[LLVMdev] Boostrap Failure -- Expected Differences?

[David Greene]

The saga continues.

I've been tracking the interface changes and merging them with
the refactoring work I'm doing.  I got as far as building stage3
of llvm-gcc but the object files from stage2 and stage3 differ:


warning: ./cc1-checksum.o differs
warning: ./cc1plus-checksum.o differs

(Are the above two ok?)

The list below is clearly bad.  I think it's every object file in
the compiler!

I've attached the diff of an `objdump -x -d -D -s -g -t -r' on
alias.o from stage2 (stage2/alias.o) and stage3 (alias.o).

 From the objdump output, it appears the only differences are
in incidental symbol names (__FUNCTION__.<num> where <num> is
the difference).

Are these differences expected?  Should I run objdump with any
other options to further debug this?  When do I consider llvm-gcc
to be good enough (bug free) to submit my patches?  I obviously
want to do a complete testsuite run but I didn't want to start
that until I know how an llvm-gcc bootstrap should go.  If these
differences are ok, let me know and I'll start a testsuite run
and get these patches submitted.

Thanks.
