Zachary Turner 2f3df6137a iwyu fixes for lldbCore.
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.

Zachary Turner 01c3243fc1 Remove dependencies from Utility to Core and Target.
With this patch, the only dependency left is from Utility
to Host.  After this is broken, Utility will finally be
standalone.

Zachary Turner bf9a77305f Move classes from Core -> Utility.
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.

Stephan Bergmann 17c7f70362 Replace APFloatBase static fltSemantics data members with getter functions
At least the plugin used by the LibreOffice build
(<https://wiki.documentfoundation.org/Development/Clang_plugins>) indirectly
uses those members (through inline functions in LLVM/Clang include files in turn
using them), but they are not exported by utils/extract_symbols.py on Windows,
and accessing data across DLL/EXE boundaries on Windows is generally
problematic.

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.

Pavel Labath 21159ee681 Make Scalar::GetValue more consistent
Summary:
It seems the original intention of the function was printing signed values in decimal format, and
unsigned values in hex (without the leading "0x"). However, signed and unsigned long were
exchanged, which lead to amusing test failures in TestMemoryFind.py.

Instead of just switching the two, I think we should just print everything in decimal here, as
the current behaviour is very confusing (especially when one does not request printing of types).
Nothing seems to depend on this behaviour except and we already have a way for the user to
request the format he wants when printing values for most commands (which presumably does not go
through this function).

I also add a unit tests for the function in question.

Bryan Chan 01319e93ab Avoid an assertion failure when a bit field is extracted from a value of the same size.
Summary: One of the cases handled by ValueObjectChild::UpdateValue() uses the entire width of the parent's scalar value as the size of the child, and extracts the child by calling Scalar::ExtractBitfield(). This seems valid but APInt::trunc(), APInt::sext() and APInt::zext() assert that the bit field must not have the same size as the parent scalar. Replacing those calls with sextOrTrunc(), zextOrTrunc(), sextOrSelf() and zextOrSelf() fixes the assertion failures.

This reverts commit r267833 as it breaks the build. It looks like some work in progress got
committed together with the actual fix, but I'm not sure which one is which, so I'll revert the
whole patch and let author resumbit it after fixing the build error.

Sean Callanan 8bdcd52251 Fixed a bug where const this would cause parser errors about $__lldb_expr.
In templated const functions, trying to run an expression would produce the
error

error: out-of-line definition of '$__lldb_expr' does not match any declaration in 'foo'
member declaration does not match because it is const qualified
error: 1 error parsing expression

which is no good.  It turned out we don't actually need to worry about "const,"
we just need to be consistent about the declaration of the expression and the
FunctionDecl we inject into the class for "this."

Also added a test case.

Ulrich Weigand 9521ad2a49 Fix usage of APInt.getRawData for big-endian systems
Recommit modified version of r266311 including build bot regression fix.

This differs from the original r266311 by:

- Fixing Scalar::Promote to correctly zero- or sign-extend value depending
  on signedness of the *source* type, not the target type.

- Omitting a few stand-alone fixes that were already committed separately.

Ulrich Weigand ca07434234 Fix usage of APInt.getRawData for big-endian systems
The Scalar implementation and a few other places in LLDB directly
access the internal implementation of APInt values using the
getRawData method.  Unfortunately, pretty much all of these places
do not handle big-endian systems correctly.  While on little-endian
machines, the pointer returned by getRawData can simply be used as
a pointer to the integer value in its natural format, no matter
what size, this is not true on big-endian systems: getRawData
actually points to an array of type uint64_t, with the first element
of the array always containing the least-significant word of the
integer.  This means that if the bitsize of that integer is smaller
than 64, we need to add an offset to the pointer returned by
getRawData in order to access the value in its natural type, and
if the bitsize is *larger* than 64, we actually have to swap the
constituent words before we can access the value in its natural type.

This patch fixes every incorrect use of getRawData in the code base.
For the most part, this is done by simply removing uses of getRawData
in the first place, and using other APInt member functions to operate
on the integer data.

This can be done in many member functions of Scalar itself, as well
as in Symbol/Type.h and in IRInterpreter::Interpret.  For the latter,
I've had to add a Scalar::MakeUnsigned routine to parallel the existing
Scalar::MakeSigned, e.g. in order to implement an unsigned divide.

The Scalar::RawUInt, Scalar::RawULong, and Scalar::RawULongLong
were already unused and can be simply removed.  I've also removed
the Scalar::GetRawBits64 function and its few users.

The one remaining user of getRawData in Scalar.cpp is GetBytes.
I've implemented all the cases described above to correctly
implement access to the underlying integer data on big-endian
systems.  GetData now simply calls GetBytes instead of reimplementing
its contents.

Finally, two places in the clang interface code were also accessing
APInt.getRawData in order to actually construct a byte representation
of an integer.  I've changed those to make use of a Scalar instead,
to avoid having to re-implement the logic there.

The patch also adds a couple of unit tests verifying correct operation
of the GetBytes routine as well as the conversion routines.  Those tests
actually exposed more problems in the Scalar code: the SetValueFromData
routine didn't work correctly for 128- and 256-bit data types, and the
SChar routine should have an explicit "signed char" return type to work
correctly on platforms where char defaults to unsigned.

Ulrich Weigand b00ef10b70 Make Scalar::GetBytes and RegisterValue::GetBytes const
Scalar::GetBytes provides a non-const access to the underlying bytes
of the scalar value, supposedly allowing for modification of those
bytes.  However, even with the current implementation, this is not
really possible.  For floating-point scalars, the pointer returned
by GetBytes refers to a temporary copy; modifications to that copy
will be simply ignored.  For integer scalars, the pointer refers
to internal memory of the APInt implementation, which isn't
supposed to be directly modifyable; GetBytes simply casts aways
the const-ness of the pointer ...

With my upcoming patch to fix Scalar::GetBytes for big-endian
systems, this problem is going to get worse, since there we need
temporary copies even for some integer scalars.  Therefore, this
patch makes Scalar::GetBytes const, fixing all those problems.

As a follow-on change, RegisterValues::GetBytes must be made const
as well.  This in turn means that the way of initializing a
RegisterValue by doing a SetType followed by writing to GetBytes
no longer works.  Instead, I've changed SetValueFromData to do
the equivalent of SetType itself, and then re-implemented
SetFromMemoryData to work on top of SetValueFromData. 

There is still a need for RegisterValue::SetType, since some
platform-specific code uses it to reinterpret the contents of
an already filled RegisterValue.  To make this usage work in
all cases (even changing from a type implemented via Scalar
to a type implemented as a byte buffer), SetType now simply
copies the old contents out, and then reloads the RegisterValue
from this data using the new type via SetValueFromData.

This in turn means that there is no remaining caller of
Scalar::SetType, so it can be removed.

The only other follow-on change was in MIPS EmulateInstruction
code, where some uses of RegisterValue::GetBytes could be made
const trivially.
