The fix in f9ea85611faca82c7494449ddb8bcb1ef1d194cb didn't consider
that the tested register could be aliased.
|
|
The type annotations inserted by beam_ssa_type and beam_ssa_bsm
would inadvertently disable stack trimming, as unknown instructions
are considered unsafe.

Try to eliminate short blocks that starts with a phi node
and end in a return. For example:
Result = phi { Res1, 4 }, { literal true, 5 }
Ret = put_tuple literal ok, Result
ret Ret
The code in this block can be inserted at the end blocks 4 and
5. Thus, the following code can be inserted into block 4:
Ret:1 = put_tuple literal ok, Res1
ret Ret:1
And the following code into block 5:
Ret:2 = put_tuple literal ok, literal true
ret Ret:2
Which can be further simplified to:
ret literal {ok, true}
This transformation may lead to more code improvements, for example:
* Stack trimming
* Fewer test_heap instructions
* Smaller stack frames

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.

Consider this function and its corresponding BEAM code:
foo(Map, Key) ->
Val = case Map of
#{Key:=Val0} -> Val0;
_ -> default
end,
bar(1, 2, Val).
{label,2}.
{test,is_map,{f,3},[{x,0}]}.
{get_map_elements,{f,3},{x,0},{list,[{x,1},{x,0}]}}.
^^^^^
{jump,{f,4}}.
{label,3}.
{move,{atom,default},{x,0}}.
^^^^^
{label,4}.
{move,{integer,2},{x,1}}.
{move,{x,0},{x,2}}.
^^^^^
{move,{integer,1},{x,0}}.
{call_only,3,{f,6}}.
Note that the value of the variable `Val` will first be
placed in `{x,0}` and then moved to `{x,2}` where it needs
to be when calling the `bar/3` function.
The reason for the extra `move` instruction is that the
register allocator picks the lowest numbered available register
when choosing a register to put a variable in. In this case,
`{x,0}` will be chosen.
If we only could give a hint to the register allocator that
it would be better to put `Val` in `{x,2}`, the extra `move`
would disappear:
{label,2}.
{test,is_map,{f,3},[{x,0}]}.
{get_map_elements,{f,3},{x,0},{list,[{x,1},{x,2}]}}.
{jump,{f,4}}.
{label,3}.
{move,{atom,default},{x,2}}.
{label,4}.
{move,{integer,2},{x,1}}.
{move,{integer,1},{x,0}}.
{call_only,3,{f,6}}.
There already is an existing sub pass (`reserve_regs`) in
`beam_ssa_pre_codegen` that among things tries to give the register
allocator hints that some variables should be placed in specific
registers, if possible. However, the existing hinting mechanism is
limited, essentially only working within a single SSA block.
This commit extends the hinting mechanism, allowing hints to be passed
across SSA blocks, eliminating `move` instructions and register
shuffling in many places. (494 modules out of a sample of 1236 modules
were changed by this commit.)

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.
