* henrik/update-copyrightyear:
update copyright-year
|
|
Remove the unreachable instructions after a 'raise' instruction
(e.g. a 'jump' or 'deallocate', 'return') to decrease code size.
|
|
|
|
Put 'try' instructions inside block to improve the optimization
of allocation instructions. Currently, the compiler only looks
at initialization of y registers inside blocks when determining
which y registers that will be "naturally" initialized.

* beam_utils:joineven/1 -> beam_utils:join_even/1
* beam_utils:split_even/1 -> beam_utils:split_even/1
|
|
No need to check for fail label zero for get_map_elements in beam_split.
get_map_elements is always used in pattern matching and never in a body.

|
|
* Combine multiple get values with one instruction
* Combine multiple check keys with one instruction
|

|
|
To make it possible to build the entire OTP system, also define
dummys for the instructions in ops.tab.
|
|
To facilitate debugging of compiler bugs, teach the compiler the
'no_dead' option. Since the beam_dead pass used to do the necessary
splitting of basic blocks to expose all labels, we must move that
splitting into a separate pass that is always run.
