Matt Pharr	5a53a43ed0	Finish support for 64-bit types in stdlib. Fixes issue #14. ... Add much more suppport for doubles and in64 types in the standard library, basically supporting everything for them that are supported for floats and int32s. (The notable exceptions being the approximate rcp() and rsqrt() functions, which don't really have sensible analogs for doubles (or at least not built-in instructions).)	2011-07-07 13:25:55 +01:00

Matt Pharr	b84167dddd	Fixed a number of issues related to memory alignment; a number of places ... were expecting vector-width-aligned pointers where in point of fact, there's no guarantee that they would have been in general. Removed the aligned memory allocation routines from some of the examples; they're no longer needed. No perf. difference on Core2/Core i5 CPUs; older CPUs may see some regressions. Still need to update the documentation for this change and finish reviewing alignment issues in Load/Store instructions generated by .cpp files.	2011-06-23 18:18:33 -07:00
