fa5d245aef Set default symbol visibility to hidden.
Compile with -fvisibility=hidden rather than -fvisibility=internal, in
order to avoid PLT lookups for internal functions.  Also fix a
regression that caused the -fvisibility flag to be omitted, due to:
    Port to Mac OS X.

cfdc8cfbd6 Use mremap(2) for huge realloc().
If mremap(2) is available and supports MREMAP_FIXED, use it for huge
realloc().

Initialize rtree later during bootstrapping, so that --enable-debug
--enable-dss works.

Fix a minor swap_avail stats bug.

aee7fd2b70 Convert man page from roff to DocBook.
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.

ce93055c49 Use madvise(..., MADV_FREE) on OS X.
Use madvise(..., MADV_FREE) rather than msync(..., MS_KILLPAGES) on OS
X, since it works for at least OS X 10.5 and 10.6.

e73397062a Replace JEMALLOC_OPTIONS with MALLOC_CONF.
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().

ac6f3c2bb5 Re-organize prof-libgcc configuration.
Re-organize code for --enable-prof-libgcc so that configure doesn't
report both libgcc and libunwind support as being configured in.  This
change has no impact on how jemalloc is actually configured/built.

9f3b0a74fd Fix tests build when --with-install-suffix is set.
Add test/jemalloc_test.h.in, which is processed to include
jemalloc/jemalloc@install_suffix@.h, so that test programs can include
it without worrying about the install suffix.

3395860921 Don't build with -march=native.
Don't build with -march=native by default, because the generated code
may perform especially poorly on ABI-compatible, but internally
different, systems.

fe5faa2cc5 Remove tracing (--enable-trace).
Remove all functionality related to tracing.  This functionality was
useful for understanding memory fragmentation during early algorithmic
design of jemalloc, but it had little utility for non-trivial
applications, due to the sheer volume of data written to disk.

b01a6c2057 Add JEMALLOC_PROF_PREFIX support.

filename prefix when dumping heap profiles, rather than "jeprof".

Add the --enable-prof and --enable-prof-libunwind configure options.

Add the B/b, F/f, I/i, L/l, and U/u JEMALLOC_OPTIONS.

Interval-based profile dump triggering is not yet implemented.

e476f8a161 Refactor jemalloc.c into multiple source files.
Fix a stats bug in large object curruns accounting.

Replace tcache_bin_fill() with arena_tcache_fill(), and fix a bug in an OOM
error path.

03c2237af3 Make malloc_stats_print() a public symbol, and make it repeatedly callable.

at least most events that have occurred thus far.

9ad48230ed Simplify JEMALLOC_ATTR_* macros to become JEMALLOC_ATTR().
Use JEMALLOC_ATTR(tls_model("initial-exec)) instead of -ftls-model=initial-exec
so that libjemalloc_pic.a can be directly linked into another library without
needing linker options changes.

Add attributes to malloc, calloc, and posix_memalign, for compatibility with
glibc's declarations.

Add function prototypes for the standard malloc(3) API.

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.

b7924f50c0 Implement configuration system.
Implement minimal Makefile.

Make compile-time-optional jemalloc features controllable via configure
options (debug, stats, tiny, mag, balance, dss).

Conditionally exclude most of the opt_* run-time options, based on configure
options (fill, xmalloc, sysv).

Implement optional --enable-dynamic-page-shift.

Implement optional --enable-lazy-lock.

Re-order malloc_init_hard() and use the malloc_initializer variable to support
recursive allocation in malloc_ncpus().
