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

Adds hypervisor CPUID function

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 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 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 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

 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.

scalar source
