* bjorn/compiler-options/OTP-9534: sys_pre_expand: Don't duplicate options given in the source code
2011-09-14sys_pre_expand: Don't duplicate options given in the source codeBjörn Gustavsson
Any compiler options given with a -compile() attribute in source file would be included both at the beginning and the end of the option list for the compiler. Including the options twice is harmless during compilation, but since the options will also be available in Mod:module_info(compile), including them twice will waste memory. Include the options from the source first in the list so that they override options given on the command line.

2011-04-12bs_match_SUITE: Improve coverage of beam_bsmBjörn Gustavsson
2011-04-12beam_bsm: Eliminate uncovered line in warning generationBjörn Gustavsson
In warning_translate_label/2, gb_trees:lookup/2 is called to translate from the entry label for a function to its name. Since the gb_tree has an entry for all functions in the module, there is no way that the lookup can fail unless there is a serious bug. Therefore, use gb_trees:get/2 so that an exception and an internal compiler error will be generated if the lookup would ever fail.
2011-04-12match_SUITE: Cover a clause in beam_dead:forward/4Björn Gustavsson
2011-04-12beam_dead: Remove uncovered special case handling of empty blocksBjörn Gustavsson
There is never any empty blocks when beam_dead is invoked. Even if there were, they will be removed a little bit later in forward/4.
2011-04-12beam_dead: Remove uncovered clauses in binary matching optimizationBjörn Gustavsson
In the optimization of binary matching, it seems that two clauses cannot never be reached. Removing the clauses is safe, since that would only mean that an opportunity for an optimization is lost
2011-04-12beam_dead: Remove uncoverable case clause in update_value_dict/3Björn Gustavsson
Because the code generator (v3_codegen) would not include the same value more than once in a select_val/3 instruction and because a label can only be referenced by one select_val/3 instruction, there is no way that the correct value could already be in the gb_tree. (Even if it could happen, this change is safe because only opportunity for an optimization would be missed; incorrect code would not be generated.)
2011-04-12beam_dead: Remove code that cannot be covered in forward/4Björn Gustavsson
Since the optimizations in forward/4 already depends on some assumptions on how code is generated anyway, document the assumptions in a comment and remove the uncoverable code.
2011-04-12record_SUITE: Cover optimization of is_record/3 in beam_typeBjörn Gustavsson
Since the introduction of improved record optimizations in 1858cb81391d2bce29b4b7620574ca60128cebf7 and 470c91d43eae54f63661645acbce4b92d73287cc, the optimization of a is_record/3 call with a known correct type in beam_type:simplify_basic_1/3 has not been covered.
2011-04-12compiler tests: Reinstate ?MODULE macro in calls to test_lib:recompile/1Björn Gustavsson
In 3d0f4a3085f11389e5b22d10f96f0cbf08c9337f (an update to conform with common_test), in all test_lib:recompile(?MODULE) calls, ?MODULE was changed to the actual name of the module. That would cause test_lib:recompile/1 to compile the module with the incorrect compiler options in cloned modules such as record_no_opt_SUITE, causing worse coverage.

2011-03-29beam_dict: Eliminate the redundant next_atom record elementBjörn Gustavsson
It is not needed because it can be trivially calculated using gb_trees:size/1.

2011-03-25sys_core_fold: Eliminate incorrect warningBjörn Gustavsson
The compiler (sys_core_fold) tries to avoid constructing tuples in case expressions. The following code: c(A, B) -> case {A,B} of {ok,X} -> X; {_,_} -> error end. will be rewritten so that no tuple is built. If a clause requires a tuple to be built as in this code: c(A, B) -> case {A,B} of {ok,X} -> X; V -> V %The tuple will be built here end. the tuple will be built in the clause(s) in which it is needed. If the value returned from the case is not used as in this code: c(A, B) -> case {A,B} of V -> V %Warning: a term is constructed, but never used end, ok. there will be an incorrect warning. Basically, what happens is that the code is reduced to: c(A, B) -> {A,B}, %Warning: a term is constructed, but never used ok. and the optimizer sees that the {A,B} tuple can't possibly be used. Eliminate the warning by adding a 'compiler_generated' annotation to the tuple. Reported-by: Kostis Sagonas
2011-03-25sys_core_fold: Be careful to preserve annotations while optimizingBjörn Gustavsson
2011-03-23v3_core: Fix variable incorrectly unbound after binary matchBjörn Gustavsson
In the following code: m(<<Sz:8,_:Sz/binary>>) -> Sz = wrong. the Sz variable is supposed to be bound in the function header and the matching "Sz = wrong" should cause a badarg exception. But what happens is that the Sz variables seems to be unbound and the matching succeds and the m/1 function returns 'wrong'. If the Sz variable is used directly (not matched), it will have the expected value. Thus the following code: m(<<Sz:8,_:Sz/binary>>) -> Sz. will correctly return the value of Sz that was matched out from the binary. Reported-by: Bernard Duggan

* jp/dependencies_makefile: Add dependencies Makefile generation to erlc(1) and compile(3) Conflicts: lib/compiler/test/compile_SUITE.erl OTP-9065
2011-02-18Add dependencies Makefile generation to erlc(1) and compile(3)Jean-Sébastien Pédron
This is useful when a project is built with Makefiles and erlc(1) instead of EMakefiles. Tracking dependencies by hand is error-prone and it becomes painful when using external application headers like EUnit's one. A dependencies Makefile will look like this: module.beam: module.erl \ /usr/local/lib/erlang/lib/eunit-2.1.4/include/eunit.hrl \ header.hrl When included in the main Makefile, 'module' will be recompiled only when needed. GCC offers the same feature and new erlc(1) options are compatible with it. More informations at: http://wiki.github.com/dumbbell/otp/dependencies-makefile

2011-02-14compile: Refactor handling of source options (e.g. 'from_core')Björn Gustavsson
The options for compiling from Core Erlang, BEAM assembler files, and BEAM files are handled in several places, making it difficult to change or add more similar options. Refactor the option handling so that each option only need to be handled in one place.

2010-12-21compiler: Don't include -export_type as attributes in BEAM filesBjörn Gustavsson
Similar to -spec and -type, -export_type should be not be included as attributes (and therefore loaded) in BEAM files, but only in the abstract code chunk.
