2016-08-30hipe: Reuse liveness info for spillminMagnus Lång
For x86, additionally reuse liveness from float LSRA for the GP LSRA.
2016-08-30hipe_x86: Minimise CFG<->linear conversionsMagnus Lång
Most x86 passes were either linearise(pass(to_cfg(Code))) or trivially rewritable to process a CFG. This saves a great deal of time and memory churn when compiling large programs. Now, there will only ever be a single Linear->CFG conversion, just after lowering from RTL, and only ever a single CFG->Linear conversion, just before the finalise pass. Both of these now happen in hipe_x86_main.

2016-08-30hipe: Fix o0 and o1Magnus Lång
These options would not do anything, because they would not supress the 'o2' in ?COMPILE_DEFAULTS. Such behaviour is added to expand_options/2.
2016-08-30hipe: Add o0 and o1 to testsMagnus Lång
Now that x86 is no longer broken with these optimisation levels, we add them to the test suite to ensure they do not break again. Bump timeout to 6min since tests are run twice as many times. The option set of o1 was changed to all optimisations that run fast on both big and small programs, incurring only a slight compile time increase compared to the old set, but with a, presumably, significant improvement to speed of compiled code. Change o0 register allocator to linear_scan.
2016-08-30hipe_rtl_binary:get_word_integer/4: Handle immsMagnus Lång
Immediate arguments to get_word_integer/4 would lead to bad but unreachable RTL being generated. We omit its generation by testing for immediates and performing the logic at compile time.
2016-08-30hipe_x86: Be resilient to crappy RTLMagnus Lång
The x86 backend crashes if certain RTL optimisations were omitted, preventing it from being usable at lower optimisation levels.
2016-08-30hipe_x86: LSRA for SSE2Magnus Lång
There is little point offering LSRA for x86 if we're still going to call hipe_graph_coloring_regalloc for the floats. In particular, all allocators except LSRA allocates an N^2 interference matrix, making them unusable for really large functions.

2016-08-29Fix purge of codeRickard Green
Ensure that we cannot get any dangling pointers into code that has been purged. This is done by a two phase purge. At first phase all fun entries pointing into the code to purge are marked for purge. All processes trying to call these funs will be suspended and by this we avoid getting new direct references into the code. When all processes has been checked, these processes are resumed. The new purge strategy now also completely ignore the existence of indirect references to the code (funs). If such exist, they will cause bad fun exceptions to the caller, but will not prevent a soft purge or cause a kill of a process having such live references during a hard purge. This since it is impossible to give any guarantees that no processes in the system have such indirect references. Even when the system is completely clean from such references, new ones can appear via distribution and/or disk.

2016-08-26Eliminate catch-all clause from two functionsKostis Sagonas
A stronger version of Dialyzer complained that some case clauses in functions xaluop_is_shift/1 and xaluop_normalise/1 are unreachable. These clauses are now commented out. While at it, I thought that it would be better to eliminate the catch-all clauses in order to be certain we properly handle all RTL instructions that are used as inputs to these functions. Note: The code will now crash if there are unhandled cases.
