printing a single character.

Add an assertion to linear scan to prevent it from allocating registers outside
the register class.

llvm-svn: 128254

llvm-svn: 128253

Modify the wrong logic in the assert of DisassembleThumb2LdStDual() (the register classes were changed),
modify the comment to be up-to-date, and add a test case for A8.6.66 LDRD (immediate) Encoding T1.

llvm-svn: 128252

llvm-svn: 128251

llvm-svn: 128250

delegate the disassembly of t2ADR to the more generic t2ADDri12/t2SUBri12 instructions, and add a test case for that.

llvm-svn: 128249

Modified the Disassembler::Instruction base class to contain an Opcode 
instance so that we can know the bytes for an instruction without needing
to keep the data around.

Modified the DisassemblerLLVM's instruction class to correctly extract the
opcode bytes if all goes well.

llvm-svn: 128248

the change to ("tLDMIA", "tLDMIA_UPD").  Update the conflict resolution code and add
test cases for that.

llvm-svn: 128247

According to A8.6.189 STM/STMIA/STMEA (Encoding T1), there's only tSTMIA_UPD available.
Ignore tSTMIA for the decoder emitter and add a test case for that.

These instructions were changed to not embed the addressing mode within the MC instructions
We also need to update the corresponding assert stmt.  Also add a test case.

llvm-svn: 128240

public types and public enums. This was done to keep the SWIG stuff from
parsing all sorts of enums and types that weren't needed, and allows us to
abstract our API better.

llvm-svn: 128239

llvm-svn: 128238

Fix small bug in ThumbExpandImm_C; arguments to a call to 'bits' were
in the wrong order.

llvm-svn: 128237

llvm-svn: 128236

These two are test cases which should result in 'invalid instruction encoding' from running llvm-mc -disassemble.

llvm-svn: 128235

Set the encoding bits to {0,?,?,0}, not 0.  Plus delegate the disassembly of ADR to
the more generic ADDri/SUBri instructions, and add a test case for that.

llvm-svn: 128234

A better approach would be to move source id handling inside MC.

llvm-svn: 128233

Add missing encodings for EmulateLDRRtRnImm (ARM insn emulation funciton).

llvm-svn: 128229

llvm-svn: 128228

The MC asm lexer wasn't honoring a non-default (anything but ';') statement
separator. Fix that, and generalize a bit to support multi-character
statement separators.

llvm-svn: 128227

VORRiv*i* instructions properly within the DisassembleN1RegModImmFrm() function.  Add a test case.

llvm-svn: 128226

llvm-svn: 128224

a test case of invalid CPS3p encoding and one for invalid VLDMSDB due to regs out of range.

void; it doesn't need to have a void type.

llvm-svn: 128211

Minor fix in the injection of labels, since we want to look at the redeclaration context of each declaration in the identifier chain. Should fix Linux self-host

llvm-svn: 128210

AttributeLists do not accumulate over the lifetime of parsing, but are
instead reused.  Also make the arguments array not require a separate
allocation, and make availability attributes store their stuff in
augmented memory, too.

llvm-svn: 128209

the case where we only have a single identifier with that name in the
chain. Fixes PR9463 for real this time.

llvm-svn: 128208

FIXME: Some cleanups would be needed.
