2011-11-28hipe: Remove single function compilationBjörn Gustavsson
Compiling single functions (as opposed to whole modules) to native code complicates code management in HiPE. It would also vastly complicate whole-module optimizations, such as returning multiple return values instead of tuples within a module. As a first step, remove the external interface for the single compilation feature. In the future, there are many things that could be restructured and simplified.

2011-11-17hipe: Fix bug in hipe_rtl_lcm:calc_killed_expr_bbSverker Eriksson
Bug causing hipe to crash. Only provoked when changing the RTL generation for floating point operations. hipe_rtl:defines() was called with a expression ID instead of an expression. Use expr_id_map_get_expr() to get expression from ID. Need to pass along IdMap in order to do that.

2011-11-09erts,hipe: Limited support for hipe cross compilationSverker Eriksson
Normally hipe assumes that generated native code will be executed on the same emulator as the hipe compiler is running on. This commit allows you to build a hipe "cross-compiler" for a different configured emulator (but for same architecture). Example: > cd lib/hipe > make clean > make XCOMP=yes FLAVOR=smp TYPE=debug This hipe compiler will generate code to be executed on the debug compiled smp-emulator at $ERL_TOP.

2011-09-21erl_bif_types: Fix types for lists:key{search,find,member}/3Björn Gustavsson
The types for lists:key{search,find,member}/3 was computed under the assumption that the key should be matched (=:=) to the keys in the list, while the actual implementation uses comparison (==). Thus erl_bif_types:types/4 would wrongly report that lists:keyfind(42, 1, [{42.0,a}]) would always return 'false'.

2011-09-16Quote atoms if necessary in typesTomas Abrahamsson
Atoms in some occurrences were not correctly quoted when formatted to strings, for instance by the typer program. Example: -module(tb). -export(['UPPERCASE-FUNCTION-NAME'/0, f1/0, f2/0, f3/0]). -record('UPPERCASE-RECORD-NAME', {x}). -record(r2, {'UPPERCASE-FIELD-NAME'}). -type 'UPPERCASE-TYPE-NAME'() :: integer(). 'UPPERCASE-FUNCTION-NAME'() -> ok. f1() -> #'UPPERCASE-RECORD-NAME'{x=1}. f2() -> #r2{'UPPERCASE-FIELD-NAME'=1}. -spec f3() -> 'UPPERCASE-TYPE-NAME'(). f3() -> 1. Given the program above, the output from typer --plt some.plt tb.erl resulted in the following specs being printed: -spec UPPERCASE-FUNCTION-NAME() -> 'ok'. -spec f1() -> #UPPERCASE-RECORD-NAME{x::1}. -spec f2() -> #r2{UPPERCASE-FIELD-NAME::1}. -spec f3() -> UPPERCASE-TYPE-NAME(). This commit changes the output to become the following: -spec 'UPPERCASE-FUNCTION-NAME'() -> 'ok'. -spec f1() -> #'UPPERCASE-RECORD-NAME'{x::1}. -spec f2() -> #r2{'UPPERCASE-FIELD-NAME'::1}. -spec f3() -> 'UPPERCASE-TYPE-NAME'().

2011-08-29Enhance Dialyzer's inference on comparisonsStavros Aronis
This patch makes Dialyzer aware of Erlang's total ordering of terms, enabling discrepancy detection in cases where e.g. integer() < tuple() is treated as a comparison that might also return false (when it is certain to always return true).

Add erlang:check_old_code/1 to quickly check whether a module has old code. If there is no old code, there is no need to call erlang:check_process_code/2 for all processes, which will save some time if there are many processes.
2011-08-16emulator: Add a fourth element in exception stacktracesBjörn Gustavsson
This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces.
