[LTO][CodeMetrics] Count indirect calls as inline candidates when `PrepareForLTO` is set (#192154)

Indirect calls may be resolved during the post-link LLVM pipeline. Thus, count them as potential inline candidates during the pre-link LTO phase.

Git commit 27cc956b00682b5e9162e7325edde51f264d69d6 by GitHub (on behalf of Alexey Bataev) on 03/08/2026 at 17:26..
[SLP]Keep tree-claimed peeled reassociated scalars alive

Peeled scalars are erased unconditionally, but a gather node may still
reference one in its generated buildvector. Keep such scalars (and the
peeled scalars in their operand chains) as plain scalar code.

Fixes #213674

[ConstraintElim] Set NSW on sub when simplifying ssub.with.overflow. (#213532)

When simplifying ssub.with.overflow to a plain sub, we already proven
that the sub does not sign wrap. Replace it with `sub nsw`.

No changes on
https://github.com/dtcxzyw/llvm-opt-benchmark-nightly/pull/842, but
there is very little usage of ssub.with.overflow in default C/C++
builds.

It improves optimizations for code where ssub.with.overflow is used more
widely, like Clang + UBSan or Swift where checked arithmetic is the
default.

A simple C example is https://clang.godbolt.org/z/cv5MbYsrz

Git commit 57965996196ca9caf62784392caf478a9d4133b3 by GitHub (on behalf of Alexey Bataev) on 03/08/2026 at 17:50..
[SLP]Allow unordered fadd reductions with reassoc only

The unordered reduction matcher required isAssociative() for fadd,
i.e. reassoc + nsz, a condition inherited from InstCombine-style
reassociation that also cancels and folds terms. Pure regrouping of
additions cannot change the sign of a zero result, so nsz is not
needed here: the reduction is seeded with the exact -0.0 identity,
the repeated-value multiplier preserves the sign of zero, and
constant folding is IEEE-exact. Brings the fadd requirement in line
with RecurrenceDescriptor, LV and with fmul, which accept reassoc
alone.

[clang][APINotes] Do not duplicate Escapable and Copyable attributes (#213716)

Applying them when they already present is a wasted allocation and can
also cause trouble in the Swift compiler that can complain about
duplicated attributes.

Git commit 01935196807a3e816580d36616f5ec02ad8e50ef by GitHub (on behalf of Ramkumar Ramachandra) on 03/08/2026 at 18:04..
Partial-revert "[IR] Make semantics of strictfp consistent v2" (#213723)

This partially reverts 15bb4a97a7 ([IR] Make semantics of strictfp
consistent v2, #211769) due to a verifier failure in real-world code,
disabling just the verifier-check with a FIXME. The reason for a partial
manual-revert is because a clean revert doesn't apply cleanly: in
particular, the LangRef is untouched by this patch.
