asynts 90536a1558 AK: Consider long and unsigned long as integral types.
Two things I hate about C++:

 1. 'int', 'signed int' and 'unsigned int' are two distinct types while
    'char, 'signed char' and 'unsigned char' are *three* distinct types.

    This is because 'signed int' is an alias for 'int' but 'signed char'
    can't be an alias for 'char' because on some weird systems 'char' is
    unsigned.

    One might think why not do it the other way around, make 'int' an
    alias for 'signed int' and 'char' an alias for whatever that is on
    the platform, or make 'char' signed on all platforms. But who am I
    to ask?

 2. 'unsigned long' and 'unsigned long long' are always different types,
    even if both are 64 bit numbers.

This commit fixes a few bugs that coming from this.

AnotherTest 72edb33670 AK: Generalise 'PrintfImplementation'
This makes PrintfImplementation usable with any sequence, provided that
a 'next element' function can be written for it.
Does not affect the behaviour of printf() and co.

asynts 1b3169f405 AK: Define MakeUnsigned and MakeSigned for char.
For some weird reason the C++ standard considers char, signed char and
unsigned char *three* different types. On the other hand int is just an
alias for signed int, meaning that int, signed int and unsigned int are
just *two* different types.

Ben Wiederhake 53abc626c2 AK: Print RHS and LHS in EXPECT_EQ if we can
This makes error messages more useful during debugging.

min(a, b) now returns a if both are equivalent.
max(a, b) now returns a if both are equivalent.

Andreas Kling ce2c5b375c AK: Add global is<T>() and downcast<T>()
Let's unify the is<T>/to<T> implementations that currently exist in
separate versions in LibCore and LibWeb.

Andreas Kling 70cb4491d7 AK: Use "signed char" as the opposite of "unsigned char"
I totally forgot about the C++ basics here. There are three distinct
types: "char", "signed char" and "unsigned char". Whether "char" is
signed or unsigned is implementation specific.

Andreas Kling 900f51ccd0 AK: Move memory stuff (fast memcpy, etc) to a separate header
Move the "fast memcpy" stuff out of StdLibExtras.h and into Memory.h.
This will break a ton of things that were relying on StdLibExtras.h
to include a bunch of other headers. Fix will follow immediately after.

This makes it possible to include StdLibExtras.h from Types.h, which is
the main point of this exercise.

This function can be used to more cleanly write the common operation of
clamping a value between two values.

Andreas Kling 94ca55cefd Meta: Add license header to source files
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.

For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.

Going forward, all new source files should include a license header.

Andreas Kling 57c29491a3 Kernel+AK: Remove AK/StdLibExtras.cpp, moving kernel stuff to Kernel/.
We had some kernel-specific gizmos in AK that should really just be in the
Kernel subdirectory instead. The only thing remaining after moving those
was mmx_memcpy() which I moved to the ARCH(i386)-specific section of
LibC/string.cpp.

Andreas Kling 27f699ef0c AK: Rename the common integer typedefs to make it obvious what they are.
These types can be picked up by including <AK/Types.h>:

* i8, i16, i32, i64 (signed)

Robin Burchell 0dc9af5f7e Add clang-format file
Also run it across the whole tree to get everything using the One True Style.
We don't yet run this in an automated fashion as it's a little slow, but
there is a snippet to do so in makeall.sh.

Andreas Kling cec16105cc Make sure all GraphicsBitmap scanlines are 16-byte aligned.
This is a prerequisite for some optimizations.

Andreas Kling 6693cfb26a Kernel: Don't use MMX memcpy() in the kernel.
I just discovered the hard way that clobbering FPU/MMX/SSE registers in the
kernel makes things very confusing for userspace (and other kernel threads.)

Let's banish all of those things from the kernel to keep things simple.

Andreas Kling 301a269ca0 Get rid of SERENITY macro since the compiler already defines __serenity__

Andreas Kling 47d270b577 WindowServer: Factor out window frame logic into a WSWindowFrame class.
The window frame is an object that contains a window, its title bar and
window border. This way WSWindowManager doesn't have to know about all the
different types of window borders, titlebar rects, etc.

Andreas Kling 809ffa56d7 Kernel: Reduce code duplication in exception handlers. 2019-02-20 12:28:41 +01:00
Andreas Kling 022f7790db Use modern C++ attributes instead of __attribute__ voodoo.
This is quite nice, although I wish [[gnu::always_inline]] implied inline.
Also "gnu::" is kind of a wart, but whatcha gonna do.

Andreas Kling 1f159eaab0 Add a fast memcpy() using MMX when we're moving >= 1KB.
This is a nice speedup for WindowServer. I'll eventually have to do this
with SSE but the kernel doesn't support SSE yet so this is it for now.
