beam_ssa_type: Propagate the 'none' type from calls
|
|
Consider this pseudo code:
f(...) ->
Val = case Expr of
... ->
... ;
... ->
... ;
... ->
my_abort(something_went_wrong)
end,
%% Here follows code that uses Val.
.
.
.
my_abort(Reason) ->
throw({error,Reason}).
The first two clauses in the case will probably provide some
information about the type of the variable `Var`, information
that would be useful for optimizing the code that follows the
case.
However, the third clause would ruin everything. The call
to `my_abort/1` could return anything, and thus `Val` could
also have any type.
294d66a295f6 introduced module-level type analysis, which will in
general keep track of the return type of a local function
call. However, it does not improve the optimization for this specific
function. When a function never returns, that is, when its type is
`none`, it does not propagate the `none` type, but instead pretends
that the return type is `any`.
This commit extends the handling of functions that don't return to
properly handle the `none` type. Any instructions that directly
follows the function that does not return will be discarded, and the
call will be rewritten to a tail-recursive call.
For this specific example, it means that the type for `Val` deduced
from the first two clauses will be retained and can be used for
optimizing the code after the case.

The ssa_opt_sink optimization of beam_ssa_opt could get very slow
for certain huge functions. 9a190cae9bd7 partly addressed this issue
by terminating the optimization early if there happened to be no
get_tuple_element instructions at all in the function.
This commit addresses the issue more directly by making the dominator
calculation in beam_ssa:dominators/1 more efficient. The same
algorithm as before is used, but it is implemented in a more efficient
way based on the ideas in "A Simple, Fast Dominance Algorithm"
(http://www.hipersoft.rice.edu/grads/publications/dom14.pdf).
As well as being more efficient, the new implementation also gives
an explicit representation of the dominator tree, which makes it
possible to simplify and optimize the ssa_opt_sink optimization.

You previously had to initialize ei via erl_init() which
implied that you were forced to link against the erl_interface
even when not using it (besides initializing ei).

Prior to 294d66a295f6c2101fe3c2da630979ad4e736c08 there wasn't much
point to keeping track of tuple element types; they were only known
when we had inserted or extracted values from a tuple, and in
neither case was it likely that we'd extract the same values again.
It makes a lot more sense to do so now that type optimizations are
applied across functions; if we return a tuple it's very likely
that its elements will be extracted soon after, and knowing their
types lets us eliminate more type checks.

Reduce compilation times

Adds two hash functions blake2b and blake2s (64 bit hash and 32 bit hash
respectively). These are modern and standard hash functions used in
blockchains and encrypted communication protocols (e.g. Noise -
http://www.noiseprotocol.org/). The hash functions are available in
OpenSSL since version 1.1.1.
Also add test cases and mention in documentation.

Fix typo in erlang.xml

A long time ago there was a good idea to run compiled code in a
slave node. Nowadays, not so much.
|
|
test_lib:is_cloned_mod(inline_SUITE) would return true.
|
|
There could be a warning with a `no_file` atom instead of filename
and line number.
