Bug Description
Hi i am using the ARM v8 cores (a57 and a 53 ) and the GIC 500 ,
My GCC version is - 4.7.3-0.
I am trying to read /write to the ICC_* system registers which are GIC related while using the MSR/MRS commands and getting compilation error that the compiler doesn't recognize these registers as system registers .
an example for such a register is - ICC_IAR1_EL1
is this a bug or am i doing something wrong?
