## Check --skip-symbol functionality when changing symbol bindings.
# RUN: llvm-objcopy %t.o %t2.o --localize-hidden --skip-symbol=foo3
# RUN: llvm-readelf -s %t2.o | FileCheck %s --check-prefix=LH-SYM

# LH-SYM-DAG: GLOBAL HIDDEN 1 foo3
# LH-SYM-DAG: LOCAL HIDDEN 1 foo4
# LH-SYM-DAG: LOCAL HIDDEN 1 foo5
## Check --skip-symbols functionality when changing symbol bindings.
# RUN: llvm-objcopy %t.o %t1.o --localize-hidden --skip-symbols=%t.skip.regex --regex
# RUN: llvm-readelf -s %t1.o | FileCheck %s --check-prefix=LH-SYMS

## Check --skip-symbol functionality when changing symbol names.
# RUN: echo -e "foo1 bar1\nfoo2 bar2" > %t.renames.list

## Check --skip-symbols functionality when changing symbol names.
# RUN: llvm-objcopy %t.o %t3.o --redefine-syms=%t.renames.list \

## Check the functionality when using skip options multiple times.
# RUN: echo "foo3" > %t.symbol0.list

## Only foo5 is not skipped.
# BOTH-DAG: GLOBAL INTERNAL 1 foo5
## Check that using an invalid symbol name regex generates an error.
# RUN: echo '*.' > %t.symbols.regex
# RUN: not llvm-objcopy %t.o --skip-symbols=%t.symbols.regex --regex 2>&1 | \
# RUN: FileCheck %s --check-prefix=SYMBOL

# RUN: FileCheck %s --check-prefix=SYMBOL
# SYMBOL: error: cannot compile regular expression '*.': repetition-operator operand invalid
## Check passing an invalid filename generates an error.
# RUN: not llvm-objcopy %t.o --skip-symbols=no_file 2>&1 | \
# RUN: FileCheck %s --check-prefix=FILE -DMSG=%errc_ENOENT
# FILE: error: 'no_file': [[MSG]]
