[RISCV] Prefer SP over FP for frame index access when offset fits within compressed immediate range. (#193962)
Before this change, we would use fp/s0/x8 for most stack accesses when
frame pointers were present. This is an over-approximation when a
stack slot is reachable from both SP and FP with no scalable offset.
This patch replaces the unconditional getFrameRegister() call in
getFrameIndexReference with an explicit register selection decision
tree.
When both SP and FP are available (no stack realignment, no RVV objects,
no variable-sized objects), prefer SP if the SP-relative offset fits in
the compressed instruction immediate range (<=252 for RV32, <=504 for RV64).
This enables compression for sp-relative instructions to c.swsp/c.lwsp
(RV32) and c.sdsp/c.ldsp (RV64) thereby reducing code size.
fix hard-to-reach NULL deref during pubkey auth
To hit this, the user must be using a PEM style private key with no
corresponding .pub key adjacent to it.
[mlir][complex] Emit complex.mul multiplications before add/sub lowering (#196231)
[mlir][complex] Emit complex.mul multiplications before add/sub lowering
This changes the lowering of complex.mul in both ComplexToStandard and
ComplexToLLVM to emit the four independent multiplications before
creating the
final add/sub operations.
The lowered computation is unchanged:
real = lhs.real * rhs.real - lhs.imag * rhs.imag
imag = lhs.imag * rhs.real + lhs.real * rhs.imag
but the generated operation order changes from:
mul, mul, sub, mul, mul, add

rpki-client: fix incomplete strncmp() check
The directory path in rp->repouri doesn't end in a '/' itself, so check
that the uri containing an unused file points at something below it.

[clang] make concept normalization a SFINAE context
It is incorrect to allow the substitution failures in concept normalization
to make the program ill-formed.
These can happen when comparing the equivalence of constraints for
redeclaration checking, and a failure here only means these declarations
are not equivalent.
For now, these diagnostics are simply discarded. It would be nice
if some day, as part of diagnostics for non-matching out-of-line definitions,
we would explain why matching failed for each candidate, and then add these
as notes explaining why the constraints were not equivalent.

[LifetimeSafety] Diagnose invalidated-global (#197220)
Teach lifetime safety invalidation diagnostics to handle origins that
escape through global or static storage before the referenced object is
invalidated. Previously they were skipped.

virtio(4): Allow virtio 0.9 BAR0 type to be memory rather than I/O.
This matches virtio>=1.0, and can't break working `hardware': any
existing virtio devices that worked must have reported I/O-type BAR0,
so they will continue to work; this will only enable previously
unusable virtio devices, reporting memory-type BAR0, to work.
Patch from Petri Koistinen.
