Ryan Houdek c6385093eb Adds a few new IR ops 
VectorZero, useful to generate a zero vector without any previous
dependencies

and comparisons with zero which ARM supports faster versions of

Ryan Houdek 04d2d70e51 Implements LZCNT unit test 
Verified correct with the hsot unit test runner

Ryan Houdek 84936e6297 Implements ABM's LZCNT instruction 
This overlaps the previous BSR instruction which is why the table had to
be changed.

We were accidently claiming support for ABM in CPUID before so that
didn't need to be changed.

We now implement both LZCNT and TZCNT so we fully support ABM now.

Ryan Houdek c72d50a9c6 Implements the couple of duplicated ops 
SAL is exactly the same as SHL
TEST is exactly the same as the previous TESTs
Bit silly of encodings since compilers will never actually generate
these

No unit tests on these since getting nasm to emit it is a PITA

Stefanos Kornilios Mitsis Poiitidis d5d0899d5f Merge pull request #421 from Sonicadvance1/fix_mov_mem_offset 
Fixes move with mem offset

Ryan Houdek 811e956df5 Fixes move memoffset tests to have address size override prefix 
Required for the 32bit literal offset
 2020-09-23 10:43:20 -07:00
Ryan Houdek f5a7a3deec Fixes move with mem offset 
Move with mem offset defaults to 64bit offset and the literal size is
changed based on address size override rather than operand size
override.

Operand size override still works in this case, but only for the
register being passed in.

Ryan Houdek a4f92b8564 Removes some undefined behaviour in f2xm1 unit test 
If the input range is outside of -1.0 to +1.0 then the result is
undefined.
To avoid precision problems just check for zero, aka 2^0-1 which also
returns zero

Ryan Houdek aef0f81a23 Ensures eflags matches real state 
0x2 is the default state for hardware boot, but it isn't the state we
boot applications in.

When an application boots under Linux it is actually set to 0x202
because interrupts have been enabled.
Since we can't disable interrupts we will just always have at least
0x202 in the eflags.

This modifies the unit tests to first clear the full eflags state then
loads it so we hit "default". Once we hit the unit test runner we won't
have known the eflags state at that point, so we need to clear it
initially.

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
