Jonas Devlieghere 937348cd13 [FileSpec] Make style argument mandatory for SetFile. NFC
SetFile has an optional style argument which defaulted to the native
style. This patch makes that argument mandatory so clients of the
FileSpec class are forced to think about the correct syntax.

At the same time this introduces a (protected) convenience method to
update the file from within the FileSpec class that keeps the current
style.

These two changes together prevent a potential pitfall where the style
might be forgotten, leading to the path being updated and the style
unintentionally being changed to the host style.

Adrian Prantl 05097246f3 Reflow paragraphs in comments.
This is intended as a clean up after the big clang-format commit
(r280751), which unfortunately resulted in many of the comment
paragraphs in LLDB being very hard to read.

FYI, the script I used was:

import textwrap
import commands
import os
import sys
import re
tmp = "%s.tmp"%sys.argv[1]
out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:
  header = ""
  text = ""
  comment = re.compile(r'^( *//) ([^ ].*)$')
  special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$')
  for line in f:
      match = comment.match(line)
      if match and not special.match(match.group(2)):
          # skip intentionally short comments.
          if not text and len(match.group(2)) < 40:
              out.write(line)
              continue

          if text:
              text += " " + match.group(2)
          else:
              header = match.group(1)
              text = match.group(2)

          continue

      if text:
          filled = textwrap.wrap(text, width=(78-len(header)),
                                 break_long_words=False)
          for l in filled:
              out.write(header+" "+l+'\n')
              text = ""

Greg Clayton 776cd7ad44 Always normalize FileSpec paths.
Always normalizing lldb_private::FileSpec paths will help us get a consistent results from comparisons when setting breakpoints and when looking for source files. This also removes a lot of complexity from the comparison routines. Modified the DWARF line table parser to use the normalized compile unit directory if needed.

Pavel Labath 145d95c964 Move Args.cpp from Interpreter to Utility
Summary:
The Args class is used in plenty of places besides the command
interpreter (e.g., anything requiring an argc+argv combo, such as when
launching a process), so it needs to be in a lower layer. Now that the
class has no external dependencies, it can be moved down to the Utility
module.

This removes the last (direct) dependency from the Host module to
Interpreter, so I remove the Interpreter module from Host's dependency
list.

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.

Mandeep Singh Grang 4ccea6230b [lldb] Unbreak lldb builds due to r327219
Summary:
r327219 adds wrappers to sort which shuffle the container before sorting.
This causes lldb bots to break as the call to sort is now ambiguous:
http://lab.llvm.org:8011/builders/lldb-x86_64-ubuntu-14.04-buildserver/builds/20725/steps/ninja%20build%20local/logs/stdio

So we need use llvm::sort instead of sort to avoid ambiguity with std::sort.

Note: This patch is just to unbreak the bots. I plan to have subsequent patches which will convert all
calls to std::sort to llvm::sort.

Jim Ingham 5ec7cd7227 Fix Breakpoint::RemoveInvalidLocations to fix the exec testcase.
RemoveInvalidLocations was clearing out the m_locations in the
breakpoint by hand, and it wasn't also clearing the locations from
the address->location map, which confused us when we went to update
breakpoint locations.  

I also made Breakpoint::ModulesChanged check the Location's Section
to make sure it hadn't been deleted.  This shouldn't strictly be necessary,
but if the DynamicLoaderPlugin doesn't do it's job right (I'm looking at
you new Darwin DynamicLoader...) then it can end up leaving stale locations
on rerun.  It doesn't hurt to clean them up here as a backstop.

Pavel Labath 5f19b90783 Move ArchSpec to the Utility module
The rationale here is that ArchSpec is used throughout the codebase,
including in places which should not depend on the rest of the code in
the Core module.

This commit touches many files, but most of it is just renaming of
 #include lines. In a couple of cases, I removed the #include ArchSpec
line altogether, as the file was not using it. In one or two places,
this necessitated adding other #includes like lldb-private-defines.h.

Jim Ingham 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.

Jim Ingham 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.

Writing tests, I wanted to supply some commands when I made the
breakpoints, so I also added that ability.

Jim Ingham af26b22cd2 Fix a mis-feature with propagation of breakpoint options -> location options.
When an option was set at on a location, I was just copying the whole option set 
to the location, and letting it shadow the breakpoint options.  That was wrong since
it meant changes to unrelated options on the breakpoint would no longer take on this
location.  I added a mask of set options and use that for option propagation.

I also added a "location" property to breakpoints, and added SBBreakpointLocation.{G,S}etCommandLineCommands
since I wanted to use them to write some more test cases.

This renames the LLDB error class to Status, as discussed

A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error".  Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around.  Hopefully nothing too
serious.

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).

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

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.

Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.

In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.

For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.

There seems to be something fundamentally wrong with this patch: it uses

of the step-over-watchpoint logic (which AFAIK is the only user of this class) is
to disable the watchpoint *after* we resume to do the single step.
