Bananymous 3352640d09 LibC: strlen had to be marked not optimized... 2023-12-19 21:42:59 +02:00
Bananymous 637397dd2f LibC: Make memcpy and memset not optimized

Bananymous c773e2ed07 LibC: Optimize malloc even further
aoc2023/day12 now runs in 3.5 seconds on my machine. This is way
better than the old almost hour.

Bananymous c4186bd5f0 LibC: Compile with -O2 optimizations
I have no idea why libc had no optimizations enabled.

Weird thing is that memcpy optimized to infinite loop if I kept the
__restrict__ attributes in pointers. I don't think there was any ub.

Bananymous 5f640da166 LibC: Optimize malloc by a lot
I now cache first free node in malloc_pool and whether the node is
last or not. There allow doing less full iterations over the whole
malloc pool.

Malloc is still unbearably slow and I will have to write a proper
fast malloc at some point. With this patch running aoc2023/day12 is
atleast possible. Probabaly will take closer to an hour...
