99118622ff Use nallocx() rather than mallctl() to trigger initialization.
Use nallocx() rather than mallctl() to trigger initialization, because
nallocx() has no side effects other than initialization, whereas
mallctl() does a bunch of internal memory allocation.

e2deab7a75 Refactor huge allocation to be managed by arenas.
Refactor huge allocation to be managed by arenas (though the global
red-black tree of huge allocations remains for lookup during
deallocation).  This is the logical conclusion of recent changes that 1)
made per arena dss precedence apply to huge allocation, and 2) made it
possible to replace the per arena chunk allocation/deallocation
functions.

Remove the top level huge stats, and replace them with per arena huge
stats.

Normalize function names and types to *dalloc* (some were *dealloc*).

Remove the --enable-mremap option.  As jemalloc currently operates, this
is a performace regression for some applications, but planned work to
logarithmically space huge size classes should provide similar amortized
performance.  The motivation for this change was that mremap-based huge
reallocation forced leaky abstractions that prevented refactoring.

fb7fe50a88 Add support for user-specified chunk allocators/deallocators.
Add new mallctl endpoints "arena<i>.chunk.alloc" and
"arena<i>.chunk.dealloc" to allow userspace to configure
jemalloc's chunk allocator and deallocator on a per-arena
basis.

ecd3e59ca3 Remove the "opt.valgrind" mallctl.
Remove the "opt.valgrind" mallctl because it is unnecessary -- jemalloc
automatically detects whether it is running inside valgrind.

"secondary" precedence is specified, but sbrk(2) is not supported.

e64b1b7be9 Enable big-endian mode for SFMT.

tests on e.g. MIPS and SPARC.

df3f27024f Adapt hash tests to big-endian systems.
The hash code, which has MurmurHash3 at its core, generates different
output depending on system endianness, so adapt the expected output on
big-endian systems.  MurmurHash3 code also makes the assumption that
unaligned access is okay (not true on all systems), but jemalloc only
hashes data structures that have sufficient alignment to dodge this
limitation.

ada8447cf6 Reduce maximum tested alignment.
Reduce maximum tested alignment from 2^29 to 2^25.  Some systems may not
have enough contiguous virtual memory to satisfy the larger alignment,
but the smaller alignment is still adequate to test multi-chunk
alignment.

Jason Evans
e3f27cfced Fix p_test_fail()'s va_list abuse.
p_test_fail() was passing a va_list to two separate functions with the
expectation that no reset would occur.  Refactor p_test_fail()'s callers
to instead format two strings and pass them to p_test_fail().

Add a missing parameter to an assert_u64_eq() call, which the compiler
warned about after the assertion macro refactoring.

b037a55f36 Restore tail call optimization subversion.
Restore the essence of 898960247a, which
sabotages tail call optimization.  This is necessary even when the
mutually recursive functions are in separate compilation units.

940fdfd5ee Fix junk filling for mremap(2)-based huge reallocation.
If mremap(2) is used for huge reallocation, physical pages are mapped to
new virtual addresses rather than data being copied to new pages.  This
bypasses the normal junk filling that would happen during allocation, so
add junk filling that is specific to this case.

2850e90d0d Remove flawed alignment-related overflow test.
Remove the allocm() test equivalent to the mallocx() test removed in the
previous commit.  The flawed test attempted to cause OOM due to large
request size and alignment constraint.  Although this test "passed" on
64-bit systems due to the virtual memory hole, it could pass on some
32-bit systems.

pass on some 32-bit systems.

898960247a Subvert tail call optimization in backtrace test.
Re-structure alloc_[01](), which are mutually tail-recursive functions,
to do (unnecessary) work post-recursion so that the compiler cannot
perform tail call optimization, thus preserving intentionally unique
call paths in captured backtraces.

f234dc51b9 Fix name mangling for stress tests.
Fix stress tests such that testlib code uses the jet_ allocator, but
test code uses libjemalloc.

Generate jemalloc_{rename,mangle}.h, the former because it's needed for
the stress test name mangling fix, and the latter for consistency.  As
an artifact of this change, some (but not all) definitions related to
the experimental API are absent from the headers unless the feature is
enabled at configure time.
