# You can set/add options to CC and CFLAGS without editing this Makefile
# You have just to export an environment CC/CFLAGS variable before running
# make.
#
# Examples :
# $ export CC='gcc-3.1'
# $ export CFLAGS='-maccumulate-outgoing-args'
# $ make
# ...

# You can choose a specific compiler here removing the sharp symbol
#   - Default is 'cc' which is a symlink to your default distro gcc


# CC = gcc
# CC = gcc-3.1

# Assembler
AS = as

# Constants which should not be modified
CFLAGS += -DLINUX
CFLAGS += -DARCH_SPARC
CFLAGS += -DARCH_IS_BIG_ENDIAN

# Enable some experimental/debugging code
#   (Use only if you know what you're doing !)
    # PSNR during encoding
# CFLAGS += -D_DEBUG_PSNR

# Enable BFrame decoding (still beta)
# CFLAGS += -DBRAMES_DEC

LIBDIR = /usr/local/lib

  # Warning level options
      # Shows all warnings
  CFLAGS += -Wall
      # To detect non ANSI C code (xvid is not ANSI C (yet?))
  # CFLAGS += -pedantic


  # General Optimization options
      # Optimize code for size (implies -O2)
  CFLAGS += -Os
      # Unroll loops code, this might speed up loops
  CFLAGS += -funroll-loops
      # Generates FPU math code
  CFLAGS += -ffast-math
      # ??? (man gcc)
  CFLAGS += -fstrict-aliasing
      # Omit the frame pointer saving at function beginning
  CFLAGS += -fomit-frame-pointer
      # Generates Position Independant Code depending on your nasm version,
      # this could generate shared libraries that segfault because of a nasm
      # bug
  CFLAGS += -fPIC

  # Debugging and Profiling options
     # Writes debugging symbols in object files
  # CFLAGS += -g
     # Includes profiling code in generated code, don't forget to disable
     # -fomit-frame-pointer as these 2 options are exclusive.
  # CFLAGS += -pg
     # Precise profiling + test coverage (-pg must be activated)
     # Build the library twice and execute a program using the lib twice too
       # First pass : Will create sourcefile.da files to keep branch statistics
  # CFLAGS += -fprofile-arcs 
       # Second pass : Will create .bb and .bbg files suitable for coverage and
       #               branch probabilities during compilation
  # CFLAGS += -fprofile-arcs -fbranch-probabilities -ftest-coverage
