Not at the moment, I'm afraid. If you want to contribute, the code for this is in pocl_llvm_api.cc's kernel_library() function. > ii) I saw from some discussions in this mailing list that there was a > proposal for adding support for multiple target CPUs (i.e. > kernel_*.bc). Is this still planned (or already supported)?

So if you wish to implement it, this feature is very much welcomed (especially from distribution binary package point of view it's crucial for performance). When we discussed this the last time, I scetched a plan for this (mainly as a description for a possible student project): https://github.com/pocl/pocl/wiki/Install-time-or-run-time-built-kernel-builtin-libraries BR, -- Pekka ------------------------------------------------------------------------------ BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT Develop your own process in accordance with the BPMN 2 standard Learn Process modeling best practices with Bonita BPM through live exercises http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual- event?utm_ source=Sourceforge_BPM_Camp_5_6_15&utm_medium=email&utm_campaign=VA_SF _______________________________________________ pocl-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/pocl-devel
