5 years ago[ARM] Eliminate redundant "mov rN, sp" instructions in Thumb1.
Eli Friedman [Wed, 20 Mar 2019 19:40:45 +0000 (19:40 +0000)]
[ARM] Eliminate redundant "mov rN, sp" instructions in Thumb1.

This takes sequences like "mov r4, sp; str r0, [r4]", and optimizes them
to something like "str r0, [sp]".

For regular stack variables, this optimization was already implemented:
we lower loads and stores using frame indexes, which are expanded later.
However, when constructing a call frame for a call with more than four
arguments, the existing optimization doesn't apply.  We need to use
stores which are actually relative to the current value of sp, and don't
have an associated frame index.

This patch adds a special case to handle that construct.  At the DAG
level, this is an ISD::STORE where the address is a CopyFromReg from SP
(plus a small constant offset).

This applies only to Thumb1: in Thumb2 or ARM mode, a regular store
instruction can access SP directly, so the COPY gets eliminated by
existing code.

The change to ARMDAGToDAGISel::SelectThumbAddrModeSP is a related
cleanup: we shouldn't pretend that it can select anything other than
frame indexes.

5 years ago[Linker] Fix crash handling appending linkage
Rafael Auler [Wed, 20 Mar 2019 19:20:07 +0000 (19:20 +0000)]
[Linker] Fix crash handling appending linkage

Summary:
When linking two llvm.used arrays, if the resulting merged
array ends up with duplicated elements (with the same name) but with
different types, the IRLinker was crashing. This was supposed to be
legal, as the IRLinker bitcasts elements to match types in these
situations.

This bug was exposed by D56928 in clang to support attribute used
in member functions of class templates. Crash happened when self-hosting
with LTO. Since LLVM depends on attribute used to generate code
for the dump() method, ubiquitous in the code base, many input bc
had a definition of this method referenced in their llvm.used array.
Some of these classes got optimized, changing the type of the first
parameter (this) in the dump method, leading to a scenario with a
pool of valid definitions but some with a different type, triggering
this bug.

This is a memory bug: ValueMapper depends on (calls) the materializer
provided by IRLinker, and this materializer was freely calling RAUW
methods whenever a global definition was updated in the temporary merged
output file. However, replaceAllUsesWith may or may not destroy
constants that use this global. If the linked definition has a type
mismatch regarding the new def and the old def, the materializer would
bitcast the old type to the new type and the elements of the llvm.used
array, which already uses bitcast to i8*, would end up with elements
cascading two bitcasts. RAUW would then indirectly call the
constantfolder to update the constant to the new ref, which would,
instead of updating the constant, destroy it to be able to create
a new constant that folds the two bitcasts into one. The problem is that
ValueMapper works with pointers to the same constants that may be
getting destroyed by RAUW. Obviously, RAUW can update references in the
Module to do not use the old destroyed constant, but it can't update
ValueMapper's internal pointers to these constants, which are now
invalid.

The approach here is to move the task of RAUWing old definitions
outside of the materializer.

Test Plan:
Added LIT test case, tested clang self-hosting with D56928 and
verified it works

[AMDGPU] Allow MIMG with no uses in adjustWritemask in isel

Summary:
If an MIMG instruction has managed to get through to adjustWritemask in isel but
has no uses (and doesn't enable TFC) then prevent an assertion by not attempting
to adjust the writemask.

The instruction will be removed anyway.

[DAGCombine] Fix a miscompile when reducing BUILD_VECTORs to a shuffle

In r311255 we added a case where we split vectors whose elements are
all derived from the same input vector so that we could shuffle it
more efficiently. In doing so, createBuildVecShuffle was taught to
adjust for the fact that all indices would be based off of the first
vector when this happens, but it's possible for the code that checked
that to fire incorrectly if we happen to have a BUILD_VECTOR of
extracts from subvectors and don't hit this new optimization.

Instead of trying to detect if we've split the vector by checking if
we have extracts from the same base vector, we can just pass that
information into createBuildVecShuffle, avoiding the miscompile.

When the other operand is non-constant we fold to a bool constant based on isTrueWhenEqual (handled in SimplifyICmpInst).

Neither is really wrong, but this patch changes the logic in SimplifyICmpInst to consistently fold to undef.

[ValueTracking][InstSimplify] Support min/max selects in computeConstantRange()

Add support for min/max flavor selects in computeConstantRange(),
which allows us to fold comparisons of a min/max against a constant
in InstSimplify. This was suggested by spatel as an alternative
approach to D59378. I've also added the infinite looping test from
that revision here.

The default implementation does we want and is going to more compatible
with dynamic linking (-fPIC) support that is planned.

This is NFC because currently we only build wasm with
`-relocation-model=static` which in turn means that the default
`isOffsetFoldingLegal` always returns true today.
