2016-04-29erts: Add literal_mmap and exec_mmap to system_infoSverker Eriksson
erlang:system_info(allocator) -> {Allocator, Version, Features, Settings} Features includes 'literal_mmap' and/or 'exec_mmap' if they exist.
2016-04-29erts: Move option info for erts_mmapSverker Eriksson
from {allocator,mseg_alloc} to {allocator,erts_mmap}
2016-04-20erts: Produce statistics for literal and hipe super carriersSverker Eriksson
called 'literal_mmap' and 'exec_mmap'. Also moved existing erts_mmap info from 'mseg_alloc' to its own system_info({allocator, erts_mmap}) with "allocators" default_mmap, literal_mmap and exec_mmap.

2016-04-20erts: Make sure literal MBCs have super aligned sizesSverker Eriksson
on 32-bit, as the granularity of the literal bit vector is super-alignment.

2016-04-18Remove ?line macrosBjörn Gustavsson
While we are it, also re-ident the files.
2016-04-18Replace "%" with "%%" at the beginning of a lineBjörn Gustavsson
We want to re-ident the source files after having taken out all ?line macros. When re-indenting using Emacs, it's important that comments that should be at the beginning of a line (or follow the indentation of statements around it) must start with "%%".

2016-04-18int_SUITE: Fix interpretable/1 in a non-installed systemBjörn Gustavsson
interpretable/1 tests (among other things) that we are not allowed to interpret modules in certain applications (such as kernel and stdlib). int:interpretable/1 as currently implement enforces the restriction only in an installed system (the applications must have versions, such as kernel-1.2.3). We could modify int:interpretable/1 to enforce the restriction, but it could sometimes be useful to be able to debug (for example) erl_lint or other library modules that can safely be reloaded without crashing the run-time system. Therefore, assume that anyone working in a non-installed system knows what they are doing and fix the test case so that it stop failing in a non-installed system.
2016-04-18int_SUITE: Fix interpretable/1 on cross-compiled platformsBjörn Gustavsson
c7e82c6b406b teached the debugger to use the 'source' key in Mod:module_info/1 to help locate the source code corresponding to a BEAM file. The new test that was added at the same time will fail if the test suites were cross-compiled on another computer (i.e., the 'source' key would not point to the source file on the target computer). Avoid the problem by letting int_SUITE:init_per_suite/1 compile the BEAM files. That will ensure that 'source' keys points to the actual source file.
2016-04-15erts: Add 'exec_alloc' for hipe codeSverker Eriksson
that uses its own super carrier (erts_exec_mmapper) to guarantee low addressed and executable memory (PROT_EXEC). Currently only used on x86_64 that needs low memory for HiPE/AMD64's small code model. By initializing erts_exec_mapper early we secure its low memory area before erts_literal_mmapper might steal it.
2016-04-15erts: Make ErtsMemMapper able to map memory with PROT_EXECSverker Eriksson
to prepare for hipe native code allocation.
2016-04-15erts: Refactor callbacks for literal mseg allocSverker Eriksson
Make the callbacks more general to be usable for any allocator that that uses its own ErtsMemMapper.
2016-04-15erts: Tweak defaults for literal allocatorSverker Eriksson
Reduce main carrier size and number of free descriptors.

2016-04-15erts: Make trace_delivered go via sys msg dispatcher againLukas Larsson
This is needed as otherwise messages from system_profile will not be guaranteed to arrive before trace delivered.
2016-04-15erts: Add comment about future trace optimizationsLukas Larsson
2016-04-15erts: Optimize tracer reload testLukas Larsson
Without off_heap message queue the GC of the tracer could take very long and thus delay the code:purge which would in turn allow the trace generator to generate a lot of more messages which would make the tracer GC for even longer etc etc. The time taken for the testcase could go up to as large as 10 seconds and use lots of memory.

Any heap fragment created during a nif call to a tracer nif should be free'd immediately in order for the GC not to treat it as live data.

We have the main lock on rp->p, so why not?
2016-04-15erts: Silence harmless valgrind warning in dec_termSverker Eriksson
provoked by nif_SUITE:nif_binary_to_term. If we fail to decode an immediate (unsafe atom for example) with a dummy factory then hp and factory->hp will both be uninitialized and valgrind will complain about comparing them.
