Ed Maste 111387c47b Simplify POSIXThread register context handling
This seems a little more straightforward and is equivalent to r201457
for ELF core files.  A case for FreeBSD i386 is also added (it was
incorrectly using the 64-bit register context and corrupting mememory).

Better (user-facing) error handling is still needed.

Todd Fiala 620ea83926 Fixed configure-based build on OS X.
This change adds a missing include path to the
ObjC LanguageRuntime path to the MacOSX SystemRuntime
plugin's Makefile.

It also adds the panel and curses library to the liblldb
shared library linkage step.

* test_signal_watch_break_dwarf (line 260 - same named test?)
* test_crash_with_watchpoint_dwarf
* test_crash_with_watchpoint_breakpoint_signal_dwarf
* test_delayed_crash_with_breakpoint_watchpoint_dwarf

Marks as expected failure (these all fail consistently):

Todd Fiala 4507f06aaa Fix linux x86 debugging on a linux x86 host (32-bit on 32-bit).
This change fixes up issues with specifying the size of the i386
register infos for FPU registers.  The bug was that for the i386
register context, the size of the FPU registers were still being
computed based on the x86_64 FXSAVE structure.

This change permits the FPR_SIZE macro to optionally be defined
outside of RegisterInfos_i386.h, which RegisterContextLinux_i386.cpp
does properly. It redefines the FPR_i386 structure with all the
accessible parts that RegisterInfos_i386.h wants to see, which we had
not done before when we made the overall size of the structure
properly sized a recently.

This change also modifies POSIXThread to create a
RegisterContextLinux_i386 only when the host is 32-bit; otherwise, it
uses the RegisterContextLinux_x86_64, which works properly for 32-bit
and 64-bit inferiors on a 64-bit host.

I tested this debugging a Linux x86 exe on an x86 host (Ubuntu 13.10
x86), and debugging a Linux x86 exe and a Linux x86-64 exe on an
x86-64 host (Ubuntu 12.04 LTS).  Those cases all worked.

Thanks to Matthew Gardiner who discoverd may key insights into
tracking down the issue. The motivation for this change and some of
the code originates from him via this thread:

Todd Fiala 9bb71b73d9 Suppress python readline module under Linux to fix a seg fault.
Bug fix for pr18841:
http://llvm.org/bugs/show_bug.cgi?id=18841

This change creates a stub Python readline.so module that does almost
nothing. Its whole purpose is to prevent Python from loading the real
module, something it does during the embedded Python interpreter's
initialization sequence (and way before lldb ever requests it within
embedded_interpreter.py).

On Ubuntu 12.04 and 13.10 x86_64, and in the Python 2.7.6 tree, the
stock Python readline module links against the GNU readline library.
This appears to be the case on all Pythons except where __APPLE__ is
defined. LLDB now requires linking against the libedit library.
Something about having both libedit.so and libreadline.so linked into
the same process space is causing the Python readline.so to trigger a
NULL memory access. I have put in a separate patch to python.org.

This suppression of embedded interpreter readline support can be
removed if at least any one of the following happens:

1. The stock python distribution accepts a patch similar to what I
submitted to Python 2.7.6's Modules/readline.c file.

2. The stock python distribution implements Modules/readline.c in
terms of libedit's readline compatibility mode (i.e. essentially
compiles it the way __APPLE__ compiles that module) under Linux.

3. a clean-room implementation of the python readline module is
implemented against libedit (either readline compatibility mode or
native libedit). This could be implemented within the readline.cpp
file that this change introduces. It cannot be a fork of python's
readline.c module due to llvm licensing.

The net effect of this change on Linux is that the embedded python's
readline support will not exist.

Jason Molenda 31d7ad4ecf Add a new idea of a "fallback" UnwindPlan to the RegisterContextLLDB
class.  If we try to unwind a stack frame to find a caller stack
frame, and we fail to get a valid-looking frame, AND if the UnwindPlan
we used is an assembly-inspection based UnwindPlan, then we should 
throw away the assembly-inspection UnwindPlan and try unwinding with 
the architectural default UnwindPlan.  

This code path won't be taken if eh_frame unwind instructions are available -
lldb will always prefer those once it's off the zeroth frame.

The problem I'm trying to fix here is the class of unwind failures that
happen when we have hand-written assembly on the stack, with no eh_frame,
and lldb's assembly parser fails to understand the assembly.  People usually
write their hand-written assembly to follow the frame-pointer-preserving
conventions of the platform so the architectural default UnwindPlan will 
often work.  We won't have the spill location for most of the non-volatile
registers if we fall back to this, but it's better than stopping the unwind
prematurely.

This is a bit of a tricky change that I believe is correct, but if we get
unwinds that go of into the weeds / unwind bogus frames at the end of the
stack, I'll need to revisit it.

Jason Molenda 6223db2778 The Platform base class now maintains a list of trap handlers
aka asynchronous signal handlers, which subclasses should fill
in as appropriate.  For most Unix user process environments,
the one entry in this list is _sigtramp.  For bare-board and
kernel environments, there will be different sets of trap 
handlers.

The unwinder needs to know when a frame is a trap handler 
because the rules it enforces for the frame "above" the
trap handler is different from most middle-of-the-stack frames.

Jason Molenda 9098f1d3d9 Change the ABI CallFrameAddressIsValid methods for i386 and x86_64.
They were enforcing 16-byte alignment on stack frames for Darwin x86 programs.
But we've found that trap handlers typically don't have the stack pointer
aligned correctly when a trap happens and lldb wasn't backtracing all
the way through.  This method is only used as a safety guard to prevent
lldb's unwinder from using a bogus address as a stack frame - we'll still
enforce word-size alignment on stack frames so that should be fine.

Also rolled back akaylor's changes from August 2013 in r188952 which changed
the i386 ABI plugin to relax the CallFrameAddressIsValid offsets for non-Darwin
targets where only 4-byte alignment is enforced.  Now Darwin is the same as
those environments.

Elf core files were collapsing core segments when the virtual memory

memory region was the same size as the segment's VMA region. Without
this extra check, any time regions were collapsed but the core-backed
region was smaller (and thus had a zero-filled hole at the end), the
collapse operation would break VMA to core file lookups for subsequent
collapsed regions.

Saleem Abdulrasool 78c135942d Host: unconstify editline paramters
Although the interface to el_push should be a constant parameter (as it is on
Darwin), certain Linux distributions currently ship a header which does not
provide proper const correctness.  This causes compilation failures on Linux.
Strip the constness on the parameter, which whilst incorrect, is mostly
harmless.  The parameter will not be changed by the interface and so it is
acceptable to do this.  When distributions have updated to a more correct
declaration, it would be nice to revert this change.

                            bool value_is_offset);

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.

Greg Clayton 9b5442aed9 Now that the command interpreter runs in a separate thread in Xcode, we need to lock the target API lock instead of trying to lock it.
What was happening was:
1 - Xcode ran and stopped and was doing work on thread 2
2 - Users would type something in Xcode console on thread 1
3 - thread 3 would be running command interpreter thread and try to execute command but get "failed to get API lock" error for any command that wanted the target API lock (like "expression")

When a user says

type formatter add ... unsigned int

he most probably means to deal with the "unsigned int" type. However, given how the LLDB command parser works, that command will try to add the formatter to the TWO types 'unsigned' AND 'int'

Since this is unlikely to be what the user wants, warn about it, and suggest they can use quotes to override the debugger's understanding

Steve Pucci 9e02dacddf Factor some methods that were in DynamicLoaderPOSIXDYLD.
Move some code that was in DynamicLoaderPOSIXDLYD into the
base class DynamicLoader.  In the case of UpdateLoadedSections(),
the test to see whether a file is loadable (its address is zero)
is not generally applicable so that test is changed to a more
universally applicable check for the SHF_ALLOC flag on the section.

Also make it explicit that the reading of the module_id in
DynamicLoaderPOSIXDYLD::GetThreadLocalData() is using a hardcoded
size (of module_id) of 4, which might not be appropriate on
big-endian 64-bit systems, leaving a FIXME comment in place.
