44 it is linked to. This works only on ELF-based systems.

127 Enable validation code, which verifies that pointers reside within
128 jemalloc-owned chunks before dereferencing them. This incurs a minor

188 --enable-lazy-lock
189 Enable code that wraps pthread_create() to detect when an application
190 switches from single-threaded to multi-threaded mode, so that it can avoid
191 mutex locking/unlocking operations while in single-threaded mode. In
193 thread-specific caching is disabled.
195 --disable-tls
196 Disable thread-local storage (TLS), which allows for fast access to
197 thread-local variables via the __thread keyword. If TLS is available,
200 --disable-cache-oblivious
201 Disable cache-oblivious large allocation alignment for large allocation
203 large allocations are page-aligned as an implementation artifact, which can
204 severely harm CPU cache utilization. However, the cache-oblivious layout
209 --disable-syscall
214 --with-xslroot=<path>
218 --with-lg-page=<lg-page>
223 --with-lg-page-sizes=<lg-page-sizes>
224 Specify the comma-separated base 2 logs of the page sizes to support. This
225 option may be useful when cross-compiling in combination with
226 --with-lg-page, but its primary use case is for integration with FreeBSD's
229 --with-lg-size-class-group=<lg-size-class-group>
231 size. By default jemalloc uses <lg-size-class-group>=2, which results in
238 <lg-size-class-group>=3 results in e.g. the following size classes:
244 The minimal <lg-size-class-group>=0 causes jemalloc to only provide size
255 <lg-size-class-group> you specify cannot be supported. The limit is
256 roughly <lg-size-class-group>=4, depending on page size.
258 --with-lg-quantum=<lg-quantum>
268 This setting is architecture-specific, and although jemalloc includes known
271 <lg-quantum>. On most modern architectures, this mandates 16-byte alignment
272 (<lg-quantum>=4), but the glibc developers chose not to meet this
276 technically cheats if --with-lg-tiny-min is smaller than
277 --with-lg-quantum), but the fact that Linux systems already work around
280 --with-lg-quantum=3 during configuration, jemalloc will provide additional
281 size classes that are not 16-byte-aligned (24, 40, and 56, assuming
282 --with-lg-size-class-group=2).
284 --with-lg-tiny-min=<lg-tiny-min>
287 incorporated if <lg-tiny-min> is less than <lg-quantum> (see
288 --with-lg-quantum). Tiny size classes technically violate the C standard
295 The default of <lg-tiny-min>=3 works well in practice even on architectures
296 that technically require 16-byte alignment, probably for the same reason
297 --with-lg-quantum=3 works. Smaller tiny size classes can, and will, cause
303 value in [3, ..., <lg-quantum>].
