The -qstrict compiler option

A new suboption has been added to the -qstrict compiler option to allow more control over optimizations and transformations that violate strict program semantics.

-qstrict=vectorprecision disables vectorization in loops where it might produce different results in vectorized iterations than in nonvectorized residue iterations. vectorprecision ensures that every loop iteration of identical floating point operations on identical data produces identical results.

For detailed descriptions and usage information for this compiler option, see the XL C/C++ Compiler Reference.
