## 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 -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={{.}}

## Generate XCOFF shared object file.
