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

2015-06-17compiler: Add regressions_SUITEBjörn-Egil Dahlberg
regressions_SUITE will have code snippets which previously crashed the compiler. This commits includes a test for Maps crash in beam_bool.
2015-06-17compiler: Fix beam_bool pass for get_map_elementsBjörn-Egil Dahlberg
Before beam_split the get_map_elements instruction is still in blocks and the helper function in beam_jump did not reflect this. Reported-by: Quviq twitter account

2015-05-22sys_core_fold: Eliminate warnings for unused terms in effect contextBjörn Gustavsson
The optimization introduced in 0a0d39d351fc could cause spurious warnings of the type: "a term is constructed, but never used". That would happen for constructs in effect context. To avoid those warnings, we will need to apply warning suppression also in effect context.

2015-05-21Don't make 'compiler' dependent on 'tools'Björn Gustavsson
In a5d724cf240a, a debug option for running eprof on a specific compiler pass was added. That commit added a direct call to the eprof module in the tools application, and therefore the test case otp_SUITE:runtime_dependencies/1 would fail because xref would find a call to the tools application, but tools is not listed as a runtime dependency in compiler.app. Since the 'eprof' option is only likely to be used by compiler maintainers, we don't want a real dependency to the tools application. Therefore, use c:appcall/4 to hide the call to the eprof module (and to report the error nicely if the tools application is missing).

2015-05-21compiler: Teach beam_bsm get_map_elements instructionBjörn-Egil Dahlberg

2015-05-13sys_core_fold: Eliminate warnings for unused termsBjörn Gustavsson
The optimization introduced in 0a0d39d351fc would cause spurious warnings of the type: "a term is constructed, but never used". To avoid the warning, we must mark not only tuples and lists as compiler_generated, but also each element. We must also propagate compiler_generated annotations in lets. For example, if we have: let <X -| ['compiler_generated']> = 42 in X + 1 we must propagate the compiler_generated annotation to the literal when do constant propagation: 42 -| ['compiler_generated'] + 1
