Bug ID: 33760
Summary: LLDB's SBType's template functions don't work for
template parameter packs
Product: new-bugs
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: m...@kkaefer.com
CC: llvm-bugs@lists.llvm.org
Consider these two types and their instantiations:
template <class A, class B> class Foo {};
template <class...> class Bar {};
Foo<int, float> foo;
Bar<int, float> bar;
When inspecting types in LLDB, val.GetType().GetNumberOfTemplateArguments()
returns 2 for val `foo`, but it returns 0 for val `bar`. There doesn't seem to
be a way to access the template arguments programmatically through SBType.
Instead of return 0 for variadic templates, it should return the actual number
of template arguments, and GetTemplateArgumentType(I) should return the
corresponding SBType for the particular instantiation.
