* Improve SSA DF computation memory usage

DF(b) can be stored in a vector instead of a hashtable (set). Nothing needs a O(1) membership test, the duplicates that may be generated during DF construction can be easily avoided by observing that:
* each block in the graph is processed exactly once
* during processing the block is added to the relevant DF vectors, at the end of each vector. If the same DF vector is encountered multiple times then checking if the block is already a member is trivial.

* Use the same block BitVec for topo sort and IDom

* Add BitVecOps::TryAddElemD

Makes the code more readable and avoids the duplicated IsShort test that a separate IsMember/AddElemD may generate.

* Improve SSA IDF computation memory usage

Like DF(b), IDF(b) can be stored in a vector if duplicates are avoided. This can be done by using a BitVector like TopologicalSort and ComputeImmediateDom already do. It's cheaper than using a hashtable (even though it requires a "clear" for every block that has a frontier).

Also, storing IDF(b) into a vector makes it easier to track newly added blocks - they're at the end of the vector. Using a separate "delta" set is no longer needed.

6 years agoJIT: look through GT_RET_EXPR when forming inline candidates
Andy Ayers [Fri, 10 Nov 2017 01:07:12 +0000 (17:07 -0800)]
JIT: look through GT_RET_EXPR when forming inline candidates

If an inline candidate has args that come from calls that are inline
candidates, the arg trees for the candidate may be GT_RET_EXPRs. Since
the jit inlines in preorder, any arg inlines will have been resolved
by the time we get to the candidate. So, the jit can look back through
the GT_RET_EXPR to get a better handle on the actual arg tree.

Doing this has several small benefits:
* It short-circuits parts of the subsequent GT_RET_EXPR update and so
saves a little bit of throughput.
* It potentially allows for more streamlined arg passing since the actual
node side effects may be less constraining than the placeholder effects on
the GT_RET_EXPR (which must be "worst case").
* It may unblock inlines as actual arg values can be seen when evaluating
the candidate for profitability.

During testing I found cases where looking at the actual arg seemed to
degrade information. This turned out to be a misuse of `argHasLdargaOp`
to indicate that a caller-supplied argument was potentially locally
aliased.

This misuse was blocking type propagation when the actual arg tree was seen to
be an aliasable local reference instead of the formerly opaque GT_RET_EXPR.
To fix this, I split out the aliased arg case with a different flag. All
that the jit needs to ensure in the aliased case is that it does not directly
substitute the arg; the arg must be evaluated at the point of the call. The
type of the actual can safely propagate to the arg as long as the arg itself
is not modifiable.

Added a utility for walking back through GT_RET_EXPRs and updated the
other case where the jit was doing this to use the utility as well.

Closes #14174.
