Joey Gouly df68600f44 [ARMv8] Add support for the NEON instructions vmaxnm/vminnm.
This adds a new class for non-predicable NEON instructions and a
new DecoderNamespace for v8 NEON instructions.

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. =]

Eric Christopher 6ac277ce91 Remove getARMRegisterNumbering and replace with calls into
the register info for getEncodingValue. This builds on the
small patch of yesterday to set HWEncoding in the register
file.

One (deprecated) use was turned into a hard number to avoid
needing register info in the old JIT.

Jakob Stoklund Olesen 6a2e99a46a Deduplicate ARM call-related instructions.
We had special instructions for iOS because r9 is call-clobbered, but
that is represented dynamically by the register mask operands now, so
there is no need for the pseudo-instructions.

Jim Grosbach 7b811d30d9 ARM BL/BLX instruction fixups should use relocations.
We on the linker to resolve calls to the appropriate BL/BLX instruction
to make interworking function correctly. It uses the symbol in the
relocation to do that, so we need to be careful about being too clever.

To enable this for ARM mode, split the BL/BLX fixup kind off from the
unconditional-branch fixups.

Jim Grosbach 46dd413991 ARM clean up the imm_sr operand class representation.
Represent the operand value as it will be encoded in the instruction. This

thumb shift instructions.

Jim Grosbach d359571120 ARM refactoring assembly parsing of memory address operands.
Memory operand parsing is a bit haphazzard at the moment, in no small part
due to the even more haphazzard representations of memory operands in the .td
files. Start cleaning that all up, at least a bit.

The addressing modes in the .td files will be being simplified to not be
so monolithic, especially with regards to immediate vs. register offsets
and post-indexed addressing. addrmode3 is on its way with this patch, for
example.

This patch is foundational to enable going back to smaller incremental patches
for the individual memory referencing instructions themselves. It does just
enough to get the basics in place and handle the "make check" regression tests
we already have.

Follow-up work will be fleshing out the details and adding more robust test
cases for the individual instructions, starting with ARM mode and moving from
there into Thumb and Thumb2.

Jim Grosbach 03f56d9de6 ARM parsing and encoding of SBFX and UBFX.
Encode the width operand as it encodes in the instruction, which simplifies
the disassembler and the encoder, by using the imm1_32 operand def. Add a

the range [1,32-lsb].

Jim Grosbach d2659138da ARM cleanup of rot_imm encoding.
Start of cleaning this up a bit. First step is to remove the encoder hook by
storing the operand as the bits it'll actually encode to so it can just be
directly used. Map it to the assembly source values 8/16/24 when we print it.

Jason W Kim d2e2f56c36 Teach ARM/MC/ELF to handle R_ARM_JUMP24 relocation type for conditional jumps.
(yes, this is different from R_ARM_CALL)

- Adds a new method getARMBranchTargetOpValue() which handles the
  necessary distinction between the conditional and unconditional br/bl
  needed for ARM/ELF

At least for ARM mode, the needed fixup for conditional versus unconditional
br/bl is identical, but the ARM docs and existing ARM tools expect this
reloc type...

Added a few FIXME's for future naming fixups in ARMInstrInfo.td

Evan Cheng 965b3c7323 Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step
in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

2010-12-14 22:28:03 +00:00
Bill Wendling 092a7bdf9f The tLDR et al instructions were emitting either a reg/reg or reg/imm
instruction based on the t_addrmode_s# mode and what it returned. There is some
obvious badness to this. In particular, it's hard to do MC-encoding when the
instruction may change out from underneath you after the t_addrmode_s# variable
is finally resolved.

The solution is to revert a long-ago change that merged the reg/reg and reg/imm
versions. There is the addition of several new addressing modes. They no longer
have extraneous operands associated with them. I.e., if it's reg/reg we don't
have to have a dummy zero immediate tacked on to the SDNode.

There are some obvious cleanups here, which will happen shortly.

Owen Anderson 578074b2f3 In Thumb2, direct branches can be encoded as either a "short" conditional branch with a null predicate, or
as a "long" direct branch.  While the mnemonics are the same, they encode the branch offset differently, and
the Darwin assembler appears to prefer the "long" form for direct branches.  Thus, in the name of bitwise
equivalence, provide encoding and fixup support for it.
