##############################################################################
# These options mainly affect the speed of the JIT compiler itself, not the

# removing the '#' in front of them. Make sure you force a full recompile
# with "make clean", followed by "make" if you change any options.

# Use this if you want to force a 32 bit build on a 64 bit multilib OS.
#CC= $(DEFAULT_CC) -m32
#
# Since the assembler part does NOT maintain a frame pointer, it's pointless
# to slow down the C part by not omitting it. Debugging, tracebacks and
# unwinding are not affected -- the assembler part has frame unwind
# information and GCC emits it where needed (x64) or with -g (see CCDEBUG).
CCOPT= -O2 -fomit-frame-pointer
# Use this if you want to generate a smaller binary (but it's slower):
#CCOPT= -Os -fomit-frame-pointer
# Note: it's no longer recommended to use -O3 with GCC 4.x.
# The I-Cache bloat usually outweighs the benefits from aggressive inlining.
#
# Target-specific compiler options:
#
# x86/x64 only: For GCC 4.2 or higher and if you don't intend to distribute
# the binaries to a different machine you could also use: -march=native

# Permanently disable the FFI extension to reduce the size of the LuaJIT

#XCFLAGS+= -DLUAJIT_DISABLE_FFI

# Features from Lua 5.2 that are unlikely to break existing code are

# Note: this does not provide full compatibility with Lua 5.2 at this time.

# 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

##############################################################################
# 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.
#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.
