------- Comment #3 from jakub at gcc dot gnu dot org 2009-06-23 11:09 ------- I think if we don't want to emit .eh_frame, we should just default to -fno-dwarf2-cfi-asm. But if we do want to generate it, I fail to see what do we gain by also generating .debug_frame. Duplicating the same info, in one case in a more compat form, doesn't look like a good idea.
If we decide to teach gas to emit both .eh_frame and .debug_frame, or just .eh_frame, or just .debug_frame from CFI directives (controlled using some directive or option?), then one thing that needs solving is that gas will have to hardcode a register mapping table for ppc*, because on ppc .eh_frame uses a different register numbering from .debug_frame. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40521
