When testing this, I've noticed a major problem with Ada, supposedly on the
trunk as well when using latest binutils.
The problem is that gnat_init_gcc_eh which can change flag_exceptions is called

Is the target milestone 4.4.2 still true? In 4.4.2 20091008 the problem is
still present.
I have a patch for 4.4 which bootstraps and passes regression testing on

Put this in main.c and build it with a 4.4-branch compiler using recent
binutils:
int main ()

return 0;

I've been testing a backport of Jakub's patch to gcc-4.4, but it breaks
bootstrap on i686-linux with binutils-2.18.50.0.6 (Fedora 9) because stage1 gcc
outputs .cfi_sections directives even though the assembler doesn't

Yes, it is a bug and I'll change it, but I wonder why it makes a difference
(unless you're using PCH). .cfi_sections is only emitted if:
if (dwarf2out_do_cfi_asm ())
{

Ah, now I see it in the 4.4 version. Your backport is wrong then, you must not
return true from dwarf2out_do_cfi_asm when !eh_personality_libfunc, but
HAVE_GAS_CFI_SECTIONS_DIRECTIVE is 0 and not emitting normal

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,

I've confirmed that older GCC emits both .debug_frame and .eh_frame.
