Subject: [PATCH] terminal: fix tile-offset calculation
|
|
|
|
Binary operators with two pointers as arguments always operate on
|
|
object-size, not bytes. That is, "int *a, *b", (a - b) calculates the
|
|
number of integers between b and a, not the number of bytes.
|
|
|
|
Fix our cache-offset calculation to not use sizeof() with full-ptr
|
|
arithmetic.
