-gerrit commit 39ec7986f2ca4b24a2ffd9b3c9d869abd614212c Author: Patrick Georgi <[email protected]> Date: Sun Oct 7 22:11:07 2012 +0200 Drop ramstage.a ramstage.a has two issues: 1. duplicate source filenames don't survive the ar(1) treatment properly (so files aren't considered) 2. ld doesn't resolve symbols if it isn't forced to, in particular no overrides of weak symbols Downside: The resulting binaries get slightly larger. Link time optimizations should fix that, as would tighter rules in the build system (to not compile unused code in the first place).
