Stefanos Kornilios Mitsis Poiitidis 56d10dcbbb IR: Make OP_THUNK use an inline sha256 hash of the thunk name, update thunk scripts 2021-02-23 12:08:57 +02:00
Ryan Houdek 8a39f4b25c Implements BTC, BTR, BTS atomic unit tests 
This just takes the regular non-atomic unit tests and changes them to
have lock prefixes.
These are all handled as byte sized atomics so there aren't any
alignment problems.

Ryan Houdek 633ea045e5 Handles unaligned cmpxchg/cmpxchg8b in SIGBUS handler 
cmpxchg/cmpxchg8b doesn't have alignment requirements on x86, which means
applications rely on unaligned behaviour support with it.

Steam relies on this to work for a linked list array of jobs in some
internal job queueing system. It will end up always aligning by offsets
of 4 since it stores a couple of pointers.

Doesn't currently support the case of unaligned cmpxchg8b crossing a
cacheline, which ends up being semi-broken depending on which x86
behaviour the application is expected.
Intel CPUs do the "Big ring lock" or "split locks". Which means accesses
across cachelines are atomic.
AMD CPUs will tear the value across the cacheline, which is expected x86
behaviour by spec.

If they are expecting Intel behaviour, then that application is just
broken on non-Intel platforms unless they are fine with a tear.

Ryan Houdek 0c7c7ba670 Removes undefined behaviour in our unit tests 
Most of these were relying on the upper 16bits of the 80bit MM registers
to be zero.
This isn't necessarily true as one will find out when running this under
the host runner.
