llvm/test/tools/llvm-libtool-darwin/universal-bitcode-output.test

## This test checks that a correct universal binary is produced when
## llvm-libtool-darwin is given bitcode for multiple architectures.

## Check that the subtypes of cputype CPU_TYPE_ARM are stored in a fat file:
# RUN: llvm-as %p/Inputs/arm64-ios.ll -o %t-arm64.bc
# RUN: llvm-as %p/Inputs/armv7-ios.ll -o %t-armv7.bc

# RUN: llvm-libtool-darwin -static -o %t.lib %t-arm64.bc %t-armv7.bc

## Check that architectures are present in the universal output:
# RUN: llvm-lipo -info %t.lib | \
# RUN:   FileCheck %s --check-prefix=ARCHS -DFILE=%t.lib

# ARCHS: Architectures in the fat file: [[FILE]] are: armv7 arm64 

## Check that the files with the same architecture are combined in an archive:
# RUN: llvm-libtool-darwin -static -o %t.lib %t-arm64.bc %t-arm64.bc %t-armv7.bc
# RUN: llvm-lipo -info %t.lib | \
# RUN:   FileCheck %s --check-prefix=ARCHS -DFILE=%t.lib
# RUN: llvm-objdump --macho --arch all --all-headers %t.lib | \
# RUN:   FileCheck %s --check-prefix=UNIVERSAL-MEMBERS -DFILE=%t.lib -DPREFIX=%basename_t.tmp --implicit-check-not=Archive

# UNIVERSAL-MEMBERS:      Archive : [[FILE]] (architecture armv7)
# UNIVERSAL-MEMBERS-NEXT: __.SYMDEF
# UNIVERSAL-MEMBERS-NEXT: [[PREFIX]]-armv7.bc
# UNIVERSAL-MEMBERS:      Archive : [[FILE]] (architecture arm64)
# UNIVERSAL-MEMBERS-NEXT: __.SYMDEF
# UNIVERSAL-MEMBERS-NEXT: [[PREFIX]]-arm64.bc
# UNIVERSAL-MEMBERS-NEXT: [[PREFIX]]-arm64.bc

## Check that the files extracted from a universal output are archives:
# RUN: llvm-libtool-darwin -static -o %t.lib %t-arm64.bc %t-armv7.bc
# RUN: llvm-lipo %t.lib -thin armv7 -output %t-extracted-v7.a
# RUN: llvm-ar t %t-extracted-v7.a | \
# RUN:   FileCheck %s --check-prefix=EXTRACT --implicit-check-not={{.}} -DPREFIX=%basename_t.tmp
# RUN: llvm-nm --print-armap %t-extracted-v7.a | \
# RUN:   FileCheck %s --check-prefix=EXTRACT-SYMBOLS -DPREFIX=%basename_t.tmp --match-full-lines

# EXTRACT: [[PREFIX]]-armv7.bc

# EXTRACT-SYMBOLS:      Archive map
# EXTRACT-SYMBOLS-NEXT: _armv7 in [[PREFIX]]-armv7.bc
# EXTRACT-SYMBOLS-EMPTY:

## Check that the subtypes of cputype CPU_TYPE_X86_64 are stored in a fat file:
# RUN: llvm-as %p/Inputs/x86_64-osx.ll -o %t-x86_64.bc
# RUN: llvm-as %p/Inputs/x86_64h-osx.ll -o %t-x86_64_h.bc
# RUN: llvm-libtool-darwin -static -o %t.lib %t-x86_64.bc %t-x86_64_h.bc
# RUN: llvm-lipo -info %t.lib | \
# RUN:   FileCheck %s --check-prefix=ARCHS-X86 -DFILE=%t.lib

# ARCHS-X86: Architectures in the fat file: [[FILE]] are: x86_64 x86_64h

## Check that the subtypes of cputype CPU_TYPE_ARM64 are stored in a fat file:
## Testing it using llvm-objdump as, currently, there is no support for arm64e
## under llvm/lib/Object/MachOObjectFile.cpp.
# RUN: llvm-as %p/Inputs/arm64e-ios.ll -o %t-arm64e.bc
# RUN: llvm-libtool-darwin -static -o %t.lib %t-arm64.bc %t-arm64e.bc
# RUN: llvm-objdump --macho --arch all --all-headers %t.lib | \
# RUN:   FileCheck %s --check-prefix=UNIVERSAL-MEMBERS-ARM64 -DFILE=%t.lib -DPREFIX=%basename_t.tmp --implicit-check-not=Archive

# UNIVERSAL-MEMBERS-ARM64:      Archive : [[FILE]] (architecture arm64)
# UNIVERSAL-MEMBERS-ARM64-NEXT: __.SYMDEF
# UNIVERSAL-MEMBERS-ARM64-NEXT: [[PREFIX]]-arm64.bc
# UNIVERSAL-MEMBERS-ARM64:      Archive : [[FILE]]
# UNIVERSAL-MEMBERS-ARM64-NEXT: __.SYMDEF
# UNIVERSAL-MEMBERS-ARM64-NEXT: [[PREFIX]]-arm64e.bc

## Check that different cputypes are stored together in a fat file:
# RUN: llvm-libtool-darwin -static -o %t.lib %t-armv7.bc %t-x86_64.bc
# RUN: llvm-lipo -info %t.lib | \
# RUN:   FileCheck %s --check-prefix=ARCHS-CPU -DFILE=%t.lib

# ARCHS-CPU: Architectures in the fat file: [[FILE]] are: armv7 x86_64
