Zachary Turner 97206d5727 Rename Error -> Status.
This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.

A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error".  Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around.  Hopefully nothing too
serious.

Jason Molenda 2b0a7be96e Change the kernel searching code to not go through the
memory cache subsystem so we're reading only the 4 bytes
needed to check for the magic word at the start of a mach-o
binary instead of the default 512 block.  It can be a small
performance help to reduce the size of memory reads from 
possibly unmapped memory.

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

Saleem Abdulrasool 16ff860469 remove use of Mutex in favour of std::{,recursive_}mutex
This is a pretty straightforward first pass over removing a number of uses of
Mutex in favor of std::mutex or std::recursive_mutex. The problem is that there
are interfaces which take Mutex::Locker & to lock internal locks. This patch
cleans up most of the easy cases. The only non-trivial change is in
CommandObjectTarget.cpp where a Mutex::Locker was split into two.

Greg Clayton c44bcec6e1 LLDB top of tree SVN fails to attach to a MacOSX native process by pid only (no executable).
The problem was that the static DynamicLoaderDarwinKernel::Initialize() was recently changed to come before DynamicLoaderMacOSXDYLD::Initialize() which caused the DynamicLoaderDarwinKernel::CreateInstance(...) to be called before DynamicLoaderMacOSXDYLD::CreateInstance(...) and DynamicLoaderDarwinKernel would claim it could be the dynamic loader for a user space MacOSX process. The fix is to make DynamicLoaderDarwinKernel::CreateInstance() a bit more thourough when vetting the process so that it doesn't claim MacOSX user space processes.

Jim Ingham 2411167fb5 Add an "offset" option to "break set -n" and "break set -f -l".
That way you can set offset breakpoints that will move as the function they are 
contained in moves (which address breakpoints can't do...)

I don't align the new address to instruction boundaries yet, so you have to get
this right yourself for now.

Jason Molenda 880988af09 ProcessMachCore scans through the core file pages looking for a
user process dyld binary and/or a mach kernel binary image.  By
default, it prefers the kernel if it finds both.

But if it finds two kernel binary images (which can happen when
random things are mapped into memory), it may pick the wrong
kernel image.  

DynamicLoaderDarwinKernel has heuristics to find a kernel in memory;
once we've established that there is a kernel binary in memory,
call over to that class to see if it can find a kernel address via
its search methods.  If it does, use that.

Some minor cleanups to DynamicLoaderDarwinKernel while I was at it.

Bruce Mitchener 9ccb970f23 Make lldb::endian::InlHostByteOrder() private.
Summary:
Since this is within the lldb namespace, the compiler tries to
export a symbol for it. Unfortunately, since it is inlined, the
symbol is hidden and this results in a mess of warnings when
building on OS X with cmake.

Moving it to the lldb_private namespace eliminates that problem.

Dawn Perchik 23b1decbe7 Add support for specifying a language to use when parsing breakpoints.
Target and breakpoints options were added:
    breakpoint set --language lang --name func
    settings set target.language pascal
These specify the Language to use when interpreting the breakpoint's
expression (note: currently only implemented for breakpoints on
identifiers).  If the breakpoint language is not set, the target.language
setting is used.
This support is required by Pascal, for example, to set breakpoint at 'ns.foo'
for function 'foo' in namespace 'ns'.
Tests on the language were also added to Module::PrepareForFunctionNameLookup
for efficiency.

Ewan Crawford 90ff791141 Expression evaluation, a new ThreadPlanCallFunctionUsingABI for executing a function call on target via register manipulation
For Hexagon we want to be able to call functions during debugging, however currently lldb only supports this when there is JIT support. 
Although emulation using IR interpretation is an alternative, it is currently limited in that it can't make function calls.

In this patch we have extended the IR interpreter so that it can execute a function call on the target using register manipulation. 
To do this we need to handle the Call IR instruction, passing arguments to a new thread plan and collecting any return values to pass back into the IR interpreter. 

The new thread plan is needed to call an alternative ABI interface of "ABI::PerpareTrivialCall()", allowing more detailed information about arguments and return values.

Zachary Turner 1124045ac7 Don't #include "lldb-python.h" from anywhere.
Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.

None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

Now "value" is a slide if "value_is_offset" is true, and "value" is an image base address otherwise. All previous usage of this API was using slides.

Updated the ObjectFileELF and ObjectFileMachO SetLoadAddress methods to do the right thing.

Also updated the ObjectFileMachO::SetLoadAddress() function to not load __LINKEDIT when it isn't needed and to only load sections that belong to the executable object file.

4 - it is now possible to use curses to drive LLDB (please try the "gui" command)

Fixed the test case for "test/functionalities/exec/TestExec.py" on Darwin.

The issue was breakpoints were persisting and causing problems. When we exec, we need to clear out the process and target and start fresh with nothing and let the breakpoints populate themselves again. This patch correctly clears out the breakpoints and also flushes the process so that the objects (process/thread/frame) give out valid information.

Jason Molenda b57e4a1bc6 Roll back the changes I made in r193907 which created a new Frame
pure virtual base class and made StackFrame a subclass of that.  As
I started to build on top of that arrangement today, I found that it
wasn't working out like I intended.  Instead I'll try sticking with
the single StackFrame class -- there's too much code duplication to
make a more complicated class hierarchy sensible I think.

Jason Molenda f23bf7432c Add a new base class, Frame. It is a pure virtual function which
defines a protocol that all subclasses will implement.  StackFrame
is currently the only subclass and the methods that Frame vends are
nearly identical to StackFrame's old methods.

Update all callers to use Frame*/Frame& instead of pointers to
StackFrames.

This is almost entirely a mechanical change that touches a lot of
the code base so I'm committing it alone.  No new functionality is
added with this patch, no new subclasses of Frame exist yet.

I'll probably need to tweak some of the separation, possibly moving
some of StackFrame's methods up in to Frame, but this is a good
starting point.

Added a way to set hardware breakpoints from the "breakpoint set" command with the new "--hardware" option. Hardware breakpoints are not a request, they currently are a requirement. So when breakpoints are specified as hardware breakpoints, they might fail to be set when they are able to be resolved and should be used sparingly. This is currently hooked up for GDB remote debugging. 

Linux and FreeBSD should quickly enable this feature if possible, or return an error for any breakpoints that are hardware breakpoint sites in the "virtual Error Process::EnableBreakpointSite (BreakpointSite *bp_site);" function.

Fixed ProcessMachCore to be able to locate the main executeable in the core file even if it doesn't start at a core file address range boundary. Prior to this we only checked the first bytes of each range in the core file for mach_kernel or dyld. Now we still do this, but if we don't find the mach_kernel or dyld anywhere, we go through all core file ranges and check every 0x1000 to see if we can find dyld or the mach_kernel.

Now that we can properly detect the mach_kernel at any address, we don't need to call "DynamicLoaderDarwinKernel::SearchForDarwinKernel(Process*)" anymore.
