--- Comment #16 from Iain Sandoe <iains at gcc dot gnu.org> 2012-01-30 21:24:07 UTC --- (In reply to comment #15) > Can you please mail me (or upload somewhere) all the RTL logs from > compilation with -fcompare-debug and -fdump-tree-optimized (both the non-gk > and > gk dumps)? will do tomorrow - a the moment, I think scratch the comments above, ... the stage3 output is not repeatable (c.f. the bootstrap ouput) using the command lines as I described (I guess because of the differences in the paths). However, the differences seem to be more than just strings - so I need to try and understand what's happening there. [the stage2 output *is* repeatable with ../stage1-gcc/g++ ... ] === I will repeat the experiment tomorrow using the stage2 .ii file .. out of time for today.
