  22 # These options mainly affect the speed of the JIT compiler itself, not the
  23 # speed of the JIT-compiled code. Turn any of the optional settings on by
  24 # removing the '#' in front of them. Make sure you force a full recompile
  25 # with "make clean", followed by "make" if you change any options.

  27 # LuaJIT builds as a native 32 or 64 bit binary by default.
  28 CC= gcc
  29 #
  30 # Use this if you want to force a 32 bit build on a 64 bit multilib OS.
  31 #CC= gcc -m32
  32 #
  33 # Since the assembler part does NOT maintain a frame pointer, it's pointless
  34 # to slow down the C part by not omitting it. Debugging, tracebacks and
  35 # unwinding are not affected -- the assembler part has frame unwind
  36 # information and GCC emits it where needed (x64) or with -g (see CCDEBUG).
  37 CCOPT= -O2 -fomit-frame-pointer
  38 # Use this if you want to generate a smaller binary (but it's slower):
  39 #CCOPT= -Os -fomit-frame-pointer
  40 # Note: it's no longer recommended to use -O3 with GCC 4.x.
  41 # The I-Cache bloat usually outweighs the benefits from aggressive inlining.
  42 #
  43 # Target-specific compiler options:
  44 #
  45 # x86 only: it's recommended to compile at least for i686. By default the
  46 # assembler part of the interpreter makes use of CMOV/FCOMI*/FUCOMI*
  47 # instructions, anyway.
  48 #
  49 # x86/x64 only: For GCC 4.2 or higher and if you don't intend to distribute
  50 # the binaries to a different machine you could also use: -march=native

 114 # x86 only: Disable the use of CMOV and FCOMI*/FUCOMI* instructions in the
 115 # interpreter. Do this only if you intend to use REALLY ANCIENT CPUs
 116 # (before Pentium Pro, or on the VIA C3). This generally slows down the
