* Add auto-sync updater. * Update Capstone core with auto-sync changes. * Update ARM via auto-sync. * Make changes to arch modules which are introduced by auto-sync. * Update tests for ARM. * Fix build warnings for make * Remove meson.build * Print shift amount in decimal * Patch non LLVM register alias. * Change type of immediate operand to unsiged (due to: #771) * Replace all occurances of a register with its alias. * Fix printing of signed imms * Print rotate amount in decimal * CHange imm type to int64_t to match LLVM imm type. * Fix search for register names, by completing string first. * Print ModImm operands always in decimal * Use number format of previous capstone version. * Correct implicit writes and update_flags according to SBit. * Add missing test for RegImmShift * Reverse incorrect comparision. * Set shift information for move instructions. * Set mem access for all memory operands * Set subtracted flag if offset is negative. * Add flag for post-index memory operands. * Add detail op for BX_RET and MOVPCLR * Use instruction post_index operand. * Add VPOP and VPUSH as unique CS IDs. * Add shifting info for MOVsr. * Add TODOs. * Add in LLVM hardcoded operands to detail. * Move detail editing from InstPrinter to Mapping * Formatting * Add removed check. * Add writeback register and constraints to RFEI instructions. * Translate shift immediate * Print negative immediates * Remove duplicate invalid entry * Add CS groups to instructions * Fix write attriutes of stores. * Add missing names of added instructions * Fix LLVM bug * Add more post_index flags * http -> https * Make generated functions static * Remove tab prefix for alias instructions. * Set ValidateMCOperand to NULL. * Fix AddrMode3Operand operands * Allow getting system and banked register name via API * Add writeback to STC/LDC instructions. * Fix (hopefully) last case where disp is negative and subtracted = true * Remove accidentially introduced regressions
