65b940a3c5 Loosen expected xallocx() results.
Systems that do not support chunk split/merge cannot shrink/grow huge
allocations in place.

6d91929e52 Address portability issues on Solaris.
Don't assume Bourne shell is in /bin/sh when running size_classes.sh .

Consider __sparcv9 a synonym for __sparc64__ when defining LG_QUANTUM.

This resolves #275.

0108b1fd04 Don't run stress tests as part of check target.
This change was intended as part of

target's dependencies.).

708ed79834 Resolve an unsupported special case in arena_prof_tctx_set().
Add arena_prof_tctx_reset() and use it instead of arena_prof_tctx_set()
when resetting the tctx pointer during reallocation, which happens
whenever an originally sampled reallocated object is not sampled during
reallocation.

This regression was introduced by
594c759f37 (Optimize
arena_prof_tctx_set().)

ea8d97b897 Fix prof_{malloc,free}_sample_object() call order in prof_realloc().
Fix prof_realloc() to call prof_free_sampled_object() after calling
prof_malloc_sample_object().  Prior to this fix, if tctx and old_tctx
were the same, the tctx could have been prematurely destroyed.

cec0d63d8b Make one call to prof_active_get_unlocked() per allocation event.
Make one call to prof_active_get_unlocked() per allocation event, and
use the result throughout the relevant functions that handle an
allocation event.  Also add a missing check in prof_realloc().  These
fixes protect allocation events against concurrent prof_active changes.

8f57e3f1ae Remove check_stress from check target's dependencies.
Prior to this change the debug build/test command needed to look like:

  make all tests && make check_unit && make check_integration && \
    make check_integration_prof

This is now simply:

  make check

Rename the check_stress target to stress.

676df88e48 Rename arena_maxclass to large_maxclass.
arena_maxclass is no longer an appropriate name, because arenas also
manage huge allocations.

a00b10735a Fix "prof.reset" mallctl-related corruption.
Fix heap profiling to distinguish among otherwise identical sample sites
with interposed resets (triggered via the "prof.reset" mallctl).  This
bug could cause data structure corruption that would most likely result
in a segfault.

b4330b02a8 Fix pointer comparision with undefined behavior.
This didn't cause bad code generation in the one case spot-checked (gcc
4.8.1), but had the potential to to so.  This bug was introduced by
594c759f37 (Optimize
arena_prof_tctx_set().).

c0f43b6550 Fix TLS configuration.
Fix TLS configuration such that it is enabled by default for platforms
on which it works correctly.  This regression was introduced by
ac5db02034 (Make --enable-tls and
--enable-lazy-lock take precedence over configure.ac-hardcoded
defaults).

4a2a3c9a6e Don't purge junk filled chunks when shrinking huge allocations
When junk filling is enabled, shrinking an allocation fills the bytes
that were previously allocated but now aren't. Purging the chunk before
doing that is just a waste of time.

This resolves #260.

6d8075f1e6 Fix chunk purge hook calls for in-place huge shrinking reallocation.
Fix chunk purge hook calls for in-place huge shrinking reallocation to
specify the old chunk size rather than the new chunk size.  This bug
caused no correctness issues for the default chunk purge function, but
was visible to custom functions set via the "arena.<i>.chunk_hooks"
mallctl.

This resolves #264.

30949da601 Fix arenas_cache_cleanup() and arena_get_hard().
Fix arenas_cache_cleanup() and arena_get_hard() to handle
allocation/deallocation within the application's thread-specific data
cleanup functions even after arenas_cache is torn down.

This is a more general fix that complements
45e9f66c28 (Fix arenas_cache_cleanup().).

5d2e875ac9 Add JEMALLOC_CXX_THROW to the memalign() function prototype.
Add JEMALLOC_CXX_THROW to the memalign() function prototype, in order to
match glibc and avoid compilation errors when including both
jemalloc/jemalloc.h and malloc.h in C++ code.

This change was unintentionally omitted from
ae93d6bf36 (Avoid function prototype
incompatibilities.).
