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

# RUN: yaml2obj --docnum=1 %s -o %t.64bit
# RUN: yaml2obj --docnum=2 %s -o %t.32bit
# RUN: echo -n abcdefg > %t.data

## Error case 1: Nonexistent input file is specified by --add-section.
# RUN: not llvm-objcopy --add-section __TEXT,__text=%t.missing %t.64bit %t.nonexistent-file 2>&1 \
# RUN:   | FileCheck %s -DINPUT=%t.64bit -DSECTION_DATA_FILE=%t.missing --check-prefix=NONEXSITENT-FILE
# NONEXSITENT-FILE: error: '[[INPUT]]': '[[SECTION_DATA_FILE]]': {{[Nn]}}o such file or directory

## Error case 2: Too long segment name.
# RUN: not llvm-objcopy --add-section __TOOOOOOOOO_LONG,__text=%t.data %t.64bit %t.too-long-seg-name 2>&1 \
# RUN:   | FileCheck %s -DINPUT=%t.64bit --check-prefix=TOO-LONG-SEG-NAME
# TOO-LONG-SEG-NAME: error: '[[INPUT]]': too long segment name: '__TOOOOOOOOO_LONG'

## Case 1: Add a new section into an existing segment.
# RUN: llvm-objcopy --add-section __TEXT,__text=%t.data %t.64bit %t.out1.64bit
# RUN: llvm-objcopy --add-section __TEXT,__text=%t.data %t.32bit %t.out1.32bit

# RUN: llvm-readobj --sections --section-data %t.out1.32bit \
# RUN:   | FileCheck %s --check-prefixes=32BIT,COMMON,CASE1

## Case 2: Add a new section into a nonexistent segment.
# RUN: llvm-objcopy --add-section __FOO,__bar=%t.data %t.64bit %t.out2.64bit
# RUN: llvm-objcopy --add-section __FOO,__bar=%t.data %t.32bit %t.out2.32bit

# RUN: llvm-readobj --sections --section-data --macho-segment %t.out2.32bit \
# RUN:   | FileCheck %s --check-prefixes=32BIT,COMMON,CASE2,CASE2-32BIT

## Case 3: Add a new section with /dev/null.
# RUN: llvm-objcopy --add-section __TEXT,__text=/dev/null %t.64bit %t.devnull
# RUN: llvm-readobj --sections --section-data %t.devnull \
# RUN:   | FileCheck %s --check-prefixes=64BIT,COMMON,DEVNULL
