Added support for persistent types to the
expression parser. You can use a persistent
type like this:
(lldb) expr struct $foo { int a; int b; };
(lldb) struct $foo i; i.a = 2; i.b = 3; i
($foo) $0 = {
(int) a = 2
(int) b = 3
}
typedefs work similarly.
This patch affects the following files:
test/expression_command/persistent_types/*
A test case for persistent types,
in particular structs and typedefs.
ClangForward.h
Added TypeDecl, needed to declare some
functions in ASTResultSynthesizer.h
ClangPersistentVariables.[h,cpp]
Added a list of persistent types to the
persistent variable store.
ASTResultSynthesizer.[h,cpp]
Made the AST result synthesizer iterate
across TypeDecls in the expression, and
record any persistent types found. Also
made a minor documentation fix.
ClangUserExpression.[h,cpp]
Extended the user expression class to
keep the state needed to report the
persistent variable store for the target
to the AST result synthesizers.
Also introduced a new error code for
expressions that executed normally but
did not return a result.
CommandObjectExpression.cpp
Improved output for expressions (like
declarations of new persistent types) that
don't return a result. This is no longer
treated as an error.
