Michel Heily 97fac000b0 Optimize memory accesses by inlining
The previous approach yielded a vtable call to the Bus vtable.
This approach inlines the memory mapping

Michel Heily fb93ebb4ed feat/arm7tdmi_dispatch_table: Done!
Moved away from using lazy_static for this one since every access to a
lazy_static reference adds a runtime check, Currently using a build.rs script to generate a const table instead.

Worked out the ARM decoding issues, seems to run fine now.

Though the dynamic decoding for ARM is broken now since I had to change things in Data Processing and MSR instructions

TODO use `const fn` when it becomes stable

Michel Heily a523a37d32 [WIP] Start working on arm7tdmi dispatch table.
Lookup tables are generally faster than matching in most architectures.
There is some trouble in decoding some arm data processing instructions
so this is non-default feature for now

* Crashes on armwrestler but many games seem to work

Michel Heily 8f11bebd2b fix/performance/accuracy: Reimplement sysbus stall cycle counting.
Previously I did not account for gamepak 32-bit accesses being two 16bit (NSEQ+SEQ or SEQ+SEQ) accesses,
This resulted in less cycles being accounted for, resulting in more wasted CPU cycles per frame and was a huge performance hit.

I re-implemented this with look-up-tables also to speed up the cycle
count routing `SysBus::get_cycles` and also account for 32bit gamepak memory access.

Michel Heily c4c8163b0e optimize/timers: Get rid of the while loop in Timer::update.
Profiling with 'perf' I discovered that too much time was spent inside
Timer::update when the prescalar was 0 (frequency of 1 cycle).
This was due to the while loop I used. I optimized this loop out and
there is an appearent performance increase.

Michel Heily f0aa671674 optimize/cpu: Pass Arm/Thumb Instruction and other large structs as references.
Also, get rid of unnecessary derive Copy.

Since the ArmInstruction (and Thumb) derived from Copy, the compiler
always saves them to the stack when they are passed by value to other
functions, thus making some unwanted performance overhead.

I removed the derive Copy, and also pass them as references. This
project has a lot of "derive Copy" everywhere, and I should take note if
this is happenning elsewhere aswell.

Michel Heily c68b9502fe bugfix: Fix bad write impl of DISPSTAT again.
I should really pay more attention to the docs..
The previous fix (bb843ea5) was not enough as it caused vblank,hblank
and vcount-match flags to be overwritten when they really should have
just been ignored.

This caused Dragon Ball - Advance Adevnture to fail booting

Michel Heily c96fa38a2d bugfix: Fix improper write to DISPSTAT register
For some reason, probably typing mistkae, I `or`ed the value being written to DISPSTAT,
causing bits to never actually turn off, affectivly making HBLANK/VBLANK
interrupts linger forever.

This probably has caused some nasty glitches that I don't even know of, but two confirm issues solved
by this are Mariokart and Pacman.

This commit fixes #14 and #13
