Bananymous 13fabcc1f1 BAN: add pow, log2, log10, log in math 
These are implemented using x86 floating point assembly

Bananymous c2ad76fe4f BAN: Error uses 64 bit error codes 2023-05-07 02:09:52 +03:00
Bananymous 88a2c60065 BAN: Add is_power_of_two to Math functions 2023-04-28 14:42:49 +03:00
Bananymous c5b006bf19 BAN: Add {TRY,MUST}_REF for references 
It is annoying that we have to have separate macros for these but
I can't find a way to cleanly return lvalue reference from statement
expression. Currently we cast the reference to pointer and return
unreference the pointer outside of the expression.

This feature will probably not be used any time soon, but atleas
it is implemented if I need it one day

Bananymous 115c44630d BAN: TRY and MUST macros use rvalue references 2023-04-19 00:11:15 +03:00
Bananymous 1dc81abca4 BAN: Add specialization for ErrorOr<LValueReference> 
ErrorOr can now return a reference :)

Bananymous 5aaf2128a8 BAN: Variant with reference now supports copy/assign 2023-04-18 20:21:23 +03:00
Bananymous 6aeac17072 BAN: Variant now works with references 
References can be assigned with the set() method. Construction nor
assigment operators cannot be used with references to avoid ambiguity
with what assignment to reference does.

You can set the underlying reference with the set() method and access
it with the get() method.

The references are stored as pointers to the object under the hood
which means that size of a reference is sizeof pointer.

Bananymous 0ee7da92a3 BAN: Variant now aligns its data properly 2023-04-12 00:17:45 +03:00
Bananymous 8d6db168d6 Kernel: remove message from BAN::Error 
We don't store the error message anymore in BAN::Error.
Instead we store a error code that can be mapped into a string.
This allows BAN::Error to only take 4 bytes instead of 128.

We should also make some kernel initialization just panic instead
of returning errors since they are required for succesfull boot
anyway.

Bananymous 2fabe1949c BAN: Move RefPtr to its own file and create New.h 
New.h contains definitions for placement new operators and
BAN::allocator and BAN::dealloctor

Bananymous de9f109f2a BAN: Add data() member function to Array 2023-04-03 17:00:52 +03:00
Bananymous e49d3c7bfe BuildSystem: We are now using cmake instead of plain make 
I have been annoyed for a while since I had to build everything
when running the os since the buildsystem was really bad.

I wanted to rewrite the whole build system and changed to using cmake

:)

Bananymous 22e45278a2 Kernel: Fix PC Screen font parsing 
I had misread the format and the parsing code was incorrect. I also
changed fonts to store unicode codepoints as 32 bit integers, so
every character can be represented

Bananymous 392da37f9a BAN: Function storage is now aligned as CallableBase and not max_align_t 
On 32 bit architecture the alignment of 16 bytes did not seem to work
on stack variables. UBSan detected whole lot of misaligned functions
from Ext2.cpp. This patch should make function alignment be big enough?

Bananymous 7458f68c38 BAN: Error can now be constructed from c_string or format string 
If the resulting string would overflow, we just truncate it to fit
the error message buffer (128) bytes
