Bug ID: 28675
Summary: whitespace in DWARF template naming confuses
libabigail.
Product: libabigail
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: default
Assignee: dodji at redhat dot com
Reporter: woodard at redhat dot com
CC: libabigail at sourceware dot org
Target Milestone: ---
Comparing gcc built libabigail.so.0 to llvm built libabigail.so.0 one of the
commonly reported differences is like this:
[C] 'method const std::vector<abigail::comparison::diff*,
std::allocator<abigail::comparison::diff*> >&
abigail::comparison::corpus_diff::children_nodes() const' at
abg-comparison.h:2325:1 has some indirect sub-type changes:
return type changed:
in referenced type 'const std::vector<abigail::comparison::diff*,
std::allocator<abigail::comparison::diff*> >':
'const std::vector<abigail::comparison::diff*,
std::allocator<abigail::comparison::diff*> >' changed to 'const
std::vector<abigail::comparison::diff *,
std::allocator<abigail::comparison::diff *> >'
The difference is nothing other than white space:
const std::vector<abigail::comparison::diff*,
std::allocator<abigail::comparison::diff*> >
const std::vector<abigail::comparison::diff *,
std::allocator<abigail::comparison::diff *> >
clang puts a space between typename and the * while GCC does not.
This should be a special case that is handled by libabigail. It is not an
actual ABI difference.
