17 months ago[WoA] Use fences for sequentially consistent stores/writes
Nadeem, Usman [Mon, 23 Jan 2023 19:13:58 +0000 (11:13 -0800)]
[WoA] Use fences for sequentially consistent stores/writes

LLVM currently uses LDAR/STLR and variants for acquire/release
as well as seq_cst operations. This is fine as long as all code uses
this convention.

Normally LDAR/STLR act as one way barriers but when used in
combination they provide a sequentially consistent model. i.e.
when an LDAR appears after an STLR in program order the STLR
acts as a two way fence and the store will be observed before
the load.

The problem is that normal loads (unlike ldar), when they appear
after the STLR can be observed before STLR (if my understanding
is correct). Possibly providing weaker than expected guarantees if
they are used for ordered atomic operations.

Unfortunately in Microsoft Visual Studio STL seq_cst ld/st are
implemented using normal load/stores and explicit fences:
dmb ish + str + dmb ish
ldr + dmb ish

This patch uses fences for MSVC target whenever we write to the
memory in a sequentially consistent way so that we don't rely on
the assumptions that just using LDAR/STLR will give us sequentially
consistent ordering.

Thus, to remove duplication, let's move this option
to the top-level configuration of clang-tidy (since
it's something all checks should share).

Since the checks fetch the option via getLocalOrGlobal,
the behavior is unchanged.

Add a deprecation notice for all checks that use the
local option, prompting to update to the global option.

The functionality for parsing the option will need to
remain in the checks during the transition period.
Once the local options are fully removed, the goal
is to store the parsed options in the ClangTidyContext,
that checks can easily have access to.

AMDGPU: Clean up LDS-related occupancy calculations

Occupancy is expressed as waves per SIMD. This means that we need to
take into account the number of SIMDs per "CU" or, to be more precise,
the number of SIMDs over which a workgroup may be distributed.

getOccupancyWithLocalMemSize was wrong because it didn't take SIMDs
into account at all.

At the same time, we need to take into account that WGP mode offers
access to a larger total amount of LDS, since this can affect how
non-power-of-two LDS allocations are rounded. To make this work
consistently, we distinguish between (available) local memory size and
addressable local memory size (which is always limited by 64kB on
gfx10+, even with WGP mode).

This change results in a massive amount of test churn. A lot of it is
caused by the fact that the default work group size is 1024, which means
that (due to rounding effects) the default occupancy on older hardware
is 8 instead of 10, which affects scheduling via register pressure
estimates. I've adjusted most tests by just running the UTC tools, but
in some cases I manually changed the work group size to 32 or 64 to make
sure that work group size chunkiness has no effect.

[AMDGPU] Tune scheduler on GFX10 and GFX11 for regions with spilling

Unlike older ASICs GFX10+ have a lot of VGPRs. Therefore, it is possible
to achieve high occupancy even with all or almost all addressable VGPRs
used. Our scheduler was never tuned for this scenario. The VGPR Critical
Limit threshold always comes very high, even if maximum occupancy is
targeted. For example on gfx1100 it is set to 192 registers even with
the requested occupancy 16. As a result scheduler starts prioritizing
register pressure reduction very late and we easily end up spilling.

This patch makes VGPR critical limit similar to what we would have on
pre-gfx10 targets with much more limited VGPR budget while still trying
to maintain occupancy as it does now.

Pre-gfx10 ASICs shall not be affected as the limit shall be the same
as before, and on gfx10+ it shall only affect regions where we have
to spill.

[AArch64] Check 128-bit Sysreg Builtins

This patch contains several related changes:

1. We move to using TARGET_BUILTIN for the 128-bit system register
   builtins to give better error messages when d128 has not been
   enabled, or has been enabled in a per-function manner.

2. We now validate the inputs to the 128-bit system register builtins,
   like we validate the other system register builtins.

3. We update the list of named PSTATE accessors for MSR (immediate), and
   now correctly enforce the expected ranges of the immediates. There is
   a long comment about how we chose to do this to comply with the ACLE
   when most of the PSTATE accessors for MSR (immediate) have aliased
   system registers for MRS/MSR which expect different values. In short,
   the MSR (immediate) names are prioritised, rather than falling-back
   to the register form when the value is out of range.

[mlir] fix outdated assert in affine symbol verification

The verification of affine value classification for symbols was
expecting, incorrectly, that the dimension operand of `memref.dim` was
being produced by a constant-like operation. This is legacy of the
dimension being an attribute originally, and was never updated after it
was switched to be an operation. Treat such cases conservatively and
classify the value as non-symbol.

A more advanced version could attempt to check that the value would be a
valid symbol for all possible values the dimension attribute could take,
but this does not seem immediately useful.
