------- Comment #61 from dominiq at lps dot ens dot fr 2009-09-24 09:05 -------
I have followed a path different from the one in comment #58, trying to use
-gstrict-dwarf during bootstrap. For that I have made the following changes:
diff -uN ../_gcc_clean/config/mh-intel-darwin config/mh-intel-darwin

With these changes I have successfully bootstrapped revision 152076 on
i686-apple-darwin9 and I am currently bootstrapping revision 152100 on
powerpc-apple-darwin9 (modulo pr41457).
I have found that the change 'CFLAGS_FOR_TARGET += -gstrict-dwarf' is needed to
bootstrap, while the change 'CFLAGS += -gstrict-dwarf' (nor the others) does
not allow to propagate -gstrict-dwarf for the libraries, hence "Assertion
failed: (!"Unknown one-operand")..." for them.
