Merge pull request #9494 from Dentomologist/convert_arm64reg_to_enum_class
Arm64Gen: Convert ARM64Reg to enum class
2021-03-17 00:05:23 +01:00
Dentomologist f0f206714f Arm64Gen: Convert ARM64Reg to enum class
Most changes are just adding ARM64Reg:: in front of the constants.

JosJuice 9ad4f724e4 Arm64Emitter: Use ORR in MOVI2R 2021-02-13 21:04:13 +01:00
JosJuice 0d5ed06daf Arm64Emitter: Improve MOVI2R
More or less a complete rewrite of the function which aims
to be equally good or better for each given input, without
relying on special cases like the old implementation did.

In particular, we now have more extensive support for
MOVN, as mentioned in a TODO comment.

JosJuice d226b8f825 Arm64Emitter: Remove optimize parameter from MOVI2R
I don't really see the use of this. (Maybe in the past it
was used for when we need a constant number of instructions
for backpatching? But we don't use MOVI2R for that now.)

MerryMage 9753f21cc7 Arm64Emitter: Remove unsequenced expressions
Incrementing `it` twice between sequence points is undefined behavior.

Lioncash 208be26bb4 Arm64Emitter: Make the Align* functions return a non-const data pointer
Similar in nature to e28d063539 in which
this same change was applied to the x64 emitter.

There's no real requirement to make this const, and this should also
be decided by the calling code, considering we had places that would
simply cast away the const and carry on

Lioncash 67b015d76b Arm64Emitter: Get rid of a pointer cast within SetJumpTarget()
Type punning like this is undefined behavior. Instead, we use std::memcpy to
copy the necessary data over, which is well defined (as it treats both
the source and destination as unsigned char).
2018-08-14 23:47:53 -04:00
Lioncash 6fd7a79b93 Arm64Emitter: Use Common::BitCast where applicable
Gets rid of the need to set up memcpy boilerplate to reinterpret between
floating-point and integers.

While we're at it, also do a minor bit of tidying.

These aren't used anywhere outside of the emitter. Centralizes them under an anonymous namespace.

Arm64Emitter: Remove unnecessary V8_UINT64_C preprocessor macro
UINT64_C is provided via <cstdint>, so we can just use that instead.

Lioncash 7926a0c814 Use __func__ instead of __FUNCTION__ where applicable
This replaces usages of the non-standard __FUNCTION__ macro with the standard
mandated __func__ identifier.

__FUNCTION__ is a preprocessor definition that is provided as an
extension by compilers. This was the only convenient option to rely on
pre-C++11. However, C++11 and greater mandate the predefined identifier
__func__, which lets us accomplish the same thing.

The difference between the two, however, is that __func__ isn't a
preprocessor macro, it's an actual identifier that exists at function
scope. The C++17 draft standard (N4659) at section [dcl.fct.def.general]
paragraph 8 states:

"
The function-local predefined variable __func__ is defined as if a
definition of the form

static const char __func__[] = "function-name ";

had been provided, where function-name is an implementation-defined
string. It is unspecified whether such
a variable has an address distinct from that of any other object in the
program.
"

Thankfully, we don't do any macro or string concatenation with __FUNCTION__
that can't be modified to use __func__.

Lioncash 75f5fcdfee Assert: Remove unused parameter from DEBUG_ASSERT
This brings the macro in line with the regular ASSERT macro, which only has one
macro parameter.

Lioncash 50a476c371 Assert: Uppercase assertion macros
Macros should be all upper-cased. This is also kind of a wart that's
been sticking out for quite a while now (we avoid prefixing
underscores).

Jonathan Hamilton 8ae76a6680 Fix arm64 MOVI2R for addresses between 2gb and 4gb offset from PC
The PC offset ADRP() path takes a s32 value, but the input offset was
being tested as abs(ptr) < 0xFFFFFFFF. This caused values between
0x80000000 and 0xFFFFFFFF to incorrectly use this path, despite the
offsets not being representable in an s32.

This caused a crash in the VertexLoader on android 8.1 immediate in wind
waker (and possibly all other apps on android 8.1) as the jit and data
sections happened to be loaded 4gb apart in virtual memory, causing some
pointers to hit this

degasus 304e601ad3 JitArm64: Reimplement aarch64 cycle counters.
CNTVCT_EL0 is force-enabled on all linux plattforms.
Windows is untested, but as this is the best way to get *any* low
overhead performance counters, they likely use it as well.

degasus b00c60618b JitArm64: Fix rlwinmx.
Seems like I was wrong that ANDI2R doesn't require a temporary register here.
There is *one* case when the mask won't fit in the ARM AND instruction:
mask = 0xFFFFFFFF
But let's just use MOV instead of AND here for this case...
