Fixed a broken test suite test after recent editline merges.

The problem is that editline currently is trying to be smart when we paste things into a terminal window. It detects that input is pending and multi-line input is accepted as long as there is anything pending.

So if you open lldb and paste the text between the quotes:

"command regex carp
s/^$/help/

carp
"

We still still be stuck in the "command regex" multi-line input reader as it will have all three lines:

"s/^$/help/

carp
"

The true fix for this is something Kate Stone will soon work on:

- multi-line input readers must opt into this paste/pending input feature ("expr" will opt into it, all other commands won't)
- If we are in a multi-line input reader that requests this and stuff is pasted, then it will do what it does today
- if we start in a IOHandler that doesn't need/want pending input and text is pasted, and we transistion to a IOHandler that does want this functionality, then disable the pending input. Example text would be:

"frame variable
thread backtrace
expr
for (int i=0;i<10;++i)
  (int)printf("i = %i\n", i);

frame select 0
"

When we push the expression multi-line reader we would disable the pending input because we had pending input _before_ we entered "expr".

If we did this first:

(lldb) expr

Then we pasted:

"void foo()
{
}

void bar()
{
}
"

Then we would allow the pending input to not look for an empty line to terminate the expression. We filed radar 19008425 to track fixing this issue.

a function body inside an expression that contained an earlier
block literal with non-trivial captures.  That's actually
a lot less likely than you'd think, though, because it has
to be a real function declaration, not just another block.
Mixed block/lambda code would work, as would a template
instantiation or a local class definition.

The code works correctly if the assertion is disabled.

Make DiagnosticsEngine::takeClient return std::unique_ptr<>

Summary:
Make DiagnosticsEngine::takeClient return std::unique_ptr<>. Updated
callers to store conditional ownership using a pair of pointer and unique_ptr
instead of a pointer + bool. Updated code that temporarily registers clients to
use the non-owning registration (+ removed extra calls to takeClient).

9 years agoHandle use of default member initializers before end of outermost class
Reid Kleckner [Mon, 17 Nov 2014 23:36:45 +0000 (23:36 +0000)]
Handle use of default member initializers before end of outermost class

Specifically, when we have this situation:
  struct A {
    template <typename T> struct B {
      int m1 = sizeof(A);
    };
    B<int> m2;
  };

We can't parse m1's initializer eagerly because we need A to be
complete.  Therefore we wait until the end of A's class scope to parse
it. However, we can trigger instantiation of B before the end of A,
which will attempt to instantiate the field decls eagerly, and it would
build a bad field decl instantiation that said it had an initializer but
actually lacked one.

Fixed by deferring instantiation of default member initializers until
they are needed during constructor analysis. This addresses a long
standing FIXME in the code.

Fixes PR19195.

9 years agoIR: Simplify uniquing for MDNode
Duncan P. N. Exon Smith [Mon, 17 Nov 2014 23:28:21 +0000 (23:28 +0000)]
IR: Simplify uniquing for MDNode

Change uniquing from a `FoldingSet` to a `DenseSet` with custom
`DenseMapInfo`.  Unfortunately, this doesn't save any memory, since
`DenseSet<T>` is a simple wrapper for `DenseMap<T, char>`, but I'll come
back to fix that later.

I used the name `GenericDenseMapInfo` to the custom `DenseMapInfo` since
I'll be splitting `MDNode` into two classes soon: `MDNodeFwdDecl` for
temporaries, and `GenericMDNode` for everything else.

I also added a non-debug-info reduced version of a type-uniquing test
that started failing on an earlier draft of this patch.

Part of PR21532.
