Ryan Houdek 085fca01bc Core: After fork make sure to cleanup stacks 
After FEX has forked, there aren't any other threads in the process but their stacks remain.
We need to have some book keeping in place to have the stack ranges available to clean up
after fork.

We now keep both live stacks and dead stacks in a dequeue and on fork we will walk both to
clean up all stack objects that aren't our current thread.

Core: return unique_ptr by default for cores

Lioncash 6c5abc8819 Core: Make CustomCPUFactory instances return unique_ptr 
Makes the ownership intentions of the function explicit.

Lioncash f36726ecf6 Core: return unique_ptr by default for cores 
Communicates ownership semantics in the API.

Lioncash 9ed0572fa4 IRParser: Make use of unique_ptr for Parse() 
Communicates ownership semantics to the user of the API a little better,
and makes it harder to accidentally leak memory.

Ryan Houdek d57a034220 Fixes floating point conversion rounding bugs 
When floats and doubles were converting to integers we weren't doing the correct transformation.
AArch64 provides direct ops for all four of the op types. So lets use them
  - f32 -> int64
  - f32 -> int32
  - f64 -> int64
  - f64 -> int32

Doesn't fully fix the case of overflow for AArch64 since overflow behaviour is different.
x86 returns 0x8000'0000 or 0x8000'0000'0000'0000 while AArch64 saturates to the maximum signed
integers. Can't work around that without checking overflow flags.

This does solve the typical case though.
Fixes audio problems in all FMod games.

Ryan Houdek 748c3182a7 Fixes a typo in interpreter LSHL 
This was causing uint32_t pointers to sign extend on 32-bit
New tests being run were hitting this when we were expecting them to zero extend

Ryan Houdek dfc454873c Moves AOTIR cache queue object to be inside the context 
This fixes a crash that occurs due to mixing memory allocators.
This PR has tickled the allocation just enough that it broke

Ryan Houdek fec078f924 Fixes bug in interpreter VInsGPR 
If the source GPR had data that was larger than the element it would overwrite other elements
Mask it correctly. This then matches behaviour with the other CPU backends

Ryan Houdek 7b2b2a3d07 Implements all the remaining SSE4.1 instructions 
Theres a fair number of these so I won't describe them all.

A couple highlights are MPSADBW and PHMINPOSUW.
These don't really match with AArch64 very well so their IR is a bit ugly.

Ryan Houdek 02abbd216a Fixes an issue with debug printing vectors 
We need to save the vector registers otherwise we will corrupt them.
Also in the case of printing a vector register, fall down the specialized path

Only useful when debugging

Ryan Houdek 8b7a7e91c9 Implements new IR ops 
Adds VBic, VUMinV, VPopcount, VUnZip, VUnZip2, VDupElement, Vector_FToI, and VUABDL

accident.

Lioncash 37e2210f64 DecodedOperand: Convert operand type into an enum class 
Now possible in a less messy way, since the type is now centralized in
one location.

Makes it strongly typed and prevents any potential accidental implicit
assignments to Type instead of something intended for the Data members.
 2021-06-02 06:51:15 -04:00
Lioncash 1f0bc49e54 DecodedOperand: Add helper functions for type testing 
Significantly shortens the amount of code necessary for testing the type
of a decoded operand.

Also relocates the type field out of all the union types to have it in a
central location.

Ryan Houdek 2d342d4662 Handle user provided siginfo_t with user signal 
If the guest has sent a signal and the si_code is SI_USER then
we need to pass that siginfo_t through without touching it.
User could be sticking whatever they want in to that struct
