Summary |
0000379: FIXED: minor tweak in detection of IEEE special quantities |
|
Description |
Detection of IEEE special quantities in the 3.0.0.RC1 was unreliable when ALGLIB was compiled with heavy optimization settings (-xO5 for Sun Studio, -Os for GCC). In both cases subtle bugs in compilers was discovered (incorrect handling of volatile modifier; bugs when dealing with pointers to local variables).
In order to avoid triggering these bugs ALGLIB code was rewritten in a manner which was perfectly understandable by both compilers. |
