Tweak handling of IT blocks a bit to enable this. The differentiation between
B and Bcc needs special sauce.

Craig Topper 94ce535647 Make IC_VEX* not inherit from IC_*. Prevents instructions with no VEX form from disassembling to their non-VEX form. Also prevents weak filter collisons that were keeping valid VEX instructions from decoding properly. Make VEX_L* not inherit from VEX_* because the VEX.L bit always important. This stops packed int VEX encodings from being disassembled when specified with VEX.L=1. Fixes PR10831 and PR10806.

Owen Anderson 16d33f36d5 invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons. We were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts. Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits. This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure.

Evan Cheng eee864520c Some autoconf tests use module level inline asm to test compiler's handling of
.cfi_startproc. e.g. libffi:

 $ cat confopt.c 
asm (".cfi_startproc\n\t.cfi_endproc");

int main () { return 0; }

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.

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.

Kevin Enderby 5ef6c453a6 Fix llvm-mc handing of x86 instructions that take 8-bit unsigned immediates.
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.

The .local, .hidden, .internal, and .protected are not legal for all supported
file formats (in particular, they're invalid for MachO). Move the parsing for
them into the ELF assembly parser since that's the format they're for.
Similarly, .weak is used by COFF and ELF, but not MachO, so move the parsing
to the COFF and ELF asm parsers. Previously, using any of these directives
on Darwin would result in an assertion failure in the parser; now we get
a diagnostic as we should.

Jim Grosbach 581da64241 Simplify printing of ARM shifted immediates.
Print shifted immediate values directly rather than as a payload+shifter
value pair. This makes for more readable output assembly code, simplifies
the instruction printer, and is consistent with how Thumb immediates are
 displayed.

Evan Cheng c5e6d2f519 - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfo
and MCSubtargetInfo.
- Added methods to update subtarget features (used when targets automatically
  detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
  MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
  MCSubtargetInfo so MC code emitter can do the right thing.

Jim Grosbach 76346c3bf7 Asm parser range checking on .<size> <value> directives.
For example, ".byte 256" would previously assert() when emitting an object

When the destination operand is the same as the first source register
operand for arithmetic instructions, the destination operand may be omitted.

Jim Grosbach a6f7a1efcc ARM Assembly support for Thumb mov-immediate.
Correctly parse the forms of the Thumb mov-immediate instruction:
  1. 8-bit immediate 0-255.
  2. 12-bit shifted-immediate.

The 16-bit immediate "movw" form is also legal with just a "mov" mnemonic,
but is not yet supported. More parser logic necessary there due to fixups.
