## This test shows that when symbol/section names are optimized in the string

|
## table to share the same entry, due to tail merging, llvm-objcopy operations
|
|
## function correctly without corrupting the names of unchanged sections/symbols.

# RUN: yaml2obj %s -o %t.o

## Sanity check that the strings have been pooled.

## Case 1: Basic copy.

## Case 3: Rename symbol.
|
|
# RUN: llvm-objcopy %t.o %t.rename-symbol --redefine-sym foobar=raboof

## Case 4: Remove section.
|
|
# RUN: llvm-objcopy %t.o %t.remove-section -R .blah.blag
