install-name-tool-prepend-rpath.test

## This test checks prepending a new LC_RPATH load command to a MachO binary.

# RUN: yaml2obj %p/Inputs/i386.yaml -o %t.i386
# RUN: llvm-install-name-tool -add_rpath @executable_path/. %t.i386
# RUN: llvm-install-name-tool -prepend_rpath first_rpath %t.i386
# RUN: llvm-objdump -p %t.i386 | FileCheck --check-prefix=NEW-RPATH %s

# RUN: yaml2obj %p/Inputs/x86_64.yaml -o %t.x86_64
# RUN: llvm-install-name-tool -add_rpath @executable_path/. %t.x86_64
# RUN: llvm-install-name-tool -prepend_rpath first_rpath %t.x86_64
# RUN: llvm-objdump -p %t.x86_64 | FileCheck --check-prefix=NEW-RPATH %s

# NEW-RPATH:      cmd LC_RPATH
# NEW-RPATH-NEXT: cmdsize
# NEW-RPATH-NEXT: first_rpath

# NEW-RPATH:      cmd LC_RPATH
# NEW-RPATH-NEXT: cmdsize
# NEW-RPATH-NEXT: @executable_path/.

## Prepend with dylib loads:
# RUN: yaml2obj %p/Inputs/strip-all.yaml -o %t.dylib
# RUN: llvm-install-name-tool -prepend_rpath first_rpath %t.dylib
# RUN: llvm-objdump -p %t.dylib | FileCheck --check-prefix=DYLIB %s

# DYLIB:      cmd LC_RPATH
# DYLIB-NEXT: cmdsize
# DYLIB-NEXT: first_rpath

# RUN: not llvm-install-name-tool -prepend_rpath first_rpath %t.i386 2>&1 | \
# RUN:   FileCheck --check-prefix=DUPLICATE-RPATH %s

# DUPLICATE-RPATH: rpath 'first_rpath' would create a duplicate load command

## Prepend same RPATH twice:
# RUN: not llvm-install-name-tool -prepend_rpath @executable_X \
# RUN:                            -prepend_rpath @executable_X %t.i386 2>&1 | \
# RUN:   FileCheck --check-prefix=DOUBLE %s

# DOUBLE: rpath '@executable_X' would create a duplicate load command

## Prepend and delete RPATH:
# RUN: not llvm-install-name-tool -prepend_rpath foo \
# RUN:                            -delete_rpath foo %t.i386 2>&1 | \
# RUN:   FileCheck --check-prefix=DELETE %s

# DELETE: cannot specify both -prepend_rpath 'foo' and -delete_rpath 'foo'

## Prepend and replace RPATH:
# RUN: not llvm-install-name-tool -prepend_rpath foo \
# RUN:                            -rpath foo bar %t.i386 2>&1 | \
# RUN:   FileCheck --check-prefix=REPLACE %s

# REPLACE: cannot specify both -prepend_rpath 'foo' and -rpath 'foo' 'bar'

## Check that cmdsize accounts for NULL terminator:
# RUN: yaml2obj %p/Inputs/x86_64.yaml -o %t.x86_64
# RUN: llvm-install-name-tool -prepend_rpath abcd %t.x86_64
# RUN: llvm-objdump -p %t.x86_64 | FileCheck %s --check-prefix=RPATH-SIZE

# RPATH-SIZE:      cmd LC_RPATH
# RPATH-SIZE-NEXT: cmdsize 24
# RPATH-SIZE-NEXT: path abcd
