# Pragmas for RTL generation. Has to be an include, because user-defined
# pragmas cannot be exported.

# There are 3 different usages:
# 1) Ordinary imported code.
# 2) Imported from nimrtl.
#    -> defined(useNimRtl) or appType == "lib" and not defined(createNimRtl)
# 3) Exported into nimrtl.
#    -> appType == "lib" and defined(createNimRtl)
