|
; We use the term "base address" since that's what Knuth uses. The base
|
| 68 |
|
|
; address goes in a global register. When addressing, it's more like
|
| 69 |
|
|
; "base address plus offset", with the offset being 0..255 from the base,
|
| 70 |
|
|
; which itself can be a symbol plus an offset. The effect is like having
|
| 71 |
|
|
; a constant pool in global registers, code offsetting from those
|
| 72 |
|
|
; registers (automatically causing a request for a suitable constant base
|
| 73 |
|
|
; address register) without having to know the specific register or the
|
| 74 |
|
|
; specific offset. The setback is that there's a limited number of
|
| 75 |
|
|
; registers, and you'll not find out until link time whether you
|
| 76 |
|
|
; should have compiled with -mno-base-addresses.
