## Case 1: special symbol $ld$install_name affects the install name
## since the specified version 11.0.0 matches the target version 11.0.0

# RUN: %lld -o %t/libfoo1.dylib %t/libLDInstallName.tbd %t/foo.o -dylib -platform_version macos 11.0.0 11.0.0

# CASE1: /New (compatibility version 1.1.1, current version 5.0.0)

## Case 2: special symbol $ld$install_name does not affect the install name
## since the specified version 11.0.0 does not match the target version 12.0.0

# RUN: %lld -o %t/libfoo2.dylib %t/libLDInstallName.tbd %t/foo.o -dylib -platform_version macos 12.0.0 12.0.0
# RUN: llvm-otool -L %t/libfoo2.dylib | FileCheck --check-prefix=CASE2 %s
# CASE2: /Old (compatibility version 1.1.1, current version 5.0.0)

## Check that we emit a warning for an invalid os version.

# RUN: %no_fatal_warnings_lld -o %t/libfoo3.dylib %t/libLDInstallNameInvalid.tbd %t/foo.o -dylib \
# RUN:  -platform_version macos 11.0.0 11.0.0 2>&1 | FileCheck --check-prefix=INVALID-VERSION %s

# INVALID-VERSION: failed to parse os version, symbol '$ld$install_name$os11.a$/New' ignored

## Case 3: If there's another library that has '/New' as its original
## install_name, we should take current-version and compatibility-version from
## the first library we load with that install name. For a reexport,
## the first loaded library is the library doing the reexport, not the
## reexported library.
