2017-11-30Add syntax in try/catch to retrieve the stacktrace directlyBjörn 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 -> . . .
2017-11-30erl_parse: Use a new pat_expr rule for pattern expressionsBjörn Gustavsson
In the grammar file for the Erlang language, patterns are parsed as expressions. erl_lint will then weed out expressions that are not legal patterns. The rule sharing causes problems if we were to introduce new syntax, for example a pattern followed by a ':'. There would be a shift/reduce conflict, and a pattern followed by a ':' would be parsed as a remote call. Introduce a new pat_expr rule to express exactly the subset of expressions that is allowed in pattern. Note: For the moment, we must allow full expressions in case clauses to keep 'merl' working.

2017-11-29v3_codegen: Remove check of operand for bs_context_to_binaryBjörn Gustavsson
The bs_context_to_binary instruction only allows a register operand. v3_codegen has a test to ensure that the operand is a register. That test is no longer necessary. There used to be a possibility that optimizations in sys_core_fold and the inliner could change the operand for bs_context_to_binary to a binary literal. Since 09112806c15a81b that can no longer happen, because no more optimizations are run after the introduction of the bs_context_to_binary instruction.

2017-11-27beam_asm: No longer allow iolists as contents in chunk/2Björn Gustavsson
The clause that converted an iolist to a binary was never executed. Note that chunk/2 is called for all chunks in the {extra_chunks,Chunks} option. This change will enforce that the contents of each chunk must be a binary (as documented).
2017-11-27beam_utils_SUITE: Cover more lines in beam_utilsBjörn Gustavsson
2017-11-27guard_SUITE: Add a test case to cover beam_dead:turn_op/1Björn Gustavsson
f9a323d10a9f5d added consistent operand order for equality comparisons. As a result, beam_dead:turn_op/1 is no longer covered. We must keep the uncovered lines in beam_dead to ensure that beam_dead can handle BEAM assembly code from another source than v3_codegen that might not follow the operand order convention. The only way to cover the lines is to use BEAM assembly in the test case.
2017-11-27Recognize 'nil' as a literal in beam_utils:bif_to_test/3Björn Gustavsson
beam_utils:bif_to_test/3 is supposed to never put a literal operand as the first operand in is_eq_exact or is_ne_exact, but 'nil' was not recognized as a literal.

The loader has a lot of fused instructions that include move S x0. Placing them at the end of blocks makes it possible to take advantage of this optimization more frequently.
