## This test checks updating a dependent shared library install name in a MachO binary.
# RUN: yaml2obj %s -o %t
## Specifying -change once:
# RUN: cp %t %t.copy
# RUN: llvm-install-name-tool -change /usr/dylib/LOAD /usr/long/long/dylib/LOAD %t.copy
# RUN: llvm-objdump -p %t.copy | FileCheck %s --check-prefix=CHANGE --implicit-check-not='name /usr'
# CHANGE: name /usr/long/long/dylib/LOAD
# CHANGE: name /usr/dylib/WEAK
## Specifying -change multiple times:
# RUN: cp %t %t.copy
# RUN: llvm-install-name-tool -change /usr/dylib/WEAK /usr/sh/WEAK \
# RUN: -change /usr/dylib/LOAD /usr/sh/LOAD %t.copy
# RUN: llvm-objdump -p %t.copy | FileCheck %s --check-prefix=CHANGE-MULTIPLE --implicit-check-not='name /usr'
# CHANGE-MULTIPLE: name /usr/sh/LOAD
# CHANGE-MULTIPLE: name /usr/sh/WEAK
## Changing same dependent library name multiple times:
# RUN: cp %t %t.copy
# RUN: llvm-install-name-tool -change /usr/dylib/LOAD /usr/LOAD \
# RUN: -change /usr/dylib/LOAD /usr/XXXX %t.copy
# RUN: llvm-objdump -p %t.copy | FileCheck %s --check-prefix=CHANGE-REPEAT --implicit-check-not='name /usr'
# CHANGE-REPEAT: name /usr/LOAD
# CHANGE-REPEAT: name /usr/dylib/WEAK
## Specifying dependent library names in a chain:
# RUN: cp %t %t.copy
# RUN: llvm-install-name-tool -change /usr/dylib/LOAD /usr/XX/LOAD \
# RUN: -change /usr/XX/LOAD /usr/YY/LOAD %t.copy
# RUN: llvm-objdump -p %t.copy | FileCheck %s --check-prefix=CHANGE-CHAIN --implicit-check-not='name /usr'
# CHANGE-CHAIN: name /usr/XX/LOAD
# CHANGE-CHAIN: name /usr/dylib/WEAK
## Changing multiple dependent library names where one exists and the other doesn't:
# RUN: cp %t %t.copy
# RUN: llvm-install-name-tool -change /usr/dylib/LOAD /usr/JOJO/LOAD \
# RUN: -change /usr/BIZARRE /usr/KOKO/LOAD %t.copy
# RUN: llvm-objdump -p %t.copy | FileCheck %s --check-prefix=CHANGE-SWITCH --implicit-check-not='name /usr'
# CHANGE-SWITCH: name /usr/JOJO/LOAD
# CHANGE-SWITCH: name /usr/dylib/WEAK
## Changing to a common dependent library name:
# RUN: cp %t %t.copy
# RUN: llvm-install-name-tool -change /usr/dylib/LOAD /usr/COMMON \
# RUN: -change /usr/dylib/WEAK /usr/COMMON %t.copy
# RUN: llvm-objdump -p %t.copy | FileCheck %s --check-prefix=CHANGE-COMMON --implicit-check-not='name /usr'
# CHANGE-COMMON: name /usr/COMMON
# CHANGE-COMMON: name /usr/COMMON
## Change all common dependent library names at once:
# RUN: llvm-install-name-tool -change /usr/COMMON /usr/ONCE %t.copy
# RUN: llvm-objdump -p %t.copy | FileCheck %s --check-prefix=CHANGE-ONCE --implicit-check-not='name /usr'
# CHANGE-ONCE: name /usr/ONCE
# CHANGE-ONCE: name /usr/ONCE
## Check that -change option has no effect if the binary doesn't contain old install name:
# RUN: cp %t %t1
# RUN: llvm-install-name-tool -change /usr/JOJO/LOAD /usr/XX/LOAD \
# RUN: -change /usr/KOKO/WEAK /usr/YY/WEAK %t
# RUN: cmp %t %t1
## Missing a -change argument:
# RUN: not llvm-install-name-tool %t -change /usr/ONCE 2>&1 | \
# RUN: FileCheck %s --check-prefix=MISSING
## Missing both -change arguments:
# RUN: not llvm-install-name-tool %t -change 2>&1 | \
# RUN: FileCheck %s --check-prefix=MISSING
# MISSING: missing argument to -change option
