ChunkFile doesn't use any of the file utilities, so we can drop these
headers to avoid pulling in unnecessary dependencies. This also
uncovered a few indirect inclusions.
This only queries internal state, it doesn't modify it. With minor
adjustments to BTEmu, this also allows us to make its usage instance a
constant reference.
The required version of MSVC already supports [[maybe_unused]], so we
can utilize this here. When GCC 7 and clang 3.9 become hard
requirements, we can eliminate this macro entirely and replace it with
[[maybe_unused]].
UNUSED is quite a generic macro name and has potential to clash with
other libraries, so rename it to DOLPHIN_UNUSED to prevent that, as well
as make its naming consistent with the force inline macro
This is much better as prefixed double underscores are reserved for the
implementation when it comes to identifiers. Another reason its better,
is that, on Windows, where __forceinline is a compiler built-in, with
the previous define, header inclusion software that detects unnecessary
includes will erroneously flag usages of Compiler.h as unnecessary
(despite being necessary on other platforms). So we define a macro
that's used by Windows and other platforms to ensure this doesn't
happen.
Instead of globbing things under an ambiguous Common.h header, move
compiler-specifics over to Compiler.h. This gives us a dedicated home
for anything related to compilers that we want to make functional across
all compilers that we support.
This moves us a little closer to eliminating Common.h entirely.
Rather than have a separate independent variable that we need to keep
track of in conjunction with the JIT code buffer size itself, amend the
analyst code to use the code buffer constant in JitBase.
Now if the size ever changes, then the analyst will automatically adjust
to handle it.
Given the code buffer is something truly common to all JIT
implementations, we can centralize it in the base class and avoid
duplicating it all over the place, while still allowing for differently
sized buffers.
Gets rid of an inclusion dependency with the DSP interpreter, as well as
a header-based dependency on the DSP opcode tables. This also uncovered
an indirect inclusion on the logger within DSPSymbols.cpp
As peculiar as this may be, decrementer exceptions by means of setting
the decrementer's zeroth bit from 0 to 1 is valid behavior by software
(and is defined in Programming Environments for 32-bit Microprocessors
in section 2.3.14.1 -- Decrementer operation). Given it's valid behavior,
it doesn't necessarily make sense to use a panic alert and halt, as this
isn't a condition where everything should be considered in a critical
state.
Instead, change it to an info log, so we still make note of it, but
without potentially tearing down state or halting emulation.
