Lioncash b5bf890584 load_store_*: Make bracing consistent and variables const where applicable 
Makes bracing consistent, and variables const where applicable to be
consistent with the rest of the codebase.

In most bracing cases, they'd need to be added to conditionals that
would involve checking stack pointer alignment in the future anyways.

Lioncash 7bb5440507 general: Mark hash functions as noexcept 
Generally hash functions shouldn't throw exceptions. It's also a
requirement for the standard library-provided hash functions to not
throw exceptions.

An exception to this rule is made for user-defined specializations,
however we can just be consistent with the standard library on this to
allow it to play nicer with it.

While we're at it, we can also make the std::less specializations
noexcpet as well, since they also can't throw.

Lioncash 3b46b4a37d A64: Implement SQRDMULH's scalar vector variant 
Implements the scalar variant in terms of the vector variant for the
time being.
 2020-04-22 21:01:43 +01:00
Lioncash fe95575b95 general: Replace unreachable-imitating assertions with UNREACHABLE() 
We can just use the self-documenting assertion for indicating
unreachable paths, instead of manually passing false and providing a
message.

Lioncash 64de80839e A64/impl: Reorganize peculiar void use in V_scalar 
To a reader this might look particularly strange, given the function
itself has a void return value, but this is actually valid, given the
function in the return statement also has a void return value.

This instead alters it to be a little easier to parse and potentially be
a little less confusing at a glance.

Lioncash cfd7513a7d ir_opt/verification_pass: Mark locals as const where applicable 
Makes our immutable state a little more explicit.
 2020-04-22 21:01:40 +01:00
Lioncash 8309d49588 A64: Handle reserved instruction cases more specifically where applicable 
These are cases that are defined as reserved within the ARMv8 reference
manual, so we can handle them as such instead of as unallocated
encodings.

While this doesn't actually change emulated behavior, it does at least
allow the JIT to generate the more appropriate exception.

Lioncash 6c2c68bce6 A64: Implement FCMLA's indexed element variant 
With this, all of the instructions introduced with ARMv8.3-CompNum have
an implementation.

Lioncash 7bc7042104 simd_scalar_shift_by_immediate: Change UnallocatedEncoding() path in SaturatingShiftLeft to ReservedValue() 
Strictly speaking, immh being zero is defined as reserved in the ARMv8
reference manual. This was just an error on my part when introducing the
SQSHL immediate scalar variant.

Lioncash dc97977576 ir_opt/a32_get_set_elimination_pass: Mark local variables as const where applicable 
Makes our intended immutable state slightly more explicit.

Lioncash b1b4487e4d A64: Implement UQSHL (immediate)'s scalar variant 
Like SQSHL's immediate scalar variant, we can also implement UQSHL's
immediate scalar variant in terms of the vector variant for the time
being.
 2020-04-22 21:00:47 +01:00
Lioncash 3649dc6d9a A64: Implement scalar variant of SQSHL (immediate)

Lioncash 7d535eaba6 ir_opt/a32_constant_memory_reads_pass: Apply const where applicable to locals

Lioncash e1b4ff1068 simd_scalar_shift_by_immediate: Migrate SQSHL implementation to file-scope function 
This will allow it to be reused for the implementation of UQSHL.

Lioncash b37279f65c backend/x64/emit_x64_vector: Prevent undefined behavior within VectorSignedSaturatedShiftLeft 
Avoids undefined behavior by potentially left-shifting a signed negative
value.
 2020-04-22 21:00:47 +01:00
Lioncash 46eae8cf2f common/fp/op/FPRecipExponent: Prevent undefined behavior from shifting a negative value 
Due to promotion rules (types < int, even if unsigned, get promoted to
int when arithmetic is performed on them), this is a potential spot for
undefined behavior.

 2020-04-22 20:58:12 +01:00
Lioncash 28a8b4d210 A64: Handle half-precision floating point in scalar FMOV 
This is simply performing a scalar value transfer between registers
without conversions, so this is trivial to handle as-is.

Lioncash d7ac5a664f A64: Handle half-precision floating point in FCVTL 
Like FCVTN, now that we have half-precision floating point conversion
functions available, we can go ahead and use those to eliminate the
interpreter fallback.
 2020-04-22 20:58:12 +01:00
Lioncash fe84ecb780 A64: Handle half-precision floating point in scalar FABS 
Now that we have the half-precision variant of the opcode added, we can
simply handle the instruction instead of treating it as undefined.
