## 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
# DWARF-DEFAULT: String dump of section '.debug_str':
# DWARF-DEFAULT-NEXT: [ 0] a
# DWARF-DEFAULT-NEXT: [ 2] b
# DWARF-DEFAULT-NEXT: [ 4] c
## Check the default sh_type, sh_entsize, sh_info, sh_flags and sh_addralign of the
## .debug_str section header.
# RUN: llvm-readelf -S %t1.o | FileCheck -DSIZE=000006 %s --check-prefix=SHDRS-DEFAULT
# SHDRS-DEFAULT: Name Type Address Off Size ES Flg Lk Inf Al
# SHDRS-DEFAULT: .debug_str PROGBITS 0000000000000000 000040 [[SIZE]] 01 MS 0 0 1

## b) Generate the .debug_str section from the raw section content.
# RUN: yaml2obj --docnum=2 %s -o %t2.o
# RUN: llvm-readelf --string-dump=.debug_str %t2.o | FileCheck %s --check-prefix=DWARF-DEFAULT
# RUN: llvm-readelf -S %t2.o | FileCheck %s --check-prefix=SHDRS

## c) Generate the .debug_str section when the "Size" is specified.
# RUN: yaml2obj --docnum=3 %s -o %t3.o
# RUN: llvm-readelf -S %t3.o | FileCheck %s --check-prefix=SIZE
# RUN: llvm-readelf --hex-dump=.debug_str %t3.o | FileCheck %s --check-prefix=SIZE-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
# ERROR: yaml2obj: error: cannot specify section '.debug_str' contents in the 'DWARF' entry and the 'Content' or 'Size' in the 'Sections' entry at the same time

## f) Test that all the properties can be overridden by the section header when
## the "debug_str" entry doesn't exist.
# RUN: yaml2obj --docnum=6 %s -o %t6.o
