| ## 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 |

| ## 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 |
