Current LLDB (that is without DWZ support) crashes accessing Fedora debug info:
READ of size 8 at 0x60200000ffc8 thread T0
#0 in DWARFDebugInfoEntry::BuildAddressRangeTable(SymbolFileDWARF*, DWARFCompileUnit const*, DWARFDebugAranges*) const tools/lldb/source/Plugins/SymbolFile/DWARF/DWARFDebugInfoEntry.cpp:1336
Greg Clayton: We will need a warning to be emitted in
SymbolFileDWARF::CalculateAbilities() stating we won't parse the DWARF due to
"unsupported DW_FORM value of 0x1f20".
Patch has been mostly written by Greg Clayton.

Summary:
Clang recently started to emit base address entries into the
.debug_ranges section to reduce the number of relocations needed. Lets
make sure LLDB can read them.

This patch does the following:
* Gets the header copy step to re-run whenever header change
* Gets the header fix-up step to re-run whenever headers are copied
* Removes lldb-private*.h headers from the installed headers

When building for iOS we build two variants of debugserver. One which supports UI functionality like Springboard for launching applications, and one which does not.
This patch adds support for building debugserver with and without UI support libraries being available.
llvm-svn: 309026
On iOS frameworks don't have versions or resources, they are flatter bundles. This updates the LLDB framework build to accommodate the flatter bundles.
llvm-svn: 309025
This adds an explicit step for processing the headers and restructures how the framework bundles are constructed. This should make the frameworks more reliably constructed.

s_source_map in ClangExternalASTSourceCommon.cpp is unguarded
and therefore can break in multithreaded conditions. This can
cause crashes in particular if multiple targets are being set
up at once.
This patch wraps s_source_map in a function that ensures
exclusivity, and makes every user of it use that function
instead.

Now -shlib flag can be provided alongside with names of symbols files:
(lldb) target symbols add --shlib stripper-lib.so unstripper-lib.so
This is helpful when default matching mechanisms by name and UUID
can't find a module, and the user needs to explicitly specify
which module the given symbol file belongs to.

This reapplies https://reviews.llvm.org/D35740 with a tweak to find
the section by name rather than type. Section types don't distinguish
between regular sections and their DWO counterparts.
llvm-svn: 308905
The DWO handling code can get confused by clang modules which also use
skeleton CUs to point to the object file with the full debug
info. This patch detects whether an object is a "real" DWO or a clang
module and prevents LLDB from interpreting clang modules as DWO. This
fixes the regression in TestWithModuleDebugging.

This commit removes a very old deprecated API that was causing compile failures for LLDB on Darwin. Since the comment says we only needed to keep the old API around for a few Xcode builds, and the comment was written 6 years ago... I think this can safely go away.

Cast to `const uint8_t *` instead of `uint8_t *` to avoid the warning
from GCC.
EmulationStateARM.cpp:206:34: warning: cast from type 'const void*' to type 'uint8_t* {aka unsigned char*}' casts away qualifiers [-Wcast-qual]
Cast to `const uint32_t *` and the explicitly cast away the const-ness
of the value. This seems pretty sketchy as the `DataExtractor` holds a
const reference to the data. However, this is no worse than before.

SBBreakpointLocation exposed the ignore count, but didn't expose
the hit count. Both values were exposed by SBBreakpoint and
SBWatchpoint, so this makes things a bit more consistent.

CMake target "check-lldb" runs the lldb dotest.py suite, but doesn't
collect the results in a usable format. In adding the arguments
necessary to collect these results, I found some minor bugs in CMake
that prevented dotest overrides from being used. This patch fixes them.

This refactoring changes two significant things about how the debugserver build system works:
(1) debugserver will include all appropriate architecture support, so we can now build arm or ppc debugservers
(2) debugserver can be built by itself, so you don't have to configure all of LLDB in order to generate debugserver.
llvm-svn: 308377
Summary:
It defined a couple of types (condition_t) which we don't use anymore,
as we have c++11 goodies now. I remove these definitions.
Also it unnecessarily included a couple of headers which weren't
necessary for it's operation. I remove these, and place the includes in
the relevant files (usually .cpp, usually in Host code) which use them.
This allows us to reduce namespace pollution in most of the lldb files
which don't need the OS-specific definitions.

llvm-svn: 308304
Summary:
The usage of shared_from_this forces us to separate construction and
initialization phases, because shared_from_this() is not available in
the constructor (or destructor). The shared semantics are not necessary,
as we always have a clear owner of the native process class
(GDBRemoteCommunicationServerLLDB object). Even if we need shared
semantics in the future (which I think we should strongly avoid),
reverting this will not be necessary -- the owners can still easily
store the native process object in a shared pointer if they really want
to -- this just prevents the knowledge of that from leaking into the
class implementation.
After this a NativeThread object will hold a reference to the parent
process (instead of a weak_ptr) -- having a process instance always
available allows us to simplify some logic in this class (some of it was
already simplified because we were asserting that the process is
available, but this makes it obvious).

While adding IPv6 support to debugserver I broke handling wildcard addresses and fully qualified address filtering. This patch resolves that bug and adds a test for matching the address "*".
