This one verifies bitmasks where low bits are set to 1 (hence the name).
Any stray 0 among the lower ones or any stray 1 among the higher zeros
renders the mask invalid.
The edge cases of all zeros and all ones are considered valid masks.
It uses an efficient implementation. It's the counterpart of

- Moves all test code from DSPTool into UnitTests/Core/DSPAssemblyTest.
- Converts test files (which could only be loaded if they were in the
shell's working directory, so basically never) into C++ values.
- Enables most of the commented-out tests.
- Removes non-deterministic random code test.
The current prefixing makes it harder to build test executables directly
from the command line, since the target name breaks CMake convention and
doesn't match the name passed to `add_dolphin_test`. They all have "Test"
somewhere in the name anyways.
This adds unit tests for IOS/ESFormats, and in particular, for the
TMDReader. It is tested using invalid TMDs (to check IsValid()) and
two valid, properly signed TMDs.
Things which are now tested:
* Title type helper functions.
* TMDReader: Validity check.
* TMDReader: General information returned by the Get*() methods.
* TMDReader: Raw TMD and generated TMD view, compared against IOS.
* TMDReader: Game ID generation code (which is Dolphin specific).
* TMDReader: Content information: getting by ID/index, order, metadata.

This moves all the byte swapping utilities into a header named Swap.h.
A dedicated header is much more preferable here due to the size of the
code itself. In general usage throughout the codebase, CommonFuncs.h was
generally only included for these functions anyway. These being in their
own header avoids dumping the lesser used utilities into scope. As well
as providing a localized area for more utilities related to byte
swapping in the future (should they be needed). This also makes it nicer
to identify which files depend on the byte swapping utilities in
particular.
Since this is a completely new header, moving the code uncovered a few
indirect includes, as well as making some other inclusions unnecessary.
This attempts to make some bit arithmetic more self-documenting and also
make it easier during review to identify potential off-by-one errors by
making it possible to just specify which bits are being extracted.
Functions both support the case where bits being extracted can vary and
fixed bit extraction. In the case the bits are fixed, compile-time asserts
are present to prevent accidental API usage at compile-time.
e.g. Instead of shifting and masking to get bits 10 to 15,
Common::ExtractBits<10, 15>(value) can just be done instead.
Jan 04 22:55:01 <leoetlino> fwiw, it looks like there are new warnings in the RegCache code
Jan 04 22:55:04 <leoetlino> Source/Core/Core/PowerPC/Jit64/FPURegCache.cpp:13:33: warning: declaration shadows a variable in the global namespace [-Wshadow]
Jan 04 22:56:19 <@Lioncash> yeah, the jit global should have a g_ prefix.
This fixes shadowing warnings and adds the g_ prefix to a global.
The min-heap provides no ordering when the key is the same on 2
nodes. Disambiguate identical times by tracking the order items
were added into the queue.
MSVC's implementation of numeric_limits currently generates incorrect
signaling NaNs. The resulting values are actually quiet NaNs instead.
This commit is based off of a solution by shuffle2. The only
difference is a template specialization for floats is also added
to cover all bases
Approximately three or four times now, the issue of pointers being
in an inconsistent state been an issue in the video backend renderers
with regards to tripping up other developers.
Global (ugh) resources are put into a unique_ptr and will always have a
well-defined state of being - null or not null
They are used to remove the flush amounts, but as we don't
flush anymore on vertex loader changes (only on native
vertex format right now), this optimization is now unneeded.
This will allow us to hard code the frac factors within the
vertex loaders.
CMake 3.0 prints out a warning when adding any target whose name contains
a slash. This commit fixes the warnings by using an underscore instead.
Run 'cmake --help-policy CMP0037' for more details.
videoBuffer -> s_video_buffer
size -> s_video_buffer_write_ptr
g_pVideoData -> g_video_buffer_read_ptr (impl moved to Fifo.cpp)
This eradicates the wonderful use of 'size' as a global name, and makes
it clear that s_video_buffer_write_ptr and g_video_buffer_read_ptr are
the two ends of the FIFO buffer s_video_buffer.
Oh, and remove a useless namespace {}.
This was actually never used as far as I can tell. There was no wx event handling done whatsoever for the global ID, So this is basically a dead function.
A previous PR changed a whole lot of min/maxes to std::min/std::max
but made a mistake here and used a templated min which cast it's
arguments to unsigned instead of casting return value.
This resulted in glitchy artifacts in bright areas (See issue 7439)
I rewrote the code to use a proper clamping function so it's cleaner
to read.
These directories have been unused for several years and without any automated
way of running the tests, they are pretty much useless.
While they might be useful as a reference, in their present state they should
not be kept in the repository.
The "dsptool" executable is not included in the bundle.
The "tester" executable is not included in the bundle and it no longer
installed on other platforms, since it is neither expected nor useful
to install unit tests.
Also, don't check to see if a directory is a wad file. They aren't. This removes an annoying and invalid debug assertion with the debug build.

and use wxGetKeyState on platforms other than Windows.
I am not sure if wxGetKeyState is unreliable on Windows or if
the use of GetAsyncKeyState() is simply historical, but for now
I've left the Windows call in there just in case.
This does mean that Host_GetKeyState() is currently only valid
for the small set of keycodes that overlap between wx and Win32,
one of which is VK_TAB/WXK_TAB.
Anyway, please test wxGetKeyState on Windows and remove the
ifdef if it works, so we can extend it to the remaining hotkeys.
