Struct Teb 

pub struct Teb {
    pub index: &'static str,
    pub array: &'static str,
    pub block: &'static str,
}

The instructions a thread-local variable is reached with on Windows on AArch64.

The same walk as Indexed, from the TEB Windows keeps in x18 rather than in a segment, and the six instructions clang writes for it.

adrp x8, _tls_index
ldr  w8, [x8, :lo12:_tls_index]
ldr  x9, [x18, #88]
ldr  x8, [x9, x8, lsl #3]
add  x8, x8, :secrel_hi12:x, lsl #12
add  x0, x8, :secrel_lo12:x

Fields

index: &'static str

The first two, which read _tls_index, carrying it as its symbol.

array: &'static str

The third, which reads the array out of the TEB.

block: &'static str

The rest, which read this thread’s block out of the array with the index and add the variable’s offset in its section, carrying the variable as its symbol. It takes the array and the index as its two sources, in that order.
