## Test how we dump the .debug_str section.

## a) Test dumping a .debug_str section with a default section header.

# RUN: yaml2obj --docnum=1 %s | obj2yaml | \
# RUN:   FileCheck %s --check-prefix=BASIC --implicit-check-not='Name: .debug_str'

## b) Test dumping a .debug_str section whose section header properties are overridden.

## Override the sh_type field.
# RUN: yaml2obj --docnum=1 -DTYPE=STRTAB %s | obj2yaml | \
# RUN:   FileCheck %s --check-prefixes=BASIC,COMMON \
# RUN:     -DTYPE=STRTAB -DFLAGS="[ SHF_MERGE, SHF_STRINGS ]" -D#%x,ADDRALIGN=1

## Override the sh_flags field.
# RUN: yaml2obj --docnum=1 -DFLAGS=[SHF_ALLOC] %s | obj2yaml | \
# RUN:   FileCheck %s --check-prefixes=BASIC,COMMON \
# RUN:     -DTYPE=PROGBITS -DFLAGS="[ SHF_ALLOC ]" -D#%x,ADDRALIGN=1

## Override the sh_link field.
# RUN: yaml2obj --docnum=1 -DLINK=.sec %s | obj2yaml | \
# RUN:   FileCheck %s --check-prefixes=BASIC,COMMON,LINK \
# RUN:     -DTYPE=PROGBITS -DFLAGS="[ SHF_MERGE, SHF_STRINGS ]" -DLINK=.sec -D#%x,ADDRALIGN=1

## Override the sh_addr field.
# RUN: yaml2obj --docnum=1 -DADDRESS=0x2020 %s | obj2yaml | \
# RUN:   FileCheck %s --check-prefixes=BASIC,COMMON,ADDRESS \
# RUN:     -DTYPE=PROGBITS -DFLAGS="[ SHF_MERGE, SHF_STRINGS ]" -D#%x,ADDRALIGN=1 -D#%x,ADDRESS=0x2020

## Override the sh_addralign field.
# RUN: yaml2obj --docnum=1 -DADDRALIGN=3 %s | obj2yaml | \
# RUN:   FileCheck %s --check-prefixes=BASIC,COMMON \
# RUN:     -DTYPE=PROGBITS -DFLAGS="[ SHF_MERGE, SHF_STRINGS ]" -D#%x,ADDRALIGN=3

## Override the sh_entsize field (sh_entsize=3).
# RUN: yaml2obj --docnum=1 -DENTSIZE=3 %s | obj2yaml | \
# RUN:   FileCheck %s --check-prefixes=BASIC,COMMON,ENTSIZE \
# RUN:     -DTYPE=PROGBITS -DFLAGS="[ SHF_MERGE, SHF_STRINGS ]" -D#%x,ADDRALIGN=1 -D#%x,ENTSIZE=3

## Override the sh_entsize field (sh_entsize=0).
# RUN: yaml2obj --docnum=1 -DENTSIZE=0 %s | obj2yaml | \
# RUN:   FileCheck %s --check-prefixes=BASIC,COMMON,ENTSIZE \
# RUN:     -DTYPE=PROGBITS -DFLAGS="[ SHF_MERGE, SHF_STRINGS ]" -D#%x,ADDRALIGN=1 -D#%x,ENTSIZE=0

## Override the sh_info field.
# RUN: yaml2obj --docnum=1 -DINFO=3 %s | obj2yaml | \
# RUN:   FileCheck %s --check-prefixes=BASIC,COMMON,INFO \
# RUN:     -DTYPE=PROGBITS -DFLAGS="[ SHF_MERGE, SHF_STRINGS ]" -D#%x,INFO=3 -D#%x,ADDRALIGN=1 -D#%x,ENTSIZE=1

## c) Test dumping an empty .debug_str section.

# RUN: yaml2obj --docnum=2 %s | obj2yaml | FileCheck %s --check-prefix=EMPTY --implicit-check-not=Sections

## d) Test that yaml2obj stops parsing the .debug_str section if it encounters a
## string without a null terminator. The output uses a raw content section instead of
## the DWARF tag to represent the broken .debug_str section.

# RUN: yaml2obj --docnum=3 %s | obj2yaml | FileCheck %s --check-prefix=NO-TERMINATOR
