* john/erts/OTP-18.3.4/minusminus_trapping/OTP-15371:
Optimize operator '--' and yield on large inputs
|
|
The removal set now uses a red-black tree instead of an array on
large inputs, decreasing runtime complexity from `n*n` to
`n*log(n)`. It will also exit early when there are no more items
left in the removal set, drastically improving performance and
memory use when the items to be removed are present near the head
of the list.
This got a lot more complicated than before as the overhead of
always using a red-black tree was unacceptable when either of the
inputs were small, but this compromise has okay-to-decent
performance regardless of input size.

such as a sub-binary, of a correct utf8 string,

The state without pruned registers was passed on to test_heap
causing the validator to belive registers that aren't live
actually are live.

Wrong result for
(X bsl WS) bxor Y.
where
X is any negative integer
Y is any integer that does not require more words than X
WS is erlang:system_info(wordsize) or larger
Fix: The subtraction of 1 (for 2-complement conversion)
must be carried along all the way to the last words.
|
|
The effect of the race is that a pre-allocated memory block
is inserted last without updating tail.data.last, which will cause
all subsequent insertions to also fail to update tail.data.last.
Hence all pre-allocation for this quick alloc instance is leaked
for this thread and will fallback on erts_alloc.
