Code library not linked in lowering. Missing inline opportunity.

[sklam]

Throughout lowering, there are many invocation that may be uses code in another code-library but are not linking the dependency. This is leading to missed inline opportunity and potentially other issues in caching or AoT.

Example of code that needs updating:

numba/numba/lowering.py

Lines 860 to 865 in 3618091

	# Convert argument to match
	val = self.context.cast(self.builder, val, typ, signature.args[0])
	res = impl(self.builder, [val])
	res = self.context.cast(self.builder, res,
	signature.return_type, resty)
	return res

Should look like:

numba/numba/lowering.py

Lines 834 to 838 in 3618091

	res = impl(self.builder, argvals)
	libs = getattr(impl, "libs", ())
	for lib in libs:
	self.library.add_linking_library(lib)
