Stefanos Kornilios Mitsis Poiitidis 208dc794e8 Merge pull request #64 from Sonicadvance1/more_syscalls 
Implements more syscalls that I found while running applications
 2020-03-22 08:58:39 +02:00
Ryan Houdek f89ef01578 Implements the COMISS instructions 
These are fairly popular so not having them around is causing headaches.
We will really want these in the future to use the host register, btu
that is more time consuming than I want to dedicate to at the moment.

So the FCMP instruction must be told which flags to generate up front,
then it generates the flags in to a GPR which are then tracked and
pulled out with a specific IR op.

This can be augmented in the future to more easily RA the host flag
register

Ryan Houdek b948be7ad8 Implements more syscalls that I found while running applications

directly

Adds hypervisor CPUID function
 2020-03-21 09:22:32 +02:00
Ryan Houdek 6de60bea70 Fixes FRSQRT in AArch64 
fmov (vector, immediate, broadcast) keys register size based on the
float/double constant passed in

So since 1.0f was missing the f, it was passed as a double, duplicating
64bit doubles rather than 32bit floats
 2020-03-20 19:49:05 -07:00
Ryan Houdek 2bc7c28a9c Fixes AArch64 ROL implementation 
In the case that RA does Dst = Src[1] then we would have overwrote our
shift value. Move the negation to the top of the 8bit and 16bit ROL to
make sure that doesn't happen
 2020-03-20 18:58:39 -07:00
Ryan Houdek 76d67812ed Implements 64bit RSQRT and fixes vector 32bit RSQRT in the x86 JIT. 2020-03-20 18:14:44 -07:00

Ryan Houdek ca36fd4523 Fixes a couple bugs in the futex syscall 
futex command 9 is actually WAIT_BITSET, not WAKE_BITSET
Implements futexes with timeouts as well, necessary for anything using
std::condition_variable and wait_for/wait_until
 2020-03-20 17:32:37 -07:00
Ryan Houdek ea167cf7d9 Adds a few new syscalls that I saw in app testing 
madvise, dup, bind, syslog, getresuid, get_mempolicy, newfstatat, execve

execve specifically returned error. We don't support it yet.

Ryan Houdek 8e06765101 Throws a mutex in CompileBlock until we properly handle threaded compilation. 
This is purely a workaround until it gets implemented correctly
 2020-03-20 12:25:14 -07:00
Ryan Houdek c44da5d3eb Implements and fixes flag setting in a few instructions 
A few instructions were missing flag setting entirely or were generating
wrong flags
  - ROL, ROR, SHL, SHR, ASHR, SHLD, SHRD, CMPXCHG

This fixes those instructions and removes a few outdated comments
Specifically noticed when trying to run xcalc, it was using the flag
results from SHL for something and crashed without flag setting.

Unit tests for RFLAG setting instructions is still forthcoming
 2020-03-20 12:22:00 -07:00
Ryan Houdek a059fc1943 Adds hypervisor CPUID function 
4000'0000h is the hypervisor CPUID information leaf, can just return all
zeroes to imply we aren't running under a hypervisor

EAX: The maximum input value for CPUID supported by the hypervisor.
     - We return zero here to signify no Hypervisor
EBX, ECX, EDX: Vedor ID signature

CPUID 4000'0001h - 4000'000Fh is reserved for hypervisor, which we don't
need to expose since we return zero in EAX

Ryan Houdek 9c24a92f73 Makes sure DCE pass doesn't remove print IR op 
This is useful for debugging, don't want the DCE pass to remove it

LLVM 9 fixes
 2020-03-18 11:05:40 -07:00
Ryan Houdek fc452de973 Some more fixes for LLVM picked up from the AArch64 side

Ryan Houdek 2e0851975f Makes sure LLVM on AArch64 can read the cycle counter 2020-03-17 19:28:08 -07:00
Ryan Houdek d6fb1f2d17 Make sure OpDispatcher is using explicit scalar operations 
LLVM specifically gets really picky if you mix vector and scalar ops.
Additionally AArch64 seems to be even pickier than x86 for this
 2020-03-17 19:27:58 -07:00

Ryan Houdek 90c4b3dae7 Merge pull request #33 from Sonicadvance1/minor_x86_vsqxtun 
Minor optimization in vsqxtun for x86
 2020-03-17 17:01:18 -07:00
Ryan Houdek 388e723c78 Fixes shift ops in LLVM9 
These don't need to operate at 128bit, just one size larger than
incoming.
This is because of 8bit and 16bit shifts rely on 32bit size masking
rather than 8bit and 32bit, so they have to shift at a larger size due
to ensure correct behaviour(that is not undefined).
LLVM-8 worked with the previous behaviour but broke with LLVM-9.
So changing it to this slightly smarter code gen.
 2020-03-17 13:52:23 -07:00
Ryan Houdek 16382c4202 Fixes Scalar FCMP in LLVM9

scalar source

Found with BT test ops
 2020-03-17 09:26:52 -07:00
Ryan Houdek 21e9ec5f8a Fixes BT ops masking bit selection on GPR destination 
When the destination is a GPR instead of a memory location then the
source bitselect register is masked by the size of the operation
