860bafa07d Fix raw address breakpoints not resolving
Summary: An address breakpoint of the form "b 0x1000" won't resolve if it's created while the process isn't running. This patch deletes Address::SectionWasDeleted, renames Address::SectionWasDeletedPrivate to SectionWasDeleted (and makes it public), and changes the section check in Breakpoint::ModulesChanged back to its original form

431b158400 Support setting a breakpoint by FileSpec+Line+Column in the SBAPI.
This patch extends the SBAPI to allow for setting a breakpoint not
only at a specific line, but also at a specific (minimum) column. When
a column is specified, it will try to find an exact match or the
closest match on the same line that comes after the specified
location.

7aa4ed9b5f If a function starts with line number 0, don't try to check if a breakpoint crossed function boundaries.
clang doesn't use line number 0 (to mean artifically generated code) very often, but swift does it
quite often.  We were rejecting all by line breakpoints in functions that started at line 0.  But that's
a special marker so we can just not do this test in that case.

0faca0f09f [lldbsuite, windows] Mark tests as XFAIL on Windows or skip them
Summary:
1) Several tests that are flakey on windows fail the run even if they are marked as expected to be flakey. This is because they fail frequently enough that even a retry won't help
2) Skip several tests on Windows that will occasionally hang rather than failing or exiting. This is causing the entire test suite to hang

aa6c3f50e3 [lldbsuite] Fix TestBreakpointHitCount on Windows
Summary: On Windows, the newer DIA SDKs end up producing function names that contain the return type as well. This means that the function name returned in the test will contain the return type (int) in addition to the name of the function and the type of the input (a(int)). To account for the possibility of both, the test should pass if the function name matches either pattern.

0583d7a56c Make test sources compatible with android+libcxx+modules
In a modules build, android is very picky about which symbols are
visible after including libc++ headers (e.g. <cstdio> defines only
std::printf and not ::printf).

This consolidates the tests where this was an issue to always include
the <c???> version of the headers and prefixes the symbols with std:: as
necessary.

Apart from that, there is no functional change in the tests.

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.

63047d05c0 [dotest] Clean up test folder clean-up
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.

7c94582f90 Add "lldb-test breakpoint" command and convert the case-sensitivity test to use it
Summary:
The command takes two input arguments: a module to use as a debug target
and a file containing a list of commands. The command will execute each
of the breakpoint commands in the file and dump the breakpoint state
after each one.

The commands are expected to be breakpoint set/remove/etc. commands, but
I explicitly allow any lldb command here, so you can do things like
change setting which impact breakpoint resolution, etc. There is also a
"-persistent" flag, which causes lldb-test to *not* automatically clear
the breakpoint list after each command. Right now I don't use it, but
the idea behind it was that it could be used to test more complex
combinations of breakpoint commands (set+modify, set+disable, etc.).

Right now the command prints out only the basic breakpoint state, but
more information can be easily added there.  To enable easy matching of
the "at least one breakpoint location found" state, the command
explicitly prints out the string "At least one breakpoint location.".

To enable testing of breakpoints set with an absolute paths, I add the
ability to perform rudimentary substitutions on the commands: right now
the string %p is replaced by the directory which contains the command
file (so, under normal circumstances, this will perform the same
substitution as lit would do for %p).

I use this command to rewrite the TestBreakpointCaseSensitivity test --
the test was checking about a dozen breakpoint commands, but it was
launching a new process for each one, so it took about 90 seconds to
run. The new test takes about 0.3 seconds for me, which is approximately
a 300x speedup.

This test was failing on Windows because it expected the breakpoint in the

isn't loaded until the process is launched this didn't work.

The fix creates a special value (-2) for num_expected_locations that ignores
the actual number of breakpoint locations found.

a9f8b0d1a9 Avoid dirtying the source tree in breakpoint command tests
Summary:
The paralelization patch exposed a bunch of cases where we were still
touching the source tree (as these tests were now stepping on each
others toes and being flaky).

This patch removes such issues from breakpoint command tests. Since the
only reason they were creating files was to indirectly test whether the
breakpoint commands got executed (and plumbing the full build tree path
to all places that needed it would be messy) I decided to modify the
tests to check for a different side effect instead: modification of a
global variable. This also makes the code simpler as checking the value
of the global variable is easier, and there is nothing to clean up.

As the tests aren't really doing anything debug-info related, I took the
opportunity to also mark them as NO_DEBUG_INFO_TESTCASEs.

5ec76fe720 Compile the LLDB tests out-of-tree.
This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.

For each test (should be eventually: each test configuration) a
separate build directory is created and we execute

  make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test

In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.

Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.

b842f2ecf0 Make breakpoint names real entities.
When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.  

This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint.  It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names.  There is also full support for
then in the SB API, including a new SBBreakpointName class.

The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well.  This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.

You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.

I also added the ability to make hidden and delete/disable protected
names.  When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.

This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally 
disabled or deleted.

f08f5c9926 Add an auto-continue flag to breakpoints & locations.
You can get a breakpoint to auto-continue by adding "continue"
as a command, but that has the disadvantage that if you hit two
breakpoints simultaneously, the continue will force the process
to continue, and maybe even forstalling the commands on the other.
The auto-continue flag means the breakpoints can negotiate about
whether to stop.

breakpoints, so I also added that ability.

When an option was set at on a location, I was just copying the whole option set

it meant changes to unrelated options on the breakpoint would no longer take on this

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).
