## Test that yaml2obj automatically assigns sh_addr to allocatable sections for ET_EXEC/ET_DYN files.

# RUN: yaml2obj %s -o %t.so -D TYPE=ET_DYN
# RUN: llvm-readelf --sections %t.so | FileCheck %s --check-prefix=EXE-DSO

# RUN: yaml2obj %s -o %t -D TYPE=ET_EXEC
# RUN: llvm-readelf --sections %t | FileCheck %s --check-prefix=EXE-DSO

# RUN: yaml2obj %s -o %t.o -D TYPE=ET_REL
# RUN: llvm-readelf --sections %t.o | FileCheck %s --check-prefix=REL

## We assign virtual addresses to allocatable sections automatically for executables and shared libraries.
