[AArch64] Disallow vector operand if FPR128 Q register is required.

Patch https://reviews.llvm.org/D41445 changed the behaviour of 'isReg()'
to also return 'true' if the parsed register operand is a vector
register. Code in the AsmMatcher checks if a register is a subclass of the
expected register class. However, even though both parsed registers map
to the same physical register, the 'v' register is of kind 'NeonVector',
where 'q' is of type Scalar, where isSubclass() does not distinguish
between the two cases.

The solution is to use an AsmOperand instead of the register directly,
and use the PredicateMethod to distinguish the two operands.

This fixes for example:
  ldr v0, [x0]    // 'v0' is an invalid operand for this instruction
  ldr q0, [x0]    // valid

Revert r330742: Let TableGen write output only if it changed, instead of doing so in cmake.

This change causes us to re-run tablegen for every single target on
every single build. This is much, much worse than the problem being
fixed AFAICT.

On my system, it makes a clean rebuild of `llc` with nothing changed go
from .5s to over 8s. On systems with less parallelism, slower file
systems, or high process startup overhead this will be even more
extreme.

The only way I see this could be a win is in clean builds where we churn
the filesystem. But I think incremental rebuild is more important, and
so if we want to re-instate this, it needs to be done in a way that
doesn't trigger constant re-runs of tablegen.

[llvm-rc] Exclude padding from sizes in versioninfo resources

Normally when writing something that requires padding, we first
measure the length of the written payload data, then write
padding if necessary.

For a recursive structure like versioninfo, this means that the
padding is excluded from the size of the inner element, but
included in the size of the enclosing block.

Rc.exe excludes the final padding (but not the padding of earlier
children) from all levels of the hierarchy.

To achieve this, don't pad after each block or value, but only
before starting the next one. We still pad after completing the
toplevel versioninfo resource, so this won't affect other resource
types.

all together,   it's only used to hold and reclaim the memory for the allocated

[AMDGPU] Don't force WQM for DS op

Previously, all DS ops forced WQM in a pixel shader. That was a hack to
allow for graphics frontends using ds_swizzle to implement explicit
derivatives, on SI/CI at least where DPP is not available. But it forced
WQM for _any_ DS op.

(Mesa and LLPC) need to change to issue an explicit llvm.amdgcn.wqm
intrinsic call when calculating explicit derivatives.

The required Mesa change is: "amd/common: use llvm.amdgcn.wqm for
explicit derivatives".

6 years ago[globalisel] Update GlobalISel emitter to match new representation of extending loads
Daniel Sanders [Sat, 5 May 2018 20:53:24 +0000 (20:53 +0000)]
[globalisel] Update GlobalISel emitter to match new representation of extending loads

Summary:
Previously, a extending load was represented at (G_*EXT (G_LOAD x)).
This had a few drawbacks:
* G_LOAD had to be legal for all sizes you could extend from, even if
  registers didn't naturally hold those sizes.
* All sizes you could extend from had to be allocatable just in case the
  extend went missing (e.g. by optimization).
* At minimum, G_*EXT and G_TRUNC had to be legal for these sizes. As we
  improve optimization of extends and truncates, this legality requirement
  would spread without considerable care w.r.t when certain combines were
  permitted.
* The SelectionDAG importer required some ugly and fragile pattern
  rewriting to translate patterns into this style.

This patch changes the representation to:
* (G_[SZ]EXTLOAD x)
* (G_LOAD x) any-extends when MMO.getSize() * 8 < ResultTy.getSizeInBits()
which resolves these issues by allowing targets to work entirely in their
native register sizes, and by having a more direct translation from
SelectionDAG patterns.

Each extending load can be lowered by the legalizer into separate extends
and loads, however a target that supports s1 will need the any-extending
load to extend to at least s8 since LLVM does not represent memory accesses
smaller than 8 bit. The legalizer can widenScalar G_LOAD into an
any-extending load but sign/zero-extending loads need help from something
else like a combiner pass. A follow-up patch that adds combiner helpers for
for this will follow.

The new representation requires that the MMO correctly reflect the memory
access so this has been corrected in a couple tests. I've also moved the
extending loads to their own tests since they are (mostly) separate opcodes
now. Additionally, the re-write appears to have invalidated two tests from
select-with-no-legality-check.mir since the matcher table no longer contains
loads that result in s1's and they aren't legal in AArch64 anymore.

[MachineLICM] Debug intrinsics shouldn't affect hoist decisions

Summary:
When checking if an instruction stores to a given frame index, check
that the instruction can write to memory before looking at the memory
operands list to avoid e.g. DBG_VALUE instructions that reference a
frame index preventing a load from that index from being hoisted.

[ObjCARC] Account for catchswitch in bitcast insertion

A catchswitch is both a pad and a terminator, meaning it must be the
only non-phi instruction in its basic block. When we're inserting a
bitcast in the incoming basic block for a phi, if that incoming block is
a catchswitch, we should go up the dominator tree to find a valid
insertion point rather than attempting to insert before the catchswitch
(which would result in invalid IR).
