How to increase  arm_regtrack_max_xrefs in ida.cfg

[Rook 563k iPad Pro (2nd gen) 17.4 Donor]

To do this, head over to: \IDA Pro 7.x\cfg\ida.cfg

And adjust the values here then save.

// for the vars below 0 means "no limit"
ARM_REGTRACK_VALS_SIZE   = 100  // max number of possible values of register
ARM_REGTRACK_OP_RECURS   = 100  // max level of recursion when emulating the execution of instructions
ARM_REGTRACK_BBLK_RECURS = 2000 // max level of recursion when unwinding the execution flow
ARM_REGTRACK_CACHE_SIZE  = 20000// max size of the cache for one register
ARM_REGTRACK_MAX_XREFS   = 256  // max number of xrefs
                                // the ARM module stops tracking registers if it finds more xrefs
