[llvm-branch-commits] [msan] Implement shadow propagation for _mm_dp_pd, _mm_dp_ps, _mm256_dp_ps (PR #94875)

[Vitaly Buka via llvm-branch-commits]

https://github.com/vitalybuka created 
https://github.com/llvm/llvm-project/pull/94875

Default intrinsic handling was to report any
uninitialized part of argument. However intrinsics
use mask which allow to ignore parts of input, so
it's OK to have vectors partially initialized.

`blendv` instructions are very similar to `select`.
We will add support for them in followup patches.

Then are very similar to select, so we adjust
arguments and forward them into select handler.

Not exactly. Input bits can affect particular output bits.
E.g. argument with single uninitialized bit can be multiplied by initialized 
zero.
So it's approximation, but better checking will be expensive.

According to https://reviews.llvm.org/D114250
this was to handle Mac specific issue, however
the test is Linux only.

The test effectively prevents to lock main allocator
on fork, but we do that on Linux for other
sanitizers for years, and need to do the same
for TSAN to avoid deadlocks.

[llvm-branch-commits] [InstCombine][asan] Don't speculate loads before `select ptr` (PR #100773)

[Vitaly Buka via llvm-branch-commits]

https://github.com/vitalybuka created 
https://github.com/llvm/llvm-project/pull/100773

Even if memory is valid from `llvm` point of view,
e.g. local alloca, sanitizers have API for user
specific memory annotations.

This annotations can be used to track size of the
local object, e.g. inline vector like may prevent
accessed beyond the current vector size.

So valid programs should not access those parts of
alloca before checking preconditions.

Fixes #100639.
