Zachary Turner 6f9e690199 Move Log from Core -> Utility.
All references to Host and Core have been removed, so this
class can now safely be lowered into Utility.

Zachary Turner bf9a77305f Move classes from Core -> Utility.
This moves the following classes from Core -> Utility.

ConstString
Error
RegularExpression
Stream
StreamString

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes.  So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

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.

Jim Ingham 1fd2f08ea9 Return the right answer for ShouldStop for the RunToAddress plan. This isn't
strictly necessary because RunToAddress is always used as a subsidiary plan, so
it's ShouldStop seldom matters.  But get it right anyway.

Zachary Turner 3294de270e Move lldb-log.cpp to core/Logging.cpp
So that we don't have to update every single #include in the entire
codebase to #include this new header (which used to get included by
lldb-private-log.h, we automatically #include "Logging.h" from
within "Log.h".

Greg Clayton eb023e75dc <rdar://problem/13635174>
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.

Jim Ingham 221d51cf84 Figure out the reply to "PlanExplainsStop" once when we stop and then use the cached
value.  This fixes problems, for instance, with the StepRange plans, where they know that
they explained the stop because they were at their "run to here" breakpoint, then deleted
that breakpoint, so when they got asked again, doh!  I had done this for a couple of plans
in an ad hoc fashion, this just formalizes it.

Also add a "ResumeRequested" in Process so that the code in the completion handlers can
tell the ShouldStop logic they want to resume rather than just directly resuming.  That allows 
us to handle resuming in a more controlled fashion.

Also, SetPublicState can take a "restarted" flag, so that it doesn't drop the run lock when
the target was immediately restarted.

Greg Clayton 5160ce5c72 <rdar://problem/13521159>
LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

Jim Ingham 0161b49cba Reworked the way Process::RunThreadPlan and the ThreadPlanCallFunction interoperate to fix problems where
hitting auto-continue signals while running a thread plan would cause us to lose control of the debug 
session.

Jim Ingham 2995077d8a Add "target.process.stop-on-shared-library-events" setting, and make it work.
Add the ability to give breakpoints a "kind" string, and have the StopInfoBreakpoint
print that in the brief description if set.  Also print the kind - if set - in the breakpoint
listing.
Give kinds to a bunch of the internal breakpoints.
We were deleting the Mac OS X dynamic loader breakpoint as though the id we had stored away was
a breakpoint site ID, but in fact it was a breakpoint id, so we never actually deleted it.  Fixed that.

Greg Clayton 1ac04c3088 Thread hardening part 3. Now lldb_private::Thread objects have std::weak_ptr
objects for the backlink to the lldb_private::Process. The issues we were
running into before was someone was holding onto a shared pointer to a 
lldb_private::Thread for too long, and the lldb_private::Process parent object
would get destroyed and the lldb_private::Thread had a "Process &m_process"
member which would just treat whatever memory that used to be a Process as a
valid Process. This was mostly happening for lldb_private::StackFrame objects
that had a member like "Thread &m_thread". So this completes the internal
strong/weak changes.

Documented the ExecutionContext and ExecutionContextRef classes so that our
LLDB developers can understand when and where to use ExecutionContext and 
ExecutionContextRef objects.

Jim Ingham f58a048776 Using the wrong type for the break id's (user_id_t is an unsigned int, but internal breakpoints can be negative, and anyway it is a good idea to use break_id_t for breakpoints, no?)
llvm-svn: 144254
2011-11-10 01:12:26 +00:00
Greg Clayton 81c22f6104 Moved lldb::user_id_t values to be 64 bit. This was going to be needed for
process IDs, and thread IDs, but was mainly needed for for the UserID's for
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.

Greg Clayton f3ef3d2af9 Added new lldb_private::Process memory read/write functions to stop a bunch
of duplicated code from appearing all over LLDB:

lldb::addr_t
Process::ReadPointerFromMemory (lldb::addr_t vm_addr, Error &error);

bool
Process::WritePointerToMemory (lldb::addr_t vm_addr, lldb::addr_t ptr_value, Error &error);

size_t
Process::ReadScalarIntegerFromMemory (lldb::addr_t addr, uint32_t byte_size, bool is_signed, Scalar &scalar, Error &error);

size_t
Process::WriteScalarToMemory (lldb::addr_t vm_addr, const Scalar &scalar, uint32_t size, Error &error);

in lldb_private::Process the following functions were renamed:

From:
uint64_t
Process::ReadUnsignedInteger (lldb::addr_t load_addr, 
                              size_t byte_size,
                              Error &error);

To:
uint64_t
Process::ReadUnsignedIntegerFromMemory (lldb::addr_t load_addr, 
                                        size_t byte_size,
                                        uint64_t fail_value, 
                                        Error &error);

Cleaned up a lot of code that was manually doing what the above functions do
to use the functions listed above.

Added the ability to get a scalar value as a buffer that can be written down
to a process (byte swapping the Scalar value if needed):

uint32_t 
Scalar::GetAsMemoryData (void *dst,
                        uint32_t dst_len, 
                        lldb::ByteOrder dst_byte_order,
                        Error &error) const;

The "dst_len" can be smaller that the size of the scalar and the least 
significant bytes will be written. "dst_len" can also be larger and the
most significant bytes will be padded with zeroes. 

Centralized the code that adds or removes address bits for callable and opcode
addresses into lldb_private::Target:

lldb::addr_t
Target::GetCallableLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;

lldb::addr_t
Target::GetOpcodeLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;

All necessary lldb_private::Address functions now use the target versions so
changes should only need to happen in one place if anything needs updating.

Fixed up a lot of places that were calling :

addr_t
Address::GetLoadAddress(Target*);

to call the Address::GetCallableLoadAddress() or Address::GetOpcodeLoadAddress()
as needed. There were many places in the breakpoint code where things could
go wrong for ARM if these weren't used.

Jim Ingham f48169bb4f Moved the code in ClangUserExpression that set up & ran the thread plan with timeouts, and restarting with all threads into a utility function in Process. This required a bunch of renaming.
Added a ThreadPlanCallUserExpression that differs from ThreadPlanCallFunction in that it holds onto a shared pointer to its ClangUserExpression so that can't go away before the thread plan is done using it.

Fixed the stop message when you hit a breakpoint while running a user expression so it is more obvious what has happened.

Greg Clayton 2d4edfbc6a Modified all logging calls to hand out shared pointers to make sure we
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

Jim Ingham b01e742af7 Two changes in this checkin. Added a ThreadPlanKind so that I can do some reasoning based on the kind of thread plan
without having to use RTTI.
Removed the ThreadPlanContinue and replaced with a ShouldAutoContinue query that serves the same purpose.  Having to push
another plan to assert that if there's no other indication the target should continue when this plan is popped was flakey
and error prone.  This method is more stable, and fixed problems we were having with thread specific breakpoints.
