2015-09-09dialyzer: Correct the handling of parameters of opaque typesHans Bolinder
Prior to this commit, the fact that parameters of opaque types are expanded differently depending on the current values of limits used during expansion, caused problems later when the types of parameters are used for determining if opaque types are comparable.

2015-09-07proc_lib: Add format/3Björn Gustavsson
We'll need a way to limit the size of the crash report produced by proc_lib:format(). Add format/3, where the third argument is a depth argument.

2015-09-07Remove unused code in error logger handlersBjörn Gustavsson
A long time ago, errors from the emulator itself was sent as messages that would end up in the handle_info/2 function. Those clauses in handle_info/2 can be removed. The code for handling events tagged 'info' instead of 'info_msg' can also be taken out.

2015-09-07sasl_SUITE: Add a rudimentary test of the utc_log configurationBjörn Gustavsson
2015-09-07sasl_SUITE: Correct the log_file/1 test caseBjörn Gustavsson
The test case did not test the log files were created. And they were not created, because filelib:ensure_dir/1 was used incorrectly.
2015-09-07proc_lib_SUITE: Remove added report handlersBjörn Gustavsson
Report handlers are not automatically removed. That means that the report handler will remain installed until the entire running of the stdlib test suite finishes. That could potentially cause problems.
2015-09-07zip_SUITE: Don't trust priv_dir to be emptyBjörn Gustavsson
The unzip_to_binary/1 and zip_to_binary/1 test cases need the test_server's priv_dir to be empty. On Windows, file system pecularities can prevent us from emptying priv_dir. Since the point of this test case is not to test file operations on Windows, simplify things by working in a newly created sub directory of priv_dir.
2015-09-04compiler: Fix get_map_elements register corruptionBjörn-Egil Dahlberg
Instruction get_map_elements might destroy target registers when the fail-label is taken. Only seen for patterns with two, and only two, target registers. Specifically: we copy one register, and then jump. foo(A,#{a := V1, b := V2}) -> ... foo(A,#{b := V}) -> ... call foo(value, #{a=>whops, c=>42}). corresponding assembler: {test,is_map,{f,5},[{x,1}]}. {get_map_elements,{f,7},{x,1},{list,[{atom,a},{x,1},{atom,b},{x,2}]}}. %% if 'a' exists but not 'b' {x,1} is overwritten, jump {f,7} {move,{integer,1},{x,0}}. {call_only,3,{f,10}}. {label,7}. {get_map_elements,{f,8},{x,1},{list,[{atom,b},{x,2}]}}. %% {x,1} (src) is read with a corrupt value {move,{x,0},{x,1}}. {move,{integer,2},{x,0}}. {call_only,3,{f,10}}. The fix is to remove 'opt_moves' pass for get_map_elements instruction in the case of two or more destinations. Reported-by: Valery Tikhonov

* sverk/hipe-fix-literal-crc: erts,hipe,dialyzer: Fix hipe checkum of target runtime system erts: Change THE_NON_VALUE to not be hard coded in hipe compiler OTP-12962 OTP-12963 OTP-12964
2015-08-31erts,hipe,dialyzer: Fix hipe checkum of target runtime systemSverker Eriksson
Main problem: A faulty HIPE_LITERAL_CRC was not detected by the loader. Strangeness #1: Dialyzer should ask the hipe compiler about the target checksum, not an internal bif. Strangeness #2: The HIPE_SYSTEM_CRC checksum was based on the HIPE_LITERALS_CRC checksum. Solution: New HIPE_ERTS_CHECKSUM which is an bxor of the two (now independent) HIPE_LITERALS_CRC and HIPE_SYSTEM_CRC. HIPE_LITERALS_CRC represents values that are assumed to stay constant for different VM configurations of the same arch, and are therefor hard coded into the hipe compiler. HIPE_SYSTEM_CRC represents values that may differ between VM variants. By default the hipe compiler asks the running VM for this checksum, in order to create beam files for the same running VM. The hipe compiler can be configured (with "make XCOMP=yes ...") to create beam files for another VM variant, in which case HIPE_SYSTEM_CRC is also hard coded. ToDo: Treat all erts properties the same. Either ask the running VM or hard coded into hipe (if XCOMP=yes). This will simplify and reduce the risk of dangerous mismatches. One concern might be the added overhead from more frequent calls to hipe_bifs:get_rts_param.

2015-08-24erts: Change THE_NON_VALUE to not be hard coded in hipe compilerSverker Eriksson
Instead ask running VM for the value of THE_NON_VALUE, which is different between opt and debug VM. Same hipe compiler can now compile for both opt and debug VM.

2015-08-24Optimize zip:unzip/2 when uncompressing to memoryDan Gudmundsson
Optimize the case where we are appending to the end of the binary, use binary syntax to create binaries with room for expansion in the next loop, instead of using iolist_to_binary which creates a binary of the exact size and needs to be copied in each loop. Also remove support the unused Acc as iolists.
