| 2018-01-22 | Don't build a stacktrace if it's only passed to erlang:raise/3 | Björn Gustavsson | |
| Consider the following function: function({function,Name,Arity,CLabel,Is0}, Lc0) -> try %% Optimize the code for the function. catch Class:Error:Stack -> io:format("Function: ~w/~w\n", [Name,Arity]), erlang:raise(Class, Error, Stack) end. The stacktrace is retrieved, but it is only used in the call to erlang:raise/3. There is no need to build a stacktrace in this function. We can avoid the building if we introduce an instruction called raw_raise/3 that works exactly like the erlang:raise/3 BIF except that its third argument must be a raw stacktrace. | |||

| 2017-11-30 | Add syntax in try/catch to retrieve the stacktrace directly | Björn Gustavsson | |
| This commit adds a new syntax for retrieving the stacktrace without calling erlang:get_stacktrace/0. That allow us to deprecate erlang:get_stacktrace/0 and ultimately remove it. The problem with erlang:get_stacktrace/0 is that it can keep huge terms in a process for an indefinite time after an exception. The stacktrace can be huge after a 'function_clause' exception or a failed call to a BIF or operator, because the arguments for the call will be included in the stacktrace. For example: 1> catch abs(lists:seq(1, 1000)). {'EXIT',{badarg,[{erlang,abs, [[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20|...]], []}, {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,674}]}, {erl_eval,expr,5,[{file,"erl_eval.erl"},{line,431}]}, {shell,exprs,7,[{file,"shell.erl"},{line,687}]}, {shell,eval_exprs,7,[{file,"shell.erl"},{line,642}]}, {shell,eval_loop,3,[{file,"shell.erl"},{line,627}]}]}} 2> erlang:get_stacktrace(). [{erlang,abs, [[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22, 23,24|...]], []}, {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,674}]}, {erl_eval,expr,5,[{file,"erl_eval.erl"},{line,431}]}, {shell,exprs,7,[{file,"shell.erl"},{line,687}]}, {shell,eval_exprs,7,[{file,"shell.erl"},{line,642}]}, {shell,eval_loop,3,[{file,"shell.erl"},{line,627}]}] 3> We can extend the syntax for clauses in try/catch to optionally bind the stacktrace to a variable. Here is an example using the current syntax: try Expr catch C:E -> Stk = erlang:get_stacktrace(), . . . In the new syntax, it would look like: try Expr catch C:E:Stk -> . . . Only a variable (not a pattern) is allowed in the stacktrace position, to discourage matching of the stacktrace. (Matching would also be expensive, because the raw format of the stacktrace would have to be converted to the cooked form before matching.) Note that: try Expr catch E -> . . . is a shorthand for: try Expr catch throw:E -> . . . If the stacktrace is to be retrieved for a throw, the 'throw:' prefix must be explicitly included: try Expr catch throw:E:Stk -> . . . | |||

| 2017-11-06 | erts: Remove obsolete hipe primop bs_validate_unicode | Sverker Eriksson | |
| which was replaced by 'is_unicode' in 5369e34a892bfd8ab5aa98df330e3bbf19497b71 but kept for ABI compatibility in OTP-20.*. | |||
| 2017-11-05 | HiPE: Make is_divisible a primop | Magnus Lång | |
| Since gcunsafe values are live over is_divisible calls (although only the happy path, which never GCd), it should be a primop so there cannot be any GCs. | |||

| 2017-11-03 | Fix bug in hipe for <<X/utf32>> | Sverker Eriksson | |
| by introducing new primop 'is_unicode' with no exception (ab)use and no GC. Replaces bs_validate_unicode which is kept for backward compat for now. | |||

| 2015-11-27 | hipe: test unit size match in bs_append | Magnus Lång | |
| This feature was previously missing and expressions such as <<<<1:1>>/binary>> would succeed construction when compiled with HiPE. A primop is_divisible is introduced to handle the case when the unit size is not a power of two. | |||

| 2015-04-20 | erts,hipe: Fix bug in binary matching of writable binary | Sverker Eriksson | |
| Seen symptom: Hipe compiled code with <<C/utf8, ...>> = Bin does sometimes not match even though Bin contains a valid utf8 character. There might be other possible binary matching symptoms, as the problem is not utf8 specific. Problem: A writable binary was not "emasculated" when the matching started (as it should) by the hipe compiled code. Fix: Add a new primop emasculate_binary(Bin) that is called when a matchstate is created. ToDo: There are probably room for optimization. For example only call emasculate_binary if ProcBin.flags is set. | |||

| 2011-10-26 | erts-hipe: Make some primops use new BIF calling convention | Sverker Eriksson | |
| These primops use the standard_bif_interface_X macros in hipe_bif_list.m4 and must therefor be implemented as bifs for things to work. Maybe there is room for optimization here to call the primops more directly with arguments in registers without having to push them on stack to emulate bif calls. | |||
