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.

to increased calls to SourceManager::getFileID. (rdar://9992664)
Use a slightly different approach that is more efficient both in terms of speed
(no extra getFileID calls) and in SLocEntries reduction.
Comparing pre-r138129 and this patch we get:
For compiling SemaExpr.cpp reduction of SLocEntries by 26%.
For the boost enum library:
-SLocEntries -34% (note that this was -5% for r138129)
-Memory consumption -50%
-PCH size -31%
Reduced SLocEntries also benefit the hot function SourceManager::getFileID,
evident by the reduced "FileID scans".

incorrectly in the CFG, and also the static analyzer. This patch regresses the analyzer a bit, but
that needs to be followed up with a better solution.
Fixes <rdar://problem/10008112>.
llvm-svn: 138372
system flags an error when unlocking a lock which was not held, locking
the same lock twice, having a different lockset on each iteration of a
loop, or going out of scope while still holding a lock. In order to
successfully use the lockset, this patch also makes sure that attribute
arguments are attached correctly for later parsing.
This patch was also worked on by DeLesley Hutchins.
Note: This patch has been reviewed by Chandler Carruth and Jeffrey
Yasskin. Feel free to provide post-commit review comments for a
subsequent patch.

output on darwin so is hard coded there.
As a note this will need a little bit of refactoring in the class
hierarchy to separate it out for different verifiers based on input type.
Fixes rdar://8256258.

There is no non-writeback store multiple instruction in Thumb1, so
don't define one. As a result load multiple is the only instantiation of
the multiclass, so refactor that away entirely.
