## Test the "--export-symbols" option.
## The option merges all the output of input files, sorts and prints out unique symbols from the input files.

# RUN: yaml2obj --docnum=1 -DFLAG=0x0002 %s -o %t1.o
# RUN: yaml2obj --docnum=2 -DFLAG=0x0002 %s -o %t2.o
# RUN: yaml2obj --docnum=2 -DFLAG=0x0002 -DSECT=26 %s -o %t2_invalid.o

## Test the following cases:
## Do not export global symbols beginning with "__sinit" , "__sterm" , "." , "(". or regular expression "^__[0-9]+__".
## Do not export hidden and internal symbols.
## Remove name prefixes of global symbols beginning with "__tf1" and "__tf9".
# RUN: llvm-nm --export-symbols %t1.o | FileCheck %s --check-prefixes=COMMON,WEAK,RSRC --implicit-check-not={{.}}

## Show that weak symbols are not exported when using the "--no-weak" option.
# RUN: llvm-nm --export-symbols --no-weak %t1.o | FileCheck --check-prefixes=COMMON,RSRC  %s --implicit-check-not={{.}}

## Show that only unique symbols (with a different name or visibility) are exported.
## RUN: llvm-nm --export-symbols %t1.o %t2.o | FileCheck --check-prefixes=COMMON,WEAK,OBJ2,RSRC %s --implicit-check-not={{.}}

## Show that __rsrc symbols are not exported when using the "--no-rsrc" option.
# RUN: llvm-nm --export-symbols --no-rsrc %t1.o  | FileCheck --check-prefixes=COMMON,WEAK %s --implicit-check-not={{.}}

# COMMON:      023__
# COMMON-NEXT: __023
# COMMON-NEXT: __02er02__
# COMMON-NEXT: ____
# RSRC-NEXT:   __rsrc
# COMMON-NEXT: __rsrc export
# COMMON-NEXT: __tf2value
# COMMON-NEXT: export_protected_var export
# COMMON-NEXT: export_protected_var protected
# OBJ2-NEXT:   export_var_in_sec_obj export
# COMMON-NEXT: protected_var protected
# OBJ2-NEXT:   protected_var_in_sec_obj protected
# COMMON-NEXT: tf1value
# COMMON-NEXT: tf9value
# OBJ2-NEXT:   var1_in_sec_obj
# WEAK-NEXT:   weak_func

## Test the behavior of the symbol reference section.
# RUN: llvm-nm --export-symbols --no-rsrc %t2_invalid.o 2>&1 | \
# RUN:   FileCheck -DFILE=%t2_invalid.o --check-prefixes=INVALID %s

# INVALID:      llvm-nm{{(\.exe)?}}: warning: [[FILE]]: for symbol with index 8: the section index (26) is invalid
# INVALID-NEXT: export_protected_var export
# INVALID-NEXT: export_protected_var protected
# INVALID-NEXT: protected_var_in_sec_obj protected
# INVALID-NEXT: var1_in_sec_obj

## Show that symbols in shared object files are not exported.
## Generate XCOFF shared object file.
# RUN: yaml2obj -DFLAG=0x2000 --docnum=2 %s -o %t_shared.o
# RUN: llvm-nm --export-symbols %t_shared.o | count 0

## Test that llvm-nm ignores AIX linker import files when using --export-symbols. These start with "#!".
# RUN: echo -e "#!\n bar\n foo " > %t_imp.txt
# RUN: llvm-nm --export-symbols %t_imp.txt 2>&1 | count 0
