Pavel Labath 0e33a0cd58 DebugNamesDWARFIndex: Implement DWARFDeclContext variant of GetTypes method
This method is used to find complete definitions of a type when one
parses a compile unit with only forward declaration available.

Since it is only accessed from DWARFASTParserClang, it was not
possible/easy to trigger this codepath from lldb-test. Therefore, I
adapt add a debug-names variant to an existing dotest test to cover this
scenario.

Jonas Devlieghere 9deaf68ed1 Exempt some compilers from new static variable test.
Apparently some compilers generate incomplete debug information which

Leonard Mosescu e1bb51789d Add a new SBTarget::LoadCore() overload which surfaces errors if the load fails
There was no way to find out what's wrong if SBProcess SBTarget::LoadCore(const char *core_file) failed. 
Additionally, the implementation was unconditionally setting sb_process, so it wasn't even possible to check if the return SBProcess is valid.

This change adds a new overload which surfaces the errors and also returns a valid SBProcess only if the core load succeeds:

SBProcess SBTarget::LoadCore(const char *core_file, SBError &error);

Pavel Labath 663773857f dotest: make inline tests compatible with -f
Summary:
This is split off from D47265 where I needed to be able to invoke every test
with -f. That patch is kinda dead now, but this part seems like a good
cleanup anyway.

The problem with inline tests was in the way we were adding methods to
the class, which left them with an incorrect __name__ property. This
prevented dotest from finding them with -f.

I fix this with (what I think is) the correct way of dynamically
creating classes -- passing the list of methods during type construction
instead of fixing up the class afterwards. Among other things this has
the advantage of not needing to do anything special for debug info
variants. As our test method will be visible to the metaclass, it will
automagically do the multiplication for us.

James Y Knight 9c2d52014c Fix support for distinguishing archive members by timestamp on Darwin.
On Darwin, the binary's symbol table points to debug info in object
files -- potentially object files within a static library. Such a
library may have multiple entries with the same name, distinguished
only by timestamp.

The code was already _attempting_ to handle this case (see the code in
ObjectContainerBSDArchive::Archive::FindObject which disambiguates via
timestamp). But, unfortunately, while the timestamp was taken into
account on the _first_ lookup, the result was then cached in a map
keyed only off of the path.

Added the timestamp to the cache, and added a test case.

Frederic Riss 9cd4def1c6 Fix Module::FindTypes to return the correct number of matches.
In r331719, I changed Module::FindTypes not to limit the amount
of types returned by the Symbol provider, because we want all
possible matches to be able to filter them. In one code path,
the filtering was applied to the TypeList without changing the
number of types that gets returned. This is turn could cause
consumers to access beyond the end of the TypeList.

This patch fixes this case and also adds an assertion to
TypeList::GetTypeAtIndex to catch those obvious programming
mistakes.

Triggering the condition in which we performed the incorrect
access was not easy. It happened a lot in mixed Swift/ObjectiveC
code, but I was able to trigger it in pure Objective C++ although
in a contrieved way.

Frederic Riss 1739b7d076 Really test type lookup in TestCppTypeLookup.py
Summary:
... and fix one bug found this way. Currently, the test works not because
types are looked up correctly, but because by injecting local variables
we also materialize the types for Clang. If we disable the local variable
injection, then one check fails.

The reason of the failure is that FindTypes is run with max_matches==1
and this value is passed down to the symbol lookup functions. When the
search is performed only on the basename (like it's the case for an
entity defined in the root namespace), then the search will stop after
having found one match on the basename. But that match might be in a
namespace, we were really just looking up the basename in the accelerator
tables.

The solution is to not pass max_matches down, but to search without a
limit and let RemoveMismatchedTypes do its job afterwards. Note the
patch includes 2 hunks with the same change, but only the latter is
tested. I couldn't find a way to create a testcase for the other
branch of the if ('image lookup -t' allows me to get there, but it
only ever returns one type anyway).

Jason Molenda b81afd6598 Fix the .experimental. settings feature so that we don't return an error
if an experimental setting has been removed/is missing.

Add tests for the .experimental. settings behaviors -- that they correctly
forward through to the real setting if it has become a real setting,
that they don't generate errors when a settig has been removed.

As Pavel notes in https://reviews.llvm.org/D45348, the way I'm suppressing
errors in the setting is not completely correct - if any of the setting
path components include "experimental", a missing setting would be declared
a non-error.  So

settings set target.experimental.setting-that-does-not-exist true

would not generate an error, which is correct.  But as Pavel notes, 

settings set setting-does-not-exist.experimental.run-stopped true

should generate an error because the unknown name occurs before the
"experimental".  The amount of change to do this correctly hasn't
thrilled me, so I'm leaving this as-is for now.

Adrian Prantl ce05952943 Remove premature caching of the global variables list in CompileUnit.
This fixes a bug where

  (lldb) target var g_ptr

would populate the global variables list with exactly one entry
because SymbolFileDWARF::ParseVariables() was invoked with a list of
DIEs pre-filtered by name, such that a subsequent call to

  (lldb) fr var --show-globals

would only list that one variable, because CompileUnit::m_variables
was already initialized, fooling CompileUnit::GetVariableList().

CompileUnit::GetVariableList() grabs the *complete* list of variables
via (SymbolFileDWARF, ...)::ParseVariablesForContext and that still
calls CompileUnit::SetVariableList(variables) which acts as the
caching mechanism.

The new script to run the lldbtests as part of lit invokes each test by calling dotest.py, however, we cannot rely on the system to always correctly interpret the script as python causing the tests to be unresolved on windows (at least). To fix this, we need to make sure that the first parameter in the command line is the python executable itself.

In Makefile.rules, there are a number of windows specific definitions that rely on the HOST_OS being set as Windows_NT but the logic detecting the OS currently does not detect server versions of windows correctly. This change updates the logic to detect windows server as well.

This patch makes the set of generated test variants static and handles
the skipping via runtime checks instead. This is more consistent with
how we do other test-skipping decision (e.g. for libc++ tests), and
makes it easier to expose the full set of tests to lit, which now does
not need to know anything about what things can potentially cause tests
to appear or disappear.

Pavel Labath 5976f30821 Attempt to fix TestMiniDump on windows
It was failing because the modules names were coming out as
C:\Windows\System32/MSVCP120D.dll (last separator is a forward slash) on
windows.

There are two issues at play here:
- the first problem is that the paths in minidump were being parsed as a
  host path. This meant that on posix systems the whole path was
  interpreted as a file name.
- on windows the path was split into a directory-filename pair
  correctly, but then when it was reconsituted, the last separator ended
  up being a forward slash because SBFileSpec.fullpath was joining them
  with '/' unconditionally.

I fix the first issue by parsing the minidump paths according to the
path syntax of the host which produced the dump, which should make the
test behavior on posix&windows identical. The last path will still be a
forward slash because of the second issue. We should probably fix the
"fullpath" property to do something smarter in the future.

Leonard Mosescu 47196a25bb Improve LLDB's handling of non-local minidumps
Normally, LLDB is creating a high-fidelity representation of a live
process, including a list of modules and sections, with the 
associated memory address ranges. In order to build the module and
section map LLDB tries to locate the local module image (object file)
and will parse it.

This does not work for postmortem debugging scenarios where the crash
dump (minidump in this case) was captured on a different machine.

Fortunately the minidump format encodes enough information about
each module's memory range to allow us to create placeholder modules.
This enables most LLDB functionality involving address-to-module
translations.

Also, we may want to completly disable the search for matching
local object files if we load minidumps unless we can prove that the
local image matches the one from the crash origin.
(not part of this change, see: llvm.org/pr35193)

Example: Identify the module from a stack frame PC:

Before:
  thread #1, stop reason = Exception 0xc0000005 encountered at address 0x164d14
    frame #0: 0x00164d14
    frame #1: 0x00167c79
    frame #2: 0x00167e6d
    frame #3: 0x7510336a
    frame #4: 0x77759882
    frame #5: 0x77759855

After:
  thread #1, stop reason = Exception 0xc0000005 encountered at address 0x164d14
    frame #0: 0x00164d14 C:\Users\amccarth\Documents\Visual Studio 2013\Projects\fizzbuzz\Debug\fizzbuzz.exe
    frame #1: 0x00167c79 C:\Users\amccarth\Documents\Visual Studio 2013\Projects\fizzbuzz\Debug\fizzbuzz.exe
    frame #2: 0x00167e6d C:\Users\amccarth\Documents\Visual Studio 2013\Projects\fizzbuzz\Debug\fizzbuzz.exe
    frame #3: 0x7510336a C:\Windows\SysWOW64\kernel32.dll
    frame #4: 0x77759882 C:\Windows\SysWOW64\ntdll.dll
    frame #5: 0x77759855 C:\Windows\SysWOW64\ntdll.dll

Example: target modules list

Before:
error: the target has no associated executable images

After:
[ 0] C:\Windows\System32\MSVCP120D.dll 
[ 1] C:\Windows\SysWOW64\kernel32.dll 
[ 2] C:\Users\amccarth\Documents\Visual Studio 2013\Projects\fizzbuzz\Debug\fizzbuzz.exe 
[ 3] C:\Windows\System32\MSVCR120D.dll 
[ 4] C:\Windows\SysWOW64\KERNELBASE.dll 
[ 5] C:\Windows\SysWOW64\ntdll.dll

NOTE: the minidump format also includes the debug info GUID, so we can
fill-in the module UUID from it, but this part was excluded from this change
to keep the changes simple (the LLDB UUID is hardcoded to be either 16 or
20 bytes, while the CodeView GUIDs are normally 24 bytes)

     2      int a = 6;
  -> 3      return 0;
     4    }
  (lldb) statistics enable
  (lldb) frame var a
  (int) a = 6
  (lldb) expr a
  (int) $1 = 6
  (lldb) statistics disable
  (lldb) statistics dump
  Number of expr evaluation successes : 1
  Number of expr evaluation failures : 0
  Number of frame var successes : 1
  Number of frame var failures : 0

Future improvements might include:

1. Passing a file, or implementing categories. The way this patch has
been implemented is generic enough to allow this to be extended
easily without breaking the grammar.
2. Adding an SBAPI and Python API for use in scripts.

Greg Clayton 52098cf5da Allow relative file paths when settings source breakpoints
Many IDEs set breakpoints using absolute paths and this causes problems when the full path of the source file path doesn't match what is in the debug info. This can be due to different build systems and do or do not resolve symlinks. This patch allows relative breakpoint to be set correctly without needing to do any target.source-map tricks. If IDEs want to, they can send down relative paths like:

./main.c
./src/main.c
src/main.c
foo/bar/src/main.c

I used the breakpoint resolver to match on the file basename and then we weed out anything whose relative paths don't match. This will be a huge improvement for IDEs as they can specify as much of a relative path as desired to uniquely identify a source file in the current project.

Frederic Riss cd90f878d4 [debugserver] Fix LC_BUILD_VERSION load command handling.
Summary:
In one of the 2 places the LC_BUILD_VERSION load command is handled, there
is a bug preventing us from actually handling them (the address where to
read the load command was not updated). This patch factors reading the
deployment target load commands into a helper and adds testing for the 2
code paths calling the helper.

The testing is a little bit complicated because the only times those load
commands matter is when debugging a simulator process. I added a new
decorator to check that a specific SDK is available. The actual testing was
fairly easy once I knew how to run a simulated process.

When importing C++ methods into clang AST nodes from the DWARF symbol

Concretely, this enables `expression` to call into names that use the
GNU `abi_tag` extension, and enables lldb to call into code using
std::string or std::list from recent versions of libstdc++. See
https://bugs.llvm.org/show_bug.cgi?id=35310 . It also seems broadly
more robust than relying on the DWARF->clang->codegen pipeline to
roundtrip properly, but I'm not immediately aware of any other cases

Pavel Labath 9a652a84b1 Fix TestDisassembleBreakpoint broken by r328488
The first issue was that the test was capturing the "before" disassembly
before launching, and the "after" after. This is a problem because some
of the disassembly will change after we know the load address (e.g. PCs
in call instructions). I fix this by capturing both disassemblies with
the process running.

The second issue was that the refactor in r328488 accidentaly changed
the meaning of the test, as it was no longer disassembling the function
which contained the breakpoint.

Pavel Labath a057877a2e Add a test for setting the load address of a module with differing physical/virtual addresses
Summary:
First attempt at landing D42145 was reverted because it caused test
failures on some android devices. It turned out this was because these
devices had vdso modules with differing physical and virtual addresses.
This was not caught earlier because all of the modules in our tests
either lack physical addresses or have them identical to virtual ones.

In the discussion on the patch, we came to the conclusion that in the
scenario where we are merely setting a load address of a module (for
example from a dynamic loader plugin), we should always use virtual
addresses (i.e., preserve status quo). This patch adds a test to make
sure we don't regress in that direction.

The difference between this and the previous patch is that now we use
ELF physical addresses only for loading objects into the target (and the
rest of the module load address logic still uses virtual addresses).

Summary:
When writing an object file over gdb-remote, use the vFlashErase, vFlashWrite, and vFlashDone commands if the write address is in a flash memory region.  A bare metal target may have this kind of setup.

- Update ObjectFileELF to set load addresses using physical addresses.  A typical case may be a data section with a physical address in ROM and a virtual address in RAM, which should be loaded to the ROM address.
- Add support for querying the target's qXfer:memory-map, which contains information about flash memory regions, leveraging MemoryRegionInfo data structures with minor modifications
- Update ProcessGDBRemote to use vFlash commands in DoWriteMemory when the target address is in a flash region

Summary:
This patch implements a unified way of cleaning the build folder of each
test. This is done by completely removing the build folder before each
test, in the respective setUp() method. Previously, we were using a
combination of several methods, each with it's own drawbacks:
- nuking the entire build tree before running dotest: the issue here is
  that this did not take place if you ran dotest manually
- running "make clean" before the main "make" target: this relied on the
  clean command being correctly implemented. This was usually true, but
  not always.
- for files which were not produced by make, each python file was
  responsible for ensuring their deleting, using a variety of methods.

With this approach, the previous methods become redundant. I remove the
first two, since they are centralized. For the other various bits of
clean-up code in python files, I indend to delete it when I come
across it.

Pavel Labath 0428ddd7fc Fix TestProcessLaunch breakage on MacOS
This test started failing after r327625. The cause seems difference in the
treatment of relative --stdin paths between MacOS (debugserver?) and linux
(lldb-server?). Linux treats this as relative to the debuggers PWD, while MacOS
as relative to (I think) the future PWD of the launched process.

This fixes the issue by using absolute paths, which should work everywhere, but
we should probably unify this path handling as well. I'll ask around about what
is the expected behavior here.

Pavel Labath 107052ff9d Next batch of test-tree-cleaning changes
Summary:
The changes here fall into several categories.

- some tests were redirecting inferior stdout/err to a file. For these I
  make sure we use an absolute path for the file. I also create a
  lldbutil.read_file_on_target helper function to encapsulate the
  differences between reading a file locally and remotely.
- some tests were redirecting the pexpect I/O into a file. For these I
  use a python StringIO object to avoid creating a file altogether.
- the TestSettings inferior was creating a file. Here, I make sure the
  inferior is launched with pwd=build-dir so that the files end up
  created there.
- lldb-mi --log (used by some tests) creates a log file in PWD without
  the ability say differently. To make this work I make sure to run
  lldb-mi with PWD=build_dir. This in turn necessitated a couple of
  changes in other lldb-mi tests, which were using relative paths to
  access the source tree.

Greg Clayton 9cc222c80d Fix a bug in "target.source-map" where we would resolve unmapped paths incorrectly
When using:

(lldb) settings set target.source-map ./ /path/to/source
LLDB would fail to set a source file and line breakpoint with:

(lldb) breakpoint set --file /path/to/source/main.c --line 2
Because code in the target was undoing the remapping of "/path/to/source/main.c" to "./main.c" and then it would resolve this path, which would append the current working directory to the path. We don't want to resolve paths that we unmap.

Test case added.

Davide Italiano b84d653e9b [Dictionary] Rewrite the test added in r327587 as an inline test.
Until we have a better story for putting commands and check lines
in the same file (they're currently ignored), it seems that inline
tests are actually more concise and easier to understand.
Too bad we have still some python boilerplate, but that's not
really substantial so we can live with it.

Thanks to Fred for pointing out and Jim for explaining me how
to use the inline test format.
