Note: for Windows users, please go to nall/intrinsics.hpp line 60 and
correct the typo from "DISPLAY_WINDOW" to "DISPLAY_WINDOWS" before
compiling, otherwise things won't work at all.
This will be a really major WIP for the core SNES emulation, so please
test as thoroughly as possible.
I rewrote the 65816 CPU core's dispatcher from a jump table to a switch
table. This was so that I could pass class variables as parameters to
opcodes without crazy theatrics.
With that, I killed the regs.r[N] stuff, the flag_t operator|=, &=, ^=
stuff, and all of the template versions of opcodes.
I also removed some stupid pointless flag tests in xcn and pflag that
would always be true.
I sure hope that AWJ is happy with this; because this change was so that
my flag assignments and branch tests won't need to build regs.P into
a full 8-bit variable anymore.
It does of course incur a slight performance hit when you pass in
variables by-value to functions, but it should help with binary size
(and thus cache) by reducing a lot of extra functions. (I know I could
have used template parameters for some things even with a switch table,
but chose not to for the aforementioned reasons.)
Overall, it's about a ~1% speedup from the previous build. The CPU core
instructions were never a bottleneck, but I did want to fix the P flag
building stuff because that really was a dumb mistake v_v'

Changelog:
- target-ethos/ is now target-higan/ (will unfortunately screw up diffs
pretty badly at this point.)
- had a serious bug in nall::optional<T>::operator=, which is now fixed.
- added tracer (no masking just yet, I need to write a nall::bitvector
class because I don't want to hard-code those anymore.)
- added usage logging (keep track of RWX/EP states for all bus
addresses.)
- added read/write to poke at memory (hex also works for reading, but
this one can poke at MMIO regs and is for one address only.)
- added both run.for (# of instructions) and run.to (program counter
address.)
- added read/write/execute breakpoints with counters for a given
address, and with an optional compare byte (for read/write modes.)
About the only major things left now for loki is support for trace
masking, memory export, and VRAM/OAM/CGRAM access.
For phoenix/Console, I really need to add a history to up+down arrows,
and I should support left/right insert-at.

Changelog:
- added Cocoa target: higan can now be compiled for OS X Lion
[Cydrak, byuu]
- SNES/accuracy profile hires color blending improvements - fixes
Marvelous text [AWJ]
- fixed a slight bug in SNES/SA-1 VBR support caused by a typo
- added support for multi-pass shaders that can load external textures
(requires OpenGL 3.2+)
- added game library path (used by ananke->Import Game) to
Settings->Advanced
- system profiles, shaders and cheats database can be stored in "all
users" shared folders now (eg /usr/share on Linux)
- all configuration files are in BML format now, instead of XML (much
easier to read and edit this way)
- main window supports drag-and-drop of game folders (but not game files
/ ZIP archives)
- audio buffer clears when entering a modal loop on Windows (prevents
audio repetition with DirectSound driver)
- a substantial amount of code clean-up (probably the biggest
refactoring to date)
One highly desired target for this release was to default to the optimal
drivers instead of the safest drivers, but because AMD drivers don't
seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD
has too big a market share. Hopefully with v093 officially released, we
can get some public input on what AMD doesn't like.
