The test 'proper' takes some time.

Fix a mistake in commit 85f6fe3b.
Instead of using the declared opaque type, the form's type is used in
a case where the opaque type is turned into a non-opaque type. The
result is more general types (smaller Erlang terms) and faster
analyses.

The code purger process handles vast amounts of messages when
there are lots of processes alive. A single message in the
message queue that does not match will in such cases cause
lots of extra work. The code purger process now always picks
the first message in the message queue, and by this avoid
this extra work.

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_sparc_main.

This is primarily useful for heap allocations, as a two-address 'add'
can't be used to both copy the heap pointer to another register, and add
the tag.

The ARM backend crashes if certain RTL optimisations were omitted,
preventing it from being usable at lower optimisation levels.
One of the problems were caused by shift-by-immediate-zero, which wraps
to immediate-32 with some shiftops. TODO: Someplace should be modified
to crash when these are generated so debuging further instances of this
gets easier in the future.

For x86, additionally reuse liveness from float LSRA for the GP LSRA.

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.

These options would not do anything, because they would not supress the
'o2' in ?COMPILE_DEFAULTS. Such behaviour is added to expand_options/2.
|
|
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.
|
|
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.

|
|
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.
