History

Adam Nemet abdb6ed3d0 [LAA, LV] Port to new streaming interface for opt remarks. Update LV

(Recommit after making sure IsVerbose gets properly initialized in
DiagnosticInfoOptimizationBase.  See previous commit that takes care of
this.)

OptimizationRemarkAnalysis directly takes the role of the report that is
generated by LAA.

Then we need the magic to be able to turn an LAA remark into an LV
remark.  This is done via a new OptimizationRemark ctor.

Analysis Opportunities:

//===---------------------------------------------------------------------===//

In test/Transforms/LoopStrengthReduce/quadradic-exit-value.ll, the
ScalarEvolution expression for %r is this:

  {1,+,3,+,2}<loop>

Outside the loop, this could be evaluated simply as (%n * %n), however
ScalarEvolution currently evaluates it as

  (-2 + (2 * (trunc i65 (((zext i64 (-2 + %n) to i65) * (zext i64 (-1 + %n) to i65)) /u 2) to i64)) + (3 * %n))

In addition to being much more complicated, it involves i65 arithmetic,
which is very inefficient when expanded into code.

//===---------------------------------------------------------------------===//

In formatValue in test/CodeGen/X86/lsr-delayed-fold.ll,

ScalarEvolution is forming this expression:

((trunc i64 (-1 * %arg5) to i32) + (trunc i64 %arg5 to i32) + (-1 * (trunc i64 undef to i32)))

This could be folded to

(-1 * (trunc i64 undef to i32))
