0797e69106 Add all optimisations done on line_down to line_down_inv. DIx a problem that the pixel was drawin a bit to late in the loop on line_down. 2025-03-06 01:50:37 +01:00

ecc138f2bc Redused number of instructions but to small a diffrence to messure with current test 2025-03-06 00:59:29 +01:00

76f29f6b81 Performance improvment in test by 0.1s. Mady by better arithmatic for *40 in draw_pixel and fast_unsafe parameter for most macros 2025-03-05 21:02:54 +01:00

982b6c7ea6 A fix for the timer to work by making it start with value 1. It do not increment from 0! 2025-03-05 01:27:37 +01:00

89c2b42bfe Reorginisation of line-drawing code. Also added a macro to benchmark line drawing logic. Addition of line_test_time to benchmark line drawing time (Do not work yet) 2025-03-04 23:01:57 +01:00

494e9dc5f9 A fix of line_up_inv such that X_pos < X_end like all other line_* implementations. 2025-03-04 21:00:21 +01:00

4d12f20a6e A Fix for D that gets the wrong initial value and the branch logic in line_* checked for the wrong value.
A new proc, line.s that can chose whitch line_* to use
A small test program in source.s
Wrote a smal test program in source.s  (all looks good exept line_up_inv)

f3712eca9f Move logic outside loop for performance reasons.
Same as earlier commit but for line_down_inv.s, line_up.s
Comment: Should do the same for line_up_inv.s

ee69828ec7 Optimisation by moving logic out of loop for faster execution.
This should be implemented on the other line_* files

0940d9f9f9 1. A fix for a bug where D gets the wrong initial value (2 bytes where flipped)
2. Implemented line drawing for the other 3 cases

4f396fd740 A fix to a bug, to make line_down draw lines with small slopes.
I needed to use 16bit logic to ashive this.
Also moved out dx*2, dy*2 calculation outside of loop for better performance.
