Second try of initial ARM/Thumb disassembler check-in. It consists of a tablgen backend (ARMDecoderEmitter) 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. Reviewed by Chris Latter and Bob Wilson. llvm-svn: 100233

Multiclass LdStCop was using pre-UAL syntax LDC<c>L for the L fragment. Changed to the UAL syntax of LDCL<c>, instead. Add a test case for this change which also tests the removal of assert() from printAddrMode2OffsetOperand(). llvm-svn: 101527

Fixed a bug in ARM disassembly where LDRSBT should have am3offset operand, not am2offset. Modified the instruction table entry and added a new test case. llvm-svn: 101415

Fixed a crasher in arm disassembler within ARMInstPrinter.cpp after calling ARM_AM::getSoImmVal(V) with a legitimate so_imm value: #245 rotate right by 2. Introduce ARM_AM::getSOImmValOneOrNoRotate(unsigned Arg) which is called from ARMInstPrinter.cpp's printSOImm() function, replacing ARM_AM::getSOImmVal(V).
