Pavel Labath 225b79524d Remove HostThreadLinux/Free/NetBSD
Summary:
These classes existed only because of the GetName() static function,
which can be moved to a more natural place anyway. I move the linux
version to NativeProcessLinux (and get rid of ProcFileReader), the
freebsd version to ProcessFreeBSD (and fix a bug where it was using the
current process ID, instead of the inferior pid), and remove the NetBSD
version (which was probably incorrect anyway, as it assumes the current
process instead of the inferior.

I also add an llgs test to that verifies thread names are read
correctly.

Pavel Labath bf37a037d0 BreakpointResolverFileLine: Restrict move-to-nearest-code from moving across function boundaries
Summary:
This fixes the case where a user tries to set a breakpoint on a source
line outside of any function (e.g. because that code is #ifdefed out, or
the compiler did not emit code for the function, etc.) and we would
silently move the breakpoint to the next function.

Now we check whether the line range of the resolved symbol context
function matches the original line number. We reject any breakpoint
locations that appear to move the breakpoint into a new function. This
filtering only happens if we have full debug info available (e.g. in
case of -gline-tables-only compilation, we still set the breakpoint on
the nearest source line).

Pavel Labath 2f1fbaebe2 gdb-remote: Add jModulesInfo packet
Summary:
This adds the jModulesInfo packet, which is the equivalent of qModulesInfo, but it enables us to
query multiple modules at once. This makes a significant speed improvement in case the
application has many (over a hundred) modules, and the communication link has a non-negligible
latency. This functionality is accessed by ProcessGdbRemote::PrefetchModuleSpecs(), which does
the caching. GetModuleSpecs() is modified to first consult the cache before asking the remote
stub. PrefetchModuleSpecs is currently only called from POSIX-DYLD dynamic loader plugin, after
it reads the list of modules from the inferior memory, but other uses are possible.

This decreases the attach time to an android application by about 40%.

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.

Todd Fiala e77fce0a50 [NFC] Darwin llgs support from Week of Code
This code represents the Week of Code work I did on bringing up
lldb-server LLGS support for Darwin.  It does not include the
Xcode project changes needed, as we don't want to throw that switch
until more support is implemented (i.e. this change is inert, no
build systems use it yet.  I've verified on Ubuntu 16.04, macOS
Xcode and macOS cmake builds).

This change does some minimal refactoring of code that is shared
with the Linux LLGS portion, moving it from NativeProcessLinux into
NativeProcessProtocol.  That code is also used by NativeProcessDarwin.

Current state on Darwin:
* Process launching is implemented.  (Attach is not).
  Launching on devices has not yet been tested (FBS/BKS might
  need a bit of work).
* Inferior waitpid monitoring and communication of exit status
  via MainLoop callback is implemented.
* Memory read/write, breakpoints, thread register context, etc.
  are not yet implemented.  This impacts process stop/resume, as
  the initial launch suspended immediately starts the process
  up and running because it doesn't know it is supposed to remain
  stopped.
* I implemented the equivalent of MachThreadList as
  NativeThreadListDarwin, in anticipation that we might want to
  factor out common parts into NativeThreadList{Protocol} and share
  some code here.  After writing it, though, the fallout from merging
  Mach Task/Process into a single concept plus some other minor
  changes makes the whole NativeThreadListDarwin concept nothing more
  than dead weight.  I am likely going to get rid of this class and
  just manage it directly in NativeProcessDarwin, much like I did
  for NativeProcessLinux.
* There is a stub-out call for starting a STDIO thread.  That will
  go away and adopt the MainLoop pselect-based IOObject reading.

I am developing the fully-integrated changes in the following repo,
which contains the necessary Xcode bits and the glue that enables
lldb-debugserver on a macOS system:

  https://github.com/tfiala/lldb/tree/llgs-darwin

This change also breaks out a few of the lldb-server tests into
their own directory, and adds some $qHostInfo tests (not sure why
I didn't write those tests back when I initially implemented that
on the Linux side).

These two test cases:
  tools/lldb-server/lldbgdbserverutils.py
  python_api/process/TestProcessAPI.py
actually check for big-endian target byte order, but contain Python errors
in the corresponding code paths.

These test cases:

  python_api/sbdata/TestSBData.py  (first change)
could be fixed to check for big-endian target byte order and update the
expected result strings accordingly.  For the two synthetic tests, I've
also updated the source to make sure the fake_a value is always nonzero
on both big- and little-endian platforms.

These test case:

Ulrich Weigand bb00d0b6b2 Support Linux on SystemZ as platform
This patch adds support for Linux on SystemZ:
- A new ArchSpec value of eCore_s390x_generic
- A new directory Plugins/ABI/SysV-s390x providing an ABI implementation
- Register context support
- Native Linux support including watchpoint support
- ELF core file support
- Misc. support throughout the code base (e.g. breakpoint opcodes)
- Test case updates to support the platform

This should provide complete support for debugging the SystemZ platform.
Not yet supported are optional features like transaction support (zEC12)
or SIMD vector support (z13).

There is no instruction emulation, since our ABI requires that all code
provide correct DWARF CFI at all PC locations in .eh_frame to support
unwinding (i.e. -fasynchronous-unwind-tables is on by default).

The implementation follows existing platforms in a mostly straightforward
manner.  A couple of things that are different:

- We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers,
  since some registers (access register) reside at offsets in the user area
  that are multiples of 4, but the PTRACE_PEEKUSER interface only allows
  accessing aligned 8-byte blocks in the user area.  Instead, we use a s390
  specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that
  allows accessing a whole block of the user area in one go, so in effect
  allowing to treat parts of the user area as register sets.

- SystemZ hardware does not provide any means to implement read watchpoints,
  only write watchpoints.  In fact, we can only support a *single* write
  watchpoint (but this can span a range of arbitrary size).  In LLDB this
  means we support only a single watchpoint.  I've set all test cases that
  require read watchpoints (or multiple watchpoints) to expected failure
  on the platform.  [ Note that there were two test cases that install
  a read/write watchpoint even though they nowhere rely on the "read"
  property.  I've changed those to simply use plain write watchpoints. ]
