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 
GCC does some weird optimizations and breaks these functions

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...

Bananymous 00d57d783e LibC+userspace: Make everything compile with -Wall -Wextra -Werror 
I added -Wall -Wextra -Werror as public compile flags to libc. Now
everything in userspace in compiled using these flags. I made all
necessary changes to allow compilation to work.

Only exception is execvp which has a large stack usage. Maybe it
should use malloc for the buffer but posix allows ENOMEM only when
kernel is out of memory... This can be fixed when fexecve is
implemented and there is no need for absolute path.

Bananymous 1c78671078 Kernel: Rework all signal code 
Signal handling code was way too complex. Now everything is
simplified and there is no need for ThreadBlockers.

Only complication that this patch includes is that blocking syscalls
have to manually be made interruptable by signal. There might be some
clever solution to combat this is make this happen automatically.

Bananymous 894065a67e LibC: cleanup and fix fgets 
My quick fix for fgets wrote non-nullterminated newline if size was
one.

POSIX doesn't specify what happens if size == 0, so I do the same as
glibc and return NULL without setting errno.
