## Test that yaml2obj emits .debug_str section.
## a) Generate the .debug_str section from the "DWARF" entry.
# RUN: yaml2obj --docnum=1 %s -o %t1.o
# RUN: llvm-readelf --string-dump=.debug_str %t1.o | FileCheck %s --check-prefix=DWARF-DEFAULT

## Check the default sh_type, sh_entsize, sh_info, sh_flags and sh_addralign of the
## .debug_str section header.

## b) Generate the .debug_str section from the raw section content.

## d) Test that yaml2obj emits an error message when both the "Size" and the
## "debug_str" entry are specified at the same time.
# RUN: not yaml2obj --docnum=4 %s -o %t4.o 2>&1 | FileCheck %s --check-prefix=ERROR
