I'm using the GNU Assembler (directly), for Arm Cortex-A system register access (CLUSTERCFR_EL1). ThIS register name is not recognized by the Assembler, so I needed to use register encoding as follows:
mrs X1, S3_0_C15_C3_0 /*. this works */
I want to use a macro or equ with the name "CLUSTERCFR_EL1", but have not been successful. The following does not work:
.equ CLUSTERCFR_EL1, S3_0_C15_C3_0
mrs x1, CLUSTERCFR_EL1
I've also tried enclosing the S3...0 characters with double-quotes, but this also doesn't work.
Tried the following macro definition as well, but it also fails.
.macro CLUSTERCFR_EL1
S3_0_C15_C3_0
.endm
Both the .equ method, and the .macro method fail with:
Error: unknown or missing system register name at operand 2 --
'mrs x1, CLUSTERCFR_EL1'
Any suggestions?
