top-of-tree. Removed all local patches and llvm.zip.
The intent is that fron now on top-of-tree will
always build against LLVM/Clang top-of-tree, and
that problems building will be resolved as they
occur. Stable release branches of LLDB can be
constructed as needed and linked to specific release
branches of LLVM/Clang.

sel_getName() calls are generated for all Objective-C
selectors before static literals are moved to the
static allocation. This prevents errors of the form

llvm-svn: 160887
to returned by expressions, by removing the
__cxa_atexit call that would normally cause these
objects to be destroyed. This also prevents many
errors of the form
Couldn't rewrite one of the arguments of a function call

llvm-svn: 160596
Improved the error message when we can find a function in the current program by printing the demangled name.
Also added the ability to create lldb_private::Mangled instances with a ConstString when we already have a ConstString for a mangled or demangled name. Also added the ability to call SetValue with a ConstString and also without a boolean to indicate if the string is mangled where we will now auto-detect if the string is mangled.

what libraries expect.
- Literals are now allocated at their preferred

ones, to its own constant pool. This reflects the fact
that the LLVM code generators for different targets move
floats to their constant pools under varying conditions,
and the JIT cannot (yet) be relied upon to relocate references to
its constant pool correctly.

doesn't return a result. If that expression can't
be run in the current context (for example, if it
uses a function and there is no running process)
then we used to try to destroy the nonexistent
result variable. We now only destroy the result
variable if we actually made one.
llvm-svn: 155455
LLVM/Clang. This brings in several fixes, including:
- Improvements in the Just-In-Time compiler's
allocation of memory: the JIT now allocates
memory in chunks of sections, improving its
ability to generate relocations. I have
revamped the RecordingMemoryManager to reflect
these changes, as well as to get the memory
allocation and data copying out fo the
ClangExpressionParser code. Jim Grosbach wrote
the updates to the JIT on the LLVM side.
- A new ExternalASTSource interface to allow LLDB to
report accurate structure layout information to
Clang. Previously we could only report the sizes
of fields, not their offsets. This meant that if
data structures included field alignment
directives, we could not communicate the necessary
alignment to Clang and accesses to the data would
fail. Now we can (and I have update the relevant
test case). Thanks to Doug Gregor for implementing
the Clang side of this fix.
- The way Objective-C interfaces are completed by
Clang has been made consistent with RecordDecls;
with help from Doug Gregor and Greg Clayton I have
ensured that this still works.
- I have eliminated all local LLVM and Clang patches,
committing the ones that are still relevant to LLVM
and Clang as needed.
I have tested the changes extensively locally, but
please let me know if they cause any trouble for you.
llvm-svn: 149775
an error along with its boolean result. The
expression parser reports this error if the
interpreter fails and the expression could not be
run in the target.
llvm-svn: 148870
the expression parser to locate instances where
dyn_cast<>() and isa<>() are used on types, and
replace them with getAs<>() as appropriate.
The difference is that dyn_cast<>() and isa<>()
are essentially LLVM/Clang's equivalent of RTTI
-- that is, they try to downcast the object and
return NULL if they cannot -- but getAs<>() can
traverse typedefs to perform a semantic cast.
llvm-svn: 146537
pointer to make the result of an expression. LLDB now
dumps the ivars of the Objective-C object and all of
its parents. This just required fixing a bug where we
didn't distinguish between Objective-C object pointers
and regular C-style pointers.
Also added a testcase to verify that this continues to
work.
llvm-svn: 146164
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.
llvm-svn: 145777
robust:
- Now a client can specify what kind of symbols
are needed; notably, this allows looking up
Objective-C class symbols specifically.
- In the class of symbols being looked up, if
one is non-NULL and others are NULL, LLDB now
prefers the non-NULL one.
llvm-svn: 145554
several patches. These patches fix a problem
where templated types were not being completed the
first time they were used, and fix a variety of
minor issues I discovered while fixing that problem.
One of the previous local patches was resolved in
the most recent Clang, so I removed it. The others
will be removed in due course.
llvm-svn: 144984
to allow variables in the persistent variable store to know
how to complete themselves from debug information. That
fixes a variety of bugs during dematerialization of
expression results and also makes persistent variable and
result variables ($foo, $4, ...) more useful.
I have also added logging improvements that make it much
easier to figure out how types are moving from place to
place, and made some checking a little more aggressive.
The commit includes patches to Clang which are currently being
integrated into Clang proper; once these fixes are in Clang
top-of-tree, these patches will be removed. The patches don't
fix API; rather, they fix some internal bugs in Clang's
ASTImporter that were exposed when LLDB was moving types from
place to place multiple times.
llvm-svn: 144969
types. First, I added handling for the memset intrinsic
in the IR, which is used to zero out the returned struct.
Second, I fixed the object-checking instrumentation
to objc_msgSend_stret, and generally tightened up how
the object-checking functions get inserted.
llvm-svn: 144741
correctly, and added a testcase to check that it works.
The main problem here is that Objective-C class method
selectors are external references stored in a special
data structure in the LLVM IR module for an expression.
I just had to extract them and ensure that the real
class object locations were properly resolved.

expected:
-
(lldb) expr struct { int a; int b; } $blah = { 10, 20 }

(lldb) expr $blah

(int) a = 10
(int) b = 20
}
-
Now the IRForTarget subsystem knows how to handle
static initializers of various composite types.
Also removed an unnecessary parameter from
ClangExpressionDeclMap::GetFunctionInfo.

of literal addresses. Also disabled special-cased

casts), substituting the IR interpreter.

to execute expressions even in the absence of a process.
This allows expressions to run in situations where the
target cannot run -- e.g., to perform calculations based
on type information, or to inspect a binary's static
data.
This modification touches the following files:
lldb-private-enumerations.h
Introduce a new enum specifying the policy for
processing an expression. Some expressions should
always be JITted, for example if they are functions
that will be used over and over again. Some
expressions should always be interpreted, for
example if the target is unsafe to run. For most,
it is acceptable to JIT them, but interpretation
is preferable when possible.
Target.[h,cpp]
Have EvaluateExpression now accept the new enum.
ClangExpressionDeclMap.[cpp,h]
Add support for the IR interpreter and also make
the ClangExpressionDeclMap more robust in the
absence of a process.
ClangFunction.[cpp,h]
Add support for the new enum.
IRInterpreter.[cpp,h]
New implementation.
ClangUserExpression.[cpp,h]
Add support for the new enum, and for running
expressions in the absence of a process.
ClangExpression.h
Remove references to the old DWARF-based method
of evaluating expressions, because it has been
superseded for now.
ClangUtilityFunction.[cpp,h]
Add support for the new enum.
ClangExpressionParser.[cpp,h]
Add support for the new enum, remove references
to DWARF, and add support for checking whether
the expression could be evaluated statically.
IRForTarget.[h,cpp]
Add support for the new enum, and add utility
functions to support the interpreter.
IRToDWARF.cpp
Removed
CommandObjectExpression.cpp
Remove references to the obsolete -i option.
Process.cpp
Modify calls to ClangUserExpression::Evaluate
to pass the correct enum (for dlopen/dlclose)
SBValue.cpp
Add support for the new enum.
SBFrame.cpp
Add support for he new enum.
BreakpointOptions.cpp
Add support for the new enum.
llvm-svn: 139772
of string literals ("hello"[2]). Also fixed a
problem in which empty string literals were not
being compiled correctly ((int)printf("") would
print garbage).
Added a testcase that covers both.
llvm-svn: 137247
expressions that used function pointers. The problem
was that IRForTarget previously only scanned the IR
for the expression for call instructions; if a function
was used in another context, it was ignored.
Now LLDB scans the Module for functions that are only
declared (not also defined -- so these are externals);
it then constructs function pointers for these
functions and substitutes them wherever the function
is used.
Also made some changes so that "expr main" works just
as well as "expr &main"; they end up being the same
code, but LLDB was generating the result variable in
different ways.
llvm-svn: 136928
caused functions that were cast as part of the
call to have that cast ignored once their
addresses were resolved.
Notably, in the case of objc_msgSend(), if
the function was cast from something returning
i8* to something returning i8, the expression
parser was discarding the cast as part of its
resolution. This caused crashes later on.
llvm-svn: 136648
treated as externals, causing problems when we
tried to look their locations up in the debug
info. For example:
expr char c[] = "foo"; c[0]
would terminate when trying to find c in the
debug information, despite the fact that c was
defined inside the expression.
llvm-svn: 136629
completes the support in the LLDB expression parser
for incomplete types. Clang now imports types
lazily, and we complete those types as necessary.
Changes include:
- ClangASTSource now supports three APIs which it
passes to ClangExpressionDeclMap. CompleteType
completes a TagDecl or an ObjCInterfaceDecl when
needed; FindExternalVisibleDecls finds named
entities that are visible in the expression's
scope; and FindExternalLexicalDecls performs a
(potentially restricted) search for entities
inside a lexical scope like a namespace. These
changes mean that entities in namespaces should
work normally.
- The SymbolFileDWARF code for searching a context
for a specific name is now more general, and can
search arbitrary contexts.
- We are continuing to adapt our calls into LLVM
from interfaces that take start and end iterators
when accepting multiple items to interfaces that
use ArrayRef.
- I have cleaned up some code, especially our use
of namespaces.
This change is neutral for our testsuite and greatly
improves correctness for large programs (like Clang)
with complicated type systems. It should also lay
the groundwork for improving the expression parser's
performance as we are lazier and lazier about
providing type information.
llvm-svn: 136555
Used hand merge to apply the diffs. I did not apply the diffs for FormatManager.h and
the diffs for memberwise initialization for ValueObject.cpp because they changed since.
I will ask my colleague to apply them later.
llvm-svn: 135508
Code cleanup:
- The Format Manager implementation is now split between two files: FormatClasses.{h|cpp} where the
actual formatter classes (ValueFormat, SummaryFormat, ...) are implemented and
FormatManager.{h|cpp} where the infrastructure classes (FormatNavigator, FormatManager, ...)
are contained. The wrapper code always remains in Debugger.{h|cpp}
- Several leftover fields, methods and comments from previous design choices have been removed
type category subcommands (enable, disable, delete) now can take a list of category names as input
- for type category enable, saying "enable A B C" is the same as saying
enable C
enable B
enable A
(the ordering is relevant in enabling categories, and it is expected that a user typing
enable A B C wants to look into category A, then into B, then into C and not the other
way round)
- for the other two commands, the order is not really relevant (however, the same inverted ordering
is used for consistency)
llvm-svn: 135494
pointers. Some of the spots are obviously initialized
later, but it's better just to NULL the pointers out
at initialization to make the code more robust when
exposed to later changes.
llvm-svn: 134670
virtual bool
ABI::StackUsesFrames () = 0;
Should return true if your ABI uses frames when doing stack backtraces. This
means a frame pointer is used that points to the previous stack frame in some
way or another.
virtual bool
ABI::CallFrameAddressIsValid (lldb::addr_t cfa) = 0;
Should take a look at a call frame address (CFA) which is just the stack
pointer value upon entry to a function. ABIs usually impose alignment
restrictions (4, 8 or 16 byte aligned), and zero is usually not allowed.
This function should return true if "cfa" is valid call frame address for
the ABI, and false otherwise. This is used by the generic stack frame unwinding
code to help determine when a stack ends.
virtual bool
ABI::CodeAddressIsValid (lldb::addr_t pc) = 0;
Validates a possible PC value and returns true if an opcode can be at "pc".
Some ABIs or architectures have fixed width instructions and must be aligned
to a 2 or 4 byte boundary. "pc" can be an opcode or a callable address which
means the load address might be decorated with extra bits (such as bit zero
to indicate a thumb function call for ARM targets), so take this into account
when returning true or false. The address should also be validated to ensure
it is a valid address for the address size of the inferior process. 32 bit
targets should make sure the address is less than UINT32_MAX.
Modified UnwindLLDB to use the new ABI functions to help it properly terminate
stacks.
Modified the mach-o function that extracts dependent files to not resolve the
path as the paths inside a binary might not match those on the current
host system.
llvm-svn: 132021
into the mainline LLDB codebase. MCJIT introduces
API improvements and better architectural support.
This commit adds a new subsystem, the
ProcessDataAllocator, which is responsible for
performing static data allocations on behalf of the
IR transformer. MCJIT currently does not support
the relocations required to store the constant pool
in the same allocation as the function body, so we
allocate a heap region separately and redirect
static data references from the expression to that
heap region in a new IR modification pass.
This patch also fixes bugs in the IR
transformations that were exposed by the transition
to the MCJIT. Finally, the patch also pulls in a
more recent revision of LLVM so that the MCJIT is
available for use.
llvm-svn: 131923
variables be evaluated statically.
Also fixed a bug that caused the results of
statically-evaluated expressions to be materialized
improperly.
This bug also removes some duplicate code.
llvm-svn: 131042
- Objective-C constant strings were being
NULL-terminated erroneously.
- Empty Objective-C constant strings were not
being generated correctly.
Also added the template for a test of these
fixes.
llvm-svn: 125314
by LLDB. Instead of being materialized into the input structure
passed to the expression, variables are left in place and pointers
to them are materialzied into the structure. Variables not resident
in memory (notably, registers) get temporary memory regions allocated
for them.
Persistent variables are the most complex part of this, because they
are made in various ways and there are different expectations about
their lifetime. Persistent variables now have flags indicating their
status and what the expectations for longevity are. They can be
marked as residing in target memory permanently -- this is the
default for result variables from expressions entered on the command
line and for explicitly declared persistent variables (but more on
that below). Other result variables have their memory freed.
Some major improvements resulting from this include being able to
properly take the address of variables, better and cleaner support
for functions that return references, and cleaner C++ support in
general. One problem that remains is the problem of explicitly
declared persistent variables; I have not yet implemented the code
that makes references to them into indirect references, so currently
materialization and dematerialization of these variables is broken.
llvm-svn: 123371
can avoid running the code in the target if the
expression's result is known and the expression
has no side effects.
Right now this feature is quite conservative in
its guess about side effects, and it only computes
integer results, but the machinery to make it more
sophisticated is there.
llvm-svn: 121952
access to the members of the Objective-C self object.
The approach we take is to generate the method as a
@category on top of the self object, and to pass the
"self" pointer to it. (_cmd is currently NULL.)
Most changes are in ClangExpressionDeclMap, but the
change that adds support to the ABIs to pass _cmd
touches a fair amount of code.
llvm-svn: 121722
wrongly as the target of a pointer rather than the
SEL pointer itself. This caused incorrect behavior
when dealing with Objective-C selector variables.
llvm-svn: 121048
expression logging.
Added some properties to the "objc" test. The expression parser can currently
display properties that are backed by the default functions "expr myStr.string"
will work. But it won't currently work when the property is backed by a
different function such as "expr myStr.date".
llvm-svn: 119103
every external variable reference in the module,
and returning a clean error (instead of letting
LLVM issue a fatal error) if the variable could
not be resolved.
llvm-svn: 118388
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.
llvm-svn: 118319
Changed all of our synthesized "___clang" functions, types and variables
that get used in expressions over to have a prefix of "$_lldb". Now when we
do name lookups we can easily switch off of the first '$' character to know
if we should look through only our internal (when first char is '$') stuff,
or when we should look through program variables, functions and types.
Converted all of the clang expression code over to using "const ConstString&"
values for names instead of "const char *" since there were many places that
were converting the "const char *" names into ConstString names and them
throwing them away. We now avoid making a lot of ConstString conversions and
benefit from the quick comparisons in a few extra spots.
Converted a lot of code from LLVM coding conventions into LLDB coding
conventions.
llvm-svn: 116634
to using Clang to get type sizes. This fixes a bug
where the type size for a double[2] was being wrongly
reported as 8 instead of 16 bytes, causing problems
for IRForTarget.
Also improved logging so that the next bug in this
area will be easier to find.
llvm-svn: 115208
- the guard variable for the static result
variable was being mistaken for the actual
result value, causing IRForTarget to fail
- LLVM builtins like memcpy were not being
properly resolved; now they are resolved
to the corresponding function in the target
llvm-svn: 114990
- Sema is now exported (and there was much rejoicing.)
- Storage classes are now centrally defined.
Also fixed some bugs that the new LLVM picked up.
llvm-svn: 114622
for C++ classes. Replaced it with a less hacky approach:
- If an expression is defined in the context of a
method of class A, then that expression is wrapped as
___clang_class::___clang_expr(void*) { ... }
instead of ___clang_expr(void*) { ... }.
- ___clang_class is resolved as the type of the target
of the "this" pointer in the method the expression
is defined in.
- When reporting the type of ___clang_class, a method
with the signature ___clang_expr(void*) is added to
that class, so that Clang doesn't complain about a
method being defined without a corresponding
declaration.
- Whenever the expression gets called, "this" gets
looked up, type-checked, and then passed in as the
first argument.
This required the following changes:
- The ABIs were changed to support passing of the "this"
pointer as part of trivial calls.
- ThreadPlanCallFunction and ClangFunction were changed
to support passing of an optional "this" pointer.
- ClangUserExpression was extended to perform the
wrapping described above.
- ClangASTSource was changed to revert the changes
required by the hack.
- ClangExpressionParser, IRForTarget, and
ClangExpressionDeclMap were changed to handle
different manglings of ___clang_expr flexibly. This
meant no longer searching for a function called
___clang_expr, but rather looking for a function whose
name *contains* ___clang_expr.
- ClangExpressionParser and ClangExpressionDeclMap now
remember whether "this" is required, and know how to
look it up as necessary.
A few inheritance bugs remain, and I'm trying to resolve
these. But it is now possible to use "this" as well as
refer implicitly to member variables, when in the proper
context.
llvm-svn: 114384
- If you put a semicolon at the end of an expression,
this no longer causes the expression parser to
error out. This was a two-part fix: first,
ClangExpressionDeclMap::Materialize now handles
an empty struct (such as when there is no return
value); second, ASTResultSynthesizer walks backward
from the end of the ASTs until it reaches something
that's not a NullStmt.
- ClangExpressionVariable now properly byte-swaps when
printing itself.
- ClangUtilityFunction now cleans up after itself when
it's done compiling itself.
- Utility functions can now use external functions just
like user expressions.
- If you end your expression with a statement that does
not return a value, the expression now runs correctly
anyway.
Also, added the beginnings of an Objective-C object
validator function, which is neither installed nor used
as yet.
llvm-svn: 113789
certain functions from being resolved correctly.
Some functions (particularly varargs functions)
are BitCast before being called, and the problem
was that a CallInst where getCalledValue()
returned a BitCast ConstantExpr was not being
relocated at all.
This problem should now be resolved for the case
of BitCast.
llvm-svn: 113396
expressions correctly. These produced a result
variable with an initializer but no store
instruction, and the store instruction was as
a result never rewritten to become a store to a
persistent variable.
Now if the result variable has an initializer
but is never used, we generate a (redundant)
store instruction for it, which is then later
rewritten into a (useful) store to the persistent
result variable.
llvm-svn: 113300
symbols with the same name and no debug information.
Also improved the way functions are called so we
don't automatically define them as variadic functions
in the IR.
llvm-svn: 113290
persistent variables were staying around too long.
This caused the following problem:
- A persistent result variable is created for the
result of an expression. The pointer to the
corresponding Decl is stored in the variable.
- The persistent variable is looked up during
struct generation (correctly) using its Decl.
- Another expression defines a new result variable
which happens to have a Decl in the same place
as the original result variable.
- The persistent variable is looked up during
struct generation using its Decl, but the old
result variable appears first in the list and
has the same Decl pointer.
The fix is to destroy parser-specific data when
it is no longer valid.
Also improved some logging as I diagnosed the
bug.
llvm-svn: 112540
The goal is to separate the parser's data from the data
belonging to the parser's clients. This allows clients
to use the parser to obtain (for example) a JIT compiled
function or some DWARF code, and then discard the parser
state.
Previously, parser state was held in ClangExpression and
used liberally by ClangFunction, which inherited from
ClangExpression. The main effects of this refactoring
are:
- reducing ClangExpression to an abstract class that
declares methods that any client must expose to the
expression parser,
- moving the code specific to implementing the "expr"
command from ClangExpression and
CommandObjectExpression into ClangUserExpression,
a new class,
- moving the common parser interaction code from
ClangExpression into ClangExpressionParser, a new
class, and
- making ClangFunction rely only on
ClangExpressionParser and not depend on the
internal implementation of ClangExpression.
Side effects include:
- the compiler interaction code has been factored
out of ClangFunction and is now in an AST pass
(ASTStructExtractor),
- the header file for ClangFunction is now fully
documented,
- several bugs that only popped up when Clang was
deallocated (which never happened, since the
lifetime of the compiler was essentially infinite)
are now fixed, and
- the developer-only "call" command has been
disabled.
I have tested the expr command and the Objective-C
step-into code, which use ClangUserExpression and
ClangFunction, respectively, and verified that they
work. Please let me know if you encounter bugs or
poor documentation.

expression parser. There shouldn't be four separate
classes encapsulating a variable.
ClangExpressionVariable is now meant to be the
container for all variable information. It has
several optional components that hold data for
different subsystems.
ClangPersistentVariable has been removed; we now
use ClangExpressionVariable instead.

expression. It is now possible to do things like this:
(lldb) expr int $i = 5; $i + 1
$0 = (int) 6
(lldb) expr $i + 3
$1 = (int) 8
(lldb) expr $1 + $0
$2 = (int) 14
As a bonus, this allowed us to move printing of
expression results into the ClangPersistentVariable
class. This code needs a bit of refactoring -- in
particular, ClangExpressionDeclMap has eaten one too
many bacteria and needs to undergo mitosis -- but the
infrastructure appears to be holding up nicely.

expression parser. It is now possible to type:
(lldb) expr int $i = 5; $i + 1
(int) 6
(lldb) expr $i + 2
(int) 7
The skeleton for automatic result variables is
also implemented. The changes affect:
- the process, which now contains a
ClangPersistentVariables object that holds
persistent variables associated with it
- the expression parser, which now uses
the persistent variables during variable
lookup
- TaggedASTType, where I loaded some commonly
used tags into a header so that they are
interchangeable between different clients of
the class
llvm-svn: 110777
including superclass members. This involved ensuring
that access control was ignored, and ensuring that
the operands of BitCasts were properly scanned for
variables that needed importing.
Also laid the groundwork for declaring objects of
custom types; however, this functionality is disabled
for now because of a potential loop in ASTImporter.
