## This test checks updating a LC_RPATH load command in a MachO binary.

# RUN: yaml2obj %s -o %t

## Updating a single RPath entry:
# RUN: llvm-install-name-tool -rpath @executable_a/. @executable_A/. %t
# RUN: llvm-objdump -p %t | \
# RUN:   FileCheck %s --check-prefix=RPATHS --implicit-check-not=@executable

# RPATHS: @executable_A/.
# RPATHS: @executable_short_test
# RPATHS: @executable_long_test/.
# RPATHS: @executable_d/.

## Updating multiple RPath entries:
# RUN: llvm-install-name-tool -rpath @executable_short_test/. @executable_test/. \
# RUN:                        -rpath @executable_long_test/. @executable_long_long_test/. %t
# RUN: llvm-objdump -p %t | \
# RUN:   FileCheck %s --check-prefix=RPATHS-MULTIPLE --implicit-check-not=@executable

# RPATHS-MULTIPLE: @executable_A/.
# RPATHS-MULTIPLE: @executable_test/.
# RPATHS-MULTIPLE: @executable_long_long_test/.
# RPATHS-MULTIPLE: @executable_d/.

## Check that cmdsize accounts for NULL terminator:
# RUN: llvm-install-name-tool -rpath @executable_A/. ABCD %t
# RUN: llvm-objdump -p %t | FileCheck %s --check-prefix=RPATH-SIZE

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

## Updating and adding different RPaths:
# RUN: llvm-install-name-tool -rpath @executable_d/. @executable_D/. \
# RUN:                        -add_rpath @executable_e/. %t
# RUN: llvm-objdump -p %t | FileCheck %s --check-prefix=RPATHS-ADD --implicit-check-not=@executable

# RPATHS-ADD: ABCD
# RPATHS-ADD: @executable_test/.
# RPATHS-ADD: @executable_long_long_test/.
# RPATHS-ADD: @executable_D/.
# RPATHS-ADD: @executable_e/.

## Updating and deleting different RPaths:
# RUN: llvm-install-name-tool -rpath @executable_D/. @executable_d/. \
# RUN:                        -delete_rpath @executable_e/. %t
# RUN: llvm-objdump -p %t | FileCheck %s --check-prefix=RPATHS-DELETE --implicit-check-not=@executable

# RPATHS-DELETE: ABCD
# RPATHS-DELETE: @executable_test/.
# RPATHS-DELETE: @executable_long_long_test/.
# RPATHS-DELETE: @executable_d/.

# RUN: cp %t %t1

## Updating multiple RPath entries where one exists and the other doesn't:
# RUN: not llvm-install-name-tool -rpath @executable_test/. @executable/. \
# RUN:                            -rpath @executable_long_test/. @executable_long_longest/. %t 2>&1 | \
# RUN:   FileCheck %s --check-prefix=RPATHS-FAIL
# RUN: cmp %t %t1

# RPATHS-FAIL: no LC_RPATH load command with path: @executable_long_test/.

## Updating a nonexistent RPath:
# RUN: not llvm-install-name-tool -rpath @executable_a/. @executable_AA/. %t 2>&1 | \
# RUN:   FileCheck %s --check-prefix=ABSENT-RPATH
# RUN: cmp %t %t1

# ABSENT-RPATH: no LC_RPATH load command with path: @executable_a/.

## Updating to an existing RPath:
# RUN: not llvm-install-name-tool -rpath @executable_d/. ABCD %t 2>&1 | \
# RUN:   FileCheck %s --check-prefix=EXISTING
# RUN: cmp %t %t1

# EXISTING: rpath 'ABCD' would create a duplicate load command

## Duplicate RPath entries:
# RUN: not llvm-install-name-tool -rpath DDD1/. @exec_d/. \
# RUN:                            -rpath @exec_d/. DDD2/. %t 2>&1 | \
# RUN:   FileCheck %s --check-prefix=DUPLICATE
# RUN: cmp %t %t1

# DUPLICATE: cannot specify both -rpath 'DDD1/.' '@exec_d/.' and -rpath '@exec_d/.' 'DDD2/.'

## Updating and deleting RPath at the same time:
# RUN: not llvm-install-name-tool -rpath @executable_d/. DD/. \
# RUN:                            -delete_rpath @executable_d/. %t 2>&1 | \
# RUN:   FileCheck %s --check-prefix=COMBINED-DELETE
# RUN: cmp %t %t1

# COMBINED-DELETE: cannot specify both -delete_rpath '@executable_d/.' and -rpath '@executable_d/.' 'DD/.'

## Updating and adding RPath at the same time:
# RUN: not llvm-install-name-tool -rpath @executable_e/. EE/. \
# RUN:                            -add_rpath @executable_e/. %t 2>&1 | \
# RUN:   FileCheck %s --check-prefix=COMBINED-ADD
# RUN: cmp %t %t1

# COMBINED-ADD: cannot specify both -add_rpath '@executable_e/.' and -rpath '@executable_e/.' 'EE/.'

## Missing an RPath argument:
# RUN: not llvm-install-name-tool %t -rpath @executable_e/. 2>&1 | \
# RUN:   FileCheck %s --check-prefix=MISSING
# RUN: cmp %t %t1

## Missing both RPath arguments:
# RUN: not llvm-install-name-tool %t -rpath 2>&1 | \
# RUN:   FileCheck %s --check-prefix=MISSING
# RUN: cmp %t %t1

# MISSING: missing argument to -rpath option
