## Check how obj2yaml dumps the SHT_LLVM_ADDRSIG section.

|
|
|

|
|
## Check that when possible obj2yaml tries to produce the "Name" tag when
|
||
|
|
## dumping entries of the SHT_LLVM_ADDRSIG section. It falls back to producing
|
||
|
|
## the "Index" tag when it can't match a symbol index with a symbol table entry.
