Clean up configuration for backtracing when profiling is enabled, and
document the configuration logic in INSTALL.
Disable libgcc-based backtracing except on x64 (where it is known to
work).
Add the --disable-prof-gcc option.
Convert the man page source from roff to DocBook, and generate html and
roff output. Modify the build system such that the documentation can be
built as part of the release process, so that users need not have
DocBook tools installed.
Replace the single-character run-time flags with key/value pairs, which
can be set via the malloc_conf global, /etc/malloc.conf, and the
MALLOC_CONF environment variable.
Replace the JEMALLOC_PROF_PREFIX environment variable with the
"opt.prof_prefix" option.
Replace umax2s() with u2s().
Move the table of size classes from jemalloc.c to the manual page. When
manually formatting the manual page, it is now necessary to use:
nroff -man -t jemalloc.3
Remove medium size classes, because concurrent dirty page purging is
no longer capable of purging inactive dirty pages inside active runs
(due to recent arena/bin locking changes).
Enhance tcache to support caching large objects, so that the same range
of size classes is still cached, despite the removal of medium size
class support.
Don't look for a shared libunwind if --with-static-libunwind is
specified.
Set SONAME when linking the shared libjemalloc.
Add DESTDIR support.
Add install_{include,lib/man} build targets.
Clean up compiler flag configuration.
Add the --disable-prof-libgcc configure option, and add backtracing
based on libgcc, which is used by default.
Fix a bug in hash().
Fix various configuration-dependent compilation errors.
Add the 'G'/'g' and 'H'/'h' MALLOC_OPTIONS flags.
Add the malloc_tcache_flush() function.
Disable thread-specific caching until the application goes multi-threaded.
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.
