Subject: [PATCH] libgloss: add per-file & per-dir flag support
Date: Fri, 29 Dec 2023 20:56:30 -0500 [thread overview]
Message-ID: <20231230015630.23441-1-vapier@gentoo.org> (raw)
This logic is copied from what's used in newlib today. This allows
subdirs to easily define per-directory flags & per-file flags without
having to setup unique automake rules for each one.
