2013-12-02Remove uninitialized use of new_crr in erl_alloc_utilAnthony Ramine
When the offending code is reached, new_crr is either uninitalized or have been set to NULL. This patch removes the following warning: beam/erl_alloc_util.c:3510:6: warning: variable 'new_crr' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] if (!(flags & CFLG_FORCE_MSEG)) { ^~~~~~~~~~~~~~~~~~~~~~~~~~ beam/erl_alloc_util.c:3567:23: note: uninitialized use occurs here DEBUG_SAVE_ALIGNMENT(new_crr); ^~~~~~~ beam/erl_alloc_util.c:674:51: note: expanded from macro 'DEBUG_SAVE_ALIGNMENT' UWord algnmnt__ = sizeof(Unit_t) - (((UWord) (C)) % sizeof(Unit_t));\ ^ beam/erl_alloc_util.c:3510:2: note: remove the 'if' if its condition is always true if (!(flags & CFLG_FORCE_MSEG)) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ beam/erl_alloc_util.c:3438:23: note: initialize the variable 'new_crr' to silence this warning Carrier_t *new_crr, *old_crr; ^ = NULL

Bug never released.
2013-11-05Add switch for disabling sys_alloc carriersRickard Green
The switch "+Musac <boolean>" controls if sys_alloc carriers are allowed.
2013-11-01Ensure carrier pool only accessed by schedulersRickard Green
Disable carrier pool for the thread safe allocator instance 0. This since non-managed threads allocates and deallocates memory in this instance, and only managed threads are allowed to access the carrier pool.

2013-09-25Implement platform specific aligned sys_alloc and use when supportedRickard Green
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.

2013-04-15erts: Fix locking order violation for allocation wrappersSverker Eriksson
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.

2012-12-14erts: Optimize erl_alloc_util.c by substitute MBC_BLK_SZSverker Eriksson
with either MBC_ABLK_SZ or MBC_FBLK_SZ in all cases when we already know what kind of block it is.
2012-12-14erts: Fix bug when allocating size near sbc_thresholdSverker Eriksson
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).
