Duncan P. N. Exon Smith a72c6e25ec Hexagon: Remove implicit ilist iterator conversions, NFC
There are two things out of the ordinary in this commit.  First, I made
a loop obviously "infinite" in HexagonInstrInfo.cpp.  After checking if
an instruction was at the beginning of a basic block (in which case,
`break`), the loop decremented and checked the iterator for `nullptr` as
the loop condition.  This has never been possible (the prev pointers are
always been circular, so even with the weird ilist/iplist
implementation, this isn't been possible), so I removed the condition.

Second, in HexagonAsmPrinter.cpp there was another case of comparing a
`MachineBasicBlock::instr_iterator` against `MachineBasicBlock::end()`
(which returns `MachineBasicBlock::iterator`).  While not incorrect,
it's fragile.  I switched this to `::instr_end()`.

All that said, no functionality change intended here.

Colin LeMahieu fc52c11d80 [Hexagon] Adding functionality for duplexing. Duplexing is a way to compress commonly used pairs of instructions in order to reduce code size. The test case duplex.ll normally would be 8 bytes, assign register to 0 and jump to link register. After duplexing this is only 4 bytes. This also tests the HexagonMCShuffler code path which is used to make sure duplexed instructions still follow slot requirements.

Chandler Carruth d48cdbf0c3 Put the functionality for printing a value to a raw_ostream as an
operand into the Value interface just like the core print method is.
That gives a more conistent organization to the IR printing interfaces
-- they are all attached to the IR objects themselves. Also, update all
the users.

This removes the 'Writer.h' header which contained only a single function
declaration.

Chandler Carruth 9aca918df9 Move the LLVM IR asm writer header files into the IR directory, as they
are part of the core IR library in order to support dumping and other
basic functionality.

Rename the 'Assembly' include directory to 'AsmParser' to match the
library name and the only functionality left their -- printing has been
in the core IR library for quite some time.

Update all of the #includes to match.

All of this started because I wanted to have the layering in good shape
before I started adding support for printing LLVM IR using the new pass
infrastructure, and commandline support for the new pass infrastructure.

Chandler Carruth 9fb823bbd4 Move all of the header files which are involved in modelling the LLVM IR
into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.

There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.

The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.

I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).

I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

Chandler Carruth ed0881b2a6 Use the new script to sort the includes of every file under lib.
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

Jack Carter 5e69cffed5 There are a number of generic inline asm operand modifiers that
up to r158925 were handled as processor specific. Making them 
generic and putting tests for these modifiers in the CodeGen/Generic
directory caused a number of targets to fail. 

This commit addresses that problem by having the targets call 
the generic routine for generic modifiers that they don't currently
have explicit code for.

For now only generic print operands 'c' and 'n' are supported.vi


Affected files:

    test/CodeGen/Generic/asm-large-immediate.ll
    lib/Target/PowerPC/PPCAsmPrinter.cpp
    lib/Target/NVPTX/NVPTXAsmPrinter.cpp

MSP430 isn't represented because it did not even run with
the long existing 'c' modifier and it was not apparent what
needs to be done to get it inline asm ready.

regression test suite passes. Never submit a patch without running the
regression test suite.

Chandler Carruth b415bf98f0 This reverts a long string of commits to the Hexagon backend. These
commits have had several major issues pointed out in review, and those
issues are not being addressed in a timely fashion. Furthermore, this
was all committed leading up to the v3.1 branch, and we don't need piles
of code with outstanding issues in the branch.

It is possible that not all of these commits were necessary to revert to
get us back to a green state, but I'm going to let the Hexagon
maintainer sort that out. They can recommit, in order, after addressing
the feedback.

Reverted commits, with some notes:

Primary commit r154616: HexagonPacketizer
  - There are lots of review comments here. This is the primary reason
    for reverting. In particular, it introduced large amount of warnings
    due to a bad construct in tablegen.
  - Follow-up commits that should be folded back into this when
    reposting:
    - r154622: CMake fixes
    - r154660: Fix numerous build warnings in release builds.
  - Please don't resubmit this until the three commits above are
    included, and the issues in review addressed.

Primary commit r154695: Pass to replace transfer/copy ...
  - Reverted to minimize merge conflicts. I'm not aware of specific
    issues with this patch.

Primary commit r154703: New Value Jump.
  - Primarily reverted due to merge conflicts.
  - Follow-up commits that should be folded back into this when
    reposting:
    - r154703: Remove iostream usage
    - r154758: Fix CMake builds
    - r154759: Fix build warnings in release builds
  - Please incorporate these fixes and and review feedback before
    resubmitting.

Primary commit r154829: Hexagon V5 (floating point) support.
  - Primarily reverted due to merge conflicts.
  - Follow-up commits that should be folded back into this when
    reposting:
    - r154841: Remove unused variable (fixing build warnings)

There are also accompanying Clang commits that will be reverted for
consistency.
