This is a bug in GNU Binutils.  These system registers are incorrectly
described as being part of armv8.3-a, rather than part of the Pauth extension. 
Please can you raise a bug there: https://sourceware.org/bugzilla (select
product binutils).

I encountered issues even with the latest version 2.42 of binutils, as shown
below.

~/x-tools/aarch64-unknown-linux-gnu/bin/aarch64-unknown-linux-gnu-as -v
GNU assembler version 2.42 (aarch64-unknown-linux-gnu) using BFD version
(crosstool-NG 1.26.0.72_810021d) 2.42

I am using binutils 2.39.0, GNU assembler version 2.39.0

arm-none-eabi-as -v
GNU assembler version 2.39.0 (arm-none-eabi) using BFD version (Arm GNU
Toolchain 12.2.Rel1 (Build arm-12.24)) 2.39.0.20221210

Could you tell which version fixed it?

This looks like a binutils issue rather a gcc one. It might be already fixed in
binutils too.

Hi Richard:
   thanks for reply.
   here is the test file for pauth, named as test.S:
   align 8
   .global test
   .type test,%function
   test:
mrs x9, apiakeyhi_el1  
mrs x10, apiakeylo_el1
mov x11, lr
mov x12, sp

   when I use "aarch64-none-linux-gnu-gcc -mcpu=cortex-a78ae test.S -o test.o",
gcc generates errors as follows:
   test.S: Assembler messages:
test.S:5: Error: selected processor does not support system register name
'apiakeyhi_el1'
test.S:6: Error: selected processor does not support system register name
'apiakeylo_el1'

   when I use "aarch64-none-linux-gnu-gcc -march=armv8.2-a+pauth -c test.S -o
test.o", gcc generates errors as follows:
   test.S: Assembler messages:
test.S:5: Error: selected processor does not support system register name
'apiakeyhi_el1'
test.S:6: Error: selected processor does not support system register name
'apiakeylo_el1'

   when I use "aarch64-none-linux-gnu-gcc -march=armv8.3-a -c test.S -o
test.o", there is no error generated.

It looks like those messages are coming from the assembler, not the compiler,
but without a testcase it's difficult to be exactly sure what your problem is.

Please attach a small program that demonstrates your problem and state the 
/exact/ command line you used.
