Jaydeep Patil 501a781998 [LLDB][MIPS] Detect MIPS application specific extensions like micromips
SUMMARY:
    The patch detects MIPS application specific extensions (ASE) like micromips by reading 
    ELF header.e_flags and SHT_MIPS_ABIFLAGS section. MIPS triple does not contain ASE 
    information like micromips, mips16, DSP, MSA etc. These can be read from header.e_flags 
    or SHT_MIPS_ABIFLAGS section.

Siva Chandra f8877efc8b Add a class ValueObjectConstResultCast.
Summary:
Other changes around the main change include:

1. Add a method Cast to ValueObjectConstResult, ValueObjectConstResultImpl
and ValueObjectConstResultChild.

2. Add an argument |live_address| of type lldb::addr_t to the constructor
of ValueObjectConstResultChild. This is passed on to the backing
ValueObjectConstResultImpl object constructor so that the address of the
child value can be calculated properly.

Greg Clayton 358cf1ea30 Resubmitting 240466 after fixing the linux test suite failures.
A few extras were fixed

- Symbol::GetAddress() now returns an Address object, not a reference. There were places where people were accessing the address of a symbol when the symbol's value wasn't an address symbol. On MacOSX, undefined symbols have a value zero and some places where using the symbol's address and getting an absolute address of zero (since an Address object with no section and an m_offset whose value isn't LLDB_INVALID_ADDRESS is considered an absolute address). So fixing this required some changes to make sure people were getting what they expected. 
- Since some places want to access the address as a reference, I added a few new functions to symbol:
    Address &Symbol::GetAddressRef();
    const Address &Symbol::GetAddressRef() const;

Linux test suite passes just fine now.

Greg Clayton ffb2d44ab9 Reduced packet counts to the remote GDB server where possible.
We have been working on reducing the packet count that is sent between LLDB and the debugserver on MacOSX and iOS. Our approach to this was to reduce the packets required when debugging multiple threads. We currently make one qThreadStopInfoXXXX call (where XXXX is the thread ID in hex) per thread except the thread that stopped with a stop reply packet. In order to implement multiple thread infos in a single reply, we need to use structured data, which means JSON. The new jThreadsInfo packet will attempt to retrieve all thread infos in a single packet. The data is very similar to the stop reply packets, but packaged in JSON and uses JSON arrays where applicable. The JSON output looks like:


[
  { "tid":1580681,
    "metype":6,
    "medata":[2,0],
    "reason":"exception",
    "qaddr":140735118423168,

    ]
  }
]

It contains an array of dicitionaries with all of the key value pairs that are normally in the stop reply packet. Including the expedited registers. Notice that is also contains expedited memory in the "memory" key. Any values in this memory will get included in a new L1 cache in lldb_private::Process where if a memory read request is made and that memory request fits into one of the L1 memory cache blocks, it will use that memory data. If a memory request fails in the L1 cache, it will fall back to the L2 cache which is the same block sized caching we were using before these changes. This allows a process to expedite memory that you are likely to use and it reduces packet count. On MacOSX with debugserver, we expedite the frame pointer backchain for a thread (up to 256 entries) by reading 2 pointers worth of bytes at the frame pointer (for the previous FP and PC), and follow the backchain. Most backtraces on MacOSX and iOS now don't require us to read any memory!

We will try these packets out and if successful, we should port these to lldb-server in the near future.

Ed Maste f6a1312f1b Improve OSType initialization in elf object file's arch_spec
Setting the OSType in the ArchSpec triple is needed to correctly setup
up the register context plugin. ArchSpec::SetArchitecture, for Mach-O
only, sets the OSType. For ELF it was left to the ObjectFileELF to fill
in the missing OSType.

This change moves the ObjectFileELF logic into ArchSpec.

A new optional 'os' parameter has been added to SetArchitecture.
For ELF, this value is the from the ELF header.e_ident[EI_OSABI].
The default value is 0 or ELFOSABI_NONE.

The real work of determining the OSType was done by the ObjectFileELF
helper function GetOsFromOSABI. This logic has been moved
SetArchitecture.

GetOsFromOSABI has been commented as being deprectated.  It is left in
to support asserts.

For ELF the vendor value returned from SetArchitecture should be
UnknownVendor.  An unneeded resetting in ObjectFileELF has been removed
and replaced with an assert.

This fixes a problem reading a core file on FreeBSD/ARM because the spec
triple was arm-unknown-unknown.

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

Pavel Labath 4446487d71 Improve LLDB prompt handling
Summary:
There is an issue in lldb where the command prompt can appear at the wrong time. The partial fix
we have in for this is not working all the time and is introducing unnecessary delays. This
change does:
- Change Process:SyncIOHandler to use integer start id's for synchronization to avoid it being
  confused by quick start-stop cycles. I picked this up from a suggested patch by Greg to
  lldb-dev.
- coordinates printing of asynchronous text with the iohandlers. This is also based on a
  (different) Greg's patch, but I have added stronger synchronization to it to avoid races.

Together, these changes solve the prompt problem for me on linux (both with and without libedit).
I think they should behave similarly on Mac and FreeBSD and I think they will not make matters
worse for windows.

Test Plan: Prompt comes out alright. All tests still pass on linux.

Enrico Granata 4518586234 A previous patch made it so that ValueObjects could update themselves even in the face of an invalid execution context (which was required for the dynamic and synthetic values of const objects)
It turns out, child values also need similar provisions

This patch simplifies things a bit allowing ValueObject subclasses to just declare whether they can accept an invalid context at update time, and letting the update machinery in the EvaluationPoint to the rest
Also, this lets ValueObjectChild proclaim that its parent chooses whether such blank-slate updates are possible

Ilia K 055ad9beba Add --move-to-nearest-code / target.move-to-nearest-code options (attempt 2)
This patch initially was committed in r237460 but later it was reverted (r237479) due to 4 new failures:
* TestExitDuringStep.py
* TestNumThreads.py
* TestThreadExit.py
* TestThreadStates.py

This patch also fixes these tests.

Enrico Granata bb642e5456 Constant result ValueObjects are - well - constant
And they also do not have a thread/frame attached to them

That makes dynamic and synthetic values attached to them impossible to update - which, among other things, makes it impossible to properly display persistent variables of types that could have such dynamic/persistent values

Fix this by making it so that a ValueObject can control its constantness (hint: dynamic and synthetic values cannot be constant) and whether it wants to let itself be updated when an invalid thread is around

Ilia K d9f1a78aa0 Add --move-to-nearest-code / target.move-to-nearest-code options
Summary:
This option forces to only set a source line breakpoint when there is an exact-match

This patch includes the following commits:
# Add the -m/--exact-match option in "breakpoint set" command
## Add exact_match arg in BreakpointResolverFileLine ctor
## Add m_exact_match field in BreakpointResolverFileLine
## Add exact_match arg in BreakpointResolverFileRegex ctor
## Add m_exact_match field in BreakpointResolverFileRegex
## Add exact_match arg in Target::CreateSourceRegexBreakpoint
## Add exact_match arg in Target::CreateBreakpoint
## Add -m/--exact-match option in "breakpoint set" command
# Add target.exact-match option to skip BP if source line doesn't match
## Add target.exact-match global option
## Add Target::GetExactMatch
## Refactor Target::CreateSourceRegexBreakpoint to accept LazyBool exact_match (was bool)
## Refactor Target::CreateBreakpoint to accept LazyBool exact_match (was bool)
# Add target.exact-match test in SettingsCommandTestCase
# Add BreakpointOptionsTestCase tests to test --skip-prologue/--exact-match options
# Fix a few typos in lldbutil.check_breakpoint_result func
# Rename --exact-match/m_exact_match/exact_match/GetExactMatch to --move-to-nearest-code/m_move_to_nearest_code/move_to_nearest_code/GetMoveToNearestCode
# Add exact_match field in BreakpointResolverFileLine::GetDescription and BreakpointResolverFileRegex::GetDescription, for example:
was:
```
1: file = '/Users/IliaK/p/llvm/tools/lldb/test/functionalities/breakpoint/breakpoint_command/main.c', line = 12, locations = 1, resolved = 1, hit count = 2
  1.1: where = a.out`main + 20 at main.c:12, address = 0x0000000100000eb4, resolved, hit count = 2
```
now:
```
1: file = '/Users/IliaK/p/llvm/tools/lldb/test/functionalities/breakpoint/breakpoint_command/main.c', line = 12, exact_match = 0, locations = 1, resolved = 1, hit count = 2
  1.1: where = a.out`main + 20 at main.c:12, address = 0x0000000100000eb4, resolved, hit count = 2
```

Test Plan:
./dotest.py -v --executable $BUILDDIR/bin/lldb functionalities/breakpoint/
./dotest.py -v --executable $BUILDDIR/bin/lldb settings/
./dotest.py -v --executable $BUILDDIR/bin/lldb tools/lldb-mi/breakpoint/

Vince Harron d7e6a4f2f0 Fixed a ton of gcc compile warnings
Removed some unused variables, added some consts, changed some casts
to const_cast. I don't think any of these changes are very
controversial.
