## 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

# SHDRS: Name       Type     Address          Off    Size   ES Flg Lk Inf Al

## 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

# SIZE: .debug_str PROGBITS 0000000000000000 000040 000010 01 MS  0  0   0

#       SIZE-CONTENT: Hex dump of section '.debug_str':
#  SIZE-CONTENT-NEXT: 0x00000000 00000000 00000000 00000000 00000000 ................

## 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

## h) Test that if we try to initialize the .debug_str section with a "Type" with non-standard
## syntax, e.g., SHT_DYNAMIC, yaml2obj will treat it as a dynamic section and discard the
## content in the "DWARF" entry.

# RUN: yaml2obj --docnum=8 %s -o %t8.o
