The fix in f9ea85611faca82c7494449ddb8bcb1ef1d194cb didn't consider
that the tested register could be aliased.

|
Apply type optimizations across local function calls
|
|
This commit lets the type optimization pass work across functions,
tracking return and argument types to eliminate redundant tests.
|
|
This serves as a base for the upcoming module-level type
optimization, but may come in handy for other passes like
beam_ssa_funs and beam_ssa_bsm that have their own ad-hoc
implementations.

Use lists:splitwith/2 instead of lists:partition/2 for splitting out
phi nodes. Since phi nodes are always the first instructions in a
block, the result will be the same, but splitwith/2 is faster.

We want to decrease the size of the outer state tuple, and gain
ease of understanding by better grouping. This is the first step
of creating a hs_env (handshake environment) part of the state.
This change will be performed gradually to reduce merge conflicts
complexity and risk of introducing errors.

* raimo/stdlib/gen_statem-optimization/OTP-15452:
correct: Work around a compiler mis-optimization
|
|
This was not a compiler optimization that misfired, rather that
the code neede separate case clauses for when the timer was
running and not, so to not call erlang:cancel_timer/1 nor
maps:remove/2 in the case clause where only
a map update was needed before recursion.

A switch is equivalent to a series of '=:=', so we have to subtract
each value individually from the type. Subtracting a join risks
removing too much type information, and managed to narrow "number"
into "float" in the attached test case.

Running ssa_opt_tuple_size early will give more opportunities
for optimizations.
|
|
fd682dd3b1dc corrected label generation for 'or', but forgot to
remove the old incorrect clause (that can no longer be reached).
|
|
The code will be significantly improved by running the
type optimization pass twice.
The ssa_opt_misc pass can be eliminated because everything it does
is also done by the type optimization pass.
|
|
Needed because of the optimizations in 48f20bd589fa69.

|
|
|
|
The common subexpression optimization accidentally caused
unnecessary spilling of live registers. A rather ugly
workaround can be found in loop_timeouts_cancel.
