2015-03-09Update type information based on BIFs that returns integersBjörn Gustavsson
2015-03-09sys_core_fold: Strengthen type optimization in letsBjörn Gustavsson
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.

2015-03-09v3_codegen: Teach the put_map_* instructions to reuse source registersBjörn Gustavsson
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.
2015-03-09beam_validator: Tighten tests of mapsBjörn Gustavsson
2015-03-09v3_core: Eliminate the sloppiness-encouraging get_ianno/1 functionBjörn Gustavsson
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.
2015-03-09v3_core: Add is_map tests before map instructionsBjörn Gustavsson
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.
2015-03-09beam_type: Use the complete register map when calculating livenessBjörn Gustavsson
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.
2015-03-09Introduce '%live' annotations with a complete register mapBjörn Gustavsson
As a preparation for fixing a bug, introduce a complete register map in the '%live' annotations.

2015-03-04Allow encode of decoded diameter_avp listAnders Svensson
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.

2015-03-04Fix handling of length errors on Grouped AVPsAnders Svensson
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.
