2016-09-26core_pp: Correct printing of map updatesBjörn Gustavsson
2016-09-26Use @ in variable names generated by core and kernelJosé Valim
The previous variable names can be generated by projects like LFE and Elixir, leading to possible conflicts. Our first to choice to solve such conflicts was to use $ but that's not a valid variable name in core. Therefore we picked @ which is currently supported and still reduces the chance of conflicts.

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.

2016-09-22file_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).

2016-09-22Fix compilation when OpenSSL doesn't support RC4Andreas Schultz
When OpenSSL has been configured with the "no-rc4" option, the header file rc4.h doesn't exist, and neither does the rc4 functions. Let's handle those by checking whether OPENSSL_NO_RC4 is defined.

2016-09-21ssl: Make sure test has correct inputIngela Anderton Andin
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.

2016-09-19Use more correct delimiters for erl_nif.h includeTuncer Ayaz
Anywhere but the beam sources we shouldn't #include "erl_nif.h", because what "erl_nif.h" does is: (1) fail to find it outside of -I dirs, (2) then treat it as if it was written like <erl_nif.h>. Using <erl_nif.h> skips (1). More information can be found in 6.10.2 of the C standard. Because the examples use "erl_nif.h", NIF projects in the Erlang ecosystem copy this verbatim and make the same mistake.
