Second of a three-patch series aiming to fix MSR/MRS on Cortex-M. This adds predicate checking to the Disassembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139250 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100233 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134902 91177308-0d34-0410-b5e6-96231b3b80d8

# CHECK: addpl r4, pc, #318767104
ADR was added with the wrong encoding for inst{24-21}, and the ARM decoder was fooled. 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128234 91177308-0d34-0410-b5e6-96231b3b80d8

There were two issues fixed: 1. The ARM Darwin *r9 call instructions were pseudo-ized recently. Modify the ARMDisassemblerCore.cpp file to accomodate the change. 2. The disassembler was unnecessarily adding 8 to the sign-extended imm24: imm32 = SignExtend(imm24:'00', 32); // A8.6.23 BL, BLX (immediate) // Encoding A1 It has no business doing such. Removed the offending logic. Add test cases to arm-tests.txt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127707 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136845 91177308-0d34-0410-b5e6-96231b3b80d8

ARM instructions that are both predicated and set the condition codes have been printed with the "S" modifier after the predicate. With ARM's unified syntax, they are supposed to go in the other order. We fixed this for Thumb when we switched to unified syntax but missed changing it for ARM. Apparently we don't generate these instructions often because no one noticed until now.
