Decreases total Wii state save time (not counting compression) from
~570ms to ~18ms.
The compiler can't remove this check because of potential aliasing; this
might be fixable (e.g. by making mode const), but there is no reason to
have the code work in such a braindead way in the first place.
- DoVoid now uses memcpy.
- DoArray now uses DoVoid on the whole rather than Doing each element
(would fail for an array of STL structures, but we don't have any of
those).
- Do also now uses DoVoid. (In the previous version, it replicated
DoVoid's code in order to ensure each type gets its own implementation,
which for small types then becomes a simple load/store in any modern
compiler. Now DoVoid is __forceinline, which addresses that issue and
shouldn't make a big difference otherwise - perhaps a few extra copies
of the code inlined into DoArray or whatever.)
(1) Rename ABI_ALL_CALLEE_SAVED to ABI_ALL_CALLER_SAVED, because that's
what it was actually defined as (and used as). Derp.
(2) RegistersInUse is always used for the purpose of saving registers
before calling a C++ function in the middle of a JIT block (without
flushing). There is no need to save callee-saved registers in this
case. Change the name to CallerSavedRegistersInUse and mask with
ABI_ALL_CALLER_SAVED.
Nothing obvious broke when starting up a Melee game. (I added a test
for anything actually being masked out; it happens, but in this
particular case seemed to occur at most a few dozen times per second, so
the actual performance benefit is probably negligible.)
This class loads all the common PP shader configuration options and passes those options through to a inherited class that OpenGL or D3D will have.
Makes it so all the common code for PP shaders is in VideoCommon instead of duplicating the code across each backend.
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.
This moves the Gekko disassembler to Common where it should be. Having it in the Bochs disassembly Externals is incorrect.
Unlike the PowerPC disassembler prior however, this one is updated to have an API that is more fitting for C++. e.g. Not needing to specify a string buffer and size. It does all of this under the hood.
This modifies all the DebuggingInterfaces as necessary to handle this.
On error mmap returns MAP_FAILED(-1) not null.
FreeBSD was checking the return correctly, Linux was not.
This was noticed by triad attempting to run Dolphin under valgrind and not getting a memory space under the 2GB limit(Because -1 wraps around on
unsigned obviously)
Previously using the new "lower 8 bits" registers (SIL, SPL, ...) caused SETcc
to write to other registers (for example, SETcc SIL would generate SETcc DH).
It was only used for Windows XP and lower.
This also bumps the _WIN32_WINNT define in the stdafx precompiled headers to set the minimum version as Windows Vista.
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.
This shouldn't really be exposed as a public function and should only be called through other Do class functions that take a container type as a parameter.
Sometimes (in particular when using non-typesafe functions) it can be convenient to have a getter method rather than performing a potentially lengthy explicit cast.
This allows for removal of the strcpy calls, also it's technically way more safe, though I doubt we'll ever have a log name larger than 128 characters or a short description larger than 32 characters.
Also moved these assignments into the constructor's initializer list.
If a CPU string was incapable of being found we would return a null pointer, which would crash with strncpy.
Also if we couldn't get a CPU implementer we would call free() to a null pointer.
In addition, detect 64bit ARM running.
MemoryUtil.cpp was incorrectly using the old __x86_64__ define when it should be using _M_X86_64.
It was also using _ARCH_64 when it shouldn't have which was causing an errant PanicAlert to come up in my development.
Some compilers we care about (mostly g++) do not support std::make_unique yet,
but we still want to use it in our codebase to make unique_ptr code more
readable. This commit introduces an implementation derivated from the libc++
code in the Dolphin codebase so we can use it right now everywhere.
Adapted from delroth's pull request.
Set the x87 precision, even on x64. Since we are using x87 instructions
in the JIT now, we can't guarantee that x87 precision will never
influence Dolphin on x64.
The new NOP emitter breaks when called with a negative count. As it
turns out, it did happen when deoptimizing 8 bit MOVs because they are
only 4 bytes long and need no BSWAP.
Fixes issue 6990.
This uses a bit of templating to remove the duplicate code that is the CodeBlocks in each emitter headers.
No actual functionality change in this.
When creating a Fixupbranch we were swapping the BL and B targets.
I think this was found by PPSSPP a while ago, but they never send PRs to merge their changes upstream.
Between C++11 and C++14, volatile types stopped being trivially
copyable. The serializer has no reason to care about this distinction,
so tack on remove_volatile.
The underlying storage type of a bitfield can be any intrinsic integer type,
but also any enumeration.
Custom storage types are supported if the following things are defined on the storage type:
- casting 0 to the storage type
- bit shift operators (in both directions)
- bitwise & operator
- bitwise ~ operator
- std::make_unsigned specialization
Previously he function was misbehaving because of a missing check for
whether an 8-bit operand was a register operand; it would therefore
emit unnecessary REX prefixes, incorrectly assert on 32-bit targets, and
could potentially emit wrong code in rare cases (like a memory to register
operation involving AH.)
Also, some cleanup while I was in the area to make the function easier to
read.
The workaround of using fixed underlying types produces lots of warnings
in GCC because now the bit-fields are too small for the value range used
for conversion semantics.
Breakpoints have one, but memchecks don't, despite being cleared directly in the breakpoint window.
Now DolphinWX should call the interface functions and not the direct functions of the breakpoints or memchecks for clearing.
Our defines were never clear between what meant 64bit or x86_64
This makes a clear cut between bitness and architecture.
This commit also has the side effect of bringing up aarch64 compiling support.
