--- Comment #4 from Jorn Wolfgang Rennecke <amylaar at gcc dot gnu.org> --- Created attachment 50837 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50837&action=edit Proposed patch This patch fixes the problem for eSi-RISC and bootstraps on x86_64-pc-linux-gnu , with floating_to_chars.o properly built in each stage. Could you check that this also works for msp430?
