This is a higher level, more concise wrapper for bitsets which supports
efficiently counting and iterating over set bits. It's similar to
std::bitset, but the latter does not support efficient iteration (and at
least in libc++, the count algorithm is subpar, not that it really
matters). The converted uses include both bitsets and, notably,
considerably less efficient regular arrays (for in/out registers in
PPCAnalyst).
Unfortunately, this may slightly pessimize unoptimized builds.
GCC has optimized this using the exact same code since 4.7 or 4.8.
Android building falls back to the __linux__ route.
No need to keep these around anymore since we aren't building on an old GCC version.
This extends the register cache's BindToRegister function with a doLoad argument just like x86's.
The speedup is minor for these implemented integer instructions.
We weren't setting the backbuffer dimensions on this platform when the window is created.
This required a resize event to first be fired in order to see anything.
So instead do like GLX + X11 platforms do and query the dimensions and set the backbuffer to them.
Should fix issue 7666.
This is good hygiene, and also happens to be required to build Dolphin
using Clang modules.
(Under this setup, each header file becomes a module, and each #include
is automatically translated to a module import. Recursive includes
still leak through (by default), but modules are compiled independently,
and can't depend on defines or types having previously been set up. The
main reason to retrofit it onto Dolphin is compilation performance - no
more textual includes whatsoever, rather than putting a few blessed
common headers into a PCH. Unfortunately, I found multiple Clang bugs
while trying to build Dolphin this way, so it's not ready yet, but I can
start with this prerequisite.)
I found it via clang complaining about a useless null check on an array,
but I decided to get rid of the array in favor of dynamic allocation, as
there was no reason to assume a maximum length of 0x32 bytes. Plus, add
a CFString type check just in case, and switch to UTF-8 in the
off-chance it matters.
The result has not actually been tested, as I have no CD drive.
