Add --with-jemalloc-prefix, which supports API mangling. Rename jemalloc_options-->malloc_options and jemalloc_message-->malloc_message.

Clean up the manpage and conditionalize various portions according to how jemalloc is configured. Modify arena_malloc() API to avoid unnecessary choose_arena() calls. Remove unnecessary code from choose_arena(). Enable lazy-lock by default, now that choose_arena() is both faster and out of the critical path. Implement objdir support in the build system.

Revert "Use ffsl() in ALLOCM_ALIGN()." This reverts commit 722b370399fd6734de6781285ce9a0cffd547bdd. Unfortunately, glibc requires _GNU_SOURCE to be defined before including string.h, but there is no reliable way to get the prototype within jemalloc.h unless _GNU_SOURCE was already defined.

#include <limits.h>
Add {,r,s,d}allocm(). Add allocm(), rallocm(), sallocm(), and dallocm(), which are a functional superset of malloc(), calloc(), posix_memalign(), malloc_usable_size(), and free().
2010-09-18 06:46:18 +08:00
#include <strings.h>
Add release versioning support. Base version string on 'git describe --long', and provide cpp macros in jemalloc.h. Add the version mallctl.

Add arena-specific and selective dss allocation. Add the "arenas.extend" mallctl, so that it is possible to create new arenas that are outside the set that jemalloc automatically multiplexes threads onto. Add the ALLOCM_ARENA() flag for {,r,d}allocm(), so that it is possible to explicitly allocate from a particular arena. Add the "opt.dss" mallctl, which controls the default precedence of dss allocation relative to mmap allocation. Add the "arena.<i>.dss" mallctl, which makes it possible to set the default dss precedence on a per arena or global basis. Add the "arena.<i>.purge" mallctl, which obsoletes "arenas.purge". Add the "stats.arenas.<i>.dss" mallctl.

Expose the memalign() and valloc() overrides even if --with-jemalloc-prefix is specified. This change does no real harm, and simplifies the code.
