cause a SIGPIPE signal, but that's expected, and there's no way to turn
this error message off to avoid spurious error messages.
UNIX03 apparently doesn't require printing an error message on SIGPIPE,

of information impacts how the instruction takes to execute and what dependencies this may cause.

[mlir][llvm] Iterative constant import from LLVM IR.
Instead of importing constant expressions recursively, the revision
walks all dependencies of an LLVM constant iteratively. The actual
conversion then iterates over a list of constants and all intermediate
constant values are added to the value mapping. As a result, an LLVM IR
constant maps to exactly one MLIR operation per function. The revision
adapts the existing tests since the constant ordering changed for
aggregate types. Additionally, it adds extra tests that mix aggregate
constants and constant expressions.

The Assignment Tracking debug-info feature is outlined in this RFC:
https://discourse.llvm.org/t/
rfc-assignment-tracking-a-better-way-of-specifying-variable-locations-in-ir
The inliner requires two additions:
fixupAssignments - Update inlined instructions' DIAssignID metadata so that
inlined DIAssignID attachments are unique to the inlined instance.
trackInlinedStores - Treat inlined stores to caller-local variables
(i.e. callee stores to argument pointers that point to the caller's allocas) as
assignments. Track them using trackAssignments, which is the same method as is
used by the AssignmentTrackingPass. This means that we're able to detect stale
memory locations due to DSE after inlining. Because the stores are only tracked
_after_ inlining, any DSE or movement of stores _before_ inlining will not be
accounted for. This is an accepted limitation mentioned in the RFC.
One change is also required:
Update CloneBlock to preserve debug use-before-defs. Otherwise the assignments
will be dropped due to having the intrinsic operands replaced with empty
metadata (see use-before-def.ll in this patch and this related discourse post.
