*** 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.

We were checking for integer types only before this. So I added the ability for CompilerType objects to check for integer and enum types.
Then I searched for places that were using the CompilerType::IsIntegerType(...) function. Many of these places also wanted to be checking for enumeration types as well, so I have fixed those places. These are in the ABI plug-ins where we are figuring out which arguments would go in where in regisers/stack when making a function call, or determining where the return value would live. The real fix for this is to use clang to compiler a CGFunctionInfo and then modify the code to be able to take the IR and a calling convention and have the backend answer the questions correctly for us so we don't need to create a really bad copy of the ABI in each plug-in, but that is beyond the scope of this bug fix.
Also added a test case to ensure this doesn't regress in the future.

The CL causes a build breakage on platforms where sizeof(double) == sizeof(long double)
and it incorrectly assumes that sizeof(double) and sizeof(long double) is the same
on the host and the target.

SUMMARY:
- PrepareTrivialCall() to setup register r25 with the address of function to be called.
- RegisterIsCalleeSaved() to use name of a register instead of its byte_offset.

SUMMARY:
This patch includes:
1. Emulation of prologue/epilogue and branch instructions for microMIPS.
2. Setting up alternate disassembler (to be used for microMIPS).
So there will be two disassembler instances, one for microMIPS and other for MIPS.
Appropriate disassembler will be used based on the address class of instruction address.
3. Some of the branch instructions does not have fixed sized delay slot, that means delay slot instruction can be of 2-byte or 4-byte.
For this "m_next_inst_size" has been introduced which stores the size of next instruction (i.e size of delay slot instruction in case of branch).
This can be used wherever the size of next instruction is required.
4. A minor change to use mips32 register names instead of mips64 names.

"gcc" register numbers are now correctly referred to as "ehframe"
register numbers. In almost all cases, ehframe and dwarf register
numbers are identical (the one exception is i386 darwin where ehframe
regnums were incorrect).
The old "gdb" register numbers, which I incorrectly thought were
stabs register numbers, are now referred to as "Process Plugin"
register numbers. This is the register numbering scheme that the
remote process controller stub (lldb-server, gdbserver, core file
support, kdp server, remote jtag devices, etc) uses to refer to the
registers. The process plugin register numbers may not be contiguous
- there are remote jtag devices that have gaps in their register
numbering schemes.
I removed all of the enums for "gdb" register numbers that we had
in lldb - these were meaningless - and I put LLDB_INVALID_REGNUM
in all of the register tables for the Process Plugin regnum slot.
This change is almost entirely mechnical; the one actual change in
here is to ProcessGDBRemote.cpp's ParseRegisters() which parses the
qXfer:features:read:target.xml response. As it parses register
definitions from the xml, it will assign sequential numbers as the
eRegisterKindLLDB numbers (the lldb register numberings must be
sequential, without any gaps) and if the xml file specifies register
numbers, those will be used as the eRegisterKindProcessPlugin
register numbers (and those may have gaps). A J-Link jtag device's
target.xml does contain a gap in register numbers, and it only
specifies the register numbers for the registers after that gap.
The device supports many different ARM boards and probably selects
different part of its register file as appropriate.

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.

for eh_frame and stabs register numberings. This is not
complete but it's a step in the right direction. It's almost
entirely mechanical.
lldb informally uses "gcc register numbering" to mean eh_frame.
Why? Probably because there's a notorious bug with gcc on i386
darwin where the register numbers in eh_frame were incorrect.
In all other cases, eh_frame register numbering is identical to
dwarf.
lldb informally uses "gdb register numbering" to mean stabs.
There are no official definitions of stabs register numbers
for different architectures, so the implementations of gdb
and gcc are the de facto reference source.
There were some incorrect uses of these register number types
in lldb already. I fixed the ones that I saw as I made
this change.
This commit changes all references to "gcc" and "gdb" register
numbers in lldb to "eh_frame" and "stabs" to make it clear
what is actually being represented.
lldb cannot parse the stabs debug format, and given that no
one is using stabs any more, it is unlikely that it ever will.
A more comprehensive cleanup would remove the stabs register
numbers altogether - it's unnecessary cruft / complication to
all of our register structures.
In ProcessGDBRemote, when we get register definitions from
the gdb-remote stub, we expect to see "gcc:" (qRegisterInfo)
or "gcc_regnum" (qXfer:features:read: packet to get xml payload).
This patch changes ProcessGDBRemote to also accept "ehframe:"
and "ehframe_regnum" from these remotes.
I did not change GDBRemoteCommunicationServerLLGS or debugserver
to send these new packets. I don't know what kind of interoperability
constraints we might be working under. At some point in the future
we should transition to using the more descriptive names.
Throughout lldb we're still using enum names like "gcc_r0" and "gdb_r0",
for eh_frame and stabs register numberings. These should be cleaned
up eventually too.
The sources link cleanly on macosx native with xcode build. I
don't think we'll see problems on other platforms but please let
me know if I broke anyone.
