Looks good to me. Btw, do the new dg-lto-warning/message directives handle fat LTO objects correctly where diagnostics usually appear twice, once for the fat part generation and once for the ltrans part? I wonder if we can build upon those new directives to finally add scan-lto-tree-dump for dg-final as well... (the complication here is to get at the dump file name but if we know the link stage is executed we can provide a prefix to the driver IIRC). Richard.
