LoadBB:
v1 = load %addr

PredBB:

SuccBB:
v2 = load %addr

Instruction v1 in LoadBB is partially redundant, edge (PredBB, LoadBB) is a
critical edge. SuccBB is another successor of PredBB, it contains another load
v2 which is identical to v1. Current GVN splits the critical edge
(PredBB, LoadBB) and inserts a new load in it. A better method is move the load
of v2 into PredBB, then v1 can be changed to a PHI instruction.
If there are two or more similar predecessors, like the test case in the bug
entry, current GVN simply gives up because otherwise it needs to split multiple
critical edges. But we can move all loads in successor blocks into predecessors.

[BOLT] stale profile matching [part 1 out of 2]
BOLT often has to deal with profiles collected on binaries built from several
revisions behind release. As a result, a certain percentage of functions is
considered stale and not optimized. This diff adds an ability to match profile
to functions that are not 100% binary identical, which increases the
optimization coverage and boosts the performance of applications.
The algorithm consists of two phases: matching and inference:
- At the matching phase, we try to "guess" as many block and jump counts from
the stale profile as possible. To this end, the content of each basic block
is hashed and stored in the (yaml) profile. When BOLT optimizes a binary,
it computes block hashes and identifies the corresponding entries in the
stale profile. It yields a partial profile for every CFG in the binary.
- At the inference phase, we employ a network flow-based algorithm (profi) to
reconstruct "realistic" block and jump counts from the partial profile
generated at the first stage. In practice, we don't always produce proper
profile data but the majority (e.g., >90%) of CFGs get the correct counts.
This is a first part of the change; the next stacked diff extends the block hashing
and provides perf evaluation numbers.

[InstrProf] Use BalancedPartitioning to order temporal profiling trace data
In [0] we described an algorithm called //BalancedPartitioning// (bp) to consume function traces [1] and compute a function order that reduces the number of page faults during startup.
This patch adds the `order` command to the `llvm-profdata` tool which uses bp to output a function order that can be passed to the linker via `--symbol-ordering-file=`.
Special thanks to Sergey Pupyrev and Julian Mestre for designing this balanced partitioning algorithm.

[mlir][Toy] Remove unnecessary transpose from chapter 1 example
The call to 'multiply_transpose' in the initialization of the variable 'f' was
intended to have a shape mismatch. However the variable 'a' has shape <2, 3> and
the variable 'c' has shape <3, 2>, so the arguments 'transpose(a)' and 'c' have
in fact compatible shapes (<3, 2> both), the opposite of what is wanted here.

[DebugInfo] Add error checking around data extraction in DWARFAbbreviationDeclaration::extract
In trying to hoist errors further up this callstack, I discovered that
if the data in the debug_abbrev section is invalid entirely, the code
that parses the debug_abbrev section may do strange or unpredictable
things. The underlying issue is that DataExtractor will return a value
of 0 when it encounters an error in extracting a LEB128 value. It's thus
difficult to determine if there was an error just by looking at the
return value. This patch aims to bail at the first sight of an error in
the debug_abbrev parsing code.
