Hi Arm experts,
I have a load command to load a structure in assembly code as below:
adrp x4,ASM_NAME(forkx)
This load instruction is not giving the proper address of the structure that i have intended: took the gdb trace at this point and following is the details:
1. We can see the register content at the time of load and x4 have 0x55783dd000
(gdb) info registers
x0 0x30a0 12448
x1 0x0 0
x2 0x7fdf1bf6b0 549203998384
x3 0x55ad57f898 367980443800
x4 0x55783dd000 367089537024
x5 0x0 0
x6 0x1 1
2. If i see the forkx address it is:
(gdb) print &forkx$13 = (sprocess * __be *) 0x55783dd5c0 <__be_forkx>
My intention is to load the address 0x55783dd5c0 but it is loading 0x55783dd000. this is causing the issue in the subsequent commands as invalid address is gettig accessed.
Is this is a known behaviour with adrp? do i need to handle this with any other way? Please help me in this. Thanks.
