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.

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. --- lib/compiler/doc/src/compile.xml | 25 +++++++++++++++++++------ 1 file changed, 19 insertions(+), 6 deletions(-) (limited to 'lib/compiler/doc/src') diff --git a/lib/compiler/doc/src/compile.xml b/lib/compiler/doc/src/compile.xml index ed04dac1c0..94bda0d5e3 100644 --- a/lib/compiler/doc/src/compile.xml +++ b/lib/compiler/doc/src/compile.xml @@ -132,12 +132,10 @@ debug_info -

The problem is that the stacktrace is kept until the next exception occurs. If the last exception was a 'function_clause' or a 'badarg', the arguments for the call are also kept forever. The arguments can be terms of any size (potentially huge). In a future release, we would like to only allow erlang:get_stacktrace/0 from within a 'try' expression. That would make it possible to clear the stacktrace when the 'try' expression is exited. The 'catch' expression has no natural end where the stacktrace could be cleared. The stacktrace could be cleared at the end of the function that the 'catch' occurs in, but that would cause problems in the following scenario (from real life, but simplified): try ... catch _:_ -> io:format(...), io:format("~p\n", [erlang:get_stacktrace()]) end. %% In io.erl. format(Fmt, Args) -> Res = case ... of SomePattern -> catch... ...; SomeOtherPattern -> %% Output the formatted string here ... end, clear_stacktrace(), %% Inserted by compiler. Res. The call to io:format() would always clear the stacktrace before it could be retrieved. That problem could be solved by tightning the scope in which the stacktrace is kept, but the rules for how long erlang:get_stacktrace/0 would work would become complicated. Therefore, the solution we suggest for a future major release of OTP is that erlang:get_stacktrace/0 will return [] if it is called outside the 'catch' part of a 'try' expression. To help users prepare, introduce a warning when it is likely that erlang:get_stacktrace/0 will always return an empty list, for example in this code: catch error(foo), Stk = erlang:get_stacktrace() or in this code: try Expr catch _:_ -> ok end, Stk = erlang:get_stacktrace() --- lib/compiler/doc/src/compile.xml | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'lib/compiler/doc/src') diff --git a/lib/compiler/doc/src/compile.xml b/lib/compiler/doc/src/compile.xml index fed68037c1..10164890f2 100644 --- a/lib/compiler/doc/src/compile.xml +++ b/lib/compiler/doc/src/compile.xml @@ -629,6 +629,14 @@ module.beam: module.erl \

Compiler 7.2 + +
Fixed Bugs and Malfunctions + + +

Fixed an error in an optimization pass that caused + impossible tuple matching.

+ Own Id: OTP-14855 Aux Id: ERL-549

+ + +

The exception thrown when a list comprehension was + given a non-list term was not always correct.

+

+ Own Id: OTP-14992 Aux Id: ERL-572

+ + +
+ + +
Improvements and New Features + + +

Changed the default behaviour of .erlang + loading: .erlang is no longer loaded from the + current directory. c:erlangrc(PathList) can be + used to search and load an .erlang file from user + specified directories.

escript, + erlc, dialyzer and typer no longer + load an .erlang at all.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-14439

+ + +

Support for "tuple calls" have been removed from the + run-time system. Tuple calls was an undocumented and + unsupported feature which allowed the module argument for + an apply operation to be a tuple: Var = dict:new(), + Var:size(). This "feature" frequently caused + confusion, especially when such call failed. The + stacktrace would point out functions that don't exist in + the source code.

+

For legacy code that need to use parameterized modules + or tuple calls for some other reason, there is a new + compiler option called tuple_calls. When this + option is given, the compiler will generate extra code + that emulates the old behavior for calls where the module + is a variable.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-14497

+ + +

In code such as example({ok, Val}) -> {ok, + Val}. a tuple would be built. The compiler will now + automatically rewrite the code to + example({ok,Val}=Tuple) -> Tuple. which will + reduce code size, execution time, and remove GC + pressure.

+

+ Own Id: OTP-14505

+ + +

The optimization of case expression where only + one of the case arms can execute successfully has been + improved.

+

+ Own Id: OTP-14525

+ + +

Some uses of binary matching has been slightly + improved, eliminating unnecessary register shuffling.

+

+ Own Id: OTP-14594 Aux Id: ERL-444

+ + +

There is a new {compile_info,Info} option for + the compiler that allows BEAM-based languages such as + Elixir and LFE to add their own compiler versions.

+

+ Own Id: OTP-14615 Aux Id: PR-1558

+ + +

Loaded BEAM code in a 64-bit system requires less + memory because of better packing of operands for + instructions.

+

These memory savings were achieved by major + improvements to the beam_makeops scripts used when + building the run time system and BEAM compiler. There is + also new for documentation for beam_makeops that + describes how new BEAM instructions and loader + transformations can be implemented. The documentation is + found in here in a source directory or git repository: + erts/emulator/internal_doc/beam_makeops.md. An online + version can be found here: + https://github.com/erlang/otp/blob/master/erts/emulator/internal_doc/beam_makeops.md

+

+ Own Id: OTP-14626

+ + +

Size calculations for binary constructions has been + somewhat optimized, producing smaller code.

+

+ Own Id: OTP-14654

+ + +

When the value returned from a 'catch' + expression is ignored, no stacktrace will be built if an + exception is caught. That will save time and produce less + garbage. There are also some minor optimizations of + 'try/catch' both in the compiler and + run-time system.

+

+ Own Id: OTP-14683

+ + +

There is a new syntax in 'try/catch' for + retrieving the stacktrace without calling + 'erlang:get_stacktrace/0'. See the reference + manual for a description of the new syntax. The + 'erlang:get_stacktrace/0' BIF is now + deprecated.

+

+ Own Id: OTP-14692

+ + +

The following is an internal change in the compiler, + that is not noticeable for normal use of the compiler: + The module v3_life has been removed. Its + functionality has been simplified and integrated into + v3_codegen.

+

+ Own Id: OTP-14712

+ + +

The optimization of binary matching that delays + creation of sub binaries (see the Efficiency Guide) could + be thwarted by the argument order and could be necessary + to change the argument order. The compiler has now become + smarter and can handle any argument order.

+

+ Own Id: OTP-14774

+ + +

When the compiler was faced with complex case + expressions it would unnecessarily allocate stack + elements and shuffle data between x and y registers. + Improved code generation to only allocate a stack frame + when strictly necessary.

+

+ Own Id: OTP-14808 Aux Id: ERL-514

+ + +

There is a new option 'makedep_side_effect' for + the compiler and -MMD for 'erlc' that + generates dependencies and continues to compile as + normal.

+

+ Own Id: OTP-14830

+ + +

When compiling modules with huge functions, the + compiler would generate a lot of atoms for its internal, + sometimes so many that the atom table would overflow. The + compiler has been rewritten to generate far less internal + atoms to avoid filling the atom table.

When specified, the +{source,Name} option will + now override the actual file name in stack traces, + instead of only affecting the return value of + Mod:module_info().

+

The +deterministic flag will also affect stack + traces now, omitting all path information except the file + name, fixing a long-standing issue where deterministic + builds required deterministic paths.
