Hi,
I assume that the following means the backends are not registred:
sequences for some float libcalls
-load=<pluginfilename> - Load the specified plugin
-march - Architecture to generate code for:
-mattr=<a1,+a2,-a3,...> - Target specific attributes
(-mattr=help for details)
When does the registration occur? During the build? If so there's a
problem with CMake for Visual Studio.
Or, is it something I need to do manually after building?
Thanks for any help. I'm too new at this.
