| * Eliminate signed overlow in png_64bit_productJohn Bowler2016-12-262-20/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous version produced a signed overflow as a result of both the & 0xffff on the most significant bits of a negative argument; this converted (-1) into 65535 which resulted in a subsequent overflow. Since signed overflow is undefined in C90 the code has been modified to correctly calculate a signed result. This requires changing the 'hi' result parametr to a signed value. This has been code reviewed solely by the author. A further code review is highly desireable. Nevertheless the code compiles without warnings from clang and without the prior detection of an overflow. Since it no longer truncates any of the intermediate values this should be enough to ensure that it is correct. Signed-off-by: John Bowler <jbowler@acm.org>
| * Remove unsigned overflowJohn Bowler2016-12-261-5/+9
| | | | | | | | | | | | | | | | | | The previous code always results in an unsigned arithmetic overflow, this is well defined but produces errors from clang with the option to detect unsigned overflow. As the expression only gets evaluated once per row in this version of libpng it is easier just to rewrite it. Signed-off-by: John Bowler <jbowler@acm.org>
| * Remove 'defined' within macroJohn Bowler2016-12-261-2/+5
| | | | | | | | | | | | | | | | | | | | | | This removes the use of a macro containing the pre-processor 'defined' operator. It is unclear whether this is valid; a macro which "generates" 'defined' is not permitted, but the use of the work "generates" within the C90 standard seems to imply more than simple substitution of an expression itself containing a well-formed defined operation.
