lioncash 4351ec9f4e OpcodeDispatcher: Add helper for retrieving GPR offsets 
Greatly shortens the length of multiple lines. This makes it nicer to
see which register is being loaded or stored.

 2021-11-12 05:53:05 -08:00
lioncash a0eb2eb2e2 Frontend: Mark modrm function LUT as static 
This doesn't need to be constructed on a by-instance basis.
 2021-11-12 08:48:49 -05:00
lioncash d58952d1ef OpcodeDispatcher: Make selection flag enum an enum class 
Makes the enum and member variable strongly typed, so that it's harder
to implicitly use incorrect values.
 2021-11-12 08:41:07 -05:00
lioncash 05ce65322f OpcodeDispatcher: Make X87Tag an enum class 
Makes the tag parameter strongly-typed and prevents implicitly passing
it an incorrect value.
 2021-11-12 08:31:50 -05:00
lioncash 3e5037042f OpcodeDispatcher: Make Segment enum an enum class 
Avoids polluting the surrounding scope.

lioncash 6d82410f44 OpcodeDispatcher: Convert OpType enum into enum class 
Prevents pollution of the surrounding scope a little.
 2021-11-12 08:19:14 -05:00
lioncash 6a79b5cf56 OpcodeDispatcher: Add helper for getting bit sizes 
Allows expressing what we're directly getting instead of needing to
repeat it in several places, given how common this is.
 2021-11-12 08:01:43 -05:00
lioncash 1d88b499e0 OpcodeDispatcher: Handle RORX 2021-11-12 07:28:28 -05:00
lioncash 5d707cf831 OpcodeDecoder: Add support for ADX 
Another CPU extension we can cross off the list.

Addresses #1355
 2021-11-10 12:11:01 -05:00
lioncash 9df8245ef2 OpcodeDispatcher: Implement BMI2 SARX/SHLX/SHRX 
Gets the basic BMI2 shifts out of the way.
 2021-11-07 02:12:06 -05:00
lioncash 7d2b3d0846 CPUID: Signify support for BMI1 
Now that all of BMI1's instructions are implemented, we can signify that
we support it in CPUID.
 2021-11-06 23:37:54 -04:00
lioncash e0973e19fc OpcodeDispatcher: Implement handling for BLSMSK 2021-11-06 23:36:52 -04:00

Ryan Houdek 8b64546579 Merge pull request #1349 from Sonicadvance1/fix_paranoid 
Arm64: Fixes paranoid TSO mode
 2021-11-06 17:24:41 -07:00
Ryan Houdek 61a0508ff6 Arm64: Fixes paranoid TSO mode 
Vector loadstores were crashing. Now we emulate on load and backpatch on
store.

Store can't effectively emulate so it's better to backpatch.
 2021-11-06 04:03:37 -07:00
Ryan Houdek 4ebbca45be CPUID: Adds support for hybrid flag 
CPUID lets the application know if it is running on a CPU with hybrid
CPU clusters.
This matches big.little fairly easily. Walk the affinity mask and
check if we are running on a big.little system and report it to the
guest.

For x86-64 host just pass through the flag.
 2021-11-06 03:01:39 -07:00
lioncash b47cb20619 OpcodeDispatcher: Implement handling for BLSI 
Now all that remains is handling for BLSMSK and BLSR
 2021-11-04 18:49:15 -04:00
lioncash 166c96320c Frontend: Handle VEX-encoded destination operands 
BLSI, BLSMSK, and BLSR make use of these, for example.
 2021-11-04 17:52:57 -04:00
lioncash e317424b86 X86Tables: Increase InstFlags to uint64_t 
We've run out of the range of 32 bits already and will need to use
another flag in upcoming changes, so we need to expand our flags to be
64-bit.

While we're at it, we can use a dedicated type alias for the instruction
flags to make the interface changeable from one spot in the future.

Ryan Houdek babb81a240 Merge pull request #1343 from Sonicadvance1/sigbus_share 
Arm64: Consolidate HandleSIGBUS
 2021-11-03 01:46:36 -07:00
Ryan Houdek 235367b67a Merge pull request #1342 from Sonicadvance1/tear_telemetry 
Telemetry: Adds telemetry for when an application tears
 2021-11-03 01:46:27 -07:00
Ryan Houdek 5b9da4f2be Arm64: Consolidate HandleSIGBUS 
We can share this between the interpreter and the JIT. Necessary to
support the TSO-correct interpreter path.

With this change the interpreter is TSO-correct for GPRs. Just not FPRs
yet.
 2021-11-02 23:54:25 -07:00
Ryan Houdek 4c712ca111 Telemetry: Adds telemetry for when an application tears 
This can be used as an early indicator of an application doing nefarious
things.

Ryan Houdek 3bcc8ca695 IR: Fixes memory ops having a duplicate size field 
There's zero need for these to have an independent size field and it was
just confusing.
For stores it was always set to zero and for loads it was just
duplicated.

In addition this allows introspection of the store op without casting
the op, which can be useful in edge cases

Ryan Houdek 34b2f93ddf Merge pull request #1338 from lioncash/bic 
IR: Add handling for ANDN operations
 2021-11-02 19:29:29 -07:00
lioncash 49dae08b3d OpcodeDispatcher: Make use of the new Andn IR op where applicable 
Now that we have the handling in place, we can make use of it to
simplify some operations and resolve some lingering TODO comments.
 2021-11-02 21:59:56 -04:00
lioncash 0b700de7d9 IR: Add handling for ANDN operations 
This is a pretty straightforward operation that can be nicely modeled
by the BIC instruction on ARMv8, which is nice since we can get rid of
the need to manually perform the And and Not operations.

Ryan Houdek 76538be0e0 Merge pull request #1337 from lioncash/bmi-bextr 
OpcodeDispatcher: Handle BMI1 BEXTR
 2021-11-02 18:26:52 -07:00
lioncash 002867bc2a Core: Mark relevant Interpreter/JIT functions as [[nodiscard]] 
Lets the compiler warn loudly when the result from any of these
functions are left unused (indicating a bug).

Lioncash f088f0a236 Frontend: Handle VEX source operands 
This will allow us to begin implementing BMI instructions.

Ryan Houdek a40a0cbb12 Interpreter: Splits ops in to separate files 
I need this for something else so I'm doing this now

Ryan Houdek 435137e1a2 JIT: Fixes asserts added to the JIT 
Fixes #1319
 2021-10-19 10:42:55 -07:00
Ryan Houdek d847f6e1b3 JITSymbols: Allow grouping JIT symbols by guest named regions 
This lets us have JITsymbols grouped by library.
Useful for determining where to thunk.

Sadly perf doesn't have an option to deduplicate regions by name, so
some external tooling is necessary to make it look nice.
 2021-10-16 21:10:57 -07:00
Ryan Houdek 1d9b66044a JITSymbols: Change over to runtime enablement of symbols 
Adds a new option for just describing all JIT state as a single symbol.
Useful for simple profiling of total time spent in the JIT
 2021-10-13 17:48:34 -07:00
Lioncash c9621da51c OpcodeDispatcher: Deduplicate OpToIndex definition 
We can just make the one defined in X86Tables visible instead to keep
everything in one spot.
