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.
