2017-01-12Add specs for the beam_*:module/2 functionsBjörn Gustavsson
2016-10-05beam_block: Avoid unsafe inclusion of get_map_elements in blocksBjörn Gustavsson
c2035ebb8b restricted the get_map_elements instruction so that it could only occur at the beginning of a block. It turns out that including it anywhere in a block is unsafe. Therefore, never put get_map_elements instruction in blocks. (Also remove the beam_utils:join_even/2 function since it is no longer used.) ERL-266

2016-04-08Remove unreachable code after 'raise' instructionsBjörn Gustavsson
Remove the unreachable instructions after a 'raise' instruction (e.g. a 'jump' or 'deallocate', 'return') to decrease code size.

2015-08-21Put 'try' in blocks to optimize allocation instructionsBjörn Gustavsson
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.

2015-01-12compiler: Rename util function to adhere to name policyBjörn-Egil Dahlberg
* beam_utils:joineven/1 -> beam_utils:join_even/1 * beam_utils:split_even/1 -> beam_utils:split_even/1
2015-01-09compiler: Remove unnecassary guard for get_map_elementsBjörn-Egil Dahlberg
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.
2014-08-26compiler: Use variables in Map beam assmeblerBjörn-Egil Dahlberg
2014-02-13compiler: Change map instructions for fetching valuesBjörn-Egil Dahlberg
* Combine multiple get values with one instruction * Combine multiple check keys with one instruction
2014-01-28compiler: Implement different instructions for => and :=Björn Gustavsson
2014-01-28Implement support for maps in the compilerBjörn Gustavsson
To make it possible to build the entire OTP system, also define dummys for the instructions in ops.tab.
2011-12-06Teach the compiler the 'no_dead' optionBjörn Gustavsson
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.
