Ninja puts way more effort into compiling targets in parallel, and
ignores dependenceis until link time.
So we need to jump though hoops to force ninja to compile
pch.cpp before any targets which depend on the PCH.
I have no idea why cmake supports PUBLIC on target_sources,
but it does. It causes all targets that depend on this target
to try and include the files in their sources.
Except it doesn't take paths into account, so it breaks. Mabye
it would work if you used an abolute source? But I'm not sure
there is a sane usecase.
These messages hid other, more important, ones often. I have left AttemptMaxTimesWithExponentialDelay and GetSysDirectory/SetSysDirectory as info, since those are called infrequently and can be useful to the end-user.

A description of what was going wrong:
JitArm64::Init first calls CodeBlock::AllocCodeSpace, after which
CodeBlock and Arm64Emitter consider us to have 96 MB of code space
available. JitArm64::Init then calls AddChildCodeSpace, which is
supposed to take 64 MiB of that space and give it to m_far_code.
CodeBlock's view of how much space there is gets updated from 96 MiB
to 32 MiB, but due to the missing call, Arm64Emitter keeps thinking
that it has 96 MiB of space available.
The last thing JitArm64::Init does is to call ResetFreeMemoryRanges.
This function asks Arm64Emitter how much code space is available and
stores a range of that size in m_free_ranges_near, meaning that
m_free_ranges_near ends up being backed by both nearcode and farcode!
This is a ticking time bomb; as soon as we grab memory from
m_free_ranges_near which is backed by farcode, we're in trouble.
The crash I ran into in my testing was caused by fastmem code being
allocated in farcode (our backpatch handler only handles accesses made
from nearcode), but you may as well get errors caused by code intended
for nearcode overwriting code intended for farcode or vice versa.
So why did NBA Live 2005 crash when most games had no problems,
and why was the bug bisected to the commit that increased the size
of far code from 16 MiB to 64 MiB? Well, as long as we're only
using the first 32 MiB of the big 96 MiB range, everything works.
What happens with NBA Live 2005 (I have not investigated exactly
through what mechanism this happens) is that at some point the range
in m_free_ranges_near gets split into two ranges, one which is
backed by nearcode and one which is backed by farcode. Dolphin
prefers to select the biggest range available (we don't want to
pick a tiny 1 KiB range that may not be able to fit the whole block
we're about to emit, after all), and after increasing the size of
farcode to 64 MiB, farcode is bigger than nearcode.
Fixes a crash that could occur if the static constructor function for
the MainSettings.cpp TU happened to run before the variables in
Common/Version.cpp are initialised. (This is known as the static
initialisation order fiasco.)
By using wrapper functions, those variables are now guaranteed to be
constructed on first use.
Using unsigned char* or signed char* results in a deprecation warning, which is treated as an error. It needs to be casted to regular char* for it to work.
This format string is by definition dynamic and can't be checked at compile time. There are other similar strings in the log handler and in asserts, but they use vformat and thus don't need fmt::runtime. We might be able to do a similar thing where the untranslated string is compile-time checked, but FmtFormatT is used in so few places that I don't want to handle that in this PR.
HRWrap now allows HRESULT to be formatted, giving useful information beyond "it failed" or a hex code that isn't obvious to most users. This commit does not add any uses of it, though.
Now, enums are properly displayed, and BitFieldArray is also displayed nicely. Signed values also work correctly, and 1-bit fields are not treated as bools unless the bitfield is explicitly marked as a bool.
PNG_FORMAT_RGB and PNG_COLOR_TYPE_RGB both evaluate to 2, but PNG_FORMAT_RGBA evaluates to 3 while PNG_COLOR_TYPE_RGBA evaluates to 6; the bit indicating a palette is 1 while the bit indicating alpha is 4.
This does this following things:
- Default to the runtime automatic number of threads for pre-compiling shaders
- Adds a distinct automatic thread count computation for pre-compilation (which has less other things going on
and should scale better beyond 4 cores)
- Removes the unused logical_core_count field from the CPU detection
- Changes the semantics of num_cores from maximaum addressable number of cores to actually available CPU cores
(which is also how it was actually used)
- Updates the computation of the HTT flag now that AMD no longer lies about it for its Zen processors
- Background shader compilation is *not* enabled by default
This moves the only direct call to zlib’s crc32() into its own
translation unit, but that operation is cold enough that this won’t
matter in the slightest. crc32_z() would be more appropriate, but
Android has an older zlib version…
This replaces the MAX_LOGLEVEL define with a constexpr variable
in order to fix self-comparison warnings in the logging macros
when compiling with Clang. (Without this change, the log level check
in the logging macros is expanded into something like this:
`if (LINFO <= LINFO)`, which triggers a tautological compare warning.)
PR #10066 added functionality to call std::abort when a panic alert occurs; however, that PR only implemented it for MsgAlert and not MsgAlertFmtImpl, meaning that the functionality was not used with PanicAlertFmt (only PanicAlert, which is not used frequently).
When RenderDoc is attached, wglShareLists fails for some reason (see baldurk/renderdoc#2361). wglCreateContextAttribsARB has a parameter for the share context, so there's no reason to use a separate wglShareLists call.

Prompted by https://dolphin.ci/#/builders/24/builds/985
A 1-character typo in a recent PR caused FifoCI builds to break
horribly and spew millions of panic alerts until buildbot crashed.
This PR adds a new config option -- defaulting to off -- that allows
Dolphin to abort early on when a panic alert occurs instead of
continuing forever.
Manually encoding and decoding logical immediates is error-prone.
Using ORRI2R and friends lets us avoid doing the work manually,
but in exchange, there is a runtime performance penalty. It's
probably rather small, but still, it would be nice if we could
let the compiler do the work at compile-time. And that's exactly
what this commit does, so now I have no excuse for trying to
manually write logical immediates anymore.
Public domain does not have an internationally agreed upon definition,
As such it's generally preferred to use an extremely liberal license,
which can explicitly list the rights granted by the copyright holder.
The CC0 license is the usual choice here.
This "relicensing" is done without hunting down copyright holders, since
it is presumed that their release of this work into the public domain
authorizes us to redistribute this code under any other license of our
choosing.
This code was part of Dolphin's relicensing from v2 to v2+ a while back,
we just never updated these copyright headers. I double-checked that
segher gave us permission to relicense this code to v2+ on 2015-05-16.

Without this, the code added in ac28b89 misbehaves and considers
AArch64 netplay clients to not have hardware FMA support, telling
all clients to disable FMA support, which causes a desync between
x64 and AArch64 due to JitArm64 not being able to disable FMA support.
