Workarounds are to define PNG_NO_MMX_FILTER_UP|AVG|PAETH (as in

pngconf.h) or to upgrade gcc to a newer version.

an official declaration.

This is your unofficial assurance that libpng from version 0.71 and

upward through 1.2.19beta31 are Y2K compliant. It is my belief that earlier

upward through 1.2.19rc1 are Y2K compliant. It is my belief that earlier

versions were also Y2K compliant.

of optimized features, see contrib/gregbook/readpng2.c in the libpng
|

source-code distribution.
|
||||
|
||||
It is also possible to disable or enable specific optimization features
|
||||
at compile time. To disable them entirely, which may result in slower
|
||||
but smaller and less complex and troublesome code, define
|
||||
|

PNG_NO_ASSEMBLER_CODE

||||
If you do this, then the run-time code for setting and querying flags
|
||||
described above, and the assembler code in pnggccrd.c or pngvcrd.c will
|
||||
not be built.
|
||||
|
||||
If you have disabled the assembler code, you can also disable the
|
||||
optimized C code, to obtain even slower but smaller code, by defining
|
||||
|
||||
PNG_NO_OPTIMZED_CODE
|
||||
|
||||
To disable only the MMX assembler code, define
|
||||
|
||||
PNG_NO_MMX_CODE
|
||||
|
||||
There are two versions of the MMX code: one for gcc compilers and one for
|
||||
MSVC compilers. Pngconf.h should automatically detect which you are
|
||||
using, and it will set either PNG_USE_PNGGCCRD or PNG_USE_PNGVCRD for you.
|
||||
|
||||
Define one or more of the following to disable specific parts of the
|
||||
assembler code:
|
||||
|
||||
PNG_NO_MMX_COMBINE_ROW
|
||||
PNG_NO_MMX_READ_INTERLACE
|
||||
PNG_NO_MMX_READ_FILTER_ROW
|
||||
|
||||
If the latter is not disabled, you can disable one or more of the
|
||||
individual filter types by defining
|

|
||||
PNG_NO_MMX_FILTER_SUB
|
||||
PNG_NO_MMX_FILTER_UP
|
||||
PNG_NO_MMX_FILTER_AVG
|
||||
PNG_NO_MMX_FILTER_PAETH
|
||||
|
||||
By default, libpng only enables the "sub" filter when gcc-3.x is used
|
||||
because experiments show that gcc-3.x produces bad code for the others.
|
||||
|
||||
When you disable various MMX features, libpng will still be able to decode
|
||||
files with those features. It will fall back upon the optimized C code
|
||||
or the unoptimized C code to decode them.
