SDLSearch: Search for Static Device Library The search for SDL bitcode files is consistent with how static host libraries are discovered.

That is, the -l option triggers a search for files in a set of directories called the LINKPATH. The host library search procedure looks for a specific filename in the LINKPATH. The filename for a host library is lib<libname>.a or lib<libname>.so. For SDLs, there is an ordered-set of filenames that are searched. We call this ordered-set of filenames as SEARCH-ORDER. Since an SDL can either be device-type specific, architecture specific, or generic across all architectures, a naming convention and search order is used where the file name embeds the architecture name <arch-name> (nvptx or amdgcn) and the GPU device type <device-name> such as sm_30 and gfx906. <device-name> is absent in case of device-independent SDLs. To reduce congestion in host library directories, the search first looks for files in the “libdevice” subdirectory. SDLs that are bc files begin with the prefix “lib”.

Machine-code SDLs can also be managed as an archive (*.a file). The convention has been to use the prefix “lib”. To avoid confusion with host archive libraries, we use prefix "libbc-" for the bitcode SDL archives.
