
-	movq	foo@GOT, %rax
-
-% llvm-mc -triple=x86_64-linux-gnu -filetype=obj -o undef.o undef.s
-% ld.lld --no-rosegment -shared -o undefined-local-symbol-in-dso.so undef.o
-% strip undef.so
-```
-
-# (--no-rosegment and stripping are unnecessary; they just produce a smaller
-# binary)
-
-# This DSO should only have a single dynamic symbol table entry for foo, and
-# then we can use a small C program to modify that symbol table entry to be
-# STB_LOCAL instead of STB_GLOBAL.
-
-```
-#include <elf.h>
-#include <stdio.h>
-
-int main(int argc, char *argv[]) {
-  FILE *F = fopen(argv[1], "rb+");
-
-  Elf64_Ehdr Ehdr;
-  fread(&Ehdr, sizeof(Ehdr), 1, F);
-  fseek(F, Ehdr.e_shoff, SEEK_SET);
-
-  Elf64_Shdr Shdr;
-  do {
-    fread(&Shdr, sizeof(Shdr), 1, F);
-  } while (Shdr.sh_type != SHT_DYNSYM);
-
-  Elf64_Sym Sym;
-  fseek(F, Shdr.sh_offset + sizeof(Elf64_Sym), SEEK_SET);
-  fread(&Sym, sizeof(Sym), 1, F);
-  Sym.st_info = STB_LOCAL << 4 | ELF64_ST_TYPE(Sym.st_info);
-  fseek(F, Shdr.sh_offset + sizeof(Elf64_Sym), SEEK_SET);
