* This branch contains support for new architectures. * Initial start to support for AArch 32 * Progress * Forgot the new files * Added all data Integer processing instructions without S + ADDS and started ANDS * Updated * Finished Integer Data Processing with three registers, added integer data processing with 2 regs + immediate, started MUL instructions * UMULL, UMULLS, UMLAL, UMLALS * Corrected condition for addend or 0 immediate for UMULL/UMLAL + SMULL/SMLAL instructions * Correct ops in Binary.cpp * UMAAL * SMULL, SMULLS, SMLAL, SMLALS + corrected acc was missing shift left in concatination * Updated decoding instructions based on top level encodings * Update returns around kDataProcessingRI and kDataProcessingI with comments to explain the correlation to the instruction rep * Added appropriate inst.category flags to Multiply and accumulate * Load/Store Word, Unsigned Byte (immediate, literal) && start of Logical Arithmetic (three register, immediate shift) * Was missing UMAAL DEF_ISEL in Binary.cpp * AddAddrRegOp * Logical Arithmetic (three register, immediate shift) without accounting for the possible PC jump * Made DecodeA32ExpandImm much much smaller * Replaced some imm ops with AddImmOp calls * Created AddShiftOp * Added interpreter for evaluating new PC value at decoding time to handle direct jumps and conditional jumps * Created EvalPCDest added PC evaluation to Logical Arithmetic Instructions * AddShiftOp -> AddShiftOp, AddShiftThenExtractOp, AddExtractThenShiftOp * Cleaned up some formatting, Renamed DecodeA32ExpandImm to ExpandTo32AddImmAddCarry and added a clarifying comment * Added comment to EvalPCDest for clarity * Cleaned up some things, updated the decoding semantics and semantics for the logical instructions * Shortened kLogArithEvaluators and fixed a bug * Updates from testing instructions * Fixed DEF_ISEL for pre/post index instructions in MEM.cpp * Integer Test and Compare (two register, immediate shift) * Logical Arithmetic (two register and immediate) * Integer Test and Compare (one register and immediate) * Added to the top level encoding infrastructure to handle the Data-processing register (register shift) set of instructions and 3 corresponding subsets * Add structs for the 3 subsets of Data-processing register (register shift) * Code status before refactoring operand types * This

(register shift) set of instructions and 3 corresponding subsets * Add structs for the 3 subsets of Data-processing register (register shift) * Code status before refactoring operand types * Finished updates off master * Start of operand refactor * Finished Expression Operand Support * Fix the .gitignore to add AArch32 to lib/Arch && removed all extra rrx ops from semantics * Updated .gitignore again, Added AddShiftRegRegOperand, Updated AddShiftRegImmOperand, Finished Register shift instructions for Integer Test and Compare, Logical Arithmetic, Integer Data Processing * Updated ROR in AddShiftRegRegOperand * Created ExtractAndZExtExpr * Fixed comment formatting in if else statements * Created RORExpr * Small fixes * Small fix in Logical Arithmetic (two register and immediate) * Corrected AddShiftRegRegOperand and cleaned it up. Split the carry op into a separate function. * conditional support + Start of Branch instructions * Created AddExprOp, cleaned up some expressions in reg shifted reg, and updated some occurances of ShiftThenExtractOp with ExtractAndZExtExpr * Updates from testing register shifted by register value inst * Fix to ROR in AddShiftRegCarryOperand * Corrected negation in DecodeCondition * DecodeCondition edit * DecodeCondition and AddShiftRegCarryOperand edits * Updated arch_for_decode to arch * Halfword Multiply and Accumulate * Edits from testing Halfword Multiply and Accumulate * Changed order of operands in Halfword Multiply and Accumulate to better reflect inst format + updated inst errors * Branch (Imm) & BX/BXL * Update aarch32 cmake * cmake update * CLZ * Forgot BITBYTE.cpp * MOVT * Integer Saturating Arithmetic * updated semantics in SMLAWh & SMLAh to use Select for setting PSTATE.Q * Started Load/Store Word, Unsigned Byte (register) & fixed MOV halfword * Load/Store Word, Unsigned Byte (register) * Finished testing load/Store Word, Unsigned Byte (register) * Load/Store Dual, Half, Signed Byte (register) * Rest of Extra load store: Load/Store Dual, Half, Signed Byte (immediate, literal) * Finished testing all the Load/store additions * Signed multiply, Divide * Cleaned up SExt some * Saturate Insts and Start of Load Store Multiple - STMDB and LDM (aliases which support PUSH and POP of multiple regs) * Condensed args in STMDB and LDM semantics * Rest of Multiple Load/Store that do not execute in a different mode * Bitfield Extract * Extend and Add * fix * NOP * Small fix * Simplified the bit reps in TryMoveSpecialRegisterAndHintsI * Moved Bitfield extract semantics out of BINARY and into BITBYTE * Finished correcting S/ZExt and Trunc use * Ran scripts/format-files to format * Smoke Test * Add false delay slot to kCategoryConditionalDirectFunctionCall * CI: Use single packaging job, add changelog support (#491) * CI: Add tag handler (#492) * Delay slot fixes to TraceLifter Co-authored-by: Peter Goodman <peter.goodman@gmail.com> Co-authored-by: Alessandro Gario <5714290+alessandrogario@users.noreply.github.com>
