Introduce unconditional ERTS_ASSERT
and use that for both ASSERT and ASSERT_EXPR.

erts_sys_aligned_alloc() is currently implemented using posix_memalign if
it exist, or using _aligned_malloc on Windows.
If erts_sys_aligned_alloc() exist allocators will create sys_alloc
carriers similar to how this was done pre-R16.
|
|
|
|
|
|
That is, include information about carrier pool in result returned from
erlang:system_info({allocator,allocator_sizes, _}).

A cleanup after SBMBC was removed.
|
|
|
|
|
|
by putting blocks from different carrier into separate search trees.
Carriers are currently organized in a naive linked list by address order.

* sverk/win64-fixes:
erts: Change some more 'long' to pointer sized int (ErlDrvUInt)
erts: Fix crash in nif_SUITE for win64
erts: Fix assert in isdigit for negative characters

Some query functions in erl_alloc_util.c lock the allocator mutex
and then use erts_printf that in turn may call the sys allocator
through the wrappers. To avoid breaking locking order these
query functions first "pre-locks" all allocator wrappers.
|
|
Make sure each fix allocator type always allocate the right fixed size.
|
|
to replace macro constant ERTS_ALCU_DD_FIX_TYPE_OFFS.

with either MBC_ABLK_SZ or MBC_FBLK_SZ in all cases when we already know
what kind of block it is.
|
|
A block larger than sbc_threshold can be allocated in MBC if the subsequent
"residue block" is smaller than min_block_size.
Solved by lowering sbc_threshold to ("hard limit" - min_block_size).
|
|
No allocator strategy is using customized carrier headers anyway.
|
|
|
|
|
|
|
|
|
|
|
|
To get a consistent naming scheme where
FBLK = Free block
ABLK = Allocated block
|
|
|
|
by making use of the new block header scheme to find the carrier header
and thereby the allocator.
|
|
Make use of type FreeBlkFtr_t
Rename GET_MB_CARRIER into BLK2MBC (like BLK2SBC)
Remove some unused macros
|
|
to allow realloc to determine block size (in MBC or SBC)
without having to read the footer of the previous block
that might be written to by concurrent thread.

The enqueue operation have been re-written to behave better
during heavy contention by spreading writes over multiple
locations. This enqueue operation also take advantage of the
delayed aux work wake up functionality and can by this omit
one memory barrier.
|
|
As an optimization old thread progress data was kept and used in
handle_aux_work() in erl_process.c. This could cause memory to be
deallocated at a later time than intended, which is quite harmless.
This has, however, now been fixed.
|
|
* rickard/barriers/OTP-9922:
Reduce thread progress read operations in handle_aux_work()
Misc memory barrier fixes
|
|
- Document barrier semantics
- Introduce ddrb suffix on atomic ops
- Barrier macros for both non-SMP and SMP case
- Make the thread progress API a bit more intuitive
|
|
The incorrect assertion would fire when '+Muramv true' has been
given, i.e. when a reallocation always forces a move.
Change the assertion to not call the lock checker if the mutex is
not used (because the allocator will only be accessed from a
specific scheduler and thus no lock is needed).
