Lioncash 8620de6b20 common/bit_util: Replace CLZ/CTZ operations with standardized ones
Makes for less code that we need to maintain.

ReinUsesLisp b3587102d1 core/memory: Read and write page table atomically
Squash attributes into the pointer's integer, making them an uintptr_t
pair containing 2 bits at the bottom and then the pointer. These bits
are currently unused thanks to alignment requirements.

Configure Dynarmic to mask out these bits on pointer reads.

While we are at it, remove some unused attributes carried over from
Citra.

Read/Write and other hot functions use a two step unpacking process that
is less readable to stop MSVC from emitting an extra AND instruction in
the hot path:

 mov         rdi,rcx
 shr         rdx,0Ch
 mov         r8,qword ptr [rax+8]
 mov         rax,qword ptr [r8+rdx*8]
 mov         rdx,rax
-and         al,3
 and         rdx,0FFFFFFFFFFFFFFFCh
 je          Core::Memory::Memory::Impl::Read<unsigned char>
 mov         rax,qword ptr [vaddr]
 movzx       eax,byte ptr [rdx+rax]

Lioncash be1954e04c core: Fix clang build
Recent changes to the build system that made more warnings be flagged as
errors caused building via clang to break.

Fixes #4795

Lioncash 87c64c41d2 system_control: Make functions internally linked where applicable
These functions are only ever used internally as implementation details
for GenerateRandomRange(), so these can be given internal linkage.

Merge pull request #4327 from lioncash/desig2
address_space_info: Make use of designated initializers
2020-07-16 17:41:55 -03:00
Lioncash f2f876e3ff memory_layout: Remove unused data member
This isn't used, so it can be removed entirely, shrinking the structure
size by 8 bytes.

Lioncash ed0fe04b4f address_space_info: Use type alias to simplify code
We can define an alias for the index arrays and then just reuse it to
make the code nicer to read.
2020-07-13 10:42:52 -04:00
Lioncash c3eb42de65 address_space_info: Make use of designated initializers
We can alter the structure so that we can use designated initializers in
the array, eliminating the comments that indicate their field names.

Lioncash 4620580245 kernel/memory: Remove #pragma once within cpp file
This isn't necessary in a cpp file and will cause warnings on clang.

Lioncash 1ecaa86a52 kernel/memory: Remove unused includes
Prevents header churn and needing to recompile these files if these
headers are ever changed in the future.

Prevents unused variable warnings.

Lioncash 26aee55aef kernel/memory: Make use of std::array consistently in address_space_info
This allows tuning standard library implementations to enable or disable
range checks at runtime, which is nicer for debugging.

Lioncash dfa582169b kernel/memory: Resolve -Wshadow warnings
Prevents variable name clashing.

Lioncash 93c083aef1 kernel/memory: Amend potential encoding warnings
While èis generally representable in some language encodings, in some
it isn't and will result in compilation warnings occurring. To remain
friendly with other language's codepages on Windows, we normalize it to
an ASCII e.

Lioncash f77b5dfe81 page_table: Remove unused captures
Any time the lambda function is called, the permission being used in the
capture would be passed in as an argument to the lambda, so the capture
is unnecessary.

Lioncash 7e585bce28 memory/slab_heap: Make use of static_cast over reinterpret_cast

can just make use of that instead.
