Fix Bug 20400

Summary:
http://llvm.org/bugs/show_bug.cgi?id=20400

The default triple of i686-pc-linux-gnu for 32 bit linux targets is compatible
but not necessarily identical to the inferior binaries.

Applying Azat Khuzhin's solution of using ArchSpec::IsCompatibleMatch() instead
of ArchSpec::IsExactMatch() when comparing ObjectFile and Modules architecture.

Start converting usages of off_t to other types.

2014-07-02T17:24:07+00:00

off_t is a type which is used for file offsets.  Even more
specifically, it is only used by a limited number of C APIs that
deal with files.  Any usage of off_t where the variable is not
intended to be used with one of these APIs is a bug, by definition.

This patch corrects some easy mis-uses of off_t, generally by
converting them to lldb::offset_t, but sometimes by using other
types such as size_t, when appropriate.

The use of off_t to represent these offsets has worked fine in
practice on linux-y platforms, since we used _FILE_OFFSET_64 to
guarantee that off_t was a uint64.  On Windows, however,
_FILE_OFFSET_64 is unrecognized, and off_t will always be 32-bit.
So the usage of off_t on Windows actually leads to legitimate bugs.

iOS simulator cleanup to make sure we use "*-apple-ios" for iOS simulator apps and binaries.

2014-05-29T21:33:45+00:00

Changes include:
- ObjectFileMachO can now determine if a binary is "*-apple-ios" or "*-apple-macosx" by checking the min OS and SDK load commands
- ArchSpec now says "-apple-macosx" is equivalent to "-apple-ios" since the simulator mixes and matches binaries (some from the system and most from the iOS SDK).
- Getting process inforamtion on MacOSX now correctly classifies iOS simulator processes so they have "*-apple-ios" architectures in the ProcessInstanceInfo
- PlatformiOSSimulator can now list iOS simulator processes correctly instead of showing nothing by using:
    (lldb) platform select ios-simulator
    (lldb) platform process list
- debugserver can now properly return "*-apple-ios" for the triple in the process info packets for iOS simulator executables
- GDBRemoteCommunicationClient now correctly passes along the triples it gets for process info by setting the OS in the llvm::Triple correctly

Fixed the Module::Module(ModuleSpec) constructor to properly copy the file offset and object file mod time from the actual module specifications so we will always be able to directly load the image we care about when calling Module::GetObjectFile().

sweep up -Wformat warnings from gcc

2014-04-04T04:06:10+00:00

This is a purely mechanical change explicitly casting any parameters for printf
style conversion.  This cleans up the warnings emitted by gcc 4.8 on Linux.

lldb arm64 import.

These changes were written by Greg Clayton, Jim Ingham, Jason Molenda.

It builds cleanly against TOT llvm with xcodebuild.  I updated the
cmake files by visual inspection but did not try a build.  I haven't
built these sources on any non-Mac platforms - I don't think this
patch adds any code that requires darwin, but please let me know if
I missed something.

In debugserver, MachProcess.cpp and MachTask.cpp were renamed to
MachProcess.mm and MachTask.mm as they picked up some new Objective-C
code needed to launch processes when running on iOS.

Add a GetFoundationVersion() to AppleObjCRuntime
This API is used to return and cache the major version of Foundation.framework, which is potentially a useful piece of data to key off of to enable or disable certain ObjC related behaviors (especially in data formatters)

JITed functions can now have debug info and be debugged with debug and source info:

2014-03-24T23:10:19+00:00

(lldb) b puts
(lldb) expr -g -i0 -- (int)puts("hello")

First we will stop at the entry point of the expression before it runs, then we can step over a few times and hit the breakpoint in "puts", then we can continue and finishing stepping and fininsh the expression.

Main features:
- New ObjectFileJIT class that can be easily created for JIT functions
- debug info can now be enabled when parsing expressions
- source for any function that is run throught the JIT is now saved in LLDB process specific temp directory and cleaned up on exit
- "expr -g --" allows you to single step through your expression function with source code
