Subject: [PATCH] dwarf_loader: Don't stop processing after finding unsupported
|
||||
tag
|
||||
|
||||
After emitting a warning that a tag is not supported __die__process_tag
|
||||
was returning NULL, making die__process_unit think that the problem
|
||||
was insufficient memory.
|
||||
|
||||
Introduce a global variable 'unsupported_tag' and return it instead,
|
||||
that way die__process_unit can distinguish ENOMEM from unsupported tags.

||||
