Somewhere there was an assumption made that INC and DEC supported the
repeat prefix. This isn't actually the case, while the prefix can be
encoded, it is a nop and should only expect to be used for padding.
Adds a unittest to ensure that behaviour is as expected.
Runs through all immediate encodings for vpblendw and crcs the results
to ensure correct behaviour. This was just a concern because of the typo
in documentation. But it is also good to have.
When AFP is supported then we can actually support DAZ. This might also
fix the audio corruption in Animal Well but I can't test it until Steam
is running on Oryon. Requires a bit of plumbing for MXCSR which we were
hacking around before but now we actually want to store the value.
Fixes#3856
This was doing a 128-bit load from memory and then a 64-bit zero extend
which looked like a spurious move but it was trying to match the
behaviour of vmovq where it needed the zero extend.
Also adds a unit test to ensure that we aren't loading too much data by
loading right up against a page boundary.
Fixes#3787
this fails on current main with blocksize=500 due to mentioned RA bug. passes
with blocksize=1.

At the moment we always run ctest with max number of cpus. If
undefined, it will keep current behaviour, otherwise it will
honour TEST_JOB_COUNT.
Therefore to run ctest one test at a time, use
`cmake ... -DTEST_JOB_COUNT=1`
We had failed to enable these implementations for the
`ExtendedMemOperand` helpers. We had already implemented the non-helper
forms, which are already tested in CI. These helpers just weren't
updated?
Noticed this when running libaom's SSE4.1 tests, where it managed to
execute a pmovzxbq instruction with reg+reg memory source and was
breaking the test results.
There are /very/ few vector register operations that access only 8-bit
or 16-bit in vectors so this flew under the radar for quite a while.
Fixes their unit tests.
Also adds a unittest using sse4.1 pmovzxbq to ensure we support the
reg+reg case, and also a few other instructions to test 8-bit and 16-bit
vector loads and stores.
We didn't have a unit test for this and we weren't implementing it at
all.
We treated it as vmovhps/vmovhpd accidentally. Once again caught by the
libaom Intrinsics unit tests.
When the source or destination is a register, the address size override
doesn't apply. We were accidentally applying it on all sources
regardless of type which was causing us to zero extend on operations
that aren't affected by address size override.
This fixes the OpenSSL cert error in every application, but most
importantly Steam.
