# makefile for libpng on Linux ELF with gcc using MMX assembler code |

# 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! Context switches between MMX and FPU are expensive. |
