This adjusts header file includes for headers and source files
in Core. In doing so, one dependency cycle is eliminated
because all the includes from Core to that project were dead
includes anyway. In places where some files in other projects
were only compiling due to a transitive include from another
header, fixups have been made so that those files also include
the header they need. Tested on Windows and Linux, and plan
to address failures on OSX and FreeBSD after watching the
bots.

This moves the following classes from Core -> Utility.
ConstString
Error
RegularExpression
Stream
StreamString
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.

This was a bit tricky, especially for things like
OptionValueArray and OptionValueDictionary since they do some
funky string parsing. Rather than try to re-write line-by-line
I tried to make the StringRef usage idiomatic, even though
it meant often re-writing from scratch large blocks of code
in a different way while keeping true to the original intent.
The finished code is a big improvement though, and often much
shorter than the original code. All tests and unit tests
pass on Windows and Linux.

This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.
Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

This change introduces optional marking of the column within a source
line where a thread is stopped. This marking will show up when the
source code for a thread stop is displayed, when the debug info
knows the column information, and if the optional column marking is
enabled.
There are two separate methods for handling the marking of the stop
column:
* via ANSI terminal codes, which are added inline to the source line
display. The default ANSI mark-up is to underline the column.
* via a pure text-based caret that is added in the appropriate column
in a newly-inserted blank line underneath the source line in
question.
There are some new options that control how this all works.
* settings set stop-show-column
This takes one of 4 values:
* ansi-or-caret: use the ANSI terminal code mechanism if LLDB
is running with color enabled; if not, use the caret-based,
pure text method (see the "caret" mode below).
* ansi: only use the ANSI terminal code mechanism to highlight
the stop line. If LLDB is running with color disabled, no
stop column marking will occur.
* caret: only use the pure text caret method, which introduces
a newly-inserted line underneath the current line, where
the only character in the new line is a caret that highlights
the stop column in question.
* none: no stop column marking will be attempted.
* settings set stop-show-column-ansi-prefix
This is a text format that indicates the ANSI formatting
code to insert into the stream immediately preceding the
column where the stop column character will be marked up.
It defaults to ${ansi.underline}; however, it can contain
any valid LLDB format codes, e.g.
${ansi.fg.red}${ansi.bold}${ansi.underline}
* settings set stop-show-column-ansi-suffix
This is the text format that specifies the ANSI terminal
codes to end the markup that was started with the prefix
described above. It defaults to: ${ansi.normal}. This
should be sufficient for the common cases.
Significant leg-work was done by Adrian Prantl. (Thanks, Adrian!)

This updates getters and setters to use StringRef instead of
const char *. I tested the build on Linux, Windows, and OSX
and saw no build or test failures. I cannot test any BSD

mode in lldb works. I've been discussing this with Jim Ingham,
Greg Clayton, and Kate Stone for the past week or two.
Previously lldb would print three source lines (centered on the
line table entry line for the current line) followed by the assembly.
It would print the context information (module`function + offset)
before those three lines of source.
Now lldb will print up to two lines before/after the line table
entry. It prints two '*' characters for the line table line to
make it clear what line is showing assembly. There is one line of
whitespace before/after the source lines so the separation between
source & assembly is clearer. I don't print the context line
(module`function + offset). I stop printing context lines if it's
a different line table entry, or if it's a source line I've already
printed as context to another source line. If I have two line table
entries one after another for the same source line (I get these often
with clang - with different column information in them), I only print
the source line once.
I'm also using the target.process.thread.step-avoid-regexp setting
(which keeps you from stepping into STL functions that have been inlined
into your own code) and avoid printing any source lines from functions
that match that regexp.
When lldb disassembles into a new function, it will try to find the
declaration line # for the function and print all of the source lines
between the decl and the first line table entry (usually a { curly brace)
so we have a good chance of including the arguments, at least with the
debug info emitted by clang.
Finally, the # of source lines of context to show has been separated
from whether we're doing mixed source & assembly or not. Previously
specifying 0 lines of context would turn off mixed source & assembly.
I think there's room for improvement, and maybe some bugs I haven't
found yet, but it's in good enough shape to upstream and iterate at
this point.
I'm not sure how best to indicate which source line is the actual line
table # versus context lines. I'm using '**' right now. Both Kate
and Greg had the initial idea to reuse '->' (normally used to indicate
"currently executing source line") - I tried it but I wasn't thrilled,
I'm too used to the established meaning of ->.
Greg had the interesting idea of avoiding context source lines only
in two line table entries in the same source file. So we'd print
two lines before & after a source line, and then the next line table
entry (if it was on the next source line after those two context lines)
we'd display only the following two lines -- the previous two had just
been printed. If an inline source line was printed between these two,
though, we'd print the context lines for both of them. It's an
interesting idea, and I want to see how it works with both -O0 and -O3
codegen where we have different amounts of inlining.

*** 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.

It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.
This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.
There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.
This patch depends on LLVM revision r278170.

in thumb mode into one method in ArchSpec, replace checks for
specific cores in the disassembler with calls to this. Also call
this from the arm instruction emulation code.
The determination of whether a given ArchSpec is thumb-only is still
a bit of a hack, but at least the hack is consolidated into a single
place. In my original version of this patch http://reviews.llvm.org/D13578
I was calling into llvm's feature arm feature tables to make this
determination, like
#include "llvm/Support/TargetRegistry.h"
#include "llvm/MC/MCSubtargetInfo.h"
#include "llvm/../../lib/Target/ARM/ARMGenRegisterInfo.inc"
#include "llvm/../../lib/Target/ARM/ARMFeatures.h"
[...]
std::string triple (GetTriple().getTriple());
const char *cpu = "";
const char *features_str = "";
const llvm::Target *curr_target = llvm::TargetRegistry::lookupTarget(triple.c_str(), Error);
std::unique_ptr<llvm::MCSubtargetInfo> subtarget_info_up (curr_target->createMCSubtargetInfo(triple.c_str(), cpu, features_str));
if (subtarget_info_up->getFeatureBits()[llvm::ARM::FeatureNoARM])
{
return true;
}
but those tables are post-llvm-build generated and linking against them
for all of our different build system methods was a big hiccup that I
haven't had time to revisit convincingly.
I'll keep that reviews.llvm.org patch around to remind myself that I
need to take another run at linking against the necessary tables
again in llvm.

SUMMARY:
This patch implements Target::GetBreakableLoadAddress() method that takes an address
and checks for any reason there is a better address than this to put a breakpoint on.
If there is then return that address.
MIPS uses this method to avoid breakpoint in delay slot.

Create a new "lldb_private::CompilerDeclContext" class that will replace all direct uses of "clang::DeclContext" when used in compiler agnostic code, yet still allow for conversion to clang::DeclContext subclasses by clang specific code. This completes the abstraction of type parsing by removing all "clang::" references from the SymbolFileDWARF. The new "lldb_private::CompilerDeclContext" class abstracts decl contexts found in compiler type systems so they can be used in internal API calls. The TypeSystem is required to support CompilerDeclContexts with new pure virtual functions that start with "DeclContext" in the member function names. Converted all code that used lldb_private::ClangNamespaceDecl over to use the new CompilerDeclContext class and removed the ClangNamespaceDecl.cpp and ClangNamespaceDecl.h files.
Removed direct use of clang APIs from SBType and now use the abstract type systems to correctly explore types.
Bulk renames for things that used to return a ClangASTType which is now CompilerType:
"Type::GetClangFullType()" to "Type::GetFullCompilerType()"
"Type::GetClangLayoutType()" to "Type::GetLayoutCompilerType()"
"Type::GetClangForwardType()" to "Type::GetForwardCompilerType()"
"Value::GetClangType()" to "Value::GetCompilerType()"
"Value::SetClangType (const CompilerType &)" to "Value::SetCompilerType (const CompilerType &)"
"ValueObject::GetClangType ()" to "ValueObject::GetCompilerType()"
many more renames that are similar.

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.

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
on it anyway, so it was just a dead include in every single instance.
