code:add_pathsa/1 reverts the list of directories when adding it at the beginning of the code path. The command line option '-pa' behaves in the same way. This is now documented.

2016-09-26sys_core_fold: Run optimizations to a fixpointBjörn Gustavsson
Run the optimizations until a fixpoint is reached, or until the maximum iteration count is reached. The hope is that in the future we can many small optimizations instead of optimizations that try to do everything in one pass. This change allows us to remove the ad-hoc calls to expr/2 to run more optimizations on a piece of code.
2016-09-26sys_core_fold: Improve case optimizationBjörn Gustavsson
The optimization that avoids building a tuple in a case expression would not work if any clause matched a tuple as in the following example: f(A, B) -> case {A,B} of {<<X>>,Y} -> {X,Y} end. The generated Core Erlang code would look like this (note the tuples in the case expression and the pattern): 'f'/2 = fun (_cor1,_cor0) -> case {_cor1,_cor0} of <{#{#<X>(8,1,'integer',['unsigned'|['big']])}#,Y}> when 'true' -> {X,Y} . . . end It is expected that the code should look like this (note that tuples have been replaced with "values"): 'f'/2 = fun (_cor1,_cor0) -> %% Line 5 case <_cor1,_cor0> of <#{#<X>(8,1,'integer',['unsigned'|['big']])}#,Y> -> {X,Y} . . . end While at it, also fix bugs in the handling of pattern with aliases. The bindings were produced in the wrong order (creating 'let's with referring to free variables), but in most cases the incorrect bindings were discarded later without causing any harm.
2016-09-26sys_core_fold: Correct scope verification codeBjörn Gustavsson
703e8f4490bf broke the scope verification code (by calling ordsets:is_subset/2 with an unsorted second argument). While we are it, also optimize the verification function by avoiding converting the map to a sorted list.
2016-09-26core_pp: Correct printing of map updatesBjörn Gustavsson
2016-09-24Let file:write_file/3 use writevNathan Long
Previously, this function would turn any input into a single binary before writing. This meant it could not take advantage of the `writev` system call if it was given a list of binaries and told to write with `raw` mode. To see this, start an erlang shell on the parent commit, and also start this dtrace script: https://github.com/evanmiller/tracewrite like this: sudo dtrace -s tracewrite.d -p $(pgrep beam) In the erlang shell, run the following: file:write_file("/tmp/tmp.txt", [<<97,98>>, <<98,97>>], [raw]). In the dtrace output, you will see that the system call used is `write`. Now repeat with this commit, and you will see that `writev` is used.

2016-09-23[ttb] Add option <c>queue_size</c> to tracer/2Siri Hansen
This sets the maximum queue size for the IP trace driver which is used when tracing to shell and/or <c>{local,File}</c>. Also, change the default queue size set by dbg:trace_port/2 to 200.

2016-09-22file_SUITE: Test file:write_file/3Björn Gustavsson
Extend file_SUITE:read_write_file/1 to test file:write_file/3 which was not tested at all. While we are it, remove the superfluous roundtrips tests of term_to_binary/1 and binary_to_term/1. Those BIFs are tested in detail in other test suites (for example, binary_SUITE in emulator_test).

2016-09-21Simplify handling of internal BIFsBjörn Gustavsson
Do a simpler translation of internal BIFs. While we are it, also remove the dummy values of Index and Uniq from the make_fun internal operation.
2016-09-21v3_life: Eliminate special handling of guardsBjörn Gustavsson
Remove the special handling #k_try{} in guards in v3_life. If we introduce a new #k_protected{} record in v3_kernel, v3_life no longer needs to know whether it is processing guards or bodies.
2016-09-21Simplify beam_utilsBjörn Gustavsson
When beam_utils was first written, it did not have the functions for testing whether a register was not used. Those were added later, in sort of a hacky way. Also, is_killed*() and is_not_used*() for Y registers would return the same answer. Fix that to make the API more consistent (an Y register can only be killed by a deallocate/1 instruction). We will need to change beam_trim to call beam_utils:is_not_used/3 instead of beam_utils:is_killed/3.
2016-09-21bs_match_SUITE: Add a test case for beam_utilsBjörn Gustavsson
During development, a bug in beam_utils caused a compiler failure in xmerl. If the bug reappears, make sure that we catch it when compiling the compiler test suite.
2016-09-21bif_SUITE: Cover the remaining uncovered linesBjörn Gustavsson
2016-09-21erl_bifs: Remove error_logger:warning_map/0 as a safe BIFBjörn Gustavsson
There is no need to list every obscure safe BIF in erl_bifs:is_safe/3. The purpose of erl_bifs:is_safe/3 is merely to warn when the return value of one of the safe BIFs is ignored.
2016-09-21beam_validator: Correct reporting of y register numberBjörn Gustavsson
The error would be: {multiple_match_contexts,[{x,0},2]} instead of: {multiple_match_contexts,[{x,0},{y,2}]}
2016-09-21beam_jump: Don't try to handle a label at the very endBjörn Gustavsson
Since the beam_a pass has always been run and have removed any unused label, there can never be a label as the very last instruction in a function.
2016-09-21beam_jump: Simplify eliminate_fallthroughs/2Björn Gustavsson
eliminate_fallthroughs/2 has special code to handle two labels next to each other, but that does not seem to ever happen and there was one line uncovered in is_label/1. Since inserting an extra jump between two labels would not cause any real problems, remove the extra handling of two consecutive labels.
2016-09-21beam_listing: Remove support for listing sys_pre_expand formatBjörn Gustavsson
The compiler stopped using sys_pre_expand in ae3e177c514c354831.
