52f792329be5db8e38961350589e97e8f2823acd 12-Jul-2013 Greg Clayton <gclayton@apple.com> Huge change to clean up types.

A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.

This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

a8b56238ce138e70433a0ce0b4218c9257beae38 19-Jun-2013 Greg Clayton <gclayton@apple.com> Added the ability to get a list of types from a SBModule or SBCompileUnit. Sebastien Metrot wanted this, and sent a hollowed out patch. I filled in the blanks and did the low level implementation. The new functions are:

//------------------------------------------------------------------
/// Get all types matching \a type_mask from debug info in this
/// module.
///
/// @param[in] type_mask
/// A bitfield that consists of one or more bits logically OR'ed
/// together from the lldb::TypeClass enumeration. This allows
/// you to request only structure types, or only class, struct
/// and union types. Passing in lldb::eTypeClassAny will return
/// all types found in the debug information for this module.
///
/// @return
/// A list of types in this module that match \a type_mask
//------------------------------------------------------------------
lldb::SBTypeList
SBModule::GetTypes (uint32_t type_mask)


//------------------------------------------------------------------
/// Get all types matching \a type_mask from debug info in this
/// compile unit.
///
/// @param[in] type_mask
/// A bitfield that consists of one or more bits logically OR'ed
/// together from the lldb::TypeClass enumeration. This allows
/// you to request only structure types, or only class, struct
/// and union types. Passing in lldb::eTypeClassAny will return
/// all types found in the debug information for this compile
/// unit.
///
/// @return
/// A list of types in this compile unit that match \a type_mask
//------------------------------------------------------------------
lldb::SBTypeList
SBCompileUnit::GetTypes (uint32_t type_mask = lldb::eTypeClassAny);

This lets you request types by filling out a mask that contains one or more bits from the lldb::TypeClass enumerations, so you can only get the types you really want.

<rdar://problem/13594769>

Main changes in this patch include:
- cleanup plug-in interface and use ConstStrings for plug-in names
- Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp
- Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging

The plug-in interface changes:

Modified the lldb_private::PluginInterface class that all plug-ins inherit from:

Changed:

virtual const char * GetPluginName() = 0;

To:

virtual ConstString GetPluginName() = 0;

Removed:

virtual const char * GetShortPluginName() = 0;

- Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names.
- Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc.

Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file".
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()

Cleaned up header includes a bit as well.

302d78c71902398ce1f422bd09216dd53a6abb88 10-Feb-2012 Sean Callanan <scallanan@apple.com> Extended function lookup to allow the user to
indicate whether inline functions are desired.
This allows the expression parser, for instance,
to filter out inlined functions when looking for
functions it can call.

16d2187c0c3992f22e9cb011f863dc0fe35e3cde 03-Dec-2011 Greg Clayton <gclayton@apple.com> Added the ability for clients to grab a set of symbol table indexes and then
add them to a fast lookup map. lldb_private::Symtab now export the following
public typedefs:

namespace lldb_private {

class Symtab {
typedef std::vector<uint32_t> IndexCollection;
typedef UniqueCStringMap<uint32_t> NameToIndexMap;
};
}

Clients can then find symbols by name and or type and end up with a
Symtab::IndexCollection that is filled with indexes. These indexes can then
be put into a name to index lookup map and control if the mangled and
demangled names get added to the map:

bool add_demangled = true;
bool add_mangled = true;
Symtab::NameToIndexMap name_to_index;
symtab->AppendSymbolNamesToMap (indexes, add_demangled, add_mangled, name_to_index).

This can be repeated as many times as needed to get a lookup table that
you are happy with, and then this can be sorted:

name_to_index.Sort();

Now name lookups can be done using a subset of the symbols you extracted from
the symbol table. This is currently being used to extract objective C types
from object files when there is no debug info in SymbolFileSymtab.

Cleaned up how the objective C types were being vended to be more efficient
and fixed some errors in the regular expression that was being used.

d0b7cfa22722fdaf4111a61d6eeb02a587710e16 03-Dec-2011 Sean Callanan <scallanan@apple.com> Testcase fixes with the new symbol lookup code for
Objective-C, making symbol lookups for various raw
Objective-C symbols work correctly. The IR interpreter
makes these lookups because Clang has emitted raw
symbol references for ivars and classes.

Also improved performance in SymbolFiles, caching the
result of asking for SymbolFile abilities.

99e2c554061d9356ab3314486cb12c160b261ba2 02-Dec-2011 Sean Callanan <scallanan@apple.com> Modified the Objective-C type map in SymbolFileSymtab
to use ConstStrings. The const char*s were assumed to
be from ConstStrings before, but since storing a full-on
ConstString is no more expensive than storing a const
char* it makes better sense to enforce uniqueness with
the type checker.

Objective-C symbols. The methods aren't used yet if
there is a competing definition in the DWARF; I will
resolve that next.

673f3dbea64b116166dfa668006cdc84224a27c0 30-Nov-2011 Sean Callanan <scallanan@apple.com> Added support to the Objective-C language runtime
to find Objective-C class types by looking in the
symbol tables for the individual object files.

I did this as follows:

- I added code to SymbolFileSymtab that vends
Clang types for symbols matching the pattern
"_OBJC_CLASS_$_NSMyClassName," making them
appear as Objective-C classes. This only occurs
in modules that do not have debug information,
since otherwise SymbolFileDWARF would be in
charge of looking up types.

- I made a new SymbolVendor subclass for the
Apple Objective-C runtime that is in charge of
making global lookups of Objective-C types. It
currently just sends out type lookup requests to
the appropriate SymbolFiles, but in the future we
will probably extend it to query the runtime more
completely.

I also modified a testcase whose behavior is changed
by the fact that we now actually return an Objective-C
type for __NSCFString.

down through Module and SymbolVendor into SymbolFile.
Added checks to SymbolFileDWARF that restrict symbol
searches when a namespace is passed in.

e4b9c1fb338ee1ada72e6a3c198afb342d68c5c1 08-Mar-2011 Greg Clayton <gclayton@apple.com> LLDB now has "Platform" plug-ins. Platform plug-ins are plug-ins that provide
an interface to a local or remote debugging platform. By default each host OS
that supports LLDB should be registering a "default" platform that will be
used unless a new platform is selected. Platforms are responsible for things
such as:
- getting process information by name or by processs ID
- finding platform files. This is useful for remote debugging where there is
an SDK with files that might already or need to be cached for debug access.
- getting a list of platform supported architectures in the exact order they
should be selected. This helps the native x86 platform on MacOSX select the
correct x86_64/i386 slice from universal binaries.
- Connect to remote platforms for remote debugging
- Resolving an executable including finding an executable inside platform
specific bundles (macosx uses .app bundles that contain files) and also
selecting the appropriate slice of universal files for a given platform.

So by default there is always a local platform, but remote platforms can be
connected to. I will soon be adding a new "platform" command that will support
the following commands:
(lldb) platform connect --name machine1 macosx connect://host:port
Connected to "machine1" platform.
(lldb) platform disconnect macosx

This allows LLDB to be well setup to do remote debugging and also once
connected process listing and finding for things like:
(lldb) process attach --name x<TAB>

The currently selected platform plug-in can now auto complete any available
processes that start with "x". The responsibilities for the platform plug-in
will soon grow and expand.

6916e358c9725b75ed91f31236c147f26c9af10e 13-Nov-2010 Greg Clayton <gclayton@apple.com> Modified the lldb_private::Type clang type resolving code to handle three
cases when getting the clang type:
- need only a forward declaration
- need a clang type that can be used for layout (members and args/return types)
- need a full clang type

This allows us to partially parse the clang types and be as lazy as possible.
The first case is when we just need to declare a type and we will complete it
later. The forward declaration happens only for class/union/structs and enums.
The layout type allows us to resolve the full clang type _except_ if we have
any modifiers on a pointer or reference (both R and L value). In this case
when we are adding members or function args or return types, we only need to
know how the type will be laid out and we can defer completing the pointee
type until we later need it. The last type means we need a full definition for
the clang type.

Did some renaming of some enumerations to get rid of the old "DC" prefix (which
stands for DebugCore which is no longer around).

Modified the clang namespace support to be almost ready to be fed to the
expression parser. I made a new ClangNamespaceDecl class that can carry around
the AST and the namespace decl so we can copy it into the expression AST. I
modified the symbol vendor and symbol file plug-ins to use this new class.

d7cb26e87841731c6452a9f2e997ed0f9c92625c 11-Nov-2010 Greg Clayton <gclayton@apple.com> Added initial support to the lldb_private::SymbolFile for finding
namespaces by name given an optional symbol context. I might end up
dressing up the "clang::NamespaceDecl" into a lldb_private::Namespace
class if we need to do more than is currenlty required of namespaces.
Currently we only need to be able to lookup a namespace by name when
parsing expressions, so I kept it simple for now. The idea here is
even though we are passing around a "clang::NamespaceDecl *", that
we always have it be an opaque pointer (it is forward declared inside
of "lldb/Core/ClangForward.h") and we only use clang::NamespaceDecl
implementations inside of ClangASTContext, or ClangASTType when we need
to extract information from the namespace decl object.



git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@118737 91177308-0d34-0410-b5e6-96231b3b80d8

462d4147f3bb9141bf62d904f58a623db00669df 29-Sep-2010 Greg Clayton <gclayton@apple.com> Fixed the forward declaration issue that was present in the DWARF parser after
adding methods to C++ and objective C classes. In order to make methods, we
need the function prototype which means we need the arguments. Parsing these
could cause a circular reference that caused an assertion.

Added a new typedef for the clang opaque types which are just void pointers:
lldb::clang_type_t. This appears in lldb-types.h.

This was fixed by enabling struct, union, class, and enum types to only get
a forward declaration when we make the clang opaque qual type for these
types. When they need to actually be resolved, lldb_private::Type will call
a new function in the SymbolFile protocol to resolve a clang type when it is
not fully defined (clang::TagDecl::getDefinition() returns NULL). This allows
us to be a lot more lazy when parsing clang types and keeps down the amount
of data that gets parsed into the ASTContext for each module.

Getting the clang type from a "lldb_private::Type" object now takes a boolean
that indicates if a forward declaration is ok:

clang_type_t lldb_private::Type::GetClangType (bool forward_decl_is_ok);

So function prototypes that define parameters that are "const T&" can now just
parse the forward declaration for type 'T' and we avoid circular references in
the type system.

960d6a40711f05effe6fcc5b66f0952450f79ea2 03-Aug-2010 Greg Clayton <gclayton@apple.com> Added support for objective C built-in types: id, Class, and SEL. This
involved watching for the objective C built-in types in DWARF and making sure
when we convert the DWARF types into clang types that we use the appropriate
ASTContext types.

Added a way to find and dump types in lldb (something equivalent to gdb's
"ptype" command):

image lookup --type <TYPENAME>

This only works for looking up types by name and won't work with variables.
It also currently dumps out verbose internal information. I will modify it
to dump more appropriate user level info in my next submission.

Hookup up the "FindTypes()" functions in the SymbolFile and SymbolVendor so
we can lookup types by name in one or more images.

Fixed "image lookup --address <ADDRESS>" to be able to correctly show all
symbol context information, but it will only show this extra information when
the new "--verbose" flag is used.

Updated to latest LLVM to get a few needed fixes.

12bec71b323dc520f0e985a86e09c4712559e115 28-Jun-2010 Greg Clayton <gclayton@apple.com> Added function name types to allow us to set breakpoints by name more
intelligently. The four name types we currently have are:

eFunctionNameTypeFull = (1 << 1), // The function name.
// For C this is the same as just the name of the function
// For C++ this is the demangled version of the mangled name.
// For ObjC this is the full function signature with the + or
// - and the square brackets and the class and selector
eFunctionNameTypeBase = (1 << 2), // The function name only, no namespaces or arguments and no class
// methods or selectors will be searched.
eFunctionNameTypeMethod = (1 << 3), // Find function by method name (C++) with no namespace or arguments
eFunctionNameTypeSelector = (1 << 4) // Find function by selector name (ObjC) names


this allows much more flexibility when setting breakoints:

(lldb) breakpoint set --name main --basename
(lldb) breakpoint set --name main --fullname
(lldb) breakpoint set --name main --method
(lldb) breakpoint set --name main --selector

The default:

(lldb) breakpoint set --name main

will inspect the name "main" and look for any parens, or if the name starts
with "-[" or "+[" and if any are found then a full name search will happen.
Else a basename search will be the default.

Fixed some command option structures so not all options are required when they
shouldn't be.

Cleaned up the breakpoint output summary.

Made the "image lookup --address <addr>" output much more verbose so it shows
all the important symbol context results. Added a GetDescription method to
many of the SymbolContext objects for the more verbose output.
