sandra at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sandra at gcc dot gnu.org --- Comment #3 from sandra at gcc dot gnu.org --- I think the right thing to do here is update the coding conventions. I've been using standard English rules for the adjective: hyphenated as an adjective phrase before the noun it modifies ("built-in function"), not hyphenated after the noun ("function X is built in to GCC"). But for the noun, "builtin" seems analogous to "runtime". In any case the noun usage "builtin" is already everywhere in the manual and it seems to me that replacing it with "built-in function" would add verbosity without making the documentation any easier to parse.
