IRInterpreter to get the value, not the location,
of references. The location of a reference has
type T&&, which is meaningless to Clang.
llvm-svn: 143592
allows us to set __attribute__ ((used)) on expressions
that masquerade as methods. When we are stopped in
classes in anonymous namespaces, this fix (and enabling
__attribute__ ((used)) on the method) will allow
expressions to run.
llvm-svn: 143560
Fixed an issue where the DWARF might mention that a class has a constructor
(default, copy or move), destructor, or an assignment operator (copy or move)
and it might not have an actual implementation in your code. Then you try and
use this struct or class in an expression and the JIT would ask for the
address of these methods that were in the declaration, yet there are none.
We now "do the right thing" for trivial ctors, dtors and assignment operators
by telling the methods that they are are defaulted and trivial, and clang will
then just do all of the work with builtins!
llvm-svn: 143528
generated special member functions (constructors,
destructors, etc.) for classes that don't really have
them. We needed to mark these as artificial to reflect
the debug information; this bug does that for
constructors and destructors.
The "etc." case (certain assignment operators, mostly)
remains to be fixed.
llvm-svn: 143526
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.
llvm-svn: 143520
method as __attribute__ ((used)) when adding it to a
class. This functionality is useful when stopped in
anonymous namespaces: expressions attached to classes
in anonymous namespaces are typically elided by Clang's
CodeGen because they have no namespaces are intended
not to be externally visible. __attribute__ ((used))
forces CodeGen to emit the function.
Right now, __attribute__ ((used)) causes the JIT not to
emit the function, so we're not enabling it until we
fix that.
llvm-svn: 143469
RegisterContextLLDBs it contains.
Previously RegisterContextLLDB objects had a pointer to their "next"
frame down the stack. e.g. stack starts at frame 0; frame 3 has a
pointer to frame 2. This is used to retreive callee saved register
values. When debugging an inferior that has blown out its own stack,
however, this could result in lldb blowing out its own stack while
recursing down to retrieve register values.
RegisterContextLLDB no longer has a pointer to its next frame; it
has a reference to the UnwindLLDB which contains it. When it needs
to retrieve a reg value, it asks the UnwindLLDB for that reg value
and UnwindLLDB iterates through the frames until it finds a location.
llvm-svn: 143423
"object borked"... Also made the error when the checker fails reflect this fact rather than
report a crash at 0x0.
Also a little cleanup:
- StopInfoMachException had a redundant copy of the description string.
- ThreadPlanCallFunction had a redundant copy of the thread, and had a
copy of the process that it didn't really need.

ClangExpressionDeclMap to ClangASTSource, and

AST importer on completing namespace mappings from
ClangExpressionDeclMap to ClangASTSource.
ClangASTSource now contains a TargetSP which it

look up globals.
llvm-svn: 143275
command suffix:
(lldb) expression/x 3+3
Since "expression" is a raw command that has options, we need to make sure the
command gets its options properly terminated with a "--".
Also fixed an issue where if you try to use the GDB command suffix on a
command that doesn't support the "--gdb-format" command, it will report an
appropriate error.
For the fix above, you can query an lldb_private::Options object to see if it
supports a long option by name.
llvm-svn: 143266
allow it to complete types on behalf of any AST context
(including the "scratch" AST context associated with
the target), I scrapped its role as intermediary between
the Clang parser and ClangExpressionDeclMap, and instead
made ClangExpressionDeclMap inherit from ClangASTSource.
After this, I will migrate the functions that complete
types and perform namespace lookups from
ClangExpressionDeclMap to ClangASTSource. Ultimately
ClangExpressionDeclMap's only responsiblity will be to
look up variables and ensure that they are materialized
and dematerialized correctly.
llvm-svn: 143253
things like:
(lldb) x/32xb 0x1000
"x" is an alias to "memory read", so this will actually turn into:
(lldb) memory read --gdb-format=32xb 0x1000
This applies to all commands, so the GDB formats will work with "register read",
"frame variable", "target variable" and others. All commands that can accept
formats, counts and sizes have been modified to support the "--gdb-format"
option.
llvm-svn: 143230
then we spawn child processes (debugserver, etc) and those bad settings get
inherited. We stop this from happening by correctly mucking with the posix
spawn attributes.
llvm-svn: 143176
Fixed an issue where async packets were incurring a delay even though they
were sent correctly. We now properly broadcast the private run state being
resumed correctly. Also fixed logging to reflect what is happening.
llvm-svn: 143154
of reference types. Previously, such variables were
materialized as references to those references, which
caused undesried behavior in Clang and was useless anyway
(the benefit of using references to variables is that it
allows expressions to modify variables in place, but for
references that's not required).
Now we just materialize the references directly, which
fixes a variety of expressions that use references.
llvm-svn: 143137
in the same hashed format as the ".apple_names", but they map objective C
class names to all of the methods and class functions. We need to do this
because in the DWARF the methods for Objective C are never contained in the
class definition, they are scattered about at the translation unit level and
they don't even have attributes that say the are contained within the class
itself.
Added 3 new formats which can be used to display data:
eFormatAddressInfo
eFormatHexFloat
eFormatInstruction
eFormatAddressInfo describes an address such as function+offset and file+line,
or symbol + offset, or constant data (c string, 2, 4, 8, or 16 byte constants).
The format character for this is "A", the long format is "address".
eFormatHexFloat will print out the hex float format that compilers tend to use.
The format character for this is "X", the long format is "hex float".
eFormatInstruction will print out disassembly with bytes and it will use the
current target's architecture. The format character for this is "i" (which
used to be being used for the integer format, but the integer format also has
"d", so we gave the "i" format to disassembly), the long format is
"instruction".
Mate the lldb::FormatterChoiceCriterion enumeration private as it should have
been from the start. It is very specialized and doesn't belong in the public
API.

"_cmd", "this", and "self". These variables are handled
differently from all other external variables used by
the expression. Other variables are used indirectly
through the $__lldb_arg operand; only _cmd, this, and
self are passed directly through the ABI.
There are two modifications:
- I added a function to ClangExpressionDeclMap that
retrives the value of one of these variables by name;
and
- I made IRInterpreter fetch these values when needed,
and ensured that the proper level of indirection is
used.

properly marked as valid.
Also modified the "memory read" command to be able to intelligently repeat
subsequent memory requests, so now you can do:
(lldb) memory read --format hex --count 32 0x1000
Then hit enter to keep viewing the memory that follows the last valid request.
llvm-svn: 143015
linked against a debug LLVM, runs a variety of

ClangASTContext now calls this verifier whenever
it adds a Decl to a DeclContext, and the verifier
checks that the AccessSpecifier is sane.

OptionGroupFormat. Updated OptionGroupFormat to be able to also use the
"--size" and "--count" options. Commands that use a OptionGroupFormat instance
can choose which of the options they want by initializing OptionGroupFormat
accordingly. Clients can either get only the "--format", "--format" + "--size",
or "--format" + "--size" + "--count". This is in preparation for upcoming
chnages where there are alternate ways (GDB format specification) to set a
format.

Types so that DWARF with debug map can work flawlessly. With DWARF in .o files
the type ID was the DIE offset in the DWARF for the .o file which is not
unique across all .o files, so now the SymbolFileDWARFDebugMap class will
make the .o file index part (the high 32 bits) of the unique type identifier
so it can uniquely identify the types.

Right now, the portion that runs the LLDB test

You can use the buildbot like this:
./scripts/buildbot.py -b /tmp/lldb-build -l /tmp/lldb.log
/tmp/lldb-build and /tmp/lldb.log should not exist
when the script is run.
/tmp/lldb-build is a temporary directory and is

/tmp/lldb.log is a log file that sticks around.

context object. Having it populated and registered
within a single FindExternalVisibleDecls call worked
fine when there was only one call (i.e., when we were
just looking in the global namespace).
However, now FindExternalVisibleDecls is called for
nested namespaces as well, which means that it is
called not once but many times (once per module in
which the parent namespace appears). This means that
the namespace mapping is built up across many calls
to the inferior FindExternalVisibleDecls, so I moved
it into a data structure (the search context) that is
shared by all calls.
I also added some logging to make it easier to see
what is happening during a namespace search, and
cleaned up some existing logging.
