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.

6a0d2918ce Add memalign() and valloc() overrides.
If memalign() and/or valloc() are present on the system, override them
in order to avoid mixed allocator usage.

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".

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.

Fix API name mangling to coexist with __attribute__((malloc)).

03c2237af3 Make malloc_stats_print() a public symbol, and make it repeatedly callable.
Incrementally merge tcache stats, so that malloc_stats_print() always reports
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().

the critical path.

Implement objdir support in the build system.

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.

recursive allocation in malloc_ncpus().
