## 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
