IDA Pro plugin for arm64 switch tables processing

IDA Pro supports arm64 very poorly - it also cannot parse switch tables. Let`s see how they looks on arm64 - for example in function NtQueryInformationThread:
 CMP             W1, #0x2D           ; check index
 B.HI            loc_140673294
 ADR             X9, dword_14066E9EC ; switch tab address
 LDRSW           X8, [X9,W1,UXTW#2]  ; index in W1 << 2
 ADR             X9, loc_14066E358   ; base address
 ADD             X8, X9, X8,LSL#2    ; base address + offset << 2
 BR              X8
What happens here? first "ADR x9, addr" loads address of switch table
Next LDRSW is like "mov x8, [x9 + 4 * w1]" on Intel - load DWORD at x9 + index w1 left shifted by 2
Then second ADR loads address of base for this switch table
ADD x8, x9, x8 << 2 sets in x8 address of actual jumps
and finally BR go to this address

So I just wrote quick and dirty plugin arm64sw.p64 based on armpatched for switch tables processing
