## Show that llvm-objcopy adds a new section into a 32-bit object file if
## --add-section is given.

# RUN: yaml2obj %s -o %t
# RUN: echo -n abcdefg > %t.data

## Case 1: Add a new section into an existing segment.
# RUN: llvm-objcopy --add-section __TEXT,__bar=%t.data %t %t.out1
# RUN: llvm-readobj --sections --section-data %t.out1 \
# RUN:   | FileCheck %s --check-prefixes=COMMON,CASE1

## Case 2: Add a new section into a nonexistent segment.
# RUN: llvm-objcopy --add-section __FOO,__bar=%t.data %t %t.out2
# RUN: llvm-readobj --sections --section-data %t.out2 \
# RUN:   | FileCheck %s --check-prefixes=COMMON,CASE2

## Case 3: Add a new section into an existing segment using /dev/null as an input.
# RUN: llvm-objcopy --add-section __TEXT,__bar=/dev/null %t %t.out3
# RUN: llvm-readobj --sections --section-data %t.out3 \
# RUN:   | FileCheck %s --check-prefixes=COMMON,CASE3
