Morph 23413c0d44 general: Fix various spelling errors 2021-01-02 10:23:41 -05:00
ReinUsesLisp 8bfa4d6dbf 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 9e72b1df7d 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.

address_space_info: Make use of designated initializers
 2020-07-16 17:41:55 -03:00
Lioncash ed658d92dc memory_layout: Remove unused data member 
This isn't used, so it can be removed entirely, shrinking the structure
size by 8 bytes.
 2020-07-13 10:51:23 -04:00
Lioncash 14332845af 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 c8b9f7bd14 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.

kernel/memory: Resolve several compiler warnings
 2020-05-05 15:41:18 -04:00
Lioncash 12b81f2581 kernel/memory: Remove #pragma once within cpp file 
This isn't necessary in a cpp file and will cause warnings on clang.
 2020-05-03 13:42:07 -04:00
Lioncash 0bf0d27552 kernel/memory: Remove unused includes

headers are ever changed in the future.

 2020-05-03 13:36:20 -04:00
Lioncash 42d43335c9 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 e09098b981 kernel/memory: Resolve -Wshadow warnings 
Prevents variable name clashing.

Lioncash a93929b23a 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 a881161d3c 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 ac3ff8c9ba memory/slab_heap: Make use of static_cast over reinterpret_cast 
Casting from void* with static_cast is permitted by the standard, so we
can just make use of that instead.
