worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Since the assembler part does NOT maintain a frame pointer, it's pointless

# Permanently disable the FFI extension to reduce the size of the LuaJIT
# executable. But please consider that the FFI library is compiled-in,
# but NOT loaded by default. It only allocates any memory, if you actually
# make use of it.
#XCFLAGS+= -DLUAJIT_DISABLE_FFI
#
# Features from Lua 5.2 that are unlikely to break existing code are
# enabled by default. Some other features that *might* break some existing
# code (e.g. __pairs or os.execute() return values) can be enabled here.
# Note: this does not provide full compatibility with Lua 5.2 at this time.
#XCFLAGS+= -DLUAJIT_ENABLE_LUA52COMPAT
#
# Disable the JIT compiler, i.e. turn LuaJIT into a pure interpreter.
#XCFLAGS+= -DLUAJIT_DISABLE_JIT
#
# Some architectures (e.g. PPC) can use either single-number (1) or
# dual-number (2) mode. Uncomment one of these lines to override the
# default mode. Please see LJ_ARCH_NUMMODE in lj_arch.h for details.

##############################################################################
# Enable these options as needed, but make sure you force a full recompile
# with "make clean", followed by "make".
# Note that most of these are NOT suitable for benchmarking or release mode!
#
# Use the system provided memory allocator (realloc) instead of the
# bundled memory allocator. This is slower, but sometimes helpful for
# debugging. This option cannot be enabled on x64 without GC64, since
# realloc usually doesn't return addresses in the right address range.
# OTOH this option is mandatory for Valgrind's memcheck tool on x64 and
# the only way to get useful results from it for all other architectures.
#XCFLAGS+= -DLUAJIT_USE_SYSMALLOC
#
# This define is required to run LuaJIT under Valgrind. The Valgrind
# header files must be installed. You should enable debug information, too.
# Use --suppressions=lj.supp to avoid some false positives.
#XCFLAGS+= -DLUAJIT_USE_VALGRIND
#
# This is the client for the GDB JIT API. GDB 7.0 or higher is required
# to make use of it. See lj_gdbjit.c for details. Enabling this causes
# a non-negligible overhead, even when not running under GDB.
#XCFLAGS+= -DLUAJIT_USE_GDBJIT
#
# Turn on assertions for the Lua/C API to debug problems with lua_* calls.
# This is rather slow -- use only while developing C libraries/embeddings.
#XCFLAGS+= -DLUA_USE_APICHECK
#
# Turn on assertions for the whole LuaJIT VM. This significantly slows down
# everything. Use only if you suspect a problem with LuaJIT itself.
#XCFLAGS+= -DLUA_USE_ASSERT
