# Compiler options: change them as needed. This mainly affects the speed of
# the JIT compiler itself, not the speed of the JIT compiled code.
# Turn any of the optional settings on by removing the '#' in front of them.
# You need to 'make clean' and 'make' again, if you change any options.
#
# Note: LuaJIT can only be compiled for x86, and not for x64 (yet)!
#       In the meantime, the x86 binary runs fine under a x64 OS.
#
# It's recommended to compile at least for i686. By default the assembler part
# of the interpreter makes use of CMOV/FCOMI*/FUCOMI* instructions, anyway.
CC= gcc -m32 -march=i686
# Use this for GCC 4.2 or higher if you don't intend to distribute the
# binaries to a different machine:
#CC= gcc -m32 -march=native
#
# Since the assembler part does NOT maintain a frame pointer, it's pointless
# to slow down the C part by not omitting it. Debugging and tracebacks are
# not affected -- the assembler part has frame unwind information and GCC
# emits it with -g (see CCDEBUG below).
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.
#
CCDEBUG=
# Uncomment the next line to generate debug information:
#CCDEBUG= -g
#
CCWARN= -Wall
# Uncomment the next line to enable more warnings:
#CCWARN+= -Wextra -Wdeclaration-after-statement -Wredundant-decls -Wshadow -Wpointer-arith

# Disable the use of CMOV and FCOMI*/FUCOMI* instructions in the interpreter.
# This is only necessary if you intend to run the code on REALLY ANCIENT CPUs
# (before Pentium Pro, or on the VIA C3). This generally slows down the
# interpreter. Don't bother if your OS wouldn't run on them, anyway.
#XCFLAGS+= -DLUAJIT_CPU_NOCMOV
#
# Disable the JIT compiler, i.e. turn LuaJIT into a pure interpreter:
#XCFLAGS+= -DLUAJIT_DISABLE_JIT
#
# Use the system provided memory allocator (realloc) instead of the
# bundled memory allocator. This is slower, but sometimes helpful for
# debugging. It's mandatory for Valgrind's memcheck tool, too.
#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.
#XCFLAGS+= -DLUA_USE_ASSERT
