# makefile for libpng on Linux ELF with gcc using MMX assembler code # Copyright 1996-1997 Andreas Dilger # Copyright 1998-2001 Greg Roelofs # For conditions of distribution and use, see copyright notice in png.h # CAUTION: Do not use this makefile with gcc versions 2.7.2.2 and earlier. # WARNING: The assembler code in pnggccrd.c may not be thread safe. # NOTE: When testing MMX performance on a multitasking system, make sure # there are no floating-point programs (e.g., SETI@Home) running in # the background!
