Lioncash 97277c598b A32: Rename vfp2-related files to vfp
Now that we fuzz against Unicorn, we aren't just restricted to VFPv2.
VFPv3 and VFPv4 facilities can now be implemented. This renames
constructs mentioning VFPv2 to just refer to VFP.

Lioncash 8c3122ff46 A64/translate/impl/impl: Mark locals const where applicable in DecodeBitMasks()

Lioncash 966e04d03d A32: Allow hooking of hint instructions in ARM mode.
Mirrors the hooking functionality from the AArch64 frontend to make the
behavior of both consistent.

Lioncash 134b586c5c frontend/ir/ir_emitter: Amend arguments to conversion opcodes
Accidentally caused within 967d1fcc8d6f60749a162a96b997439450fed687.
That one's on me. My bad.

Lioncash e37689315d A32: Implement ARM-mode CRC32 instructions
Implements the ARM-mode variants of the CRC32 instructions introduced
within ARMv8. This is also one of the instruction cases where there is
UNPREDICTABLE behavior that is constrained (we must do one of the
options indicated by the reference manual).

In both documented cases of constrained unpredictable behavior, we treat
the instructions as unpredictable in order to allow library users to
hook the unpredictable exception to provide the intended behavior they
desire.

A32: Replace immediate type aliases with the Imm template
2020-04-22 21:02:46 +01:00
Lioncash 95d9baea67 {A32, A64}/types: Use std::array deduction guides where applicable
We also make the arrays static here, as MSVC tends to load the whole
array every time the function is called, instead of storing the data
within rodata.

This also line breaks the elements a little earlier for readability.

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 c098ade2e7 dynarmic_tests: Resolve CPSR discrepancies in tests
Unicorn internally checks if the LSB is set in order to determine
whether or not it should assume thumb mode internally. Clearing this
ourselves will always result in the incorrect PSR between runs.

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.

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.

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 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.
