Ryan Houdek a69b700afb Support setting emulator host rounding mode with ldmxcsr/stmxcsr 2020-09-23 00:21:52 -07:00

Stefanos Kornilios Mitsis Poiitidis 91bea781f4 Merge pull request #408 from Sonicadvance1/rounding_mode_host 
Adds new IR ops for supporting host rounding mode conversion
 2020-09-23 09:50:37 +03:00
Ryan Houdek 74e2f189f1 Implements MASKMOVQ and MASKMOVDQU 
Without supporting phis this entire loop needs to be unrolled.

I just found out while reading the x86 documentation that this
instruction is explicitly a weakly ordered memory operation.
So this operation can be changed over to a couple vector conditional
loadstores soon after merging

Ryan Houdek adb9b111ca Fixes crash when SSA value has size of zero 
In the case of an invalid SSA destination size, the IR validation pass
would catch it and then when printing the IR it would crash with a
divide by zero.
Fixes that.

Ryan Houdek 78ad2e4781 Fixes incorrect assuming BT tests 
66 prefix /does/ change behaviour because that is the operand size
prefix.

Additionally the immediate variant will also modulo the result.
So that needs to be checked for

Confirmed with manual on upcoming host-side unit test runner

Ryan Houdek 5bd02fb003 Fixes CASP IR op on interpreter when unified memory is enabled 
Noticed by Stef on 09/09/2020 as a curious code block that was failing
Forgot about it until now since we couldn't see exactly where it was
wrong

Code block was mixing x87 (Which forces a fallback to Interpreter) and
cmpxchg8b, which caused that code block to fail.

Since this op was broken with Unified Memory + Interpreter it wasn't
picked up by unit tests since those don't run in unified memory

Ryan Houdek e194aa28e4 Removes a couple of unnecessary variables to improve reentrancy chances 
We still aren't 100% reentrant safe in the case that the cores are
interrupted while running, but this is a step in the right direction

Scott Mansell 5048753e37 Undo limitation of ASHR to 32/64bit 
This should really be done later in a sperate PR.

 1. We don't have proper unit test coverage
 2. I still didn't get this right at time of removal
 3. I haven't done the jit changes to go along with this.

Ryan Houdek 806753fa43 Fixes address size override prefix 
We were handling this in a completely broken fashion and it only broke
more with the previous zexting changes.

This fixes the EXPLICIT address size override usage.
There are still a few instructions that rely on implicit address size
override support that this doesn't handle

Ryan Houdek d0de92f97a Removes error and die in multithreaded forks 
This can result in some terrible behaviour if something doesn't
immediately execve once it forks. Allow it instead of crashing out
though.

Ryan Houdek ddecec12ec Spam out a wackload more syscalls 
Almost all of these end up being simple passthrough.
This covers most syscalls, the remaining ones are signal related, exec
related, or rseq required.

All of these syscalls exist prior to Linux 5.0. We are using these with
the expectation still that the host Linux implementation is 5.0 or
higher.
Once we implement newer syscalls we will need to start checking for host
Linux version. We don't really have a care about devices shipping older
4.x kernels atm.
