* Correct syntax erroreschnett2013-07-19

* Do not use type punning any moreeschnett2013-07-19
| | | | | | | | | | Do not cast between different pointer types. This is illegal in C/C++, and modern compilers (such as gcc 4.8) then generate wrong code. Instead, use memcpy to re-interpret the bit patterns of values with a different type. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/Vectors/trunk@85 105869f7-3296-0410-a4ea-f4349344b45a

* Various changeseschnett2012-02-05
| | | | | | | | | | | | | | | 1. Implement a simplified partial store interface Implement vec_store_nta_partial, which offers a simpler interface, similar to the one used in OpenCL. 2. Add kifmsg function, and implement kifpos and kifneg in terms of this. 3. Update (and make safer) Kranc-specific code git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/Vectors/trunk@47 105869f7-3296-0410-a4ea-f4349344b45a

* Support FMA4 instructions (AMD's fused multiply-add)eschnett2011-12-14
| | | | git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/Vectors/trunk@39 105869f7-3296-0410-a4ea-f4349344b45a
* Use "andnot" instruction when vectorisingeschnett2011-09-26
| | | | | | | | | | | | | Use the "andnot" instruction to reduce the number of different bit masks that are required. Using fewer different bit masks may require fewer registers to hold them, or fewer load instructions to access them, thus potentially improving performance. Do not scalarize ifpos when SSE 4.1 is not available; instead, use logical operations to create a bit mask. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/Vectors/trunk@31 105869f7-3296-0410-a4ea-f4349344b45a

* Make more C++ compilers understand the signbit functioneschnett2011-08-20
| | | | | | | | | | | | | Several C++ compilers cannot handle std::signbit; use a work-around instead. Correct a namespace problem when using the same identifier Vectors_SGN for different precisions (real*4 and real*8). Correct kifpos implementation incorrectly on several architectures. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/Vectors/trunk@29 105869f7-3296-0410-a4ea-f4349344b45a
* Use a macro name which is less likely to conflict with an existing macro.svn_bwardell2011-08-08
| | | | | | This macro is only used internally anyway. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/Vectors/trunk@28 105869f7-3296-0410-a4ea-f4349344b45a
* Add more vectorisation tests. Add test case.eschnett2011-08-08
| | | | | | | | | | | | | | Add vectorisation test for vector creation, load, and store statements. Convert C to C++ since vectorisation requires C++. Add test case. Beautify vectorsation templates. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/Vectors/trunk@26 105869f7-3296-0410-a4ea-f4349344b45a

| | | | | | | | | | | | | | Introduce configuration-time options for vectorisation, including options to allow architecture-specific choices that may influence performance. Introduce "middle" masked stores for large vector sizes and small loops. Clean up and simplify some of the implementation code. git-svn-id: https://svn.cct.lsu.edu/repos/numrel/LSUThorns/Vectors/trunk@10 105869f7-3296-0410-a4ea-f4349344b45a
