Lioncash e4c65721fe frontend/ir/type: Generify std::array declaration 
With deduction guides, we can eliminate the need to explicitly size the
array. Also newlines the elements based off their relation, making it
slightly nicer to read.

Lioncash f01dc9192a CMakeLists: Add a namespace to the export 
Avoids potentially dumping boost, fmt, and xbyak targets into a
top-level namespace without any qualification, which can lead to build
errors in projects that already make use of them.

Lioncash 196e7b5e35 frontend/A32/ir_emitter: Mark locals as const where applicable 
Makes const usage consistent within the source file.
 2020-04-22 21:02:46 +01:00
Lioncash 511613c736 frontend/A32/types: Use helper function in operator+ overload 
Allows deduplicating an assert and a cast.
 2020-04-22 21:02:46 +01:00
Lioncash 796bb8a7f7 frontend/A64/types: Make RegNumber() and VecNumber() constexpr 
Given they simply perform casting, they can be safely made constexpr.
 2020-04-22 21:02:46 +01:00
Lioncash 0c43228ad5 frontend/A64/types: Use helper functions in operator+ overloads 
Allows us to get rid of another explicit cast.
 2020-04-22 21:02:46 +01:00
Lioncash a1cace21a9 frontend/ir/ir_emitter: Apply const to locals where applicable 
Makes const usage consistent with all other functions in the source
file.
 2020-04-22 21:02:46 +01:00
Lioncash 0a35836998 frontend/ir/ir_emitter: Use switch constructs in floating point opcodes where applicable 
This'll reduce the amount of noise necessary in changes implementing
half-precision instructions, as the type can just be prepended to the
switch cases, instead of rewriting the whole if/else branch.

Lioncash bac945f2d8 A32: Resolve parameter discrepancies discovered via use of the Imm template 2020-04-22 21:02:46 +01:00
Lioncash 4ba2318b2e A32: Replace immediate type aliases with the Imm template 
Replaces type aliases of raw integral types with the more type-safe Imm
template, like how the AArch64 frontend has been using it.

This makes the two frontends more consistent with one another.
 2020-04-22 21:02:46 +01:00
Lioncash f96036b3f1 A32/barrier: Correct PC assignment within ISB 
The SetRegister() IR function doesn't allow specifying the PC as a
register. This is a discrepancy that slipped through (my bad). Instead,
we can use BranchWritePC(), like how the other similar PC modifying
locations do it.
 2020-04-22 21:02:46 +01:00
Lioncash 8103652a91 frontend: Move imm.h to the top-level directory of the frontends 
Preparation to utilize the immediate type within the A32 backend as
well, which will allow eliminating numerous type aliases like Imm4,
Imm5, etc.
 2020-04-22 21:02:46 +01:00
Lioncash 64e51a6d4d A32/disassembler_arm: Mark utility functions as static where applicable 
These don't depend on class state and can be marked static to make that
explicit.
 2020-04-22 21:02:46 +01:00
Lioncash 8316d231e9 A32: Implement barrier instructions introduced in ARMv7 
Provides basic implementations of the barrier instruction introduced
within ARMv7. Currently these simply mirror the behavior of the AArch64
equivalents.

Lioncash b2f7a0e7ba A32: Implement ARM-mode SDIV/UDIV 
Now that we have Unicorn in place, we can freely implement instructions
introduced in newer versions of the ARM architecture.
 2020-04-22 21:02:46 +01:00
Lioncash c0ae23bbb7 A32/translate_thumb: Clean up formatting 
Performs a similar tidying up of the Thumb translator, like what was
done with the regular ARM translator to make it consistent with the rest
of the codebase.

The A32 backend (both Thumb and ARM), will likely see more changes to it
in the near future, so this just acts as a "dusting off".

Lioncash d12e375481 common/fp/op/FPConvert: Remove unnecessary casts in FPConvert() 
These were made unnecessary in 2c2fdb435cf8e358a0c5b907ce8131e434df3f22,
but were missed during the initial removal.

Lioncash 64e3d233f4 A64: Handle half-precision variants of FP->Fixed-point instructions 2020-04-22 21:01:45 +01:00
Lioncash 4fc531f71b ir/basic_block: Forward declare headers where applicable 
Now that the constructor and destructors have been placed within the cpp
file, we can forward declare the memory pool data structures. Now, a
change to the memory pool code won't ripple across the entirety of the
IR emitter.

Lioncash 427b7afd66 frontend/ir/microinstruction: Add missing fixed-point opcodes to ReadsFromAndWritesToFPSRCumulativeExceptionBits() 2020-04-22 21:01:45 +01:00
Lioncash c9777ef997 common/fp/info: Make half-precision info struct functions return correctly sized types 
While initially done to potentially prevent creating bugs due to C++
having a silly type-promotion mechanism involving types < sizeof(int)
and unsignedness, given that the bulk of these functions' usages
are on exit paths, these can return the correct type to avoid the need
to cast at every usage point.

Lioncash 9309d95b17 ir/block: Default ctor and dtor in the cpp file 
Prevents potentially inlining allocation code everywhere. While we're at
it, also explicitly delete/default the copy/move constructor/assignment
operators to be explicit about them.
