2015-10-05beam_reorder: Eliminate compiler crashBjörn Gustavsson
c288ab87 added beam_reorder to move get_tuple_element instructions. Compiling code such as the following would crash the compiler: alloc(_U1, _U2, R) -> V = R#alloc.version, Res = id(V), _ = id(0), Res. The crash would occur because the following two instructions: {get_tuple_element,{x,2},1,{x,1}}. {allocate_zero,1,2}. were swapped and rewritten to: {allocate_zero,1,1}. {get_tuple_element,{x,2},1,{x,1}}. That transformation is not safe because the allocate_zero instruction would kill {x,2}, which is the register that is holding the reference to the tuple. Only do the transformation when the tuple reference is in an x register with a lower number than the destination register.
2015-09-28beam_type: Improve optimization by keeping track of integersBjörn Gustavsson
The ASN.1 compiler often generates code similar to: f(<<0:1,...>>) -> ...; f(<<1:1,...>>) -> .... Internally that will be rewritten to (conceptually): f(<<B:1,Tail/binary>>) -> case B of 0 -> case Tail of ... end; 1 -> case Tail of ... end; _ -> error(case_clause) end. Since B comes from a bit field of one bit, we know that the only possible values are 0 and 1. Therefore the error clause can be eliminated like this: f(<<B:1,Tail/binary>>) -> case B of 0 -> case Tail of ... end; _ -> case Tail of ... end end. Similarly, we can also a deduce the range for an integer from a 'band' operation with a literal integer. While we are at it, also add a test case to improve the coverage.
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.
2015-04-22Add z_SUITE to validate loaded codeBjörn Gustavsson
If we want to have test cases that run eprof, we must make sure that there are no modules loaded that don't have a working module_info/1 function, since eprof calls module_info(functions) to retrieve the list of functions in the module. Some test cases load modules compiled from Core Erlang that don't have any module_info/1 functions, so we will need make sure that all such modules have been unloaded. Add z_SUITE:loaded/1 to run after all other test cases to verify that all modules that the code server consider loaded are indeed loaded and all have working module_info/0,1 functions.
2015-04-22test suite: Always place .core files in data directoriesBjörn Gustavsson
For tidiness, always place .core files in data directories.

2014-02-21compiler: Fix map inliningBjörn-Egil Dahlberg
Added coverage of operating map variable.

2013-01-18Remove support for parameterized modulesBjörn Gustavsson
2012-10-23Correct typo in test suite nameBjörn Gustavsson
It should be beam_except_SUITE, since it tests the beam_except module (introduced in 726f6e4c7afe8ce37b30eedbebe583e7b9bfc51b).

2012-01-04Remove part_eval_SUITEBjörn Gustavsson
This test suite has been superseded by other test suites (e.g. guard_SUITE). Removing it does not decrease the coverage.
2012-01-04Add the beam_except pass to optimize exceptionsBjörn Gustavsson
In order to save space, rewrite suitable calls to erlang:error/{1,2} to special BEAM instructions. This code is probably longer than the code taken out of v3_life and v3_codegen in the previous commit, but it is much easier to understand and maintain since the BEAM assembler format is better understood than the v3_life format.
2011-09-21beam_disasm: Handle stripped BEAM filesHaitao Li
beam_disasm:file/1 would crash if asked to disassemble a stripped BEAM file without an "Attr" chunk.

2010-11-15Call chmod without the "-f" flagHolger Weiß
"-f" is a non-standard chmod option which at least SGI IRIX and HP UX do not support. As the only effect of the "-f" flag is to suppress warning messages, it can be safely omitted.
2010-03-26compiler tests: Compile a few more modules with 'inline'Björn Gustavsson
Since a function_clause exception in an inlined function will be changed to a case_clause exception, we must test for both.
2010-03-26compiler tests: Test the 'inline' option betterBjörn Gustavsson
Clone some test suites and compile them with the 'inline' option to test inlining more thorughly.
2010-03-22compiler: Don't support the r11 optionBjörn Gustavsson
The r11 option was used to generate BEAM modules that could loaded both on both R11 and R12/R13 to facilitate testing that R11 and R13 nodes could communicate with each other. Since R14 is only required to be compatible with R12 and R13 nodes, the r11 option is no longer needed.
