Johnny Chen e99953ce9c Reverted r99326 which added NVdVmVCVTFrm, and later renamed to NVCVTFrm.
NVCVTFrm will later be used to describe "vcvt with fractional bits".

N3VX instructions using special case code.

Bob Wilson 59f75bba24 Fix VLDMQ and VSTMQ instructions to use the correct encoding and address modes.
These instructions are only needed for codegen, so I've removed all the
explicit encoding bits for now; they should be set in the same way as the for
VLDMD and VSTMD whenever we add encodings for VFP.  The use of addrmode5
requires that the instructions be custom-selected so that the number of
registers can be set in the AM5Opc value.

Johnny Chen 8f3004cff2 Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm

We also changed the output of the addressing modes to omit the '+' from the

Johnny Chen 3d9327bd06 Initial ARM/Thumb disassembler check-in. It consists of a tablgen backend
(RISCDisassemblerEmitter) which emits the decoder functions for ARM and Thumb,
and the disassembler core which invokes the decoder function and builds up the
MCInst based on the decoded Opcode.

Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm
instructions to help disassembly.

We also changed the output of the addressing modes to omit the '+' from the
assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

Chris Lattner b8a7427636 fix a bunch of partially ambiguous patterns on ARM. As an
example, this:

(set DPR:$dst, (fsub (fneg (fmul DPR:$a, DPR:$b)), DPR:$dstin))

is ambiguous because DPR contains both f64 and v2f32.  tblgen
currently accidentally picks f64 because it's first in the 
regclass.

Bob Wilson cb2deb2aaf Remove the NEON N2VSInt instruction class: it's only used in one place and
since it has no pattern, there's not much point in distinguishing an "N2VS"
class for intrinsics anyway.

llvm-svn: 96525
2010-02-17 22:42:54 +00:00
Bob Wilson 004d280d5e More cleanup for NEON:
* Use "S" abbreviation for scalar single FP registers in class and pattern
names, instead of keeping the "D" (for "double") abbreviation and tacking on
an "s" elsewhere in the name.
* Move the scalar single FP register classes and patterns to be more
consistent with other definitions in the file.
* Rename "VNEGf32d" definition to "VNEGfd" for consistency.
* Deleted the N2VDIntsPat pattern; N2VSPat is good enough.

Bob Wilson 9349437c65 The Neon "vtst" instruction takes a suffix that is the element size alone --

Bob Wilson 32cd8550ce Add support for Neon VEXT (vector extract) shuffles.
This is derived from a patch by Anton Korzh.  I modified it to recognize

Bob Wilson eb54d51759 Create a new ARM-specific DAG node, VDUP, to represent a splat from a

Bob Wilson cce31f6831 During legalization, change Neon vdup_lane operations from shuffles to

of with custom code in ARMISelDAGToDAG.cpp.

Bob Wilson 12842f9865 Use vAny type to get rid of Neon intrinsics that differed only in whether

Most of these operations actually depend on the element type, so bitcasting

If you include the vpadd intrinsics that I updated earlier, this gets rid
of 20 intrinsics.
