relocations (LLVM revision 153147). Now when
we report section locations in the target process,
LLVM will apply both those relocations whose
targets are in that section and those relocations
which reside in that section and point to other
sections.

the migration to ModuleSpec objects this broke and is now fixed.
Also fixed a case in the darwin kernel dynamic loader where we just need to
trust the load address of the kernel if we can't read it from memory.

Each platform now knows if it can handle an architecture and a platform can be found using an architecture. Each platform can look at the arch, vendor and OS and know if it should be used or not.

LLDB can match incorrect line table entries when an address is between two valid line entries (in the gap between the valid debug info), now it doesn't!
llvm-svn: 153077
(lldb) file /path/to/file.so
(lldb) crashlog crash.log
....
Then if the file.so has already been loaded it will use the one that is already in LLDB without trying to match up the paths.

to pass to the toolchain in order to build the inferior programs to be run/debugged
duirng the test suite. The architecture might dictate some special CFLAGS which are
more easily specified in a central place (like the command line) instead of inside
make rules.
For Example,
./dotest.py -v -r /shared/phone -A armv7 -E "-isysroot your_sdk_root" functionalities/watchpoint/hello_watchpoint
will relocate the particular test directory ('functionalities/watchpoint/hello_watchpoint' in this case) to a
new directory named '/shared/phone'. The particular incarnation of the architecture-compiler combination of the
test support files are therefore to be found under:
/shared/phone.arch=armv7-compiler=clang/functionalities/watchpoint/hello_watchpoint
The building of the inferior programs under testing is now working.
The actual launching/debugging of the inferior programs are not yet working,
neither is the setting of a watchpoint on the phone.
llvm-svn: 153070
Changes to synthetic children:
- the update(self): function can now (optionally) return a value - if it returns boolean value True, ValueObjectSyntheticFilter will not clear its caches across stop-points
this should allow better performance for Python-based synthetic children when one can be sure that the child ValueObjects have not changed
- making a difference between a synthetic VO and a VO with a synthetic value: now a ValueObjectSyntheticFilter will not return itself as its own synthetic value, but will (correctly)
claim to itself be synthetic
- cleared up the internal synthetic children architecture to make a more consistent use of pointers and references instead of shared pointers when possible
- major cleanup of unnecessary #include, data and functions in ValueObjectSyntheticFilter itself
- removed the SyntheticValueType enum and replaced it with a plain boolean (to which it was equivalent in the first place)
Some clean ups to the summary generation code
Centralized the code that clears out user-visible strings and data in ValueObject
More efficient summaries for libc++ containers
llvm-svn: 153061
Fixed a case where the source path remappings on the module were too expensive to
use when we try to verify (stat the file system) that the remapped path points to
a valid file. Now we will use the lldb_private::Module path remappings (if any) when
parsing the debug info without verifying that the paths exist so we don't slow down
line table parsing speeds.

- Clang now completes all Objective-C objects (if
they are not already complete, and they have
external lexical sources) during structure
layout, avoiding a LLDB crash.
- The Clang Decl printer handles reference types
correctly. This prevents LLDB from crashing
when expression logging is enabled.

For the time being, skip the relevant disassemble action which resulted in a crash.
Minor modification (print out format) to the existing TestDisassembleRawBytes.py test file.

Fixed a case where if you have a argument stirng that ends with a '\' character, it would infinite loop while consuming all of your memory.
Also fixed a case where non-quote terminated strings would inefficiently be handled.

Made sure that the root XPC service validate the right before starting the service. The right is created and authenticated by clients (in this case, lldb) and transferred over for validiation.
llvm-svn: 152802
Now when LLDB reports a variable, it has a
complete type. Similarly, when it reports
members of a struct, it completes their types.
Also, when it creates the result variable for
an expression, it ensures that variable's type
is complete.
This ensures compliance with Clang's
expectations, preventing potential crashes.
llvm-svn: 152771

Fixed a case where a missing "break" in a switch statement could cause an assertion to fire and kill the debug session.
The fix was derived from the findings of Andrea Bigagli, thanks Andrea.
llvm-svn: 152741
Fixed an issue with the FUNC_STARTS load command where we would get the
symbol size wrong and we would add all sorts of symbols due to bit zero being
set to indicate thumb.
llvm-svn: 152696
Simplify the locking strategy for Module and its owned objects to always use the Module's mutex to avoid A/B deadlocks. We had a case where a symbol vendor was locking itself and then calling a function that would try to get it's Module's mutex and at the same time another thread had the Module mutex that was trying to get the SymbolVendor mutex. Now any classes that inherit from ModuleChild should use the module lock using code like:
void
ModuleChildSubclass::Function
{
ModuleSP module_sp(GetModule());
if (module_sp)
{
lldb_private::Mutex::Locker locker(module_sp->GetMutex());
... do work here...
}
}
This will help avoid deadlocks by using as few locks as possible for a module and all its child objects and also enforce detecting if a module has gone away (the ModuleSP will be returned empty if the weak_ptr does refer to a valid object anymore).
llvm-svn: 152679
For EmulateInstructionARM::EmulatePUSH(), fix the logical branch for when pc is pushed to behave
like the other cases where:
context.SetRegisterToRegisterPlusOffset (reg_info, sp_reg, addr - sp);
is called to inform of the operation to set a register value to a memory location calculated from
a base register plus an offset.
llvm-svn: 152670
This has been done for those summaries where the difference is only cosmetic (e.g. naming things as items instead of values, ...)
The LLDB output style has been preserved when it provides more information (e.g. telling the type as well as the value of an NSNumber)
Test cases have been updated to reflect the updated output style where necessary
llvm-svn: 152592
std::string has a summary provider
std::vector std::list and std::map have both a summary and a synthetic children provider
Given the usage of a custom namespace (std::__1::classname) for the implementation of libc++, we keep both libstdcpp and libc++ formatters enabled at the same time since that raises no conflicts and enabled for seamless transition between the two
The formatters for libc++ reside in a libcxx category, and are loaded from libcxx.py (to be found in examples/synthetic)
The formatters-stl test cases have been divided to be separate for libcxx and libstdcpp. This separation is necessary because
(a) we need different compiler flags for libc++ than for libstdcpp
(b) libc++ inlines a lot more than libstdcpp and some code changes were required to accommodate this difference
llvm-svn: 152570
load notification for the first load) then we will set it the runtime to NULL and won't re-search for it.
Added a way for the dynamic loader to force a re-search, since it knows the world has changed.
llvm-svn: 152453
Get function boundaries from the LC_FUNCTION_STARTS load command. This helps to determine symbol sizes and also allows us to be able to debug stripped binaries.
If you have a stack backtrace that goes through a function that has been stripped from the symbol table, the variables for any functions above that stack frame will most likely be incorrect. It can also affect our ability to step in/out/through of a function.
llvm-svn: 152381
Don't show variable values in Xcode when they are out of scope. This allows Xcode to step a lot faster when there are many variables in the variables view.
llvm-svn: 152380
This solves an issue where a ValueObject was getting a wrong children count (usually, a huge value) and trying to resize the vector of children to fit that many ValueObject*
Added a loop detection algorithm to the synthetic children provider for std::list
Added a few more checks to the synthetic children provider for std::vector
Both std::list and std::vector's synthetic children providers now cache the count of children instead of recomputing it every time
std::map has a field that stores the count, so there is little need to cache it on our side

This takes two important changes:
- Calling blocks is now supported. You need to
cast their return values, but that works fine.
- We now can correctly run JIT-compiled
expressions that use floating-point numbers.
Also, we have taken a fix that allows us to
ignore access control in Objective-C as in C++.
llvm-svn: 152286
Added a new makefile target to help us with Apple builds where the installhdrs
will copy the headers for the shared library. Prior to this fix, the install
headers directory would contain the unix style paths to all public header
files ("#include lldb/API/SBDefines.h") instead of the fixed up framework
header paths ("#include <LLDB/SBDefines.h>").
llvm-svn: 152253
This fix really needed to happen as a previous fix I had submitted for
calculating symbol sizes made many symbols appear to have zero size since
the function that was calculating the symbol size was calling another function
that would cause the calculation to happen again. This resulted in some symbols
having zero size when they shouldn't. This could then cause infinite stack
traces and many other side affects.

(a) the SystemParameters object is now passed around to the formatters; doing so enables the formatters to reuse computed values for things such as pointer-size and endianness
instead of repeatedly computing these on their own
(b) replacing the global ISA cache with a per-process one
(c) providing a per-process types cache where each formatter can store the types it needs to operate, and be sure to find them the next time without recalculating them
this also enables formatters to share types if they agree on a local naming convention
(d) lazy fetching of data from Objective-C runtime data structures
data is fetched as needed and we stop reading as soon as we determine that an ISA is actually garbage
