Optimize away 'not' in sys_core_fold instead of in beam_block
and beam_dead, as we can do a better job in sys_core_fold.
I modified the test suite temporarily to never turn off Core Erlang
modifications and looked at the coverage. With the new optimizations
active in sys_core_fold, the code in beam_block and beam_dead did not
find a single 'not' that it could optimize. That proves that the new
optimization is at least as good as the old one. Manually, I could
also verify that the new optimization would optimize some variations
of 'not' that the old one would not handle.

|
More aggressive optimizations that we plan to introduce could cause
spurious compiler warnings.
|
|
The 'try' ... 'catch' is problematic. Firstly, if no optimization
is possible, an exception will always be thrown. Secondly, bugs
in the code will go unnoticed.
|
|
'=:=' is a cheaper operation than '==', so we should always
use '=:=' if the result will be the same as if '==' were used.
|
|
|
|
Make sure that we take extract all possible type information when
optimizing a 'let' construct.
Since the stronger optimization may generate false warnings, we also
need to take special care to suppress false warnings.

* bjorn/compiler/maps:
v3_codegen: Teach the put_map_* instructions to reuse source registers
beam_validator: Tighten tests of maps
v3_core: Eliminate the sloppiness-encouraging get_ianno/1 function
v3_core: Add is_map tests before map instructions
beam_type: Use the complete register map when calculating liveness
Introduce '%live' annotations with a complete register map
beam_validator: Teach bif_type/3 and is_bif_safe/2 about is_map/1
v3_core: Simplify conversion of map patterns
|
|
The put_map_assoc and put_map_exact instructions in the run-time
system will support that the target register is the same as one of
the source registers. Teach the code generator to take advantage
of that.
The disadvantages of not reusing register when possible is that the
garbage collector may retain dead terms longer than necessary.

get_ianno/1 would retrieve either a bare annotation or an
annotation wrapped in an #a{} record. In both cases, it would
return a wrapped annotation.
We can replace the calls to get_ianno/1 with calls to get_anno/1,
because the argument is always an #iclause{} and all iclause records
are always initialized with a wrapped annotation.
|
|
If we have a sequence of put_map_* instructions operating on the
same map, it will be more efficient if we can have one is_map/2
instruction before put_map_* instructions, so that each put_map_*
does not need to test whether the argument is a map.
|
|
When calculating the number of live registers for allocation
instruction, it is not always safe to start with the number of live
registers at the start of the block. We will need to use the register
map to know whether there are any holes (dead registers) that are not
subsequently filled.
If the allocation instruction already has a number of live registers
calculated, there is nothing to be gained by raising it.
|
|
As a preparation for fixing a bug, introduce a complete register
map in the '%live' annotations.

The decode of an incoming request in a non-relay application results in
a deep list of diameter_avp records. Encoding such a list resulted in a
function_clause error in diameter_codec:pack_avp/1, which expected a
flat list. The list is only flat in the relay case, or in the absence of
AVPs of type Grouped.
This is also related to code that exists but isn't documented. It's
documented that a diameter_app(3) handle_request callback can return
{relay, Opts} to relay a request received in the relay application.
What's not documented is that it can also return {proxy|resend, Opts} in
a non-relay application, but this leads to encode failure when there are
Grouped AVPs. This shouldn't be interpreted as meaning that proxy|resend
are now supported: they aren't. The two extra terms are a historical
relic that should probably be removed. Neither are generally usable
since, for example, a proxy agent may want to modify a request before
resending it. A specific handle_request return is not needed to
implement a proxy agent. Even {relay, Opts} isn't strictly necessary.

The decode of a Grouped AVP ignored the case that extracting component
AVPs with diameter_codec:collect_avps/1 returned a tuple, in the case of
a truncated AVP header.
