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

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

This is your unofficial assurance that libpng from version 0.71 and

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.
