Error in inline assembly code for AArch64:Unknown identifier VBAR_EL1

[TYDQ]

These days I am developing the AArch64 Interrupt Vector Table for my application.
However,I met these error below when I am using AArch64 inline assembly:

Code: Pascal  [Select][+][-]

1. procedure os_vector_table_initialize;
2. label label1,vector_table;
3. begin
4.  asm
5.   msr DAIFClr,#15 //[0.012] osbase.pas(315,14) Error: Unknown identifier "DAIFCLR"

7.  goto label1;

Does anyone know about the AArch64 inline assembly for Cross-compiling to AArch64 using Free Pascal Compiler for AArch64?
I am exhausted to the correct answer.
