Eric Christopher df02b36a2c Change location information for synthesized properties to be at the
property file/line rather than the @synthesize file/line. Avoids
some nasty confusing-ness with conflating the file from the scope
and the line from the original declaration.

Update a couple of testcases accordingly since I had to change
that we actually use the passed in location in EmitFunctionStart.

Greg Clayton 219cf31f7d <rdar://problem/11082392>
Fixed an issue that could cause circular type parsing that will assert and kill LLDB.

Prior to this fix the DWARF parser would always create class types and not start their definitions (for both C++ and ObjC classes) until we were asked to complete the class later. When we had cases like:

class A
{
    class B
    {
    };
};

We would alway try to complete A before specifying "A" as the decl context for B. Turns out we can just start the definition and still not complete the class since we can check the TagDecl::isCompleteDefinition() function. This only works for C++ types. This means we will not be pulling in the full definition of parent classes all the time and should help with our memory consumption and also reduce the amount of debug info we have to parse.

I also reduced redundant code that was checking in a lldb::clang_type_t was a possible C++ dynamic type since it was still completing the type, just to see if it was dynamic. This was fixed in another function that was checking for a type being dynamic as an ObjC or a C++ type, but there was dedicated fucntion for C++ that we missed.

Bill Wendling 82b87f19e2 The UTF16 string referenced by a CFString should go into the __TEXT,__ustring
section. A 'normal' string will go into the __TEXT,__const section, but this
isn't good for UTF16 strings. The __ustring section allows for coalescing, among
other niceties (such as allowing the linker to easily split up strings).

Instead of outputting the UTF16 string as a series of bytes, output it as a
series of shorts. The back-end will then nicely place the UTF16 string into the
correct section, because it's a mensch.

Argyrios Kyrtzidis ab468b0381 Add info to ObjCPropertyRefExpr to indicate whether the dot syntax property
reference is going to message the setter, the getter, or both.

Having this info on the ObjCPropertyRefExpr node makes it easier for AST
clients (like libclang) to reason about the meaning of the property reference.

[AST/Sema]
-Use 2 bits (with a PointerIntPair) in ObjCPropertyRefExpr to record the above info
-Have ObjCPropertyOpBuilder set the info appropriately.

[libclang]
-When there is an implicit property reference (property syntax using methods)
have clang_getCursorReferenced return a cursor for the method. If the property
reference is going to result in messaging both the getter and the setter choose
to return a cursor for the setter because it is less obvious from source inspection
that the setter is getting called.

The general idea has the seal of approval by John.

Bill Wendling 9f829f1cc4 If we have a VLA that has a "use" in a metadata node that's then used
here but it has no other uses, then we have a problem. E.g.,

  int foo (const int *x) {
    char a[*x];
    return 0;
  }

If we assign 'a' a vreg and fast isel later on has to use the selection
DAG isel, it will want to copy the value to the vreg. However, there are
no uses, which goes counter to what selection DAG isel expects.

Jakob Stoklund Olesen d8af9a5ee1 Invalidate liveness in ARMConstantIslandPass.
This pass splits basic blocks to insert constant islands, and it

Jakob Stoklund Olesen 2f2897372a Prefer even-odd D-register pairs.
We are sometimes allocatinog from the DPair register class which
contains odd-even pairs in addition to the Q registers.

Place the Q registers first in the DPair allocation order as they can be
copied with a single instruction. The odd-even pairs should only be
allocated as a last resort.

Jakob Stoklund Olesen caa6bd273f Handle register copies for the new ARM register classes.
ARM recently gained DPair, DTriple, and DQuad register classes.
Update copyPhysReg() to handle copies in these register classes.

No test case, it is difficult to make the register allocator emit the
odd copies reliably. The missing DPair copy caused a failure on
partialsums in the nightly test suite.

Enrico Granata d50f18b1a0 Part 1 of a series of fixes meant to improve reliability and increase ease of bug fixing for data formatter issues.
We are introducing a new Logger class on the Python side. This has the same purpose, but is unrelated, to the C++ logging facility
The Pythonic logging can be enabled by using the following scripting commands:
(lldb) script Logger._lldb_formatters_debug_level = {0,1,2,...}
0 = no logging
1 = do log
2 = flush after logging each line - slower but safer
3 or more = each time a Logger is constructed, log the function that has created it
more log levels may be added, each one being more log-active than the previous
by default, the log output will come out on your screen, to direct it to a file:
(lldb) script Logger._lldb_formatters_debug_filename = 'filename'
that will make the output go to the file - set to None to disable the file output and get screen logging back
Logging has been enabled for the C++ STL formatters and for Cocoa class NSData - more logging will follow


synthetic children providers for classes list and map (both libstdcpp and libcxx) now have internal capping for safety reasons
this will fix crashers where a malformed list or map would not ever meet our termination conditions

to set the cap to a different value:

(lldb) script {gnu_libstdcpp|libcxx}.{map|list}_capping_size = new_cap (by default, it is 255)

you can optionally disable the loop detection algorithm for lists

(lldb) script {gnu_libstdcpp|libcxx}.list_uses_loop_detector = False
