undef mask elements. This fixes PR10529.

llvm-svn: 136450

Also tidy up code a bit.

llvm-svn: 136449

Also make PALIGNR masks to don't match 256-bits, which isn't supported
It's also a step to solve PR10489

Later passes /are/ using this information when running the register
scavenger.

This fixes the second problem in PR10520.

llvm-svn: 136440

This hidden llc option runs the machine code verifier after expanding
ARM pseudo-instructions, but before if-conversion.

The machine code verifier is much better at pointing out liveness errors
that can trip up the register scavenger.

specified in the same file that the library itself is created. This is
more idiomatic for CMake builds, and also allows us to correctly specify
dependencies that are missed due to bugs in the GenLibDeps perl script,
or change from compiler to compiler. On Linux, this returns CMake to
a place where it can relably rebuild several targets of LLVM.

I have tried not to change the dependencies from the ones in the current
auto-generated file. The only places I've really diverged are in places
where I was seeing link failures, and added a dependency. The goal of
this patch is not to start changing the dependencies, merely to move
them into the correct location, and an explicit form that we can control
and change when necessary.

This also removes a serialization point in the build because we don't
have to scan all the libraries before we begin building various tools.
We no longer have a step of the build that regenerates a file inside the
source tree. A few other associated cleanups fall out of this.

This isn't really finished yet though. After talking to dgregor he urged
switching to a single CMake macro to construct libraries with both
sources and dependencies in the arguments. Migrating from the two macros
to that style will be a follow-up patch.

Also, llvm-config is still generated with GenLibDeps.pl, which means it
still has slightly buggy dependencies. The internal CMake
'llvm-config-like' macro uses the correct explicitly specified
dependencies however. A future patch will switch llvm-config generation
(when using CMake) to be based on these deps as well.

This may well break Windows. I'm getting a machine set up now to dig
into any failures there. If anyone can chime in with problems they see
or ideas of how to solve them for Windows, much appreciated.

Add parsing support for BLX (immediate). Since the register operand version is
predicated and the label operand version is not, we have to use some special
handling to get the operand list right for matching.

llvm-svn: 136406

Add parsing support that handles converting the lsb+width source into the
odd way we represent the instruction (an inverted bitfield mask).

Revert r136295.  It broke nightly testers because some parts of codegen weren't aware of the changes to operand ordering.  I hope to revive this sometime in the future, but it's not strictly necessary for now.

The label does not have a '#' prefix. Add parsing and encoding tests.

LLVM*AsmPrinter.

GenLibDeps.pl fails to detect vtable references. As this is the only
referenced symbol from LLVM*Desc to LLVM*AsmPrinter on optimized
builds, the algorithm that creates the list of libraries to be linked
into tools doesn't know about the dependency and sometimes places the
libraries on the wrong order, yielding error messages like this:

../../lib/libLLVMARMDesc.a(ARMMCTargetDesc.cpp.o): In function
`llvm::ARMInstPrinter::ARMInstPrinter(llvm::MCAsmInfo const&)':
ARMMCTargetDesc.cpp:(.text._ZN4llvm14ARMInstPrinterC1ERKNS_9MCAsmInfoE

Take advantage that the 128-bit vpxor zeros the higher part and use it.

Refactor and improve the encodings/decodings for addrmode3 loads, and make the writeback operand always the first.

llvm-svn: 136295

This can happen in cases where TableGen generated asm matcher cannot check
whether a register operand is in the right register class. e.g. mem operands.

llvm-mc gives an "invalid operand" error for instructions that take an unsigned
immediate which have the high bit set such as:
    pblendw $0xc5, %xmm2, %xmm1
llvm-mc treats all x86 immediates as signed values and range checks them.
A small number of x86 instructions use the imm8 field as a set of bits.
This change only changes those instructions and where the high bit is not
ignored.  The others remain unchanged.

llvm-svn: 136287

Use range checked immediate operands for instructions. Add tests.

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
diagnostic for the context-sensitive constraint that the width must be in
the range [1,32-lsb].

llvm-svn: 136264

Refactor the STRT and STRBT instructions to distinguish between the register-addend and immediate-addend versions.  Temporarily XFAIL the asm parsing tests for these instructions.

llvm-svn: 136255

This adds the new instructions 'landingpad' and 'resume'.

Assembly parser handling for extend instruction rotate operands. Add tests
for the sign extend instructions.

X86ISD::MEMBARRIER does not require SSE2; it doesn't actually generate any code, and all x86 processors will honor the required semantics.

llvm-svn: 136249

llvm-svn: 136229

Refactor the rest of the extend instructions to not artificially distinguish
between a rotate of zero and a rotate of any other value. Replace the by-zero
versions with Pat<>'s for ISel.

llvm-svn: 136226

Refactor the SXTB, SXTH, SXTB16, UXTB, UXTH, and UXTB16 instructions to not
have an 'r' and an 'r_rot' version, but just a single version with a rotate
that can be zero. Use plain Pat<>'s for the ISel of the non-rotated version.

usage of the shuffle bitmask. Both work in 128-bit lanes without
