## 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.
# RUN: llvm-readobj %t.o --string-dump .strtab --string-dump .shstrtab \
# RUN: | FileCheck %s --check-prefix=VALIDATE --implicit-check-not=bar --implicit-check-not=.blag
# VALIDATE: String dump of section '.strtab':
# VALIDATE: bazfoobar
# VALIDATE: String dump of section '.shstrtab':
# VALIDATE: .blam.blah.blag
## Case 1: Basic copy.
# RUN: llvm-objcopy %t.o %t.copy
# RUN: llvm-readobj --section-headers --symbols %t.copy | FileCheck %s --check-prefix=COPY
# COPY: Sections [
# COPY: Name: .blam.blah.blag (
# COPY: Name: .blah.blag (
# COPY: Name: .blag (
# COPY: Symbols [
# COPY: Name: bar (
# COPY: Name: foobar (
# COPY: Name: bazfoobar (
## Case 2: Rename section.
# RUN: llvm-objcopy %t.o %t.rename-section --rename-section .blah.blag=.blob.blab
# RUN: llvm-readobj --section-headers %t.rename-section \
# RUN: | FileCheck %s --check-prefix=RENAME-SECTION
# RENAME-SECTION: Sections [
# RENAME-SECTION: Name: .blam.blah.blag (
# RENAME-SECTION: Name: .blob.blab (
# RENAME-SECTION: Name: .blag (
## Case 3: Rename symbol.
# RUN: llvm-objcopy %t.o %t.rename-symbol --redefine-sym foobar=raboof
# RUN: llvm-readobj --symbols %t.rename-symbol \
# RUN: | FileCheck %s --check-prefix=RENAME-SYMBOL
# RENAME-SYMBOL: Symbols [
# RENAME-SYMBOL: Name: bar (
# RENAME-SYMBOL: Name: raboof (
# RENAME-SYMBOL: Name: bazfoobar (
## Case 4: Remove section.
# RUN: llvm-objcopy %t.o %t.remove-section -R .blah.blag
# RUN: llvm-readobj --section-headers %t.remove-section \
# RUN: | FileCheck %s --check-prefix=REMOVE-SECTION --implicit-check-not .blah.blag
# REMOVE-SECTION: Sections [
# REMOVE-SECTION: Name: .blam.blah.blag (
# REMOVE-SECTION: Name: .blag (
## Case 5: Remove symbol.
# RUN: llvm-objcopy %t.o %t.remove-symbol -N foobar
# RUN: llvm-readobj --symbols %t.remove-symbol \
# RUN: | FileCheck %s --check-prefix=REMOVE-SYMBOL --implicit-check-not foobar
