2015-01-14beam_bool: Correct live calculation for GC BIFsBjörn Gustavsson
When optimizing boolean expressions, it is not always possible to find a number of live registers for a GC BIF that both preserves all source registers that will be tested and at the same time does not include registers that are not initialized. As currently implemented, we have incomplete information about the register calculated from the free variables. Some registers are marked as "reserved". Reserved registers means that we don't know anything about them; they may or may not be initialized. As a conservative correction (suitable for a maintenance release), we will abort the optimization if we find any reserved registers when calculating the number of live registers. We will not attempt to improve the information about the registers in this commit. By examining the coverage when running the existing compiler test suite we find that the optimization is aborted 15 times (before adding any new test cases). To put that in perspective, the optimization is successfully applied 4927 times, and aborted for other reasons 547 times. Reported-by: Ulf Norell Reported-by: Anthony Ramine
2015-01-14beam_bool: Correct indentation for try...catchBjörn Gustavsson
Old versions of the Erlang mode for Emacs used to indent try...catch strangely - the first clause following the 'catch' would be indented with one space less than the following clauses. If we are to use the new Erlang mode when we add more clauses, they would be indented with one space less than the preceding clauses. That would look silly.
2015-01-14sys_core_fold: Correct optimization of 'case'Björn Gustavsson
The optimization of a 'case' statement could lead to incorrect code that would cause an exception at run-time. Here is an example to show how the optimization went wrong. Start with the following code: f({r,#{key:=Val},X}=S) -> case S of {r,_,_} -> setelement(3, Val, S) end. (The record operations have already been translated to the corresponding tuple operations.) The first step in case_opt/3 is to substitute S to obtain: f({r,#{key:=Val},X}=S) -> case {r,#{key:=Val},X} of {r,_,_} -> setelement(3, Val, S) end. After that substitution the 'case' can be simplified to: f({r,#{key:=Val},_}=S) -> case #{key:=Val} of NewVar -> setelement(3, Val, S) end. That is the result from case_opt/3. Now eval_case/2 notices that since there is only one clause left in the 'case', the 'case' can eliminated: f({r,#{key:=Val},_}=S) -> NewVar = #{key:=Val}, setelement(3, Val, S). Since the map construction may have a side effect, it was not eliminated, but assigned to a variable that is never used. The problem is that '#{key:=Val}' is fine as a pattern, but in a construction of a new map, the '=>' operator must be used. So the map construction will fail, generating an exception. As a conservative correction for a maintenance release, we will abort the 'case' optimization if the substitution into the 'case' expression is anything but data items (tuples, conses, or literals) or variables.

2015-01-11hipe: rtl: fix phi_remove_pred/2 FP movesMikael Pettersson
hipe_rtl:phi_remove_pred/2 can produce a #move{} instruction with floating-point temporaries as operands, even though such moves MUST be #fmove{} instructions. Added type checks to the #move{} and #fmove{} constructor and setter functions to ensure that similar mishaps cannot happen again.
2015-01-11hipe: backends: correct #fconv{} translationMikael Pettersson
RTL can produce an #fconv{} instruction with an immediate operand, but the backends unconditionally access the operand as a temporary. This results in broken representation in the backends and eventually they crash.
