2018-09-28hipe: Document new limitations and disable known failing testsJohn Högberg

2018-06-11Fix a crash ih HoPE's lazy code motion passKostis Sagonas
Some change in the BEAM compiler resulted in the creation of basic blocks that differed from those previously created by the compiler. As a result, the lazy code motion pass of RTL crashed when compiling some of the new code. Crashes were privately reported by @richcarl.
2018-01-22Don't build a stacktrace if it's only passed to erlang:raise/3Björn 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.

2017-10-11hipe: Extend the basic_SUITE with one more testKostis Sagonas
that checks the construction of exception information. The test is taken from the compiler SUITE but part of it (the one that constructs exceptions which differ between BEAM and HiPE) is commented out. Related to the discussion of #1596.
2017-03-27hipe: Fix range analysis of calls with ignored resMagnus Lång
HiPE's range analysis would not update the arguments of a callee when the result of the call was ignored. Fixes ERL-278.
2017-03-16hipe: Add basic_edge_cases test caseMagnus Lång
Two tests are added, primarily aimed at the range splitters. * test_float_spills, which exercises the rare case of high floating point register pressure, including spill slot move coalescing. * test_infinite_loops, which tests that various infinite loops are properly compiled and do contain reduction tests (otherwise they would permanently hog their scheduler and not notice being sent an exit signal).
2017-03-06hipe: Improve code generation for element/2Magnus Lång
* Omit bounds check in more cases. A test case that needs this change to omit bounds check is added. * Improve code generation by reformulating bounds check to decrease register pressure.

2016-03-02hipe: Fix crashing bugs when inlining FP opsMagnus Lång
It was assumed in hipe_icode_fp:filter_map/3 that either all predecessors would have an up-to-date ("assigned") tagged copy, or none of them. This is temporarily false during the fixpoint loop in basic_floats:test_icode_type_crash_2/0, which exercises the all_args_equal(Bindings) =:= true branch, that would previously erroneously end up in the 'false' branch, which is what caused the crash in that case. This is likewise only temporarily false during the fixpoint loop in basic_floats:test_icode_type_crash/0, but that case instead exercises the 'false' branch, justifying the inclusion of both tests.
