OTP-12685
|
|
Seen on SSL application where substraction with x registers were prevalent:
* i_minus specialization on x registers
* i_plus specialization on x registers
|
|
Common pattern seen in SSL:
move y x | move r x -> move2
move r x | move y x -> move2
Common pattern seen in SSL and Compiler:
move x r | move x x -> move2

* i_rem specialization on x registers
|
|
* i_band specialization on x registers and constants
|
|
May lessen load/store latency.

A type error caused the optimization to never kick in.

Move an entire region of x registers to the stack.
This reduces the dispatch pressure of move instructions.
Also introduce a move2 specialization for some common move patterns:
move r y | move x y -> move2 : As above, moving regions to the stack
move x r | move x y -> move2 : A seemingly common pattern
|
|
|
|
* i_is_lt for r, x registers and constants
* i_is_ge for x registers and constants
* i_is_exact_eq for r and x registers

Some examples had encountered the space eater.

fbaa0bec replaced the use of now/0 with erlang:monotonic_time/1 but at
the same time introduced a bug in inPeriod/3 so that it would always
return 'true' (the subtraction Time - Now would always result in
a non-positive number that would always be less than Period).
The symptoms of the bug is that when a child has been restarted the
maximum number of times allowed, the supervisor will terminate,
regardless of how much time that elapses between the restarts.
There was no test case that detected this problem. Add the missing
test case to ensure that this bug stays killed.
