What's the overhead with bootstrap-ubsan ?


I timed normal bootstrap and bootstrap-ubsan on x86_64, 24 cores,
Intel(R) Xeon(R) CPU X5670  @ 2.93GHz (aka cfarm 20) and the results:

--enable-languages=all

real	35m10.419s
user	204m5.613s
sys	6m15.615s

--enable-languages=all --with-build-config=bootstrap-ubsan

real	71m39.338s
user	347m53.409s
sys	7m44.281s

And don't underestimate the *usefulness* of this - if you don't have theresources to do a ubsan bootstrap, download mine from last night(x86_64-linux-gnu): http://moene.org/~toon/gcc-tests.log.gz

[ I hope there is a way to discard color codings when writing errormessages to a file, ugh ]


Kind regards,
