Manuel Klimek [Fri, 1 Feb 2013 13:41:35 +0000 (13:41 +0000)]
Re-design the convenience interfaces on MatchFinder.

First, this implements a match() method on MatchFinder; this allows us
to get rid of the findAll implementation, as findAll is really a special
case of recursive matchers on match.

Instead of findAll, provide a convenience function match() that lets
users iterate easily over the results instead of needing to implement
callbacks.

11 years agoRevamp of the basic layouting algorithm in clang-format.
Daniel Jasper [Fri, 1 Feb 2013 11:00:45 +0000 (11:00 +0000)]
Revamp of the basic layouting algorithm in clang-format.

In order to end up with good solutions, clang-format needs to try
"all" combinations of line breaks, evaluate them and select the
best one. Before, we have done this using a DFS with memoization
and cut-off conditions. However, this approach is very limited
as shown by the huge static initializer in the attachment of
llvm.org/PR14959.

Instead, this new implementation uses a variant of Dijkstra's
algorithm to do a prioritized BFS over the solution space.

Some numbers:
lib/Format/TokenAnnotator.cpp: 1.5s -> 0.15s
Attachment of PR14959: 10min+ (didn't finish) -> 10s

No functional changes intended.

Modified the expression parser's class wrapper to
support reporting "this" as a templated class.  The
expression parser wraps expressions in C++ methods
as methods with the signature

$__lldb_class::$__lldb_expr(...)

and previously responded to clang's queries about
$__lldb_class with the type of *this.  This didn't
work if *this was a ClassTemplateSpecializationDecl
because ClassTemplateSpecializationDecls can't be
the result of simple name queries.

Instead what we do now is respond that $__lldb_class
is a typedef and that the target of the typedef is
the (potentially templated) type of *this.  That is
much more robust.
