2017-04-25Store abstract code in the Dbgi chunkJosé Valim
The new Dbgi chunk returns data in the following format: {debug_info_v1, Backend, Data} This allows compilers to store the debug info in different formats. In order to retrieve a particular format, for instance, Erlang Abstract Format, one may invoke: Backend:debug_info(erlang_v1, Module, Data, Opts) Besides introducing the chunk above, this commit also: * Changes beam_lib:chunk(Beam, [:abstract_code]) to read from the new Dbgi chunk while keeping backwards compatibility with old .beams * Adds the {debug_info, {Backend, Data}} option to compile:file/2 and friends that are stored in the Dbgi chunk. This allows the debug info encryption mechanism to work across compilers * Improves dialyzer to work directly on Core Erlang, allowing languages that do not have the Erlang Abstract Format to be dialyzer as long as they emit the new chunk and their backend implementation is available Backwards compatibility is kept across the board except for those calling beam_lib:chunk(Beam, ["Abst"]), as the old chunk is no longer available. Note however the "Abst" chunk has always been optional. Future OTP versions may remove parsing the "Abst" chunk altogether from beam_lib once Erlang 19 and earlier is no longer supported. The current Dialyzer implementation still supports earlier .beam files and such may also be removed in future versions.
2017-04-12Correct compile_SUITE:core_roundtrip/1Björn Gustavsson
The test is supposed to compare the Core Erlang code that has been printed and parsed back. It did compare and print any differences, but it did not fail when there were differences. Also fix problems with variable names and maps not comparing equal when the inliner has been used.
2017-02-12Add extra_chunks option to compileJosé Valim
This allow languages such as Elixir and LFE to attach extra chunks to the .beam file without having to parse the beam file after compilation. This commit also cleans up the interface to beam_asm, allowing chunks to be passed from the compiler without a need to change beam_asm API on every new chunk.
2017-01-30Add new AtU8 beam chunkJosé Valim
The new chunk stores atoms encoded in UTF-8. beam_lib has also been modified to handle the new 'utf8_atoms' attribute while the 'atoms' attribute may be a missing chunk from now on. The binary_to_atom/2 BIF can now encode any utf8 binary with up to 255 characters. The list_to_atom/1 BIF can now accept codepoints higher than 255 with up to 255 characters (thanks to Björn Gustavsson).
2016-12-07Add option 'deterministic' for reproducible buildsBjörn Gustavsson
Add the option 'deterministic' to make it easier to achieve reproducible builds. This option omits the {options,...} and {source,...} tuples in M:module_info(compile), because those options may contain absolute paths. The author of ERL-310 suggested that only compiler options that may contain absolute paths (such as {i,...}) should be excluded. But I find it confusing to keep only some options. Alternatives considered: Always omitting this information. Since this information has been available for a long time, that would probably break some workflows. As an example that some people care about {source,...}, 2d785c07fbf9 made it possible to give a compiler option to set {source,...}. ERL-310
2016-11-18compile_SUITE: Make sure that guards are optimizedBjörn Gustavsson
Guards should use the more efficient 'test' instructions, not 'bif' instructions. Add a test to make sure that the optimizations don't degrade. We do have to keep an exception list for functions where we can't replace all 'bif' calls with 'test' instructions. We try to keep that list a short as practically possible.
2016-11-18Add test using LFE-generated Core Erlang modulesBjörn Gustavsson
Ensure that correct (not necessarily optimal) code is generated for Core Erlang code not originating from v3_core.
2016-11-18Remove beam_boolBjörn Gustavsson
The guard optimizations in v3_kernel has removed the need for beam_bool.

2016-09-01compiler: Eliminate use of sys_pre_expandBjörn Gustavsson
sys_pre_expand previously did a lot more work, for example, translating records and funs, but now is merely a grab bag of small transformations. Move those transformations to v3_core.
2016-06-07Compiler: new function env_compiler_options/0alisdair sullivan
retrieve the value of the environment variable ERL_COMPILER_OPTIONS in the same manner as used by file/2, forms/2 and output_generated/2
2016-05-13compile_SUITE: Cover numeric variable names in core_ppBjörn Gustavsson
The inliner generates variable whose names are numeric. Run the inliner to cover one more line in core_pp.
2016-05-13compile_SUITE: Eliminate clones when re-compiling test suitesBjörn Gustavsson
Several test cases in compile_SUITE (e.g. core/1) extracts the abstract code from a BEAM file and runs the compiler on it. It is only a waste of time to use the abstract code from cloned versions of test case modules. That is, use record_SUITE, but don't use record_no_opt_SUITE, record_post_opt_SUITE, or record_inline_SUITE since they all contain essentially the same abstract code.
2016-04-27Remove toothless test compile_SUITE:missing_testheap/1Björn Gustavsson
missing_testheap/1 is no longer relevant for the following reasons: 1) Because of the literal pool introduced in R12, no test_heap instructions are needed in the guards. 2) beam_validator would abort the compilation if any needed test_heap instructions were missing.
2016-04-25compiler: Remove use of crypto:rand_bytes/1Ingela Anderton Andin
Use case in compile.erl is cryptographical so use crypto:strong_rand_bytes/1 instead. Use case in test suite is not cryptographical so use other test instead.
2016-04-21Add compile_SUITE:core_roundtrip/1Björn Gustavsson
When debugging, it is important that we can trust the Core Erlang pretty printer and Core Erlang parser.

2016-03-24Fix compile:forms/1,2 crash when not in an existing directoryBjörn Gustavsson
compile:forms/1,2 will crash when the current working directory has been deleted. Fix that problem, and while we are at it, also stop including {source,""} in module_info() when no source code file is given. Reported-at: http://bugs.erlang.org/browse/ERL-113 Reported-by: Adam Lindberg
2016-03-17compile: Pre-load compiler modules when invoked from 'erlc'Björn Gustavsson
Slightly speed up 'erlc' by pre-loading the modules used by the compiler. Write a test case to ensure that the correct set of modules are loaded.

Either rely on the default 30 minutes timetrap, or set the timeout using the supported methods in common_test.
2016-02-17Eliminate use of test_server.hrl and test_server_line.hrlBjörn Gustavsson
As a first step to removing the test_server application as as its own separate application, change the inclusion of test_server.hrl to an inclusion of ct.hrl and remove the inclusion of test_server_line.hrl.
2016-02-05Move record compilation errors to erl_lint_SUITEBjörn Gustavsson
The two bad record usage test cases in compile_SUITE do not belong there, as the errors are detected in erl_lint. Move the test to the erl_lint_SUITE.
2016-02-05compile_SUITE: Use get_files/3 in more placesBjörn Gustavsson
2016-02-05compile_SUITE: Replace confusing files/2 with get_files/3Björn Gustavsson
The files/2 function is confusing. The second argument names the output directory, not the name of the source module. It is common trap to attempt to point a different source file using files/2. Introduce the new get_files/3 which explicitly names the module name.
2015-09-28Move out bit syntax optimizations from beam_blockBjörn Gustavsson
In the future we might want to add more bit syntax optimizations, but beam_block is already sufficiently complicated. Therefore, move the bit syntax optimizations out of beam_block into a separate compiler pass called beam_bs.
2015-09-10compile_SUITE: Add test of warningsBjörn Gustavsson
Make sure that all warnings produced when compiling the test suite contains filenames and line numbers.

To run eprof for a compiler pass: erlc +'{eprof,beam_asm}' file.erl The name of the compiler pass is the name as printed when 'time' option is used. It is usually, but not always, the module name for the compiler pass.
2015-01-27Strengthen and modernize compile_SUITEBjörn Gustavsson
When we compile from Core Erlang, do it with and without Core Erlang optimizations to ensure that we are not dependent on the optimizations always being run.

2013-12-18Officially support building assembler filesTuncer Ayaz
erlc is wired to treat *.S files as assembler and build them as compile:file(File, [from_asm]), but this is not documented. There's also a documented compile:file/2 option called 'asm' (mapping to 'from_asm'), but the wording discourages its use. All of this has been in place and in use for a long time. Therefore, it should be supported officially. To fix that, make the following changes: * document erlc handling of *.core files * un-document 'asm' and document 'from_asm' instead * deprecate 'asm' While at it, fix a minor typo in the test suite.

2013-09-05compiler: Conform returned errors to the documented formatBjörn Gustavsson
ErrorInfo is documented to be: {ErrorLine,Module,ErrorDescriptor} but for some errors with line numbers it would look like: {Module,ErrorDescriptor} Ensure that all ErrorInfo tuples have three elements. Use 'none' instead of a line number: {none,Module,ErrorDescriptor} There already are errors that return 'none' when no line number is available, but that convention was not documented. Mention it in the documentation. Also make sure that the compiler will not print 'none' as a line number in error messages (if the 'report_errors' option is given) as that looks stupid. That is, when attempting to compile a non-existing module, the error message should be: non-existing.erl: no such file or directory and not: non-existing.erl:none: no such file or directory

2013-05-20beam_lib, compile: Replace use of deprecated crypto functionsBjörn Gustavsson
Since both the STDLIB and compiler applications turn warnings into errors, we must stop using the old deprecated crypto functions. While we are at it, generalize the format of the key tuple returned by beam_lib:make_crypto_key/2 to facilitate introducing new crypto methods in the future. Change the format to: {Type,Key,IV,BlockSize} where Type, Key, and IV are the first three arguments for either crypto:block_encrypt4/ or crypto:block_decrypt/4, and BlockSize is the block size for the crypto algorithm (it is needed to properly pad the plaintext blocks before encryption).
