2009-02-09Start processing template-ids as types when the template-name refersDouglas Gregor
to a class template. For example, the template-id 'vector<int>' now has a nice, sugary type in the type system. What we can do now: - Parse template-ids like 'vector<int>' (where 'vector' names a class template) and form proper types for them in the type system. - Parse icky template-ids like 'A<5>' and 'A<(5 > 0)>' properly, using (sadly) a bool in the parser to tell it whether '>' should be treated as an operator or not. This is a baby-step, with major problems and limitations: - There are currently two ways that we handle template arguments (whether they are types or expressions). These will be merged, and, most likely, TemplateArg will disappear. - We don't have any notion of the declaration of class template specializations or of template instantiations, so all template-ids are fancy names for 'int' :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64153 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-07Set load/store alignment when doing ABI coercions.Daniel Dunbar
- Currently, this is producing poor code, but we prefer correctness to performance for now.
